The second meeting of the Electronics SIG will take place at the above time. You are welcome to join us.
We would be delighted to hear how you have applied electronics to your layouts, or to learn if there are aspects of electronics that you think would support 009 modelling that we can put the 'hive mind' towards finding some answers. (Note there are separate SIGs specifically for DCC and for Radio Control. The Electronics SIG is for general Elektrickery.)
Many thanks to Iain for setting it up for us. The details are below.

Just in case anyone reads this at the time - I am locked out of the meeting and it is saying the host has another meeting in progress. I'll keep trying for a bit longer.
I expect everyone will have the same problem. We had this regularly for our church's Zoom meetings. We had two meeting IDs set up with the same host and using one of the IDs we often got locked out with the same message, but curiously if we switched to the other ID we were able to connect without any problem.
We did get online - many thanks to Hugh for quickly setting up a 'free' meeting, and Zoom were kind to us allowing over the 40 minutes because we were only three. A report to follow later when I can decipher my scribble.
We had a bit of a technical glitch with Zoom refusing to allow us to join in the meeting set up for us on the Society account. Hugh came to the rescue, setting up a meeting to start straight away using the free version. Zoom were kind to us and with just three of us present (Hugh Norwood, Graeme Dunbar and out latest 'recruit' Sam Thompson) it relaxed the 40 minute limit. Frank Allen sent his apologies.
As Sam had joined us we started off with introductions.
Sam explained he has an interest in controller design and though his work is mostly digital electronics related is keen to dust off his notes and work with analogue electronics.
Hugh showed his animated Discworld model and this fed into a number of discussions on motors and gearboxes. He has installed a Frizinghall Models turntable motorising kit that does the job of rotating the Disc, but is a bit noisy; we discussed possible alternative solutions.
Graeme showed a few model railway electronics books he had, with the books by Roger Amos, though old possibly still being the most useful source of information on traditional DC transistor controller circuits.

We also looked at the Scottpages review of a number of model railway controllers.

We all expressed a general interest in controller design and pondered whether there was work that could be done that might be of use to 009 modellers. Topics such as selecting resistors for low voltage motors and resettable 'Polyfuses' were discussed.
Associated with this is the question of whether there would be any merit in gathering information on combinations of controllers and 009 locomotives to try to establish if there were ones that worked particularly well, or not.
