We get it. Sometimes you need some light over your new Lou Reed poster but you’re too cheap to buy a black light. Keith Neufeld has got your back. He’ll show you how to build edge-lit Plexiglas strips out of CD case scraps using a white LED that is then heat shrinked to fit the end of each piece.
The result is an impressive DIY light show that you can arrange in any way you see fit. It’s more radiant than a black light and it shouldn’t cost you more than a few bucks to put together.
