Sorry :) I know. That is right, and that is the problem :) Are there no canche to use an arduino and a diy tec sensor?? I know that is not a exact measure but i want to test my goggles and i think for that it is good enough.

i know this is an old post but it is very interesting and exactly that what i search. Is there anywhere a detailed instruction and the sketch for the arduino? Or elsewhere a newer arduino LPM Project?

there are other opinions? What is better for engraving 300mW 405nm oder 445nm? 445nm is cheaper, so i can get a 500mW laser. But what is better, the 300mW 405nm oder the 500mw 445nm ??

i want to build a small laser engraving machine. but which is the best spectrum for engraving? 405 or 445nm ? i want to use 200-300mW. if possible, i want to cut paper and foil to make my own masks for airbrushing. thanks for help.

I want do build a laser engraver with a 405nm laser. At first i do experiment with 100mW. Later if i have enough experience i wil use a 300-500mW laser. Now i am looking for a cheap but good laser protection goggle. I have found this one: Laserschutzbrille 200 - 540 ***mit Etui*** | eBay Anyone...

is there a list from dvd writers with good and strong laser diodes? or can someone give me the name of dvd writers with good and strong laser diodes? i think a list would also be interesting for other people. many thanks! XF
