Galvanic etching

Alex BandarAlex Bandar September 28, 20076 comments

Alex documents a hands-on build of a cheap galvanic etching rig, transferring laser-printed toner to copper and driving the bath with a modified PC power supply. He walks through the process, missteps, measurements and fixes, including why you should reverse the image, iron before cutting, and use higher DPI. Practical etch-time estimates and simple tweaks make this an approachable DIY metalwork technique.

Alex Bandar kicks off his EmbeddedRelated blog with a personal introduction and a clear creative angle. A materials scientist by training, he describes how embedded control, art, and unusual hardware ideas are starting to overlap in his studio projects. It is less a technical deep dive than a promise of interesting experiments, feedback, and a few fun toys along the way.
