Just built the motor drive for the SP09 and it working, but want to confirm which jumper pins are for speed and direction, I know it’s the top four, but which three are speed and which is for direction
And now I seen the video of the SP11, and the drive is going in that instead 🥺
Great clock, haloween offers too much to choose from.
Mounted 30 RPM gear motor in base with timer to operate for 1 minute every 12 hours. Two minutes a day = 60 minutes a month = 12 hours a year, pretty effecient. Motor should last years.
Gear motor is pretty loud but not as loud as balls being moved around which is very noisy.
Is there an Android app to help tune the timing of these clocks? There seem to be two apps that come up on Google Play but neither seem to work very well. The two I keep seeing are 'ClockMate: Clockmaker Toolkit' and 'Watch Accuracy Meter' but neither seem to work properly for me. Is there a different app that people have found to work?
I use an app called "Clock Tuner". It is no longer available in Google Play Store, but supposedly can be found on third party repositories. I recall having to pay a few dollars after a short trial period.
Hi Steve, I've been running the crazy clock for about a year and but now although the second hand works fine, the minute and hour hands don't change. Could you suggest where the potential problem is likely?
Thanks - Jonathan
There are a few different crazy gear clocks. If it has a second hand, you must be talking about one of the desk clocks.
Here are a few ideas. Check every gear for end shake, especially the central arbor and the friction clutch arbor. Look from the side to see if any gears have warped and are interfering with other gears. Check the set screws on the friction clutch. Follow the gears from the second hand to the minute hand to see if you can identify the first gear that is not moving.
The algorithm evolved since the earliest clocks. The jumper for direction was re-purposed to select debug modes. I use these to test the boards on my Etsy shop. Reversing the motor can be accomplished by rotating the 4 pin connector.
Here are the modes in the latest algorithm:
Motor speed settings (subject to change)
0: 00000 1.000 RPM reserved
1: 00001 4.630 RPM SP10 with 200 step motors
2: 00010 4.630 RPM SP10 with 400 step motors
3: 00011 3.600 RPM SP6 with 200 step motors
4: 00100 4.667 RPM SP9 with 200 step motors
5: 00101 6.944 RPM SP11 with 200 step motors
6: 00110 6.944 RPM SP11 with 400 step motors
7: 00111 20.00 RPM fast debug mode
Debug routines
8: 01000 LED off no test running
9: 01001 LED on simple hardware test
10: 01010 LED on simple hardware test
11: 01011 Delay test LED will blink at 1Hz (0.5s on, 0.5s off)
12: 01100 LED on simple hardware test
13: 01101 RTC test LED should blink at 0.5Hz if RTC is working
14: 01110 Rotate CW Rotate motor one direction at medium speed
15: 01111 Rotate CCW Rotate motor in opposite direction at high speed
