Does anyone know if any of the various ball top sticks available have a hollow shaft?.
I was playing with the idea of cannibalising the little fire buttons from a couple of old Atari 2600 joysticks and drilling recesses to mount them in the top of a ball top joystick, and dropping a suitable 'prodder' down the shaft to a microswitch.
Alternatively does anyone know of anywhere that manufactures button topped sticks for sale?.
