There is an adjustable DC to DC buck boost power supply with a WIFI on ebay for about £25, for details see: https://www.ebay.co.uk/itm/284318838358?hash=item4232b92e56:...

Its has a built in display for voltage, current and power and WIFI. The WIFI enables control of the voltage and current and display of various parameters on a smart phone or PC. The parameters can be graphed (smart phone app only) and saved on the smart phone or PC.

Below is a snip of the pc display:

The wifi interface is definately a twist i haven't ever seen yet on these kind of chinese modules.
I'm soon going to swap my desktop's PSU with something of less dubious origin, so i might couple it with this module xD
My lab is still missing a variable power supply even though i work often with electronics.

If i remember correctly there was a pretty common "variable supply board" that needed a 24v input, and that was kind of a bummber since the only PSUs i could find with the right wattage were LED power supplies (sometimes not of very good quality).
Desktop power supplies are much more common on the used market, and can be found for 5 euros here.

A serial connection would have been better than wifi, for data logging and stuff, but i'm not very sure i'd trust the chinese electronics to not fry my motherboard in case of an accident xD

Ubya: Its the first time I have seen it too. I also would prefer a usb or serial interface, why add to what I call civilization's background radiation spectrum (CBRS). Not that I would mind us being visited by friendly ETs.

On a some what related subject, I will soon be implanted with a cardiac monitor that has a blue tooth interface activated by a magnet. My doctor will be able to phone it via my smart phone to down load data, so perhaps my designation should be changed to 48 of XXX. I will be part Borg LOL.

I have now really joined the Cyborg team.

My Cyborg implant (a cardiac loop monitor) was implanted yesterday with what looked like a larger version of the device used to chip dogs and cats. It was a little bit painful as it was inserted in to my left pectoral muscle despite the local anesthetic. I have been give a card to show security if I have to go through a metal detector.

The area is a bit tend now and painful if I lift anything heavy (26kg dog in and out of a car, she has spinal problems so here rear legs are weak) or stretch to reach something. Hopefully they will be able to diagnose whats wrong with my heart and then fix it.

oh i've never heard of it before, i just have a pacemaker.
i've seen some pics online, it is small, but still, not THAT small, no shit your pec is tender!

(when they have figured it out, asks them to keep it, my plan is to frame all my pacemakers so in a few decades i'll have a nice pacemaker collection hahahha)

ps sorry if the topi is derailing from the original post
