• The Airport Express ready to converted from 110/220 volts to 5 volts. Mark drill position
  • Mark depth: 3 mm and be careful the tape does not move while drilling
  • Large hole - 3 mm deep - marked by tape
  • Drill horizontally to whe weight of the machine does not provoke an accident
  • Unplug with tweezers
  • Pull out the plug to the wifi board
  • Plug removed with tiny screwdriver
  • Check that it works: Black to ground, orange to 3.3 volt and red to 5 volts
  • Disassemble power plug. Some force required.
  • This is hard. Push a thin thread through with screwdriver. Pull a thicker thread back and use it to pull 3 new wires through. Expect strings to break!
  • "Sheet Bend" used to do the pulling
  • Success! Wires pulled through ready for soldering, isolation and being pushed back inside and covered by a 10 mm plastic plug.
  • The 9.5 to 11 mm plastic plug for closing the hole
  • Parts for the new power supply. Notice the plug which will cover the hole when the wires have been cut, solderd, isolated and stuffed inside the shell.
  • Row 1(closest): Ground, Row 2: 3.3 volts, Row 3: 5 volts, Row 4: 5 volts before fuse
  • Not much space. The inside of the plug has been drilled and cut out.
  • Assemble the parts also used in the hacksaw version of this repair, pack inside the hollowed out plug and close with a hot glue gun. This is easy to disassemble if needed
  • The 5 volts power plug connected. The 3.3 volt converter gets a bit of fresh air so it can get rid of its heat
  • Music!
