Attached you can find my Eagle design of the through hole version.
I just made few changes to the Jay_Diddy_B Design of R.Hirst Design (I left all the names on the silkscreen
).
The idea was to have a super easy layout that can be toner transferred and also
built on a veroboard, since all the holes are on a 100mil grid as the traces.I have't build it as I ended up building the M12864 DIY Kit instead (
http://www.banggood.com/it/DIY-M12864-Graphics-Version-Transistor-Tester-Kit-LCR-ESR-PWM-p-986954.html), but please let me know if you will build it (post pictures...) and if you have any suggestions.
The attached PDF is mirrored to be toner transferred.
Do not scale it and verify the print dimension against the measurement (70*43mm)
Can someone explain me why you prefer to build this analog version instead of the microcontroller one?
That kit came with a nice PCB, the micro already programmed (if this is your issue), a case is available, it can measure capacitance, ESR with 0.01ohm resolution, it can test also BJTs, MOS… and you can find a great support in this tread:

Edit: To answer my question, reading Jay_Diddy_B early posts: "In my design, I wanted to see if I could do something useful with a few transistors"
Well you actually did it great
and thank you for sharing it.
Edit:Do not use files with version below 1.3. There was a mistake in the routing.
