Electromechanical Game: Running With The Bulls

[vime0 =http://vimeo.com/11700747]

We’ve been watching the progress of this build for a while on Flickr. It looks like they’ve finally completed the electromechanical game, Running with the bulls. Based off of the event by the same name, you have to keep your guy from being trampled by the bulls as the charge.  The entire bull structure is pulled forward on a timing chain with a stepper motor with each bulls individual side to side movement being servo driven. It actually looks kind of fun.

Biopunk Watch: Time, Temperature, Gaming

[Matthew Garten] built this watch based on an Arduino. The face is a small color display which allows you to choose to show time in digital, binary, or analog formats. In keeping with the recent trend here on Hackaday he has a glove-based add-on that has temperature sensors in the fingers; for Firefighters or those with nerve damage to their fingers (we’re thinking Darkman). For entertainment in any situation he’s included a trackball and the ability to play breakout or draw in 16-bit color. Details are scarce but apparently he’ll be sharing more soon. For now, watch the video after the break and think of ways to shrink this down into a nice package like the Pong Watch enjoys.

Wii Remote Connectivity For Android Devices

[Pikipirs] developed an app that lets you connect a Wii remote to an Android phone. After the break you can see it used with a Sega emulator. The button presses seem very responsive, making for a nice gaming addition if you care to carry around the Wiimote in addition to your phone. It certainly seems to work better than the Wii remote + iPhone hacks we’ve seen. Pick it up from the Android store or download the APK from the thread linked at the top. This is an alpha version so don’t be shocked if it’s buggy.

OpenGL On The Didj

[youtube=http://www.youtube.com/watch?v=nfXI0crLTBc]

[Losinggeneration] managed to get a homebrew OpenGL application working on the Didj. It’s nice to see the community driven work advance on this device but something else also caught our attention from the forum post. Another poster pointed out that [losinggeneration] has files in one of his directories called “glquake-didj” and “glquake-didj.dbg”. We hope that means a working version of Quake is on the way for the hackable handheld.

Transistor Fabrication: So Simple A Child Can Do It

If manufacturing printed circuit boards has become too easy you should try your hand at producing transistors. [Jeri Ellsworth] put together a collection of videos outlining the process. These go way beyond the IC fabrication we saw from her in the past. It doesn’t take much, a 1000 degree oven with steam option, silicone wafers, and a variety of chemicals. We’ve embedded the instructional video as well as two demonstrations of her N-style FET after the break. Continue reading “Transistor Fabrication: So Simple A Child Can Do It”

Nike + IPod As A Tracking Device

[Thomas] found a paper from 2006 that describes using the Nike + iPod system as inexpensive tracking devices. Yep, it’s old as dirt but we think it’s fascinating reading! [Scott Saponas] and his fellow authors take a hard look at the lack of security in the system in a twelve-page PDF. They cover several different ways to capture and track one of the $29 tags in someone’s shoe, including using the Gumstix reader above, or a slightly modified 3G iPod. If the sensors are not removed or manually switched off when not in use they can be picked up by any RF reader within range. Because the tags are cheap and available, one could be planted on an unsuspecting victim James-Bond-style. Maybe this is what prompted Apple’s half-hearted attempt to restrict hacking the devices to do things like unlock doors.

Of course if you don’t want to do the reading you could download their video presentation or just stream it.

Ghetto Repairs: Desoldering With A Candle

Yes, that picture you are seeing is serious. [Roland] needed a chip for a damaged piece of electronics. He was lucky enough to find one on an old board at a local shop. The problem was, he didn’t have the hot air gun to remove the chip the correct way. Instead, he simply cooked the board over a candle to melt the solder. Interestingly, after he cleaned the candle-cooked board, it looked like it survived without damage. The chip worked fine and fixed his problems. Sometimes, we just don’t have the right tools for the job.
