betwixt: "higher voltage than you need"
Well that is better than my Falstad simulation (some values must be wrong). As I can do with 24VAC I think I will try with a 24 VAC 240 VAC transformer (ratio 1:10 should give 37VAC minus inefficiency) to start with.
I don't have any power transistors so I...
I have this old black rotary dial phone which I want to connect it to a GSM module and microcontroller.
The bells will ring at 24 VAC but they sound better with 48 VAC (no sound at 6 VAC). Inside the phone there is a schematic telling the bells has 1000 Ω resistance. I calculate that to...
