Mounting the electronics contains a few steps. The pictures cover them all:
  • Tracing the circuit using 3M copper tape
  • Choosing a "plus-rail" and soldering the leds accordingly.
  • Testing the leds on a lab power supply and determining the total current through the circuit.
    (In one particular case, two different colors were wanted, which made the circuit a bit more complex: two circuits with different currents, from one power brick :-))
  • Determining the voltage of a discarded power brick and finding out the needed extra resistors to get the right current
  • Mounting the power brick and a finding a way to lock up the incoming cord
