Need An Oscillator For Your Rally Clock?

Turns out plating was harder than expected given it was an alloy type of box. But it looks great now (even with the pinkish hue in it).

Nice work Gav, I still have some extra oscillator circuits if anyone is interested.

 

Not sure if Ron has reached out to you yet, but is there anyway you could implement some kind of variable resistor into your circuit so that fine adjustments can be made to speed up or slow down a clock?

 

The Oscillator in the photo is actually using Greg's and (Monkey Man) Eric's board at the moment because their's has an adjustment feature that allows fine tuning.

 

It's great to have multiple options, would be even better if both had an adjustable pot on them.

We can no problem.

 

If you run a clock with the board and tell me how far out it is over 12 hours or whatever period you pick, happy to reprogram the board to suit free of charge.

Just saw another box on YAJ!

Z432 S30Z S31Z 3 hands for watches with stopwatch Solid Oscillator High-tech alternative to genuine tuning fork oscillator
Solid Oscillator for Watches with 3-Hand Stopwatch For watches with
two newly developed control knobs.
Both the front part of the watch and the middle type of the mid-term type and the band-fixing type are OK.
Z432/S30Z/S31Z Three-handed watch oscillator with stopwatch The oscillator of
 this watch 50 years ago is a mechanical tuning fork , so it is safe to break it.
If the oscillator breaks, the clock may not work, or even if it runs, it may be delayed by more than 10 minutes a day.
This is a solid oscillator that uses modern parts to substitute functions.
The coupler is on.
- Since there is no dial tone that Boone indoor sound do not mind
a small burden to the so-power consumption is low battery
when the battery re-connection - Since start-up of the force is strong, watch immediately start moving
worry about, the future of failure There are advantages such as few.

The clock accuracy is not so meaningful with this type of clock, but
the error with a clock on hand is 24 seconds a day for 5 seconds and 1 month for 150 seconds (two and a half minutes).
