LED throwies are cheery glow-dots you can make in seconds from simple components and stick to any ferro-magnetic surface. But that's just the beginning — here's how to hack and modify them.
First make a basic LED throwie, and chain them up into big throwie "bugs." Then learn to hack the throwie with an On-Off tab so you can switch it on whenever you want.
For extreme weatherproof outdoor lighting, slip a throwie inside an Indestructible LED Lantern — it floats, survives rain and ice, and looks really cool in multiples, for lighting paths, patios, or anything you can think of.
