Another quick and easy project, this time focused toward a simple robot that rocks a tank full of PCB etchant.
Anyone that fabricates their own Printed Circuit Boards (PCB's) at home will either have a commercial etching tank, or manually rock their etchant solution until the process is complete. Given the price of commercial models are anywhere between $70 and $150, I thought some DIY was in order here. For less than $20 in parts you can make your own PCB Rocker like this one that does the job just fine.Discuss this article in the forums (8 replies).
