Furthermore

  • we will need an enclosure for the 230V part, it has huge screw terminals that will be at high voltage when in operation.
  • when(if) the thing works we may also want a case for the other parts to keep it organised.
  • we will also need a flat piece of metal to rest the subject on during soldering.
