• Day 2, flipper...

  Somebody recently left a lot of old electronics at our hackerspaces, most would call it trash. And there were 2 completely fine beefy toroidal transformer. 230V to two times 12V. 

  So the 24V AC for the flipper coils issue was solved for free, which is pretty cool.

• Day 1: Power supply

  I wanted to check the flippers today, but unfortunately the transformer died as I found out. 

  But I learned (again probably) that they run on 24V AC.

  All the other coils run on 24V DC.

  Then there ar parts which run on 110V AC.

  And lamps and the whole logic runs on 6V AC.

  And since I don't live in square inch per freedom eagle country I have 230V AC.

  Oh, boy.

  Since 110V is mainly used for the score motor (great piece of technology, but unfortunately I don't think I'm ready to rebuild the whole thing from scratch) so I can leave that aside for the moment.

  Since I will replace the lamps with LEDs anyway the whole 6V DC isn't needed too.

  So for now I need.

  * Something between 20 and 24 V DC for the coils.

  * 5V DC for the IO

  * The weird 24V AC for the flippers. Unless someone can point me to other coils.
