I bought the DLP NIRNano EVM about a year ago and haven't really used it much.
In the beginning, I could easily scan with the NIRNano, but recently it popped up with a scan error very often. So I decided to update the firmware, but now it is really rare that the device can actually record a spectrum. I get a scan error almost all the time, and occasionally the lamps turn on (but still get a scan error).
I have it connected via USB to a laptop or a desktop computer.
