  • Electronics is the branch of science and technology which makes use of the controlled motion of electrons through different media and vacuum. The ability to control electron flow is usually applied to information handling or device control.

  • The branch of physics and technology concerned with the design of circuits using transistors and microchips, and with the behavior and movement of electrons in a semiconductor, conductor, vacuum, or gas

  • the branch of physics that deals with the emission and effects of electrons and with the use of electronic devices

  • (electronic) of or relating to electronics; concerned with or using devices that operate on principles governing the behavior of electrons; "electronic devices"

  • Circuits or devices using transistors, microchips, and other components

  • Put right (a damaged relationship or unwelcome situation)

  • the act of putting something in working order again

  • restore by replacing a part or putting together what is torn or broken; "She repaired her TV set"; "Repair my shoes please"

  • a formal way of referring to the condition of something; "the building was in good repair"

  • Make good (such damage) by fixing or repairing it

  • Fix or mend (a thing suffering from damage or a fault)

  • (part) something determined in relation to something that includes it; "he wanted to feel a part of something bigger than himself"; "I read a portion of the manuscript"; "the smaller component is hard to reach"; "the animal constituent of plankton"

  • (of two things) Move away from each other

  • Cause to divide or move apart, leaving a central space

  • the local environment; "he hasn't been seen around these parts in years"

  • Divide to leave a central space

  • (part) separate: go one's own way; move apart; "The friends separated after the party"

USB socket repair on Korg Nanokontrol - wires everywhere.

USB socket repair on Korg Nanokontrol - wires everywhere.

I soldered wires between the pins of the USB socket and the next component in the circuit. Two of the pins are shorted to ground and I connected them to the ground on that CON2 header... maybe some secret serial header for developing the microcontroller software.

The full story (for a twitter friend!):
When the USB socket came off it tore up the solder pads that it was connected to, so I gave up on reconnecting it and let it sit for six months. Later, I had the idea of following the traces back to the next component!

So, the USB socket has 4 pins, Ground, +5V, and two data pins (tx and rx right? (or am I wrong?)). Ground was the easiest, because it could be soldered to any grounded place on the board, I used the ground pin on the CON2 header (you can tell because it connects to the giant green area which connects to the casing of the USB socket.

Following the other three pins' traces leads to three tiny surface mount resistors, so I soldered pickup wires to each one.

By far the hardest part of this was soldering hookup wire to the TINY pins on the USB connector, the pins are very small since they solder straight on the board underneath. I used some tape to help keep the solder joint together and insulate them from each other.

After the pins were connected I tested the nanokontrol and it worked (phew) so I soldered the USB socket back onto the board and then locked everything down with tape. I added some foam inside the case to squish everything together tightly so that it wouldn't break again.

So far--- everything is ok and I've performed about 25 times with the nanokontrol! (I broke it before I had even one performance when it was new......)
