 Bigger Bigger  Smaller Smaller  Reset Reset

OK, now I want to make something that didn't appear in tinyAVR Microcontroller Projects for the Evil Genius but probably should have.

I want to make a deadman switch, like in the movies.

You push the button, nothing happens, you let the button go, BOOM! (depending on what is attached to the output, of course).

Two more switches, an enable and a cancel button.  Those are not the issue.

I can't find a really cool switch for the main button.  It should be illuminated, momentary, really cool looking, and hopefully with a safety cover.

Any ideas where to look?

I would start by looking at toy stores.  You may find something close you need to modify.

OK, that is a good idea.  I've already ripped apart an Easy Button so I get the general concept.  Too bad that switch, while momentary, red, and 10 out of 10 on the cool factor, won't work for this project...

It IS a momentary switch, so it COULD work as a monentary switch, schematic-wise, but really there has to be a certain Hollywood look and feel to this project, see the top image.  It has to be a button on top of a stick or something similar, with the enable and reset buttons probably on the side.  The actual dead-man switch has to be big and hopefully blinky but it should not be as big as an Easy Button.

I'm starting to think something like this would be good, though it doesn't have a safety.  Maybe I could find a safety cover to go over it...

Maybe this switch on the side of the stick with a grenade pin as the enable and disable all in one, plus an extra blinky LED for when the pin is pulled.  I think that may work...
