7 months agoHe commented on monomuino: Arduino-based monome compatibledr unsped: First of all, this version isn't using any digital pots at all; it's just connected to the blue channels in an all-or-none fashion.
On the RGB version higher pulsed current would partially solve the brightness problem, but not completely. Part of the problem is that the digital pots have resistance even when set to zero. That limits the maximum current I can get at 5V, so I couldn't pulse much higher without using an external power supply.
I have several of the TLC5940 chips and they're great! That's what I'm planning on using in version 2, if I ever get around to making it. -
