As I got some nice feedback from the acrylic clock I recently built. I thought I would put up my home designed pendulum clock.  This was created using gearotics and I designed my own escapement using an Arduino and a LED gate.  The pendulum is driven by a motor that provides an impulse ...

That is really cool.

I think that a synchronous motor counts line frequency, so the long term accuracy should be nearly perfect.

Hi, Steve, you are absolutely correct. The motor does use mains frequency and consequently it is very accurate.  I have been running it for three weeks ...

Nicely done CSI, awesome job and thanks do much for sharing.




Thank you, I am really pleased with how it has turned out, looking forward to giving it to my friend later this week.  I have printed a sheet on its construction and calculations so he can see how it was made.  I am now ...

Hi I have finished creating with gearotics a clock for my friend. &nbsp;Designed the ratios using a spreadsheed drew the frame with draftsight, cut the acrylic with my laser cutter. &nbsp;Keeps good time (< 1 minute in three weeks) and will be giving it to my friend in a week. &nbsp;Really enjoyed ...
