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.
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...
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!
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...
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...
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!
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?
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...
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...
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?
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!!!
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...
