[ebony +smd seq lite]

Lovely work there Peter. I really need to get some ebony leftovers as well :thumbsup:

[MB9090III]

Looking good Jef :thumbsup:

[Crowbar Module]

Nice find technobreath! I was looking for an up-to-date replacement for the MC3423.

The above circuit will do. But the problem with zeners is they only come in certain values.

So for example a 12.6V zener kicks in if the voltage exceeds 5%.

However the 5.6V zener kicks in after 12%. Which could already be fatal.

Nice one. Expensive enclosure? mine is still kinda homeless :ahappy:

Ah, i have a can of that here. A green mask. But haven't tried it yet.

Looks good. Just make sure you don't connect all the IC to one big heatsink. The metal backside of the 7915 is not GND.

[Some progress.....]

omg, this is looking very promising :sorcerer:

[GM5]

The GM5 v1_1 module. Unfortunately i discovered too late i was using the version 1_1 pcb. The GM5 chip was already sitting on it nicely. Hence the ground pins of the DIN sticking out.
