I pulled apart the gun to see how this mechanism works. The gun pulls through a chamber of air when the lever is pushed down. It is then stored until the trigger is set off. I will attempt to mimic this mechanism.
I have been to the dump on three occasions now. I have been looking for old pressurized systems with valves. This will be used instead of springs to 'cock' my mechanism ready for the next 'fright.'
I collected an old coffee grinder which turned out to run off dc power, it was a bit on the dodgy side...
I collected an old 1985 nintendo 'zapper', it is a light emitting gun which was used for point and shoot games using crt monitors,

quoted from wiki:
When the trigger on the Zapper is
pressed, the game causes the entire screen to become black for one frame. Then, on the next frame, the first target area is drawn in all white as the rest of the screen remains black. On t
he next frame, the next target
area is
drawn in white. The Zapper detects this change from low light to
bright light, as well as which frame the change was detected. This is how the game knows which target has been hit. After
all target areas have been illuminated, the game returns to drawing graphics as usual. The whole process is almost imperceptible to the human eye.
I was hoping to use the light emmitter as a trigger. I need to do some more research into it.
I also uncovered a well used rc car without the remote control.
There are some good parts to salvage from it including an AC motor which is hooked up to a drivetrain. The front steering arms could well work as a switch. and its a good base to get my head into figuring out how all the electronics work within it.
