Here's my new DIY setup, I'm still working on the case, but the component tester is working well and it's good to be able to enable all features of the M firmware and still only reach 78% full using a 644p.  :clap:

The display is a 2.4" ILI9341 and is connected with dupont leads so I can experiment with others displays, the ST7735 also works well, but not
as nice as the ILI9341.

The board is based on the open source hardware design, I have just moved some of the device footprints a bit closer to fit on a 100mmx80mm board. also added an extra pin for backlight, the board supports the 30v zener test but I have not yet added the components for that part.

There are a couple of typos on the silk screen labelling, I wanted to fully label the board so it could be build without referrring to a diagram.

Is the board your own design?

Quick and dirty with outlet box I happened to have on hand. Does the job. Looking at some the the postings, I think I will upgrade.

For Reference:  Our very own BillyO on his Uni-Byte Youtube channel just recently posted his 3 MODs of his T7 Transistor Tester

1) Increase battery capacity
2) Improve connectivity
3) Make it more stable on the bench

Improved my DIY setup from above, attached the gerber files and a preview of the layout if anyone cares to have a go at building it.  ;)

That's super nice alex_D!
Would you consider making it compatible with relay protection also?
I've seen it mentioned by many that the SRV05 protection diodes are pretty sensitive and often short when they protect from a charged capacitor?
Anyway great work!
