Think Geeks Wants You To Have Broken Stuff

March 31, 2011 by Mike Szczys 13 Comments

Think Geek has a growing pile of returns and damaged product that they’re trying to get rid of. The purveyors of technological oddities, like any other large retailer, sometimes have stuff that doesn’t work right, or has been damaged somewhere between factory and consumer. The broken bits find their way back to the distribution center and now they’re stuck with the task of doing something with it.

They can’t sell it, and we’re happy to say they don’t want to throw it out. So they’re considering giving it away to worth-while causes like Hackerspaces and schools. Looks like no real details have been hammered out as of yet. But if you belong to a Hackerspace or other group that can find a use for this stuff, click-through the link above and sign up to let them know you’re interested. The goldmine of reusable stuff is located in Columbus, Ohio and pick-ups might be available. Otherwise they’re going to need to find a way to cover the cost to ship boxes to those interested.

Don’t forget to document your projects and let us know what you use this stuff for.

DARPA Needs Your Help! Design A Ground Combat Vehicle.

March 25, 2011 by Jesse Congdon 63 Comments

[Joe Schlesinger] of MakeIt Labs wrote in to let us know about an upcoming live chat session march 28th on IRC to discuss DARPA’s latest project, the Adaptive Vehicle Make.

DARPA, in the pursuit of innovative high-risk high-payoff tactical technology is looking to crowd-source the design and construction of the 3000-5000 parts that make up your run of the mill super advanced next generation military hardware. They are even going to distribute about a thousand 3D printers to schools, where students will compete to design some of the complex systems. The project emphasizes “not traditional” vendors (IE: Hackerspaces) and monetary compensation will be involved in the parts production process.

If you like acronyms (and who doesn’t), or feel like wading through jargon, check out their site. We also found the Wikipedia entry to be helpful in understanding what they are carrying on about. A briefing PDF (6mb) also contains a lot of information on DARPA’s plans, and pretty pictures.

As per usual DARPA plans on issuing several challenges to make up the entire project, all with huge cash prizes. The first two challenges last 9 months, starting with the Mobility/Drivetrain Challenge in the middle of 2012. The Chassis/Integrated Survivability Challenge starts in 2013. These first two also include a cash prize of 500 thousand to one million dollars. The third challenge, the Total Platform Challenge lasts 15 months and begins in late 2013 this carries a prize of one to two million.

[Joe]’s Hackerspace will be there, any chance we could help out?

Redbull Sends Marketing Doodad To Hackerspace Using An Open Source Product

Looks like Redbull is harnessing the power of open source hardware to market their product to hackers everywhere. We’d say that it worked because here we are, posting up some free advertising for them. It seems that a rep for the company dropped off a package at a hackerspace in LA called Null Space Labs. It came in what is obviously a laser cut wooden box, a material that tends to make hackers salivate. Inside they found the board you see above. It took a bit of time to look over the hardware was eventually identified as an Uzebox. Sure enough, then plugged in an original NES controller to the controller port on the back of the board and were playing a version of Pac-man in no time.

Marketing and advertising have their place in our lives which can be annoying and intrusive at times. But we have no problem with it when done creatively and targeted to our interests. Good job Redbull, and might we add, that’s a heck of a routing path for your PCB outline!

Geiger Counter A/D Conversion For Radiation Level Crowdsourcing

[Akiba] and the crew at Tokyo Hakerspace are still hard at work trying to help out their fellow countrymen after the recent earthquake, tsunami, and ongoing nuclear crisis in Japan. You may remember the group as they are behind the Kimono Lantern project we featured last week. This time around, their efforts are focused on getting usable information out to those who need it.

With all of the talk about nuclear fallout, they wanted to see what sort of measurements they could get in Tokyo, however they could not locate a Geiger counter anywhere nearby. Luckily, they were eventually able to source two old counters from the Reuseum in Idaho. One is being lent out to individuals in order to check if their home’s radiation levels are safe, but it was decided that the other would reside outdoors in order to collect radiation readings from the air.

[Akiba] wanted to put the results from the external Geiger counter up on Pachube, however these old units are all analog. He figured that a quick and dirty way to do analog to digital conversion would be to monitor the chirps coming off the counter’s speaker. This was done by wiring up an Arduino to the speaker leads, and keeping track of each time the speaker was activated. This resulted in an accurate digital radiation reading, matching that of the counter’s analog display. The Arduinio wirelessly sends the information to another Arduino stationed inside his apartment, which then uploads the data to Pachube.

A walkthrough of his conversion as well as the source code for both the Arduino counter and the Pachube uploader are available on his site, in case anyone else in the Tokyo area has a Geiger counter handy and wishes to do the same.

Tokyo Hackerspace Helping Disaster Victims

March 16, 2011 by Mike Szczys 36 Comments

We, like the rest of the world, have watched in horror as footage of the recent earthquake-caused disaster has been reported from northern Japan. It’s easy to watch video and see nothing but distruction, however, life goes on and [Akiba] is looking for a way to help the recovery efforts. He mentions that one of the big needs in the disaster area right now is for light, as the power infrastructure has been heavily damaged. The mason jar seen above is a Kimono Lantern that was meant to accent a garden at night. It has a solar cell – one NiMH rechargeable battery – and one bright LED along with a charging circuit. It was designed in the Tokyo Hackerspace and they released the build files in hopes that a large number can be donated to those in need. With a reasonable amount of daylight, the single cell battery can be charged enough to provide 10 hours of light from the little device.

How can our hacks help others? That question has been on our minds for the last few days. Light is a great first step. But we’ve also wondered about information networks to help coordinate rescue and cleanup workers. There are hacks that bring WiFi using wind power or solar power. What other hacks do you think would be useful to aid in the recovery process?

The Evil Genius Simulator: Kinect Controlled Tesla Coils

March 15, 2011 by Jesse Congdon 18 Comments

The London Hackspace crew was having a tough time getting their Kinect demos running at Makefair 2011. While at the pub they had the idea of combining forces with Brightarcs Tesla coils and produced The Evil Genius Simulator!

After getting the go ahead from Brightarcs and the input specs of the coils they came up with an application in Openframeworks which uses skeletal tracking data to determine hand position. The hand position is scaled between two manually set calibration bars (seen in the video, below). The scaled positions then speeds or slows down a 50Hz WAV file to produce the 50-200Hz sin wave required by each coil. It only took an hour but the results are brilliant, video after the jump.

There are all these previously featured stories on the Kinect and we’ve seen Tesla coils that respond to music, coils that make music, and even MIDI controlled coils, nice to see it all combined.

Thanks to [Matt Lloyd] for the tip!

Phillip Torrone Makes Case For Next-gen Public Libraries

March 11, 2011 by Mike Szczys 48 Comments

[Phillip Torrone] has started a discussion about a possible upgrade to the public library system in the US and wants to know what you think. His name should be familiar (Hackaday founder, Open Source hardware advocate, and Tron costume model) and he’s definitely got his finger on the pulse of today’s electronics enthusiasts. He poses the question, could we upgrade libraries to become public techshops?

As a frequenter user of my own library system here in Madison, Wisconsin I like to think that they’re not going anywhere anytime soon. I find it nice to be able to borrow books, as it seems wasteful to buy a book I will only read once. Sure, I do buy and sell books at the used book store, but that doesn’t diminish how I value the library system and often suggest in posts that our readers should go check out books they’re interested in.

But I must agree with [Mr. Torrone] that, a least to some extent, reserving large buildings to house collections of books may be an outdated concept. It’s not just the books that make the library. These buildings provide computer time and Internet access to the community. I’ve occasionally written posts from public libraries instead of paying the ‘coffee tax’ to get on WiFi in a coffee shop. Libraries also serve as community meeting spaces, and polling places. And what [Phillip] is talking about aims to offset some of the stacks in order to augment the functionality of the institution.

What if it were a repository of knowledge in the written form as well as a place to use tools and learn new skill? It’s an intriguing question and I’m glad he asked it.
