We got it up and running again, yesterday. 🙂
the issue was that it burned out the Raspberry!!
still noreal idea why, but my teory is that it was due to the core of the soleonoid being out.
my elektronics guru says that, the inductans on the soleonoids rise x3 wen the core is in (activated) thus it uses way more power without the coil in!
dont know if that makes sence to you guys, it is beond my mere skills.
but we cut the new pi´s power pins, and run seperate power to it now, just to be shure.
