PnP Feeder Sets HowTo

This is a complete guide to how I create and use 3d printed feeder sets for cut tape components in a pick and place machine. With many low cost pick and place machines, like the LitePlacer I have, you can just stick the tapes to the work surface and get going. But I find this…

A pick and place machine for prototyping

I really love electronics and all the challenges that come with solving problems and inventing things that have never existed before but building prototypes–especially of PCBs designed for manufacturability with tiny ICs and passives: ugh! It was fine when I was making basic circuits, but hundreds of tiny pieces, painstakingly placed one by one… Life…

Controlling High Voltage Loads Using a Microcontroller

A while back, I had a project that required high-side switching of a set of pneumatic valves by a microcontroller. Because the loads were inductive (solenoids) and required a good deal more voltage than the microcontroller supply to activate (24V), I needed some kind of middleware between the Arduino and the valves.  I created a…
