Ever sketch out an idea for a circuit on a napkin and then never did anything with it?
Now, with Circuit Scribe — a wonderful new project on Kickstarter — there’s no longer any excuse for getting those iterations going. Circuit Scribe is a rollerball pen that writes with conductive silver (and safe!) ink. It’s a marvelous way to draw your ideas for your circuits on a regular piece of paper, then immediately start testing the idea…using the paper sketch itself.
Goodbye breadboard, hello back-of-napkin prototyping.
