Over in the ACL Mk3 strobe buy thread I started discussion about making a small board to allow the strobe strings to be turned on and off without restarting at the non-random part of the sequence. Here's what I've come up with: You connect 5V power and the strobe string to it, as well as a channel output from the DC controller. This board keeps the strobe string powered up at a low enough voltage to run (and randomise) but not enough to make them visible. When the control input is pulled low by the DC controller, the voltage to the strobes is increased to the full 5V. At this point they are flashing randomly. Because the voltage to the strobe string never drops to zero, they never drop back to the initial part where they're mostly in sync. I'm estimating that I could sell these boards for $10. Postage for 1-10 boards would be an additional $10. Who's interested in these?
