Nick: If you're planning to do that, you're going to have a hell of a time with the toy as a base. See, the slider inside is two different sizes, plus has holes drilled into it, its a problem to take off without cutting off the brass piece of the slider, or popping the emmiter off, which will disconnect the wires. you'd also have to rework the battery compartment, as well as the placement (and probably the soundboard size, if the Tennant CO was any indicator. ). then rework the slider, so it actually extends and slides. as well as holding the soundboard in place, so you can have the microswitch in one place. It'll be far more work than I think you think it'll be.
