After building my Piccolo and playing around, I really don’t like the software. It’s certainly simple and hackable and does a lot of what I need to do, but something about the Arduino/Processing pair don’t quite work for me. Fortunately it’s just a bunch of servo motors, and I already have the PIC code in… Read More: Hysterical »
Aw yeah, CNC day. Pretty simple parts, I guess it wasn’t strictly necessary to use a CNC, but hey, it was there. Here it is coming together. A spaceship! ~~~~ Brief interlude ~~~~~~ Laser cut Piccolo parts. And the rest of it. Rough-ish final box. And it flips… Read More: CNC Day »
During my research on how others have handled the sparking circuit in an EDM, I’ve been fairly unimpressed. Off the top of my head, there was one 555-based pulsing EDM circuit, one purely analog circuit that was never built, and one hand modulated system attached to a drill press. It’s hard to tell exactly what… Read More: First Burn »
Other than wanting to spend very little money on this project, the scope of it is huge enough that I’ve been trying to use as many prebuilt components as possible. If I have the majority of the project build with discrete, modular components, then I can start drilling down and replace the weakest links, one… Read More: Start small. »
One of my theories for rapid PCB prototyping is EDM, or electro-discharge machining. The idea behind EDM is that you have an electrode hooked up to negative voltage, dunk the system in a high impedance fluid, and then put a potential on the metal workpiece. When that electrode is close to the metal and the potential is high… Read More: EDM Prime »
