Show us your $20 Transistor Tester enclosures and mods (note: lots of pics)
bitseeker:
Starting this new thread for everyone to share how they package up their $20 transistor tester (LCR T3, LCR T4, GM320, AY-AT, etc.) or make other physical customizations to the basic kit.
For firmware-related discussion, visit the original thread $20 LCR ESR Transistor checker project.
Here are some examples to get started (click thumbnail for larger image):

Added an ISP connector, banana jacks, a Li-Ion battery which is charged through the DC connector, and replaced the crystal with a 16MHz one.

A 3D-printed case with banana jacks.
upsss:
This was my original tester.
bitseeker:
Thanks, upsss. You can attach larger images. The forum will create the thumbnail for you. I had to do them manually in my original post because I referenced images from the original transistor tester thread rather than reupload.

This post seems to me a very good idea, so I'm going to put the photos of my 3 LCR-T4-H multimeters.
