Epicyclic Gear Clock

Well Im still seeing how long different battery setups last. But the 2 different boards I had made up 1. a Regular Pendulum Driver (very accurate) you can control both the Pulse and Gain and can run with 2, 4, 6 AA batteries. But your mileage will vary... the more batteries the longer it will run of course. 2. a Regulated Pendulum Driver that will work perfectly with the SP7 clock now and is less then 3ppm with the compensated oscillator. That board requires 6V power since it has a programmed MCU that requires 3.3v to run. That was why I had asked you if you still had the rectangular box for SP7 as if you want to use either of these boards with batteries you will have to use a box and not the X shape base that you have now. But you CAN run the current base with the regulated pendulum driver, but can be only powered by USB. And modifications to the current base need to be done as well. I can provide these STL files to anyone and I will be making kits needed for which ever way to want to run your clock. As for what I created I wanted it both ways either battery or USB power. So that had to be in a rectangular box and top to fit everything inside. The coil is hidden in the top too so you don't see it. There is a toggle switch to switch between battery or USB power. The clock also requires rare earth magnets too. As they are much stronger for the coil pulse. I am still using the AliExpress Coil (Black Version) that works much better then the (White Version) I found the white coil is unreliable because it is not a regular wound coil. It is like a bifilar coil (two coils that oppose/cancel each other...). which is used with a different driver. They are started and wound to the center post and wound in opposite directions. Hence the magnet needing to be both positive and negative on the same plain. The black coils are one single wound and require a magnet with one positve or negative plain to operate. Also now is a good time to explain why the original setup with the regular pendulum driver from AliExpress or Amazon was soooo fiddly. I spent months figuring out why this wouldn't keep time and after buying a oscilloscope and a EMP meter, I finally found out what was happening. Electromagnet coils put out a Electromagnet pulse. After measuring the circumference of the EMP I realized it was going way past the battery. the EMP was causing mini brown outs in the batteries causing the pendulum to swing erratically causing the lose of never keeping time. I could read the brown outs on the oscilloscope. Anyway..... The Epicyclic Gear Clock is now running perfect with just the Regular Pendulum Driver board. and been only off by 1 sec in 6 days now. In running it against an Atomic clock. When you want to start on the SP7 revision I will be glad to send you a few PCB's. Or send them sooner to you if you want to try on your current model. It is running perfect on the SP7 and the Art Deco version of the clock that I did. Here are some photos......

Forgot to add the picture of the regulated pendulum driver board
