I'd be interested in one of these. I want to do a lot of testing on new lighting options

Sorry, I've been swamped with work and travel. I'm ordering the parts I need though. I ran out from the last batch.

I should have a batch of 5 or six done at the end of this month.

I got tired of getting allergies and tearing out carpeting at the moment so I'm preoccupied.

Outstanding! I love seeing DIY projects like this. Have you considered doing an open-source license of some sort for this project? Its great that you guys are doing this for non-profit but it would be good to see you gentleman get some sort of extended recognition for all your work. I'll be keeping an eye on this as I want one myself!

I saw how long ago this whole thing started and at first I had lost hope that I might be able to get my hands on one, but it looks like I might get a chance!

1. Calibrate against a par meter: best
2. Calibrate against known reading to a lighting fixture. Some manufacturer provide this, and there's a thread providing some par numbers: ok.
3. Set the resistance to 27k: not so good but it's something.

Kudos to you for this undertaking! Considering how expensive PAR meters can be, this is a nice cost savings!
