Planck LED Desklamp

  • $10 Planck Rev 2 PCB
  • 5mm high brightness LEDs
  • 300 Ohm resistors
  • Cheap phone stand
Soldered 300 ohm resistors in parallel to the 470 ohm resistors to bring down the effective resistance and increase the current draw of the LEDs.

Planning to add either a PIR or ultrasonic sensor so that it will automatically dim itself.
