I've got one of those somewhere in the attic. In a previous life we got a job lot of PCBs made and some steel boxes which we painted black. I fitted a microswitch to the bottom so that you picked it up to set it off and then put it down to stop it. If I remember rightly the original version got one of the patterns wrong but there was a mod.
I must search for it one of these days.
