I just got a SE in last night and I ordered a replay knocker from Planetary and a wire harness from P1nhead ahead of time, which I've already soldered together.
It was only today that I found information about a diode needed on a coil of this type to protect the board from power spikes. In reading through this thread the only mention I can find is that there is no diode on this knocker but people are using it anyway without issues?
I'm not eager to risk this rather pricey toy. Can anyone out there confirm why it is safe to use without a diode, or if it really is important for safety what I should be ordering?
Thanks, and happy to be a sheriff in training!
