The prototype look like this (Pics). I call it Mutualism or Parasitism circuits
Bacillary, I will use all my junks to build one.
Yes,LED tester parasite in Samsung 55' LED TV power supply.
An adjustable DC voltage 0-340v ,LED screen tester, with PFC ,IGBT, with DC 0-600v voltage and 0-10A DC current meter....................(i ordered this one) DC 0-600V 10A Voltmeter Ammeter LCD Panel Amp Digital Volt Gauge meter 12V/24V [ D85-3051]
PFC: IC used this one
{Self-talk} Samsung power board BN44-00499A ....%$#%#^%#^....... because I have more than 10 of them.... %$@#%$@^^ ..... Ebay about $5.69.....^$&$&^$.........Yes, I don't know how they pay the shipping ....... ^%#^%....... ^%#^%#^.......
