ThanX for the advise, for the divergence - I thought it's single-mode....
With "don't know what to do" I mean that with 660nm's I heal, with 405nm I expose PCB, with 638 I .. um ... probably have fun :) I think these are sold as 500mW rather than 1W.
So far his things work - I've tested the BDR209 diodes he sent (sbd allowed me to win 'em), they're reportedly dismantled from BDR209s. So far they arrive in working condition (I have several yet to come). I won also a Mitusibishi ML501P73, which looks brand new (though I don't know what to do...
The emissivity can be software tuned, but it is required to be at least 0.50. With 0.1 we'd get prevalent noise, especially for low temperature differences.
Status: the #1 spray is ordered, because I found it easily obtainable and with thinner layer. If needed, 2 layers of it won't hurt.
I...
I didn't take of this paint when I had the opportunity, so the possible candidates are:
1. Heat resistant paint 650°C - Auto-K by Peter Kwasny GmbH - German paint
Pros: forms thin layer - 7um; heat resistant; Obtainable - I can get it for ~ 8 USD;
Cons: no data for thermal emissivity; doesn't...
Good idea. Now I look for enamel with good thermal emissivity.
The sensor works well against my hands (the human body has high emissivity). Also an enameled pan in my kitchen was measured with realistic result.
It seems that the sensors come from the factory calibrated with a perfect black...
Update:
I've succeeded in programming the MCU to work with the sensor so far.
I've hooked a LCD display to print the temperatures onto it.
It's not sensitive to visible light.
But other problems have risen:
The object temperature measured depends on the object's emissivity. (Damn).
This...
You're right - only for a while.
I'm afraid that we may end up in something worse than the Cold War.
Back then, we were quite strongly afraid that the president Ronald Reagan will destroy the world in compliance with the USA's s fix idea for preemptive nuclear strike against Russia. (Beware...
I think it got canceled due to economical problems. The television decided that there were fewer people who watch it, so . . .
But AFAIK, the people who watched it were of great quality ;-)
It mixed Sci-Fi with drama. Many of the characters had their personal dramas and all of them had other...
@Exerd: "So the intensity at the laser die face always sets the intensity maximum which will never be exceeded at the target."
I don't feel it so true. The people use 40W lasers to cut metal. These would destroy themselves if the energy density at the mirror was greater than at the spot...
@LSRFAQ: Thanks for the NFO on the problems with the sodium quantum levels.
Wow ! That's smuggling :-) I didn't even know about this CuBR technology of our ... who - instutute, factory ? There were factories for non-standard equipment also.
Unfortunately many technological caps we had are now...
First: Happy New Year !
The things are moving albeit slowly: My sensor arrived today :san:. So the next week I'm going to "reserve" some time to play with it with the MCU I have at home.
I'm sure that arduino would help me to do it quickly, but i'm fan of doing some things myself like USB device...
Yes, SG1 was my favorite also. But I've found interesting even SG Universe. They also had very realistic problems there - almost everything on the space ship was malfunctioning :-)
