Further to my recent escapade with a LG backlight I played around with a LED strip tester circuit I found on the internet, works from 6V up to at least 12V, it has current limiting and a 3V DC out as well as the HV. Works a treat, I designed it for 'through hole' standard components on a 1.6 x 2.6" pcb. Planning of adding a El' Cheapo' LCD dual volt ammeter and running it from rechargeable.
Lol, the darn thing I thought wasn't working until I grabbed the output terminal... this was on a 6V supply, a connection to the LED strip came off - I soon let go of the 175 V lead!
I'll be happy to share the layout and tracking ready for printing if any one is interested. This ought save a lot of hassle with tripping tellies.
