If you thought there wasn’t anything else to shove on the end of your iPod, [Alex] is here to set you straight. He used the DC power that’s available on the iPod’s dock to drive a cheap laser pointer. It’s pretty easy to do – just get a dock connector (sparkfun has em) and add a laser pointer module. If you’d rather access everything else, check out the super dock I put together a while back. Hit the read link if you’d rather see the picture in color.
Desktop Soldering Press
[kruser495] put up this interesting instructable on making a desktop soldering press out of a sewing machine pedal. It uses a big chunk of carbon to create a diy high power cold-heat style soldering surface. It doesn’t work until the top is pressed down to complete the circuit. Looks like it’s only useful for wire joins, but still pretty interesting.
Playstation Controller Interfacing
This is an older set of hacks, but I’m surprised we haven’t covered them before. The playstation controller is an interesting alternative to normal robotic controls. This PS1 controller to serial interface is based on a Motorola HC68 series micro-controller. This even simpler version only needs some diodes to interface with a parallel port. Probably more interesting is this how-to on using a wireless PS2 controller with a basic stamp II.
FIRST Robotics Regional – KC – 2008
When you’re issued safety glasses at the door, you know it’s going to be interesting. As promised, I’m checking out the FIRST robotics regional in Kansas City today. The competition is pretty fierce – not quite flame throwing battle bot action, but the kids have put together some pretty serious robots.
Read on for more pics from the competition.
FPGAs Rock
I was doing some project window shopping today, and FPGA’s came up on my list. [John Kent] put together a pretty impressive documentation set. He’s written up some of his own projects, some how-to’s and linked plenty of good information for the budding FPGA programmer.
Bad-ass Modular Snake Robot
[Andrew] sent in this sweet snake robot video. The snake bots are all about 36 inches long and built from lots of hitech servos and 6061 aluminum. The guys/gals at Carnegie Mellon have built quite a few of these, and I’d say that their work is paying off. They haven’t published much in the way of details, but it appears that the snakes are being computer controlled for faster behavioral development than an on-board mictrocontroller would allow. When I saw the snake motion I was reminded of the winner of the latest Tresser robotics contest – Phoenix. It’s a spider like bot based on servos, but with some very impressive motion programming that was designed with an excel spreadsheet.
Visiting The FIRST Robotics Regional This Friday
Just a quick heads-up. I’ll be checking out the FIRST robotics competition in Kansas City this friday. It’s a robotics comp between teams of high school students – and the prizes include quite a few scholarships. I know we’ve got some readers who are in the competition. If you see a guy with a Hack-A-Day sweatshirt/T-shirt on, say hi and I might hook you up with some stickers. My day job will be providing real-time video streaming of the event, so feel free to check that out.
