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. It’s 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.
Can you tell us a little bit more about the power supply you used for the wire cutter? I’d like to build one, but I’m trying to do it on the cheap.
I’d love to get a list of materials /bricks used and as Haasebert already mentioned, a guide for the power supply. Great work anyway! This has to be one of the greatest custom built gadgets I’ve seen in a while.
I built one for a little project I did a few years ago. http://www.teamdroid.com/archives/2009/01/01/diy-plane-from-a-broken-helicopter/
Worked very well! Go, go, LEGO!
I just used 4 rechargeable AA batteries I use to have a hand held nichrome wire cutter that used two D cells, but those are tough to find. I abandoned the smaller hot wire cutter since I’ve built a much larger one that is powered directly off an ATX power supply’s 5V rail.
Cool post. That’s funny because I broke a foam plane and added it into a rube gold berg. those things have awesome motors.
Great invention.I’m sure it will serve lots of purpose. Thanks for sharing
