Graffiti briefcase for stealth tagging

briefcase-2

We’re floored by painter and engineer [Bob Partington's] graffiti briefcase, which proves how well art and tech can complement one another. Fear not, Arduino haters, [Bob]‘s case is an analog dream: no microcontrollers here.

The guts consist of 2 components: a linear drive system and a trigger assembly. The former takes advantage of a small RC motor with a chain drive which slides the can’s mounting unit along two stainless steel rods. The latter includes a custom wound solenoid plugged into a 24V cordless drill battery, which slams down 5 pounds of force onto the can’s nozzle to fire the paint.

This all fits into an otherwise inconspicuous looking briefcase to provide some urban camouflage. The final component is a stencil, which slides into a rectangular hole on the bottom of the case. The paint can sprays downward through the stencil and tags the ground at the touch of a brass button located near the handle.  [Bob] has plenty of other cool inventions you should check out that are less illegal. Or, stick it to the man by automating your tagging with Time Writer.

Thanks [David]

    Yay, make it easier for assholes to paint their stupid fucking “tags” on other peoples property.

    • Boo says:

      Well the device is interesting but yeah. Tagging to me is not art and people who do it deserve a sharp slap up the throat.

      • F says:

        just bypass the criminal justice system and go directly to the satisfaction of your tiny ego

        • hat says:

          I, for one, hope that they are simply punished to the fullest extent of the law… and that the legislature will see fit to make the crime of “tagging” punishable by amputating the hand of the perpetrator via the democratic process.

        • Patrick from Bethesda, Maryland - USA says:

          F – You seem to be “Pro-Tagging”. And yet, you have the nerve to talk about “ego”. That’s what tagging is all about – boosting the ego of the Tagger. Taggers are cowards. Calling it art is nothing but a Liberal/Democrat excuse to justify vandalism.

          • m1ndtr1p says:

            I love how you people bring political views into everything… If it’s something you don’t agree with, it’s automatically lumped into whatever political view you don’t agree with, even when it makes absolutely no sense (such as this).

          • Think what you will of Taggers, Liberals, Democrats, and Cowards- art doesn’t stop being art when it becomes offensive. It can be both art and wrong.

            Claiming something isn’t art does nothing to progress the discussion because it doesn’t make any value judgement of the thing or of art. In fact, the only thing I’ve learned from reading your comment is that there are many things you don’t like and tagging is one of them. Why should that affect my opinion of tags, tagging, or taggers?

          • Patrick from Bethesda, Maryland - USA says:

            Tagging is the exclusive domain of Young Immature Liberals like you. Conservative Republicans simply do not Tag. Unlike you – decent people respect property boundaries. Based on your comments – it is easy to infer your political affiliation. So, tell me please – am I right? You are a Democrat or a Liberal or Both – is that correct? Based on your comments – have I pegged you correctly?

          • @Patrick from Bethesda Are you asking me if I’m Dem/Lib? My Voter’s Registration card says Independent and I have a history of voting Republican. But I fail to see why my choice of politician should have any bearing over my comment.

            Art is Art whether or not you like it. That doesn’t make it okay, but it doesn’t make it not art.

            Also,

            > Conservative Republicans simply do not Tag.

            Fuck you. You think your shit doesn’t stink? Do you think any Dem/Lib President in America’s long history tagged? You political affiliation has nothing to do with the caliber of your character.

      • moot says:

        I don’t really mind the odd large stencil here and there but tags are just ugly.

    • vpoko says:

      Ha, somehow I don’t think most taggers are going to be building one of these. This is almost like telling them, “I can do this better than you’ll ever be able to.”

      • Leithoa says:

        Most taggers will mock this. Though I don’t always see it, people take pride in their hand drawn tags and think of them as art. This is ‘just a stencil’ to them that anybody can print out and start spraying around.

        • F says:

          Because there’s no such thing as a hand drawn stencil

          • Leithoa says:

            A well drawn original piece cut into a stencil is still a stencil. You only get one shot at a hand thrown tag. You don’t have to show anyone your screw ups if everything’s from one stencil. I don’t get the tagging aspect of graffiti, pieces I can respect.
            I do like the deployment options this stealth stencil-er opens up however.

        • kb says:

          Don’t tell Banksy that.

          I also mostly dislike taggers. I would suggest that the people who defend them open up the walls and driveways of their homes for taggers to use.

          • Kevin Keith says:

            Banksy is such a hack. His generic “f**k the police,” shtick is both adolescent, and tiring.

          • Replying to you because I can’t reply to [Kevin Keith].

            Read the following from Banksy. Maybe it doesn’t make you feel differently, but it resonated with me and doesn’t seem adolescent or tiring.

          • Kevin Keith says:

            Replying to Chris Knowles,

            I’ve seen that, and in fact, it was solidified my negative opinions of him. Apart from the fact that the layout of that is hideous, it just reeks of some kid who watched Fight Club and thinks he’s got society “figure out” or whatever. So what, the horror of seeing an advertisement is “assault” now? Oh give me a god damn break. I don’t like to often bring this point up, because it can be used to just dismiss any complaint, but I guess I don’t understand as to how someone can be so oblivious to how lucky they are. Yeah, it must be REALLY tough living in a developed nation because like you have to see pictures and stuff. We’re not talking about obscenity here. Christ. The self-importance and indulgence is nauseating.

          • Snarky says:

            Fun fact: Criminal mischief (intentionally damaging someone else’s property without permission) at nighttime in Texas is an offense for which the use of deadly force is authorized. Not saying I agree with it, but it is interesting.

        • Steven-X says:

          This relatively simple technology is still light years beyond the comprehension of the basic street tagger. Most are marking the territory (much like a dog or cat). They may consider it art as most artists are dropouts who consider basic scribbles to be “creative” and trendy. But most are just gang-bangers, pimps or low-level drug dealers. The only legit purpose for this sort of device is to frustrate the gang-based taggers (they would never figure this out!) with the idea that a new gang of ninjas are moving in on their turf.

    • Nikios says:

      Nothing about this incredible design makes it easier for “assholes to paint their stupid fucking tags on other peoples property”. But it seems like you could use some more creativity and art in your life to help with that attitude problem

    • F says:

      Isn’t it terrible, when public spaces are ruined by idiots plastering their obscenities on the wall?

      • hojo says:

        I think you meant this to be sarcasm, but yes, it is terrible. Taggers are garbage. They need to serve jail time, but it’s difficult to enforce.

        • F says:

          The criminal justice system has many mechanisms at its disposal including fines, probation, etc.

          I think you are the one who NEEDS for them to “serve jail time”.

          Of course you also make the brash assumption that the property owner is going to press charges! Or perhaps they should just be thrown directly in jail without pressing charges or prosecution?

          • hojo says:

            The problem is that taggers are fundamentally vandals and hippocrits. I have no doubt that most taggers have property that they would not want other people to alter or decorate without their permission, but they are not willing to extend that same courtesy to others. Our society has laws to protect people’s property. They should be enforced. It’s the carrot or the stick. If they can’t be taught to respect the property of others, then they need to be taught to fear them.

          • F says:

            “Our society has laws to protect people’s property. They should be enforced. ”

            How about those laws concerning vigilante justice? You have said repeatedly that you want to take the law into your own hands.

          • hojo says:

            I’ve never once said that.

          • F says:

            hojo says: “They need to serve jail time”

            Thus hojo becomes police, judge and jury all at once.

          • hojo says:

            Offering my opinion about what the law should be or about enforcing existing law is fundamentally different than administering my own punishment outside of the law. Even you ought to be able to understand that.

          • echodelta says:

            In Indiana get caught, go indirectly to jail mandatory. Cop shop first. No questions.

          • F says:

            then your opinion includes vigilante justice

            here is another opinion: “they should be prosecuted to the full extent of the law”

            can you see the difference?

          • vpoko says:

            F, what hojo wrote and how you interpreted it are so completely different that I’ve actually considered the possibility that I’m dreaming and this conversation isn’t happening. Any reasonable person could take it as a suggestion that taggers be dealt with in the framework of our criminal justice system pursuant to the laws at the time that they allegedly commit the act. You brought vigilantism into this on your own, completely out of left field. Wow, just wow.

          • F says:

            “deserves a sharp slap in the throat” is NOT justice, it is good old-fashioned Calvinist Christian “punishment” mentality. It has nothing to do with “justice”.

          • Mental2k says:

            You’re not even a very good troll are you?

          • Rob says:

            someone failed Trolling 101. might want to repeat that course. and plus also, wth does ‘calvinist christian “punishment” mentality’ have to do with this discussion? it’s something with which I have no small familiarity (understatement of the decade), but I fail to see any connection here.

      • 0x17h says:

        How are names considered “obscenities”? That makes no sense.

    • alan says:

      If corporations and rich people can pay to have their messages shoved in my face, then I have every right to do the same to them.

      Fuck advertisements. Combat them with art, or your own message.

      • hojo says:

        Fine, just pay the rent to put your message up, just like all those corporations do. I hate advertising as much as anyone, but vandalizing someone else’s property makes you a piece of shit. Advertising on someone else’s property after compensating them may be annoying, but it’s an entirely different and less vile scenario.

        • gravatas says:

          Nobody paid me for my bandwidth, ram, and proc cycles that are used by advertisements, including this site. I consider that a form of stealing and vandalism as much as anything else. People may chose to advertise on my property only on my terms, yet it is both a social and legal norm to expect businesses to skirt around such terms of use while mandating lawful enforcement of those terms on everyone else.

          My point is, very little advertising is actually paid for in full by the advertiser. If someone chooses to socialize the cost of their messages by putting messages on things they do not own, they are merely following the example of corporations.

          • Mulvane says:

            Well, all those sites you visit could become paywalls and you could then pay for the ability to browse them. Advertising is the transparent paywall many sites live off of so if you visit it, don’t like it, don’t go back. I block ads mostly and a lot of other content, but I don’t complain about the fact that it exists to help make the net a more free place overall.

          • I lie on the internet says:

            They’re not stealing bandwidth from you, the advertisements are part of the content that you’re getting.

        • Matt Owen says:

          @hojo – hear hear. I totally agree with you.

          Tagging a badly written version of your ‘nickname’ isn’t art it’s vandalism, plain and simple.

          That said, those large graffiti pieces – well some of them are quite skillful and can be considered artistic (although mostly not to my taste).

          I also don’t think that banksy is clever. His concepts are nicely artistic, but I do feel he should have done them on large canvas, instead of curbs and low walls.

          On-topic. Briefcase is cool – I can think of legitimate road painting requirements that could (and probably already do) use something like this.

        • Gatorade doesn’t pay rent for the bottles littered across the sidewalk. Pepsi doesn’t pay to be on the menu of of every restaurant that doesn’t have coke. Apple *gets* paid for putting glowing apples all over a college campus.

          The more important issue is not that American Apparel paid rent on a webpage, but that they didn’t pay rent to get into my eyes. This is isn’t a Legal complaint with the premise of advertising, it’s a Moral one. Legal loopholes and lopsidedness are everywhere- we know it isn’t okay for Apple to patent rounded rectangles in our hearts; we don’t need proof that they did or didn’t do it legally.

          It’s the same with ads and tags. They are visual stimulus that made their way into your head. Which is more important- whether they paid for the space or whether or not you find it offensive?

          Some ads and tags are genuinely offensive. They impinge on my experience for that day, coloring my life. Sometimes they give me headaches, like “HEAD ON, APPLY DIRECTLY TO THE FOREHEAD”. Sometimes they show me something grotesque that I don’t want to think about later but I can’t shake from my mind, like some misogynistic portrayal of a nude woman. Sometimes, it devalues the experience in the context it’s in, like acid sprayed on windows or shutters, or a billboard in a park.
          These are truly offensive, but money had *nothing* to do with it.

          Most mean very little really. A name painted onto a bench, whether with dripping paint or a phone number advertising their loans, affects me very little. Both parties just want to be seen. They ask for little and they take just as much.

          But every once in a while you find Art. Good Art. Something that makes you reevaluate what you thought about something. Something that makes you appreciate what you have or ease your troubles. In this case it’s easiest to see that rent means nothing because you want the beautiful landscape on the side of the building, the soothing tones over the radio, the uplifting message plastered on the phone pole.
          Who would be perverted enough to demand money to let an artist make people feel good.

      • Kevin Keith says:

        Yeah! Fuck advertisments! Fuck advertisements that support the very website I am commenting on right now!!

        Seriously, just grow up. Your angst-ridden teenage edginess is obnoxious.

        • shocked and annoyed says:

          while I may not agree with the original premise, I cannot agree with yours either. When I drive down the road I am traveling by my own will to a destination. The advertisements placed to distract drivers from their task at hand in hopes of gaining some small extra advantage within an industry are not in any way chosen nor desired by me as interruptions in my landscape. While the billboard owner may be thrilled Id rather see the trees. Not my option….not my choice.

          Now none of that goes to defend taggers……so please lets just keep that whine lubricated free from this….

          When I go to a website….that is my destination…..if the operators over monetize and the ads become excessive, annoying, and disruptive to my goals in viewing the site….Ill make the decision to move on…..as I have for that very reason from facebook. I will find other places for that purpose…..some sites realize this and even allow you to pay a premium to avoid such spammy corporate tagging.

          The real world advertisements are no more than tagging…..no more than graffiti, paying a fine in rent to a property owner for the privilege of not having it removed before it has infested the view of as many as the “artist” intended.

        • “War may sometimes be a necessary evil. But no matter how necessary, it is always an evil…” – Jimmy Carter

          Supporting HaD doesn’t validate ads. They’re still the disgusting byproduct of a “money is everything” mentality we live. It’s fine to be a realist and fall in line, but never fall so far you start to think that ads weren’t so bad in the first place.

        Alan – Your Occutard views are incredibly juvenile. Clearly – you will never grow up.

      • Patrick from Bethesda, Maryland - USA says:

        Alan – Advertising pays for Air-Time. So, in essence – what you are saying is that Radio and Television should be FREE !!! According to your Liberal Logic – Society owes you Free Entertainment with no strings attached. You clearly have no understanding of the business world. Liberal Democrat Retards like you want everything for Free. This includes Obama Care. Liberal Democrats want free housing too. You Occutards want everything for Free. Then you turn around and spit on society with tagging. Alan – your Left-Wing Democrat Socialism is disgusting. You need to grow up.

    • fartface says:

      The street and sidewalk ARE his property if he pays taxes. What would be cooler is he makes it tag with chalk so it’s non destructive.

      • Patrick from Bethesda, Maryland - USA says:

        FartFace – Graffiti Vandals do not “Own” the streets or the sidewalks. You are grossly misinformed.

        If what you said was true – then vandals would NOT be prosecuted when caught.
        The fact that they ARE prosecuted totally disproves your juvenile theory.

        You think like a typical uninformed Wall Street Occutard.

          You can only say things by attacking people. THAT is truly “jjuvenile. insulting people and catagorizing them with political views that have nothing to do with the subject, thats also extremely immature. Your the definition… of a fucking idiot.

  2. zosh says:

    In my personal opinion this kind of “tagging” has the artistic quality of a dog lifting its leg. Probably because it serves the same purpose.

    • hojo says:

      no need to qualify it. You can just say “tagging” and it still holds up.

    • F says:

      Do your posts count as “graffiti”? I find them to be offensive marks on a public wall.

      • hojo says:

        no, because I’m granted permission by the owner to post them, you simple minded tool.

        • F says:

          I did not grant you the right to put your offensive words on my screen so they are graffiti to me.

          • hojo says:

            That’s applies equally in reverse. You choose to view this website. You are free, and even encouraged, to direct you browser elsewhere.

          • F says:

            are you speaking as an authorized representative of this web site or are you once more pretending to have some sort of moral authority?

          • Patrick from Bethesda, Maryland - USA says:

            F is a tagger with a self-aggrandizing view of his criminal behavior.
            He has deluded himself into thinking that his juvenile scribble is actually art.
            In reality it is nothing but a public nuisance punishable by huge fines and/or prison time.

            This delusion is simply a cowardly method of justifying his poor behavior. As a coward – he naturally runs when cops approach. He won’t stand and face the consequences – no way, he’s a coward. He knows full well that he is breaking the law – so the coward within tells him to run.

            He now hides behind the internet and pounds his chest as if he is Andy Warhol or some other true artist.

            His comments are laughable because at the end of the day – F is nothing but a sissy with a can of paint.

            Hilarious !!!!

        • hojo says:

          I stating the facts.

      • zosh says:

        Do my posts count as “graffiti”? Probably. Do they count as “tagging”? I am pretty confident they serve an (if however insignificantly) higher purpose than “I was here”.

        Look, I am not arguing that this is a crime, as others do here. I am not arguing that graffiti is street art, I actually happen to like it if it carries any artistic value whatsoever. I am arguing that this and similar “tags” are literally nothing more than people marking their territory. And I will stick to my analogy: like a dog lifting its leg.

    • Animals leave marks, fact of life. Some do it by pissing on things, some by making comments online, some by making music, some by making paintings, some by making buildings or children or countries.

      Acknowledging this fact does nothing to suggest that graffiti is wrong, just that taggers exist somewhere on the spectrum between dog and founding father.

  3. Nick says:

    See what this needs is a way of holding the letters in a way that it doesn;t have a cross. Either like floss or something very thin that the paint can still adhere back to itself on whatever surface your spray

    • gravatas says:

      I can’t remember where I learned this, but in automated spray booths the thing to do is set back the support structure as far as you can and make it’s cross section perpendicular to the working surface as narrow as possible. With cone shaped output, over-spray (if that is the correct term) will obliterate the shadow of the support structure.

Their punishment would be extreme and harsh. Your Left-Wing/Communist/Socialist views are laughable. As usual, Democrats are detached from reality.

        well, not worse, but still terrible.

          • hojo says:

            I really hate it when my privately owned viaducts are vandalized with paints that probably adds to it’s surface protection. I mean, the functionality of the viaducts are greatly diminished by this nano-meter thick coating of material!! Really!
            As far as viaducts and all my other concrete structures go, they are the pinnacle of beauty when it comes to modern architecture and any random splash of paint renders them useless instantly!
            What are you whining about? Really.

          • Baz00 says:

            Dude, if you’re going to keep using the word “Hypocrite”, please spell it right.

        • hojo says:

          That’s a very specific (and bad) example. How you feel about the way graffiti looks is completely subjective. Why should a tagger be the one to get to decide how publicly owned property should be decorated? I prefer plain undecorated concrete to trashy spray paint any day, but I don’t get to decide either. If it’s publically owned, that means everyone’s opinions need to be considered, not just the tagger, and not just some guy who has to look at it.

    HaD readers really stink sometimes.

    Could be loaded with washable chalk marking paint, just for a ‘trail of breadcrumbs’ type of mark. Could be fun.

    Sure, taggers are irritating but humans have been making graffiti as long as we’ve been able to write and probably before. It isn’t going to go away if you shout at it.

    • sneakypoo says:

      There are a lot of bad things humans have been doing for millennia, that doesn’t make it ok.

      • SYNTRONIKS says:

        name one

      • F says:

        Graffiti on abandoned buildings is destroying our civilization! Woe is us!

        • hojo says:

          It’s not on abandoned buildings, it everywhere, and most importantly, it’s other people’s property. I hope somebody tags your car. You’ll have no right to complain.

          • voxnulla says:

            Let me get this straight. Because “F” defends this hack for what it is, which somehow is a unreconcilable difference of opinion between you two, you subsequently HOPE that his car is vandalized because of this difference? On top of that, you also see fit to be the arbiter on his right to form an opinion on that event, were it to happen?
            I don’t really think you are that property minded at all. Just a bit dim.

          • hojo says:

            You say I’m dim, but you’ve completely failed to comprehend the chain of reasoning here. I’ll break it down for you. I said nothing about the hack itself. I think it’s pretty cool. “F” didn’t say anything about the hack either, he made a sarcastic statement about Graffiti on abandoned buildings. I simply extended his statement to his own property. Put very clearly for the simple minded, “If you condone altering other people’s property without their permission then you should not have a problem when someone does it to your property.” It’s sometimes referred to as “The Golden Rule”. Once you understand it’s implications, you’ll be closer to understanding the irony of you calling me “dim.”

          • voxnulla says:

            I’m afraid you really are just a bit dim though.

          • hojo says:

            Neither “the numbers” nor this discussion supports that fear, so you can stop being afraid.

          • voxnulla says:

            I know that the emphatically… challenged have problems with this concept, but that was just a style figure. I do not really care about you being a small minded, self-centred nobody. I would if I knew that people like you could actually act upon your flaccid world views, but this mostly isn’t a problem. The few fruits that do fly a tad bit higher are easily spotted and marked.
            Do enjoy all the property friendly hacks you can find!

          • 0x17h says:

            You seem to hold property rights to be more important than human rights. You want to murder people for tagging.

            Typical right wing sociopath.

          • Kevin Keith says:

            My brain is starting to hurt trying to understand this idiocy. First of all, what on earth does this have to so with right-wing? Secondly, is it maybe, just maybe, possible that he didn’t literally mean that their hands should be cut off? Are you that dense? It’s called hyperbole.

        • F says:

          when I said “abandoned building” apparently I was talking about my car and my home

          • hojo says:

            You were talking about other people’s property. It’s a really simple concept.

          • F says:

            yeah there is no distinction between property owners who care and those who don’t

            it’s a crime even if the owner doesn’t care and will never press charges

            now I get it

        • hojo says:

          If they don’t care, then they’ll grant permission, and that’s fine. If you don’t ask permission, you’ve no way of knowing whether they care or not.

          • F says:

            how many years of college did it take you to figure this out?

          • hojo says:

            I had a grasp of these really simple concepts at an early age. I’m stating them for your benefit.

          • F says:

            and yet you are willing to lecture us endlessly about something that is plainly not your concern. Do the property owners of the world require your assistance in handling this apocalyptic issue or do you think they are capable of dialing the police themselves?

          • hugowesseling says:

            Reply to F:

            Your use of “and yet”, implies that the statement that hojo has a grasp of the concept of asking permission and is stating this concept to you for your benefit, is somehow clashing with your statement of his endlessly lecturing about his problems with tagging.

            This implication does not hold.

            Having scanned through more of your comments. A lot of them contain some form of either avoiding the point under discussion, or using sarcasm with extreme versions of other people’s statements to try and validate the negative of their actual statements.

            It seems that you are quite emotional about this issue, which might explain the lack of constructive commentary.

            One thing I hope you take from this, is that in general people disagree with your stance on the respectability of tagging. Which also explains the laws that have been set up to combat the activity.

  7. gajio says:

    That’s nice! I’d paint penises everywhere.

  8. MrX says:

    Don’t you think cities are already disgusting enough full of shitty tags and graffiti everywhere?

    • oodain says:

      depends, grafitti can be amazing, it can also suck,
      that said it has to fit with the area and some places would be ruined by it.

    • F says:

      Maybe we should tell the utility companies to stop doing it too, they put their marks all over the sidewalks too!

      Most advertising can also be classified as “graffiti”

      • alan says:

        Advertising IS graffiti. It’s just graffiti that costs a lot to make.

      • hojo says:

        What’s put up isn’t the problem, it’s who owns it, and do you have their permission to post there. I have no beef with any tagger who gets permission from the owner.

        • F says:

          maybe then you should mind your own business on a matter that concerns only the graffitist and the property owner

          • hojo says:

            I’ll share my opinion as often as I like, and if you don’t like it you can go fuck yourself.

          • voxnulla says:

            “I’ll share my opinion as often as I like, and if you don’t like it you can go fuck yourself.”
            I suggest you share this opinion at an event where it would actually be on-topic then. The hack remains valid despite your opinion on it’s uses or your thoughts on property.

          • Patrick from Bethesda, Maryland - USA says:

            “F” – I assume that “F” stands for “Fag”.

            Anyway, so which one are you – A property Owner or a Tagger who is going to have the shit beat of him when he gets caught?

            I suspect you are they asshole who’s destiny is to have the shit beat out of him.

            If you vandalized my property I would shoot you right on the spot.

            You are not an artist – you are a coward.

        • hojo says:

          As I’ve said before, I like the hack from a technical perspective. My opinions regard the human refuse that finds it appropriate to alter other people’s property without permission. Since you’ve made plenty of post seemingly defending tagging, I can only assume you agree.

          • F says:

            “seemingly defending tagging”

            Yes when I say that tagging is less bad than murder, I am saying that it is 100% okay.

          • voxnulla says:

            I’m afraid that a lot of others peoples property is seriously hampering some innate urges in some people, feeling the unnatural pressures of urban live, to express themselves like our rural and nomadic forefathers.
            In fact, denying these primal urges to “tag” in ones habitat by introducing a relative modern concept like “property” should be considered an infringement of basic human rights.
            Restricting the rights of self expression by proxy of this so called ownership within a living community is unnatural and should be a criminal act.
            Either you have property and participate in this naturally formed ritual act that has formed man-kind for aeons, or you fuck off!

          • hojo says:

            So you’d be totally ok with having your own property (house, car, etc) tagged in order to satisfy this primative urge? Or maybe you don’t have any property so you have no appreciation for the problem.

          • voxnulla says:

            I’m afraid (no, I’m not) that you fail to grasp the message yet again.
            When you called me “angry”, I assume you were just projecting. Have you talked to somebody about that behaviour? It’s not generally healthy.
            Apart from not being the sharpest tool in the shed, I think you have problems.

        • MrX says:

          I fail to see why anyone would let a stupid kid paint a ridiculous handle into their mailbox, wall, sidewalk or even door. Graffiti can be pretty cool when painted in proper places but tagging? It is just vandalism made by kids who do not have anything better to do.

      • hojo says:

        I think you have a need to discredit me, because I’ve uncovered your broken rationalization of bad behavior, so now you need to convince others, and perhaps more importantly yourself, that I’m the one with the problem so that you don’t have to examine the defects in your own character.

        • voxnulla says:

          “I think you have a need to discredit me,”
          I observe you make random assumptions, which would party explain your behaviour.

          • hojo says:

            I don’t think you now what random means.

          • voxnulla says:

            “I don’t think you now what random means.”
            The word was chosen very explicitly. A short run down of you argumentative errors will show that “random” is the correct term for your assumptions. They follow no logical/rational pattern.

  9. SuperNurd says:

    I don’t think it is a wise idea to film yourself committing a crime, and then release the video. Unless of course vandalism or “tagging” is legal where you live.

    • SuperNurd says:

      I don’t mean this in a sarcastic way, I just would strongly recommend removing this video, though it may be a bit late. Also, in case anyone was curious I too don’t condone “tagging”, I find it to be a public nuisance.

      • steve says:

        well at least he posted it under a fake name….”Bob Partington” yeah right like that’s real

        Really tho…cool build…I might be against what it is for…but I like how it does it

      • F says:

        And of course you are 100% certain that the property owners in this case will vigorously prosecute any and all vandalism that is happening on their property.

        • SuperNurd says:

          No, but just because there is no resulting punishment, does not mean there was no illegal, or undesirable behavior. I also had not said that he is in any extreme risk of punishment occurring, there may be no one to see this who actually could pursue any legal action, but in that slight chance that such a thing occurs, it is best not to flaunt the evidence that would prove you guilty.

          • F says:

            Maybe we need to remove all videos of people consuming alcohol

            -Perhaps all DRM avoidance hacks ass well?
            -Spudguns and gun hack in general, I’m sure the same red-necks who loath a bit of paint on an ugly sidewalk would hate for 3d printed gun hacks to be removed, although truly dangerous.

          • Not everything that is illegal is undesirable. Example: It’s illegal, though desirable, to put money in a parking meter that isn’t yours. It’s undesirable, though not illegal, to pee on the seat in a public restroom.

        • Nitish K.S. says:

          @F

    Mmmm, let’s see, electric motor, flammable vapor, confined space, what could possibly go wrong?

    Bits of metal shrapnel embedded in your legs from the knee down, not too good for running away after the explosion.

    Bonus, when it explodes, it’s now a terrorist destructive device, I’d bet that’s good for some prison time.

    I like the chalk idea posted earlier by andarb, as it’s not permanent and not explicitly vandalism.

    • shocked and annoyed says:

      ahh another brillant post from the HAD troubleshooting team.
      Guess what? spray paint vapor in a briefcase even in an ideal condition for detonation, which would require a great deal of air transfer, would produce insufficient force to even pop the latches on the briefcase.

      So for your tragically BS situation…you would almost have to ground the can, and have a hot line short to the can…..and even then….air fuel mix…the can rupturing would more likely drown the spark then be ignited by it.

      if by some amazing chance all the stars lined up…..and somehow the can actually did explode….the case wouldnt pass the metal….NO CHANCE…..a paper bag….possibly…a briefcase nope.

      Next….lets cover this terrorist destructive device crap your spewing,
      while perhaps, if you foolishly were tagging at a high value target, airport, government building, sporting event, etc, youd likely spend a day or two answering questions with HS….but as hard as it may be for you to comprehend….even the lowest level of technicians, with the most basic of experience, when given your “device” for analysis….will piss himself laughing. Even a momentary glance inside the paint filled briefcase will make it abundantly clear that any damage beyond the tag was the result of stupidity, naivety, and a kid playing around….not a terror cell,

  11. Wow – so much hate in the comments. It’s hardly the first quasi-legal HaD project, and I think it’s a pretty fantastic project.

    • F says:

      did you know that applying marks to the built landscape is a crime worse than murder?

      It’s too heinous for our justice system, witnesses MUST take the law into their own hands to save the poor concrete from humiliation.

      • edonovan says:

        If you travel through the city and see more tagging in one neighborhood than another, do you think “wow, this is a nice neighborhood; everyone is an artist”?

        All I think about are the delinquents who have no respect for other people’s property. I assume the area is riddled with thieves, vandals, and drug addicts. In my experience growing up in such areas, I’m not very far from the truth in those assumptions.

        Nefarious uses aside, this is an okay hack; but since I don’t do a lot of electronics work, I’m easily impressed.

    i would have probably gone for a stamp … if i had a penis small enough to find the need to put my name on everything

    • alan says:

      lol, the guy who made this obviously has a small penis lololol

      Except not. Just because YOU don’t want to tag things, doesn’t mean it’s stupid/pointless/wrong/”compensation”.

      • BiOzZ says:

        no, basic logic says its stupid/pointless/wrong/”compensation”
        putting your fucking name on things thats not yours just to have some poor man clean it up at the expense of everyone’s tax dollars
        you’re clearly trying to compensate for something when your this desperate for attention

        Your project idea……perfectly valid. Build it submit it. Make a statement through action. Because in truth, this isnt “build something janky with limited skills and knowledge.com” Its hackaday, notice the early pubescent feel of the webdesign?
        This site isnt an engineering convention….its a place where the halfbaked and nearly accomplished can win praise for having the masculine gonadality to either create something beyond your paygrade, or at least take something and bend it so hard into a new modality that you no longer have what you began with.

        If you want all safe sane and socially responsible projects……let your first post be your last. Thats not what this place is about.
        If you want anyone to take any notice of your feelings, beliefs, or opinions here or elsewhere I would highly recommend you make attempt to show your own worth before assaulting others’….at the end of the day, your ranting post holds no more weight here then a preachers ad on backpage.

          because applying paint to a surface is the same thing as endangering multiple lives

          • Kiel says:

            Nobody said it was. Grow up already. I’ve read you make the same asinine statements a dozen times in this thread. Painting something that doesn’t belong to you, especially with something as trite as a “tag” is disrespectful and has no purpose or artistic merit. Do you know what artists use “tags” for? To sign their art. I can call it wrong, I can label everyone that does it a moron. I can hope it is prosecuted. All without giving it a moral equivalence with anything else. Tagging isn’t art, it isn’t expression. It’s clueless adolescents thinking it gives them street cred.

          • F says:

            I’m still trying to figure out why this whole thing is of any concern to anyone besides the affected property owner. Why do you feel the need to get involved? What does your opinion add to the situation?

          • Kiel says:

            Maybe I am the property owner? What does your opinion add to the situation? Do you understand what happens when people discus things? They offer opinions and reasoning. Most of us don’t want to see “mista big” scribbled across everything we see and for the same reasons we don’t want to see litter all of the ground. It’s trashy.

            I don’t understand why you are so defensive about “tagging”. You keep trying to repeat why it’s no one’s business to offer their opinion but you continuously repeat yours.

    • F says:

      Apparently a machine that applies paint to the ground is to be considered in the same category as a terrorist missile.

      In the US of A (‘o thy land of the free’) getting drunk in public might be illegal, I don’t know, but where I live it certainly isn’t.
      Drunk driving, however, is as are certain other actions that one might undertake while under the influence of alcohol.
      Suffocating on your own vomit also isn’t illegal unless you live in a country in which suicide is illegal.

    • gravatas says:

      I’d be okay with that. The Pareto principle has been repeatedly proven right. Start with the biggest issues and work your way down. Alcohol is very, very high on the list of things that cause societal problems.

  26. david says:

    As a hack, the device is pretty sweet. It’s like the world’s most complicated / awesome stamp.

  27. Blufires says:

    This legal opinion battle is ridiculous. Tagging, although I hate seeing it defacing other peoples’ property, is as much an art form as Andy Warhol printing 4 copies of a plagiarized picture from the newspaper onto a canvas in different colors (about 80% of what he did).

    This hack is not specifically for the purpose of vandalism. Firstly, those upright paint cans 9 times out of 10 contain line marking paint, which is just water and chalk and washes off in the rain. Secondly, if I had a unit complex, I might want a cheap and easy way to write “rooms for rent $800/mo” on the wall outside. Much like cars, knives, spray paint and nitrate fertilizer, it’s a useful tool which can be misused.

    • Blufires says:

      Whoops, unit complex point refers to the wall writer robot. This could be quite a useful device for painting street numbers on the kerb though.

      I also forgot my other point. If this had an Arduino with wifi or bluetooth, it could make the user’s cell phone play a ringtone to cover up the spraying sound.

      • Nitish K.S. says:

        If you have to cover up the spraying sound it means you want to do something you don’t want others to notice. If it’s supposed to be a tool to be used with good intent then why would you want to do that ?
        If you want a cheap and easy way to write “rooms for rent $800/mo” on your own wall this is not it.
        And if you want to legally paint street numbers on kerbs all you need is a stencil and a spray can or any other source of paint.

    • shocked and annoyed says:

      thank you soooooooo much. I for one love andy worhol but….agree with the fact that the bulk of his work is little more than early advance photoshop. But it is art. Most things are….when viewed as the artist intended.

      Someone tell Banksy grafitti isnt art, better yet tell the millionaire collectors, and his agent.

  28. hue says:

    I sense a disturbance in the force……

    or maybe it’s just butthurt.

  29. Nice hack! All devices can be used for good or bad. If the stencil is nice or someone wants it, this is a great tool to have. For instance parking lot numbers on the floor, this case comes in pretty handy with the right stencils.
    It’s like saying 3d printers are bad because you can print a gun with it. It’s all about what the owner of the device decides to do with the tool. So for me. Nice build, ignore the haters and don’t stop being creative Bob!

    Also yes it bothers me that the media mentions nothing about a prosthetic hand that was made on a simple reprap 3d printer. While the whole world had to know some A-hole made a gun with it…

  32. Eirinn says:

    The hack is cool! Tagging in the other hand is not. I love graffiti, I really do, there’s a lot of insanely talented artists out there. Tagging was originally used, correct me if I’m wrong, as a form of signature for the art piece. Nowadays tags are plastered everywhere without purpose. I don’t mind graffiti, but tagging is like drawing a dick on your friends notebook – no one thinks it’s funny besides you :)

      If you have to spray crap on something you don’t own, it’s not art, it’s vandalism. There’s no talent, just a huge lack of common sense or respect for your fellow man. Is it really that hard of a concept to understand? Would you like me to spray paint this message on your house or car to make it clearer?

      Even little kids know it’s wrong to draw directly on the kitchen wall.

    also can we stop using the videos to share or show off music.

    i hate videos that are nothing but music.

    a couple second clip of a song in the beginning or intermissions is ok but an entire video

    if you are trying to exploit a loophole to post copyrighted stuff then try one of the many torrent sites out there and keep our beloved youtube free of piracy.

    And what is your people problem with vandalism? it’s just an art form, just like graffiti *trolling troll is trolling*

    Wow. I’m glad I never went ahead with an idea I thought of – or you guys would crucify me. Let me chuck it out there anyway…

    8 or so spray cans mounted under your car, spraying (water soluble paint of course) as you drive along. It could leave text on the road just like a dot matrix printer or POV display.

    The crayon on the wall he slashes
    Deep upon the advertising

    Of four letters

    The quality of comments and commenters sure has taken a dip recently.

    This is a fine hack. Pity about all the puerile dross in the comments.

    Is this HaD? or WWE Monday Night Raw?

  44. supershwa says:

    WOW! One helluva flamewar on this one!

    My opinion about graffiti artists/taggers is not important here. That’s not what hacking is about!

    Back to the subject: cool ninja hack, and not an arduino!

  45. I see that my subjects are running amok on this article. Go forth my trolls, throw down your gauntlets and continue to strike at all with your sharp words!

    DIY douchebaggery.

    I have some respect for graffiti artists, that is, people who make public art. But I have ZERO respect for douchebags who feel the need to mark their fucking territory, which is all this guy is doing. “oh look, the same exact mark, wherever I set down my briefcase full of ugly yellow spraypaint”.

    I’m back with one question for anyone who thinks this is ok (especially VOXNULLA). If I tagged your property……your house, your business, in/on your street so you can see it every day, with my tag, my art, or what ever you call it. Would you leave it in place? You preach to us, but just like every other church attendee, its only on Sunday and you practice what you teach when your in Church only. You are no different! Paint your tag on your own house and then be proud of your work….invite others to tag your house, your business, property, street. Be proud of what you do then, not in the shadows. Buy your paint , don’t steal it.

    So will you do this to your own property and be proud? If not, I say Fck you one last time……Cowards, Criminals, Vandals…..come clean my sh!t up.

    over and out! Later…..Much Later!

      No i would cover it up just like anyone else, then i would have beef with you in the graffiti chain slashing you until you either defended your name or disappeared.

      Yes. Why would you assume otherwise? Why would we be saying this if we didn’t believe it? This is a trump card, it’s evidence of how far apart we are. We can’t even wait for a response or imagine that someone else would think differently than you about graffiti. No wonder you sound like an ass- you think you’re talking to a bunch of hypocrites.

      But you’re not. Surprise! There are people that think, feel, and act differently than you do. And unfortunately your response to them, without ever waiting a moment to see if they’re real, is

      > Fck you one last time……Cowards, Criminals, Vandals…..come clean my sh!t up.
