The Core16 prototypes are alive and well! Everything is working correctly. Even so, a few tweaks and silk screen corrections were in order before releasing a larger batch for a pre-production build. While the boards are being fabricated, I'm working on creating a robust test fixture to streamline testing. For the other Core64 kits, I've been using this contraption I slapped together. Reliable isn't a great word to use when describing it.

Alas, design and assembly time was short.

This time, I kick started the Core16 test fixture by ordering one of these kits from Amazon:

I know I'm in for some assembly adventure, but it should save some time and provide a good base to work with. This might be my first and last DIY fixture. I've learned a lot from the guys at https://fixturfab.com/ through this video. Still, I'm gonna give the scrappy method a chance and creatively consume some junk drawer inventory. And it's all brought together with some 3D printing, of course. But the results are encouraging so far.

That's the moving plate. Seems good enough to move forward with. Now, on to the probe plate with the VERY IMPORTANT integrated power switch! See video linked above if you want to understand the nuances of test fixture design and why a switch is important.
