Of course, this is an incentive for having crystal-controlled dc or ac motors that do not depend on the line frequency.

Or generating your own AC with a much more stable frequency than the power company provides ;)

I like building stuff. At some point, enough is enough. I'll buy a tool, don't need to mine copper and grow semiconductor crystals.


I'm on the waiting list for when these are back in stock.


I know, I'm a hair-shirt, lazy copycat, end user.

How will I live with myself. The shame of non-DIY!

Yep, David,
In my case I'm running a DC motor so I need to adjust to the correct speed. As designed, the motor controller should keep the motor at the right speed, and that is something I'll check over time. :)
