This is video 2 of 2 in my short series showing you how to build your own inexpensive, reliable, and safe power supply for heating the hot-wire for your foam-cutting equipment. Here is the parts list for items used in this build: MUST HAVE ITEMS: From Radio Shack... Enclosure (8"x6"x3", #270-1809) Transformer (25.2v, 2 amp, #273-1512B) Bind Post (#274-661) Banana Plugs (#274-721) From Lowes... Lutron Dimmer Switch (#D-600PH-DK) Nuts and bolts, or rivets for mounting components Additionally... An old AC power cord (2 or 3 prong) with appropriate plug Optional Parts I Recommend (from Radio Shack) Fuse Holder (#270-364) Fuse (250 volt, 2 amp, #270-1023) 120 volt Neon Lamp (#272-0704) For more information on this project, tune in to TheCrashCast podcast (in iTunes, or at www.TheCrashCast.com), episode #82. EDIT: A lot of people are sending me emails asking me technical questions about this design. Please note that I am NOT an electrical engineer and my knowledge in this area is quite limited. Following are the links to information that I based my design on: www.instructables.com www.charlesriverrc.org www.utahflyers.org Now if you want a power supply with LOTS of power, and have the savvy to build it, then I highly recommend your building one of these: www.nsrca.org I have one of these and use it for all of my wire lengths about 28".
