Hi Bert, Thanks for posting that project. What a wonderful combination of electronic and mechanical timing, of design and measurement, of hardware and software, of PICs and Python.
One side experiment that would be interesting is to collect a couple of days of data using a fixed drive and then compare that with the same number of days using your adaptive FLL drive. The resulting phase or rate or ADEV plots would be amazing. /tvb ----- Original Message ----- From: "Bert, VE2ZAZ" <ve2...@yahoo.ca> To: <time-nuts@febo.com> Sent: Monday, June 08, 2015 10:11 AM Subject: [time-nuts] Electronically Disciplined Mechanical Pendulum > Greetings, > > > I just want to let those who are curious about disciplining a mechanical > pendulum that I have pretty much wrapped up playing with a 1m-long pendulum, > which I control with PIC micro firmware and try to mainain at a constant > temperature.
