90p .. Let's test it on some LED strips

[@peterhancox6962]

Thankyou i used to do electronics for 30 years but i have been watching your channel and i finally fixed a flat screen lcd after my stroke

[@allenfleckney5969]

@@peterhancox6962 I hope you have made a full recovery. Good work on the TV repair.

I built my own 30v/5A power supply many years ago with multiturn pots and meters for voltage and current, it still works and has more than earned it's cost. Back in the 70's there was no internet to buy cheap gear from.

[@irishguy200007]

I got one of those last year, love it.

Looks a nice handy bit of kit thanks Allen I’m going to get one or two, as there handy if power supplies or main boards are missing voltages 😊

[@irishguy200007]

It would be nice if it came with a few presets. That would be my request.

[@jasejj]

I would strongly suggest reducing the supplied current right down. An LED will consume any current you give it (but only the forwarding voltage), and as there's no current limit you can burn these out quite quickly doing that. Current, rather than voltage kills diodes. 30v through a single LED is fine if you limit the current down to say 10mA.

Just had a look and it's now between 10 and 15 euros (didn't check shipping costs - some may be eligible for free shipping, depending on minimum order value).

[@f.k.burnham8491]

You got a great price on those units. $14.95 and up on Amazon here in the U.S. and close to the same on Temu

I used a 30v laptop PSU and an old school variable regulator with a pot on it. 4 component regulator, diode, resistor, pot, capacitor

SOUND REALLY REALLY LOW..... sorry brother 👍

Iam so scared of electricity but i think i can replace my backlights on my Samsung tv.

[@irishguy200007]
