i made a clock
its simple but it works
Chips must be connected to inputs and outputs. If you use NOT chip as source power without connecting to inputs, your chip won't work. Check your schemes for this mistakes and make sure it works.
If you need to create clock, which always generates signals, make OR chip, then create clock scheme with NAND chip, connect clock's input to OR output, then connect straight and inverted main input signals to inputs of OR gate. Then, there is no matter, what signal you use on main input. Main output will always clock.
