Initially, Jennifer Lewis, Brett Walker and Analisa Russo just wanted to create a basic tool that could help students get a grasp on what a circuit was and how electronics worked. They put together a quick-drying ink that could carry an electric current and worked up some very cool magnetic components that could snap right onto whatever conductive doodling students would come up with. They set a decently ambitious goal of $85,000 for their crowdfunding campaign and let their idea loose on the masses.

As of this article, well over 9,000 people have jumped on board — and not all of them can be science teachers. Circuit Scribe is one of those inventions that goes exceedingly well with other successful DIY electronics kits, plus it gives enthusiasts the chance to snap up new components at the same time. Folks who already snatched up a Makey Makey or Arduino kit would be silly not to purchase a cheap Circuit Scribe kit.
