The PCB has been redesigned - we've decided to use SMD parts which can be placed using a pick-and-place machine and left the LEDs to be assembled by hand. This makes it easy to turn it into a DIY kit which doesn't require a huge amount of soldering - just the LEDs. With this redesign, we've addressed the PWM issue - we can now display the whole color spectrum using generic RGB LEDs.
