Right, and I guess the Huey is still the low cost instrument to beat.
It's certainly what I advise people who ask to buy.

I guess if someone was to manufacture the devices in small quantity
they should just calibrate them at manufacture time with something
like a ColorMunki. I assumed you wanted to post the PCB and BOM online
and let people make their own colorimeter, open source style.

Right. It sounds like you could commercialize this and make a bit of
pocket money, on the assumption you can undercut the huey by a
significant enough margin for production volumes < 1000 or so. That's
the tricky bit.
