I'm building my own stop action magnets for a pipe organ.
The actual action is effectively just a rod that will activate a reed switch when in the 'drawn' position, and deactivate in the 'pushed' position. I have that all under control.
The difficult part is that the whole array of...
I feel like I am stuck because don't know how to solve following "simple" solution:
Somehow I have to (each 60 min) activate 12V/2A electromagnet, with 5V input voltage (tipical PC USB (5V/100mA).
5V is powering microcontroller, and with that microcontroller, each 60 min I have to...
I have an electromagnet made from a Microwave oven transformer.
I am only using the coil with the thicker wire.
I've separated the transformer core into the "E" shaped bit and the "keeper" shaped bit and removed the other coil.
When I turn the current off, I would like the attractive...
