Hi,
I have built my relay computer but I encounter a couple of problems:

  • Testing the PC with FF Step and 00 Step all but #5 work. #5 shows a somewhat erratic behaviour. Sometimes on, sometimes off. Changing the relay didn't help, neither did checking and resoldering
  • Changing frequency works but when I switch to 0 the computer always runs at full speed, irrespective of the potentiometer setting. The potentiometer works and delivers between 0 and 5 V.
    Any suggestions would be much appreciated!
    Thanks and best
    Marcus
