Hi, I'm new here. I am looking to make a small laser crab (link to specs) light more interesting. The unit I have has two small trimmer controls on the back to give manual control over the two spinning mirrors. I would like to be able to switch from full manual control to allow a circuit to feed random resistance to the board at a rate of about one value per quarter or eighth of a second.
This would give a visual output that looked more like a dancing beam. The 'auto' control is very limited in as much as it has one speed control for changing patterns, but it really doesn't change fast anywhere near quickly enough to fool the eye into seeing a dancing beam. I was wondering if something using a 555 timing signal to trigger a random resistance would be possible. The unit's power supply is 6volts DC.
I have excellent soldering skill, a good, if somewhat basic grasp of components. However I lack any circuit design ability
Cheers
