It works, just a pain to do.

Firstly, I 100% like the labels and holes are on the box, it's great. The supplier emailed the instructions and they are suitable for anyone with a basic understanding of assembly.

Wrapping the toroid is a pain, but the actual soldering to the switch was ROYAL PET. Also, it was easy enough to build, I can say it makes a…

  • Box is perforated very easy to install
Cons
  • No power
