Fresh hacks every day
Couch potatoes have a new line of defense thanks to this remote-controlled turret. The gun itself is a hacked down airsoft model. The mount started with a servo motor in the center of a plastic cake box. A thin strip of plywood was added, along with a couple of sliding furniture feet to stabilize the platform as it rotates. A second servo mounts to that platform, which allows the trajectory of … [Read more...]
Drag soldering works exactly as its name implies, by dragging a bead of solder across fine-pitch pins you can quickly solder an entire row.

He found that the easiest and cheapest way to get clean, reliable signaling was by using something that was already sitting on his desk - his PC. He found that the tone generator built into Audacity was quite useful, at least for generating waveforms at less than 20 KHz or so. Upon plugging … [Read more...]
[Atiti] has a bad habit of hanging on to old things. Some people call this sort of behavior “hoarding”, but around here we understand his affliction. It turns out that in his collection of old computer peripherals, he located a Thrustmaster Formula 1 racing wheel he used back in the day.
