Doe anyone have a location to download the conversion chart pdf, that is used to convert the temp readings taken with a dohicky into watts?
i'm going to be measuring my hackspaces laser tomorrow with the one they have there, but i need the chart to make sense of the readings i get.

Cheers,
I contacted Russ on his youtube page, and was told the production Dohicky's were altered to correlate the temperature to watts,
So for 0-80 watt lasers, beam on for 20.5 seconds, then double the reading to get watt's output power.
I'll be having fun today trying to time the laser to be on for 20.5 seconds, as the rubbish LAOS controller we have, speed is 0 - 100%, and that 100% speed is unknown.. very slow is all i know.
Decent controllers do mm/s, but not this thing we have
