David Ye of hacker collective Split Reaction (who built the fully automatic BB gun we posted earlier this week as well as helped build the Mega Claw featured in the World Maker Faire) created a nichrome wire cutter, using an unlikely material for the frame — Lego.
Lego bricks are great for making models, but sometimes you can make real tools with them. If you want to work with foam you should definitely consider building this hot wire cutter. Its a great tool because it doesn’t leave any dust and it cuts through foam like butter. A few years back I didn’t have any scrap wood but I had plenty of Lego pieces.
