Scratch built jog wheel


[whatsisface] sent in his scratch built clone of a Griffin PowerMate. The PowerMate… is just a big knob, so it’s easy to see why more than one person has attempted this. [whatsisface] was inspired by a bit-tech post that did nearly the same thing, only they used the head out of a VCR for the knob. All the other components, like the optical encoder, are salvaged from a mouse, which we talked about in our scavenging How-To. He used a RC car tire for the actual knob. While we’re sure it works great in dirt, we’d probably go with the weight and inertia of the VCR head instead. Have a look at the video below to see the knob being used with the Volumouse software.

How-To: Scavenge a mouse for parts

Chris Kiick posted about swarm robotics earlier in the week and today publishes his first Hack-A-Day How-To.

Old computer mice are being abandoned in droves. They’re tossed out because of dirt, obsolescence, or for being entirely too beige. Anyone who has a computer usually has more than one mouse and you can get them for pennies, if not free just for asking. Fortunately for the discriminating (read: cheap) hacker, these little widgets are chock-full of project parts. Today’s How-To will dissect a computer mouse, extract the useful parts, and give some ideas about how to use them.

How-To: Where to find parts for your projects


Hunting down the right parts usually takes more time than soldering everything together. I can’t count the number of projects that I tried to build and couldn’t find some key component that’s no longer made. You can help put together a list of suppliers at the end, but the idea is to have a quick reference to get your projects rolling (saving your money for important things, like espresso). Even if you’re familiar with the usual electronics parts shops, chime in to help me create a list of the best suppliers to fuel those hardware hacking projects.
