Here’s a step-by-step guide for printing etch resist directly to copper clad boards. Two methods of making printed circuit boards at home have long dominated as the favorites; using photo-resist ...

If you’ve ever tried to build a printed circuit board from home, you know how much of a pain it can be. There are buckets of acid to lug around, lots of waiting and frustration, and often times ...

The two diagrams above are of the same circuit for a simple night light. How it works: when darkness falls on the light dependant resistor (LDR), its resistance increases causing a higher voltage ...

Printed Circuit Board (PCB) Design is an asynchronous online hands-on project-based course that provides instructions on the entire design capture process, starting with the User Interface, Project ...

To combat this, scientists at the Dresden University of Technology have created a biodegradable circuit board using a tree leaf. Although not currently as robust as typical printed circuit boards ...
