Hacking And Philosophy: Crackdown Part II

hnpHackerCrackdownP2

This week we’re back with Hacker Crackdown: Part II! The caliber of last week’s comments was exceptional, but the level of participation planed off, and I’ll risk a guess: The Mentor’s Manifesto was more likely encountered as part of any given reader’s childhood—or, if not, easily skimmed at just over one page long—and therefore drew more interest. Crackdown, however, is perhaps less familiar. You also needed to read over 50 pages for last week (100 for this week). I list these things not as an apology or a rationalization, but as an attempt to better serve the community by providing accessible content. If you can’t commit to a lengthy reading, that shouldn’t exclude your participation.

This week, I’m adjusting the format to focus on key quotations from the text. Never even heard of Hacker Crackdown? No problem! Stick with us after the break where you’ll find all the relevant issues in a brief outline, then join us in our discussion!

Hackaday Links: November 17, 2013

hackaday-links-chain

If you purchased a knock-off FM transmitter and were unhappy with its broadcast range [Thiagohersan] shows how to double the range with a simple transistor amplifier circuit. He also hacked it for used without the 12V car socket.

[Patrick Herd] had a project that required him to strip about twenty Mindstorm batteries from their plastic enclosures. It’s not too tough getting into them but it does require drilling out the plastic rivets. He made a jig and used a CNC mill to automate the process.

Speaking of CNC, [Bertho] added some abstraction to distance himself from what he calls the “50+ years archaic syntax and grammar that G-code programs have”. The project is a meta-compiler for G-Code.

If you need a cold one and don’t have a HaDuino on hand you’ll thank yourself for hacking together this five-cent workbench bottle opener.

Just make sure you do all the lathe work for a custom speaker enclosure before you start pounding back those brewskis. Not only does [Shaun’s] creation look modern and stylish, but it boasts more than enough power to bump some tunes.

Here’s a project that adds LED feedback to your XBMC installation. It uses a Raspberry Pi to run the media center software, and a script to monitor it and actuate the lights on an Adafruit add-on board. At first glance you may not think much of it, but this is all the logic control you need to automate your viewing room. Who doesn’t want a home theater that automatically dims once you’ve made your viewing selection?

And finally, [08milluz] snagged some reactive electronics in the form of Disney’s Mickey Mouse ears. Apparently they glow different colors at live shows and based on where they are worn within the park. He did a complete teardown to show off the hardware within. It turns out to be controlled by an MSP430 which are known for their low power consumption. [Thanks Spikeo55]

Fail Of The Week: Automatic Baby Rocker

fotw-baby-bouncer

The art of hacking requires you to straddle many different types of engineering. In this case, it looks like [Dan] could use a little bit of brain-storming on how to get this doubly-failed project back on track. Do go easy on him as he wasn’t the one that submitted the write-up for this week’s Fail.

Ask Hackaday: (How) Should We Control Kickstarter Campaigns?

Kickstarter campaigns helped bring new and innovative products to the market during these last years. However there often are failures that can happen at several stages. We’d like to hear your opinion about them and discover what you think could be done to foresee/prevent these kinds of bad experiences that damage the trust between individuals and funding platforms.

Post-funding failures

There are a few project teams that give up a few months after receiving the funds, like the people behind the iControlPad 2 recently (disclaimer: we’re not backers). Even if [Craig] stated that he would document the entire production process on film and be open about all the project life steps, that didn’t prevent the project from being dropped (oddly enough) exactly one year after they received the funds. The more the project was headed towards failure, less was the frequency of updates regarding the project’s current state. The official reasons for this decision were difficulties that arose with the chosen LEDs, we’ll let you make your own opinion by having a look at the updates section. Thanks [Nikropht] for the tipping us about it.

Pre-funding failures

What is happening even more often on kickstarter is (usually successful) campaigns being canceled by the website itself after a few people rang the alarm bell. This may be due to an unfeasible project idea, a fake demonstration video/photos or even an attempt to resell an existing item under a new name.

The best examples for the first category undeniably are free energy generators. Here is an indiegogo campaign which actually succeeded. The creators announced one month ago that the project is running a bit behind schedule (aha), that the machine will cost around $5000 and that they’ll “need the funds before they make the units”. What can be done to educate the public that such energy is not created out of thin air?

The second category includes the recently canceled LUCI advanced lucid dream inducer (thanks [Michael] for the tip), which ended 2 days before the deadline. Technical guys got skeptical when they saw that the electrode signals were amplified several feet from the brain with an audio amplifier. At first glance, this was the only sign that this project may have been a scam (let’s give them the benefit of the doubt). Further research indicated that GXP (the company behind the campaign) didn’t exist, and most of their pictures were photoshopped. Here is a link to a quick summary of the situation and if you want to be entertained we advise you to make some pop-corn and head to the comments section of the project. What’s terrible here is that backers started to turn against each other, as the company always had a ‘good’ explanation for all the backers’ questions.

At last, there are some persons that just make funding campaigns with already existing products. This is the case of the eye3 flying robot and the vybe vibrating bracelet (don’t order!). Note that all of them were successfully funded. The eye3 was created by the same persons that made LumenLab, a company that created the microcnc. You’ll find more details here. The vibrating bracelet was just this one, which would be made in different colors. We just discovered this website that covered both project in greater lengths as well as many others.

Kickstarter fraudsters

Scams can also happen on the backers’ side. Recently, a Kickstarter backer named “Encik Farhan” attempted to rip off many Kickstarter projects. A ‘credit card chargeback’ technique was used, were the backer would contribute to the campaign, receive his perk and later cancel his credit card transaction using diverse reasons. The money would later be taken from the campaign funding by the payment processor.

What can be done?

The examples cited in this article set precedents which may turn people away from crowdfunding. In your opinion, what could be done to prevent this? Another reason we ask is because Hackaday may launch a sponsored product soon, thanks to the new overlords. This hypothetical product would be designed with the Hackaday community in a completely transparent process.

In the meantime, if you find any perpetual motion machines on kicstarter or indiegogo, be sure to send them in. You may also want to checkout this website predicting the success probability of a given kickstarter campaign.

3D Printering: A Makerbot In Every School Follows The Oregon Trail

printering

Gather ’round, children and I’ll tell you a tale of how everyone from the ages of 16 to 40 has played Oregon Trail.

Back when Apple was just starting out, [The Steves] thought it would be a good idea to get the Apple II into the hands of schoolchildren across the United States. They did this with educational pricing, getting Apple IIs into newly created ‘computer labs’ in schools across the country. These new computers – from my experience, anyway – were used as a replacement for the old Selectric typewriters, and on rare occasions a machine that played the MECC classics like Oregon Trail.

Fortunately, a few students were bright enough and had teachers who were brave enough to allow BASIC programming, PEEKs and POKEs. This was the start of a computer revolution, a time when grade schoolers would learn a computer wasn’t just a glorified word processor or dysentery machine, but something that would do what you told it to do. For those kids, and I’m sure a few of them are reading this, it was a life changing experience.

Now it appears we’re in the midst of a new revolution. If this horribly named column isn’t enough of a clue, I’m talking about 3D printing. Yesterday, Makerbot announced they were going to fill in for Apple in this physical revolution by trying to get a Makerbot into every school in the country.

Ask Hackaday: Can You Hack An Appliance Into A Spy Device?

crackinGoodTeapot

A story surfaced a few days before Halloween on Russian news site Rosbalt (yep, that’s in Russian), claiming Russian authorities intercepted Chinese-made electric irons and kettles: each equipped with microphones and WiFi. You can read a summary in English on the BBC’s website. The “threat” imposed by these “spy appliances” is likely the result of gross exaggeration if not downright fear mongering against Chinese-made products. It’s not worth our (or your) effort to speculate on what’s really happening here, but the situation does present a fun exercise.

Say you wanted to spice up your pen testing by altering a small home appliance: how easily could you build it? Let us know in the comments which appliance would serve as the best “host” for the modifications and what features you would include. Could you manage all the components listed in the article–a microphone, WiFi (any chance of cracking unsecured networks?), plus some vague indication that it “spreads viruses?” There’s a video below with a few glimpses of the electronics in question, but unless you speak Russian it probably won’t offer much insight.

Retrotechtacular: Upgrading Train Signaling Before The Information Age

retrotechtacular-british-railway-signaling

What’s surprising about the subject of this week’s Retrotechtacular is that the subject is not from that long ago. But looking at the way in which the work was done makes it feel so far in the past. In 1974 the British Railways Board set out to modernize and interconnect the signaling system. What you see above is one of hundreds of old signal control houses slated to be replaced by an interconnected system.

These days we take this sort of thing for granted. But from the start of the project it’s clear how the technology available at the time limited the efficiency of the development process. We’re not talking about all of the electro-mechanical parts shown during the manufacturing part of the video. Nope, right off the bat the volumes of large-format paper schematics and logic diagrams seem daunting. Rooms full of engineers with stacks of bound planning documents feel alien to us since these days even having to print out a boarding pass seems antiquated.

With fantastic half-hour videos like this one available who needs television? We’d recommend adding this to your watch list so you can properly enjoy it. They show off everything; manufacturing the cables, stringing them between the signal towers, assembling the control panels, testing, and much more.
