Hello everyone, I am new here and have come seeking help with what I thought would be a simple project.
I want to add a power indicator LED to my Hakko FX888 soldering station. The problem I am encountering is that it seems that no matter where I attempt to pull power from on the circuit board, it interferes with the operation of the circuit.
Has anyone attempted this mod successfully and if so, can you give me some guidance on how you did it?
