  I have also little soldering experience, but I managed to create custom extension cables:
  
  First: open the cover with a small screw driver:
  [![enter image description here](https://i.sstatic.net/qYpX0.jpg)](https://i.sstatic.net/qYpX0.jpg)
  
  Remove the PCB by lifting the small notch to open the light block
  [![enter image description here](https://i.sstatic.net/QYlpn.jpg)](https://i.sstatic.net/QYlpn.jpg)
  
  Then you drill a small hole into the opposite side of the metal plates, insert a small 2-wire cable (~0,25mm) and solder it to the PCB.
  
  The outer ring is Vin and the inner ring is GND.
  
  Then put it together and have fun.
