Hi Dave
You've done it again!!
Your clocks are not just superb design and craftmanship but works of art as well.
Eliminating the problem of weights makes for much more design freedom.
A couple of questions.
Is the magnetic pulse triggered by proximity or a timer?
If by timer, is it adjustable for different pendulum durations?
How long should the battery last?

Well thank you very much, I do try my best you know!
I have been in a bit of a quandary about whether to build an electrically powered clock, but I wanted to offer a small, no problem stand anywhere clock. I could have gone for spring powered but to get it halfway accurate it would have become more complicated than I wanted.
The drive unit has a coil, and when the pendulum magnet passes over it, it produces a small electric charge, causing a transistor to fully conduct, powering the coil and repulsing the pendulum magnet.
The drive unit impulses the pendulum, but the timing of the clock is still regulated by the pendulum.
So at the end of the day it is still very much a mechanical clock.
I would expect the battery to last at least a year, but as my first Quintus has only been running for 2 months please ask me again in 10 months.

Re: Wooden gear clocks
Dave, you are a genius!!
I have just seen Sextus.
Ignoring a couple of very high priced bespoke "art" clocks, this is most beautiful wooden clock I have seen.
Mr Harrison would be impressed.
Forget my own designs, I can't wait for the kit and plans to be available.
What is the run time and how heavy is the drop weight?
It looks very efficient.
How is the battery going in Quintus?
In the meantime, have you seen this?
I'm surprised it only took him six months.
Regards
Greg

Re: Wooden gear clocks
Dear Greg
The Sextus was originally going to be a totally different clock. I always start a new clock by building the escapement, and if there is one thing I have learned, it is never to flog a clock. If it does not work from word go, it is just not worth the effort .
So I thought “let’s just see if a H1 is possible in wood”, and the escapement worked first time, and after a few tweaks, I got it bang on.
So, as to run time, at normal hanging height it runs for 2 and a half days, with a weight of 4.1 Kgs. Which are really good specs when you consider that it has 2 pendulums, so twice the friction, twice the drag etc. The H1 had to be wound each day!
Well the 10 months are not quite up, but the Quintus is still ticking away on the first battery.
I could not open the video as it infringes some German music copyright.
As to being a Genius, I told the wife what you had written, her response was to put a snow shovel in my hand with the comment that I could “geniusly” remove the snow from our yard
Yours Dave

Re: Wooden gear clocks
Hi Dave
Wives just don't recognise genius in their husbands.
We don't get snow here but with plenty of sun and rain at present I need to mow our large lawn every five days or so.
My computer savvy son has reloaded the video and says this should work.
The music suggests that the maker could be an Aussie.
The fact that months are in English and days in Polish or something is a bit odd.

Hello,
Are the clocks a downloadable project?
Thank you,
