>Please use pin headers and sockets instead, so they slot together onto a motherboard.
I was worried the connections would not be reliable with them. Clamping the wires down with a screw seemed more secure. Perhaps you're right though.
>You don't want to be screwing and unscrewing thousands of connections as you troubleshoot.
I was hoping to keep troubleshooting to minimum by keeping it very modular. Making a module (multiplexer, adder, whatever), testing it, and using the tested module in a bigger box to make a bigger module.
>Do a test and find out. Turn one relay on and off with another relay at like 10Hz for a couple of hours. Have two of these setups, one with a diode and one without. Pretty sure it will be night and day.
A couple of hours? The datasheet says 100000 minimum, I expected the actual durability be much higher?
Anyway, I will do the tests.
>Also what are you using for a display if no semiconductors?
I will print my own seven segment displays with E10 light bulbs in them.
