Two things:

  1. I have a suspicion that these flipdots would look pretty good under UV lighting. Maybe we should have provision for driving multiple independent channels of LED so that I can fit a combined white and UV strip and pick a colour.

  2. Is the stock Hanover LED strip driven at 18V or 24V? 24V is a standard voltage for non-addressable LED strip, so if we retrofit strip it's going to be under-driven at 18V. Some of the LEDs in our signs are looking a bit crap and could do with replacement, so this doesn't solely affect my UV plans. We should check the voltage of the stock Hanover strip, and if it's 18V we should check how well 24V strip performs at that voltage.

The plot thickens, I've just checked the LED voltage in our smallest flipdot and it's running at 16V...

As per discussion on Slack - 16V is a pain - probably going to ignore the LED strips on the first revision. Why would they do this...?!
