Notes

- Some brown oily substance leaked through the bottom part of the device.
  It soaked through the battery compartment, the buttons and some vias
  of the white part of the PCB.
    -> The solder mask broke off from some traces while cleaning the
       substance off of the PCB.
    -> It is still occupying some of the vias.
    -> Diode D2 broke off while trying to clean it. Ripped off the lower
       pad as well. It lost one of its legs, so it wasn't possible to
       solder it back on. I measured the drop off from the original: 0.564V
       Replaced it with 0.58V.
- Only works with DC adapter, not with batteries:
    -> TODO: investigate
- A&B buttons don't work:
    -> TODO: investigate
