Here are some pictures of mUnits prototype development process. I have no good camera at the moment so the pictures are a bit unfocused. I’ll make a new set with a good camera as soon as I get one.
The nerves: the serial-in-parallel-out SIPO mUnit to convert serial signals to 8×8 diode matrix signal. One chip can drive up to 64 leds, led lasers etc. to provide visual feedback or send distant control signals to another mUnits. SIPO mUnits can be easily connected in serial to control up to a whole gigantic led display.
I found the Howard Goodall’s series on music fundamentals to be very inspiring.
