which one ? I've been looking for something like battery powered power supply that could double as battery/phone charger (which could probably be easily hacked in into existing design if code was available)

sorry - not battery powered... I didn't realise this was dave's intention for this product.


The fully DIY friendly option for a bench supply is this guy:

all firmware and hardware is open source.

Ah yes I saw that one. I looked, said "no knob, no service" and ignored it. The last thing I want from my bench supply is some wonky touchscreen

Just make sure that the power supplies share common ground / 0V and not that low side current measurement sh*t.

As long as I remember, he uses only one channel and it doesn't have low side current measurement.

It is good to have different opinions, but for me the TFT screen is a big plus!  :-+

It makes it modern and gives a lot of options unlike traditional buttons. It inspired me to do my own power supply using a TFT too, but Dave design inspired me about the battery powered feature. I still didn't manage to make a PCB for the prototype.

make sure to have dual color backlight. if a fault condition occurs i want the display backlight color to switch to red. ( and blink if possible  like 50% on , 100% on , not full on / off)
Also  think about colorblind people.  make sure there is a huge difference between red and green ! too many dual color led's are indiscernable for colorblind people.
