Ta daah!
Here it is with the obligatory el84 first measurement
Now I have to figure out the instructions…..
Dragged daughter away from her chemistry revision to dutifully take two snapshots, bless.
Duct tape inside holding laptop smps still is aaahmmm a 'semi permanent' measure…..

Hello from Japan. My uTracer3+ has just started operation. I picked up a 7C5 as the first DUT. Thank you for offering such an interesting kit!

Resurrecting an old thread. I'm investigating the possibility of building one of these things for myself.
In the course of my research I've found that some builders have built their own heater supply for greater accuracy, eschewing the 'pulse' supply that the uTracer has. As far as I can see it seems to be accurate enough, given that heater voltage can sometimes vary that much with mains supply variations anyway. I'd rather keep the build as straightforward as possible.
Did anyone here bother with an off board heater supply or did you just use the uTracer one? Oh and does it go down to 2.5V for 2A3 testing?
Thanks.

Oh wow is me. I was all set to buy the uTracer 6 kit and the up to 100v positive grid board. But the email from Ronalds wife suggests you make sure you can download the gui before you pay. Well our laptop is horendous probably full of junk. It failed to run the gui version 3/11 you must start with. I looked at the helps and its all computerlease that I dont understand whatsoever. So on my ipad I googled for other available gui’s and those are computerlease in a different language or languages that is apple and linux, everyone clearly has problems with the gui in what appears to be three source languages, appple linux and microsoft. So I thought, time I bought a better lapton. Spent £300 on a dell used lapton on windows 11 with a solid state hard drive running in 86. Guess what? It cant figure out the gui either. All this is just to get the version 3 gui you need files from before you load the generation of gui you need.
So far Im thinking? Sack it off .

Any clue why it doesn't run? Most likely a missing dll I would guess. Does it install? If it does, maybe try running a dependency walker to see what is missing.
