 +I designed a testing board with a SN754410 H-Bridge driver for testing. I can test 4 outputs and 4 inputs per testing board easily with an arduino now. The SN754410 is still in delivery and will get assembled later.

 +My automated long term test is up and running. 1000 test-iterations per bit. Tuned the loading speed of the C (adding 100 Ohms), added diodes (1N4007) and tuned the holding voltage of the relais better by adding 100 Ohms.

 Fixed the "4-Bit Register rev2" board. The board is fully functional but has some drawbacks. You need to scratch away 8 traces on the board and solder 8 short wires on it.  Fixed the "4-Bit Register rev2" board. The board is fully functional but has some drawbacks.
