The Konica Minolta CS-1000A came in, the seller included an old cal certificate too (the traceability diagram is neat).
Did a quick sanity check with an incandescent torch and it read CCT = 3328K, Duv +0.0003. Good enough for me, the man with only one clock knows exactly what time it is. The measurements are outrageously stable to the point where I think I can easily measure the tint shift as a LED heats up, I shouldn't be surprised as the chromaticity repeatability spec is xy 0.0002.
I like the Nescafe lens cap, the kind seller tried to find something that fit instead of just shipping it out naked hahaha.
Now I can't seem to get serial working with an FTDI USB serial cable, might be time for a teardown soon...
