With the high availability of low-cost modular electronic components, building your own little robot buddy is easier and more affordable than ever. But while the electronics might be dirt cheap thanks to the economies of scale, modular robot chassis can be surprisingly expensive. If you’ve got a 3D printer you can always make a chassis that way, but what if you’re looking for something a bit more artisanal?
For his entry into the Circuit Sculpture Contest, [Robson Couto] has built a simple robot which dumps the traditional chassis for a frame made out of bent and soldered copper wire. Not …read more
CNC Upgrade to Guitar Pickup Winding Machine

It’s a prime candidate for automation, and while [Davide Gironi] did exactly that, he wasn’t entirely satisfied with his earlier version. He now has a new CNC version that is more full-featured and uses an ATMega8 microcontroller.
[Davide Gironi]’s previous version took care of winding and counting the number of turns, but it was still an assisted manual system that relied on a human operator. The new upgrade includes …read more
