Longtime MAKE pal Raphaël Assénat wanted to recycle his stash of anti-static bags for component shipping, and built an improvised heat-sealer to do it. It’s just a step-down transformer, some current-limiting resistors, a momentary switch, and a resistance wire made by uncoiling a compression spring. [Thanks, Raphaël!]

Nice project. For anyone interested in store bought heating elements, I like:
http://www.duralite.com/metallic-elements.htm
They supplied the heating elements I wired to an Arduino to make an annealing oven for glass and tool steel. Good support, prices, selection and all that.
For more information about tool steel, visit http://www.simplytoolsteel.com We present tons of information regarding tool steels and their uses.
