    Trying to repair a circuit board for a rolling ball clock

    Just as a followup. I finally managed to replace the electronics with a 1RPM motor. I created and 3D printed some brackets to hold the motor in place. I had to remove all the previous electronics and support posts to install it. Now it is back to functioning as a clock and keeping time.

    Trying to repair a circuit board for a rolling ball clock

    I'm sorry I thought I replied to the DMs but I didn't. The batteries are "C" cells. The clock (powered by the battery only) is at 1.5 volts. It is also 1.5 when I plug in the adapter OR put in the batteries. I purchased a 1 RPM motor (120v) which I intend to attach directly to the arm...

    Trying to repair a circuit board for a rolling ball clock

    I ordered the 1RPM 120v motor and plan to replace it this week. I was really hoping I could get the PCB working correctly but that seems to be unlikely. Thanks for all the assistance getting to this point!

    Trying to repair a circuit board for a rolling ball clock

    The batteries are "C" cell types. The wall wart only has 100 or 300 ma positions. I first tried switching to the 300 ma position but nothing happened. I then switched the voltage to "6" (which it was for years despite being more than 6 volts which I never knew before) and suddenly the clock...

    Trying to repair a circuit board for a rolling ball clock

    The voltage coming to the red and black clock input voltage is 1.7 with either the batteries or the wall wart. I attached a battery directly to the clock wires (shown below) The clock is running and if I attach a wall wart also the arm does not rotate at the top of the minute. I tried...

    Trying to repair a circuit board for a rolling ball clock

    I am giving up. I can get a 1 rpm clock motor and make the clock functional rather than trying to troubleshoot with my limited ability and skill set. Thanks for putting up with me!

    Trying to repair a circuit board for a rolling ball clock

    The clock seemed to run fine until about 12:30 am this morning when it stopped rotating again. I removed and replaced the batteries but no arm rotation. I left the batteries out overnight and reinstalled this morning and the clock worked again. Could the caps be causing this issue?

    Trying to repair a circuit board for a rolling ball clock

    I am not a professional solderer (maybe not even good enough to be an amateur) but I gave it a shot. First image is the "before" and the second image the "after" Not sure I improved anything (hopefully didn't make things worse) but at least the clock is working. Currently on batteries where I...

    Trying to repair a circuit board for a rolling ball clock

    I will start that process tomorrow and show a photo of my results.

    Trying to repair a circuit board for a rolling ball clock

    Battery powered just failed after a few hours (about the same as the wall wart.) Clock still working but arm never triggers.

    Trying to repair a circuit board for a rolling ball clock

    I'm sorry but I don't understand where you want me to solder/tack a wire across. I did remove the wall wart and inserted batteries in which case the clock started working again. I can simply allow it to run as long as possible via the batteries and see if it goes several days which might seem...

    Trying to repair a circuit board for a rolling ball clock

    My celebration was premature. The clock is back to no longer rotating the arm at the top of the minute. Are the caps still a potential issue? Should I simply buy some and replace both?

    Trying to repair a circuit board for a rolling ball clock

    My wife located a tiny rubber washer that was a snug fit. Clock back together now and running. I will now wait for a week(?) and see if it continues running. Thank you again!!!

    Trying to repair a circuit board for a rolling ball clock

    My electronic knowledge is minimal. I do have a 100uf 25v and a 1uf 50v caps available from my arduino kit. Just out of curiosity I unscrewed the board from the mount and suddenly the clock started working again. The screws are black metallic and I took a picture of the mounting hole. It...

    Trying to repair a circuit board for a rolling ball clock

    Voltage between the two black wires coming into the board is 6.3 volts. Voltage to the two wires going to the clock is 0.85

    Trying to repair a circuit board for a rolling ball clock

    I was concerned that opening it back up to get exactly where the wire was might cause it to fail again. Unfortunately I was correct. I took pictures of the black wire connection ( I cannot tell if it is positive or negative) then closed the clock back up and powered it up. Now the clock no...

    Trying to repair a circuit board for a rolling ball clock

    I think this puppy is fixed. Over 96 hours of continuous operation (more than 5700 rotations.) Thank you 73's de Edd for leading this "fewl" down a path of repair. It does beg the question of the loose wire. Would that have allowed the clock to run but not the motor?

    Trying to repair a circuit board for a rolling ball clock

    So 48 hours now and still operating or 2880 arm rotations. Maybe fixed?

    Trying to repair a circuit board for a rolling ball clock

    So far it is still running correctly after 22 hours. So potentially the poor wire connection could have been the issue?

    Trying to repair a circuit board for a rolling ball clock

    Tracing the wires led me to a broken black wire coming from the two black power supply lines. I soldered it back to the top of the board (was originally coming in from the bottom) I inserted the batteries and currently the clock is working. Previously it would run for about an hour or two...
