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:


    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.
