There is a description of a magnet actuator at Andreas Peter's site:
http://www.inchlab.com/ (see Elect.Actuator)
But two modifications IMHO are needed to this design :
- Use heavier duty diodes than 1N4148 indicated in Andreas shematics. 1N4148
is rated 20mA and is probably fried by now... I'd use cheap 1N400x (4001 to
4007) 1000 mA diodes for that.
- use another 1N400x connected in series to prevent reverse connection.

| (...) Hi Philippe, you're right, but you don't need this flyback diode, as Philip Taylor mentioned here : (URL) you don't need a flyback diode, you also don't a diode in series. Rainer P.S.: I had the same ideas than you mentioned above ;-) (24 years ago, 19-Apr-01, to lugnet.robotics)
