Wireless fireworks controller


[Tuckie] sent in his wireless fireworks controller. The electronic parts are off the shelf – a 12 channel relay board and remote provide the guts. He used a rock tumbler to mill the black powder needed to make the detonators. A combination of the fine ground black powder, nichrome wire and ping pong balls makes up the business end of each detonator. When a channel is selected with the remote, the relay is activated, current is sent to the detonator which is taped to the firework fuse.
