We’re sitting in Chris and bunnie’s awesome silicon hacking workshop at ToorCon 9 right now. It’s going really great and we’ll be posting updates from the conference through the weekend. Let us know if the comments if your going to be here too.
Month: October 2007
Quarter Shrinker (can Crusher Follow-up)
[Paul Anderson] sent in this classic quarter shrinker after seeing the can crusher the other day. It’s another high powered pulse shot into a coil system, but uses a solenoid actuated spark gap switch to swith those sweet high voltages. The results are quite impressive.
Home Brewing Beer Brewery
I saw this last month in Popular Science, but it wasn’t online for a while. This (nearly) all-in-one brewery was built by [John Carnett]. It does everything but requires malt extract for now. It boils wort, cools it for fermenting, delivers the brew to the kegs and most interestingly to me – uses cold plate cooling to cool the beer just before it exits the tap. I’m pretty sure they’re using peltier junctions, but I’d like to know for sure. Props to [Nate] for inadvertently reminding me of the thing when he sent in this effort to brew beer inside a pumpkin!
Electromagnetic Aluminum Can Crushing
This has been around for a while, but we never covered it – and it’s friggin’ awesome. [jesse] sent in this crusher, but I featured this one due to a sort of draconian copyright notice on the former. The latter also uses some easier to find, hackable parts. They’re both built on similar concepts – use a large bank of capacitors to store up the energy needed, and deliver it in one large pulse to a coil electromagnet. The resulting force lasts for a short time, but is enough to physically crush an aluminum can inward without touching it. Yet another one has some more dramatic examples of crushed cans.
USB Driver Hacking
[qDot] sent in his efforts to hack the oddest USB interface I’ve seen. The game is played by relaxing, so the controller senses biometrics. His notes on his adventure in hacking a driver are a bit entertaining, and definitely interesting if you’ve considered doing a little USB driver hacking of your own. If there’s enough interest, maybe he’ll post some more code to get things rolling.
3D Video With Consumer Cameras
While perusing our photos from the Hooptyrides, Inc. tour you may have noticed [Eric Kurland]’s two handed stereoscopy rig. It’s constructed from two consumer grade Sony DV cameras. The problem with using two separate cameras to make stereo images or video is that a lack of clock sync will make objects appear out of their true position because of differences in framerate. To solve this problem Damir Vran?i? developed the 3D LANC Master. It reads the crystal frequency from one of the cameras and writes to the ram of the other camera using Sony’s LANC protocol. This constant monitoring keeps the clocks within +/- 3ms. The control box also has buttons to power on, zoom, and record in sync. The 3D LANC Master plans are completely open source and work with a large number of Sony cameras. We have more photos of Eric’s rig after the break.
Side Project: CNCBadges
Want something different for your latest PC? I’m starting to offer custom CNC cut case badges made on my mill. I’m starting off with 1″ x 1″ badges made from .125″ thick 6061 aluminum alloy. The test cuts above should give you a decent idea of what I’m talking about. (The edges are a bit rough because I need to order some proper engraving bits.) I’ve just about gotten the kinks out, so I’m going to start accepting orders now. Engraved badges are $6 and shipping’s just $1 in the US. Everything is very, very beta – let me know if you have any questions.
Eliot said that I could pimp my little venture if I give away some Hack-A-Day badges. So drop a comment – I’ll pick five or so at random (unless you’re a tool) to receive a free badge with the Hack-A-Day logo. I *might* consider offering Hack-A-Day badges to raise money for the EFF, but it’s still up in the air.
