A faulty UVA blacklight lamp from a UK based seller with uninspiring customer service.

This took a very long time to reverse engineer. It has a lot of discrete components, and fortuitously no microcontroller. That means it can be made to work without a need for a serial d...

I'd say this was definitely not a successful venture.
Fortunately I decided to put a towel down to catch the inevitable mess when it went wrong.
I've been using this as my main phone for 6 weeks now, so I feel I can make an accurate review of it. The good news is that so far it's not given any issues at all.

This is the most ludicrously complicated fake power saving plug I've come across.
It's literally switching a 1uF capacitor on and off with microcontroller based circuitry.
