Open Source Weapon Makes You Puke

[Limor] of Adafruit Industries and the Ice Tube Clock has made her own open source non-lethal weapon: The Bedazzler. After attending a conference by the DHS where she saw the big-budget Dazzler, she decided to make her own. Thirty-six LEDs, six switching FETs, a Boarduino, and a former flashlight later, the Bedazzler makes a better rave toy than a weapon. It doesn’t work as-is, but we figure it will only be a matter of time before someone hacks this to make people… umm hack.  See the video after the break.

    Should that be “Bedazzler” or “Beta Dazzler?”
    Also, don’t try this in public; it might give people with epilepsy a bit of trouble.

  2. techx says:

    were the chunks really necessary.. looks cool though, i’ll take 2

  3. nope says:

    oh god not another arduino post….

    but really. i dont think the 1 million dollar works either. any bright flashy light will give you spot blindness and a headache. 10+ minutes of exposure to headache source=nausea. not impressive tech.

  4. atombomb1945 says:

    I get headaches and shortness of breath when I see a simple strobe, but it takes like five minutes or more. Something like this would have to be almost instantaneous to work well.

    What did they call it in Minority Report? Puke Sticks? This is the first step.

  5. Voshkin says:


    I made a weapon!
    it makes you perform crazy sex acts.

    although it does not work…

  6. kburn says:

    das ist überkööl!!!

  7. zac says:

    @ atombomb – sick sticks.

  8. frollard says:

    The bylaw officer that stops by in here (911 center) has an led flashlight with a fast-strobe function (probably around 10 hz) like this and it does make you instantly incapable of preventing the vertigo. You wouldn’t make a very good sharpshooter or hand-to-hand combatant. It wouldn’t stop someone with an uzi from making you into swiss cheese.

  9. svofski says:

    For most HaD readers just showing the arduino would be enough to induce desired effect.

  10. xrazorwirex says:

    “any bright flashy light will give you spot blindness and a headache. 10+ minutes of exposure to headache source=nausea. not impressive tech.”

    Uh… and who paid for it?

    YOU DID!! YAY!! (no refunds)

  11. walt says:

    really? for as many times as i’ve been exposed to bright flashing lights in all colors and frequencies, you’d think i’d have been sick at some point.

  12. vic says:

    This kind of weapon should be fought against, not promoted … We’re lucky it’s patented or else they would have sold the kit too.

    And maybe it does not work as intended, but I’m pretty sure 36 super high intensity LEDs right in your eyes can cause some significant damage.

  13. therian says:

    horay, weapon against epileptics
    (I will go to hell for this joke)

  14. therian says:

    by the way as all leds have lenses, with powerful white leds it become dangerous if you eye right in focus of lens it can do serious damage

  15. M4CGYV3R says:

    36 LEDs aren’t going to hurt your vision, or make you puke. I’ve been a rave/club DJ for >10 years and I can say firsthand that’s not the effect it achieves. Let’s see them try to shut down a party with these – nobody would even notice.

    There’s a commercial light out that does something similar to this called the VUE (models 1.1->6.1) which just use a single huge fresnel lens instead of small focusing lenses. It’s a party light, not a weapon. (If you take off the 12″x12″ fresnel on the big ones you can burn people with a mag-lite though)

  16. M4CGYV3R says:

    Also, the one linked to here doesn’t work. The puking in the video was a joke, in case the OP didn’t catch that. Firsthand example of the difference between a million in research and a home tinkerer with patent info.

  17. CB says:

    In the scientific community, failures are just as important as the successes (although, the taxpayers tend to hate the failures that result in “wasted” money). The fact that they are trying to open-source technology that the government and other firms are putting together is a great service to humanity. Seriously, who wants their tax dollars going to a million dollar non-lethal flashlight when it can be made via home hacking. Kudos to them for giving it a shot, and I hope they keep open sourcing more projects and get some right!

    I still like the microwave pain gun (Raytheon) as a non-lethal weapon (although I’m sure this has ramifications with pace-makers and similar medical devices, which is why it might never be accepted as a proper crowd control device).

    Bust out the glow sticks.

    nnnts nnnts nnnts nnnts

  19. Ned Scott says:

    It was really cool until she said that it didn’t actually work…

  20. sneakypoo says:

    “each one has a lens that focuses the optics”… yeah…

  21. anonyme says:

    If you want to make fish seasick too, tune it to about 7-8MHz instead of 11-12MHz.

    And if you want something that really may work, turn on Pokémon episode 38 of season 1 (one of the ones that only exist in Japanese), and skip about twenty minutes into the episode.

  22. anonyme says:

    Sorry, Hz instead of MHz…

  23. PocketBrain says:

    @M4CGYV3R: The antidote is, ironically, ecstasy.
    @thedudefrommiamivice: Now I know how it’s spelled. I had always wondered about that.

    nnnts nnnts nnnts…

    Ads for Arduinos and projects that don’t work? Last week was sooo last week.

  25. jimmys says:


    I represent the estate of Ron Popeil and I have a cease and desist order against you for using my client’s world renowned and legally trademarked name – The Bedazzler.

  26. Ryan Finch says:

    jimmys: I came in here to point this out

  27. aztraph says:

    that would be kind of cool if you could bedazzle your coat with a bunch of LED hooked up to the bedazzler from ladyada and take that to a rave.

  28. smartazz says:

    @Jimmys: Even if you were serious, your case would be against the department of homeland security… good luck. lol

  29. jimmys says:


    Hey now, that’s an interesting idea. Take a genuine Ronco Bedazzler(tm) and see if there’s a COTS or inexpensively prototyped – clear epoxy is cheap and fast – LED that would be feed properly through the gun. I think the real thing folds metal to affix it to clothing so maybe the two LED leads could be tabs to achieve the same thing.

    You’d have to wire it behind the clothing but as far as clothing LEDs, it might be better than those large lillypad style LED patches.

  30. Paul says:

    @smartazz: not really

  31. Concino says:

    I think the beDazzler commercial with that red checkered jacket from 80s with bling is more puke educing. We should have all the law enforcement wear that. Problem is solved.

    PS. Department of Homeland security: I’ll only charge you for $500,000 for this. :P

  32. Drone says:

    An Arduino connected to LEDs. And it doesn’t actually work. HaD, you’re at new lows by friends.

    Oh yeah – Nobody mentions there might be a serious uV exposure hazard here.

  33. jproach says:

    Drone: did you look at the datasheet for the cree green LEDs? I don’t see any notable UV output.

  34. sl says:

    @jproach…white leds are a blue/uv emitter with a yellow phosphor coating, so they look white. I have no idea about uv leakage though.

    Also I got a flashlight for twenty bucks from dealextreme, runs on a lithium 14500 cell and it’s programmable for variable brightness and pwm. I can set it to strobe its 200 lumen led at 15hz, more than enough to disorient someone if you pull it out in the dark. Just sayin.

  35. adamziegler says:

    sl… which flashlight was it… link?

  36. tehgringe says:

    I find quoting – “My names Jimmy and I’ve got big balls” works well enough.

    I love how they have made an uber-strobe, HOWEVER, I love the fact that some old crusty tw*t managed to rip folks off for a cool million to make a strobe light.

    Thats the lesson to be learnt here folks, it might be pointless shit sometimes, but some dumb fucker will get all dreamy eyed over it and part with their cash for your arduino hot glued to a playstation controller and a couple of servors tacked on for good measure.

    I love – boo to the arduino nay sayers…

    Just the mere thought of spending a million dollars on a strobe light just makes me sick.

  39. Frogz says:

    hey everyone
    i just FOUND a weapon that makes you puke

    it works 9 times out of 10, just watch

  40. ngnate says:

    Hey!!! I just found the Brown Noise Frequency. SSSSHHHHH!!!!! Don’t tell anyone. Maybe I can get a $1,000,000 government contract to ‘wink’ ‘wink’ find a sound frequency that disables people by making them sh!t their pants.

  41. kurtis says:

    I definitely wouldn’t appreciate someone using their “flashy” new “weapon” on me. The seizure may not kill me but the fall definitely could.

  42. supershwa says:

    Look what I made, it doesn’t work!

  43. John Avitable says:

    It would seem to me that this would only work for someone who is epileptic.
