The idea is to solder up some pre-made indicators with integrated resistors to save space on the breadboard when prototyping — instead of four slots, you only use two per LED.

He decided to build some simple, modular circuits on protoboard and make them easy to interface with the breadboard. As you can see, he ended up with seven modules that make prototyping faster and ...

PCB design is easy, right? To a certain extent that’s fair to say; with a growing number of schematic design and PCB layout packages available — normally integrated, increasingly free — almost anyone ...

Circuit Scribe is a rollerball pen that draws with conductive silver ink –no annoying breadboards involved. In fact, you can build a circuit with nothing but a coin, battery, paper clip, and LED.
