AlexI did stated with the soldering of the first rev2 board. Now I have to wait on the missing transistor before soldering the other (the LED) side. The coin in the image has a diameter of 16.25mm/0.64''.
I am also not sure yet which LED color I will use. If you have a wish please leave a comment. I do have red, green, yellow, blue and white LEDs.
