MaxiBlink is a 4x6 LED matrix that lights up in seemingly random patterns. It is built without any programmable components and was inspired by the BlinkenHAL, though it is different in internal mode of operation.
Mode of Operation
BlinkenMaxi is based on a 10 bit Maximum Length Sequence shift register with one row or column of the LED matrix connected to each flip-flop. The matrix's rows are connected diagonally to prevent the patterns to be too "rectangular". A 555 oscillator is clocking the shift register chain. The circuit doesn't have a power-on reset, so if all flip-flop stages are set to "0" when powering on, the circuit won't start up and all LEDs will remain dark. In that case, repeatedly applying power helps, it will work eventually ;-).
