Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

NS -- I got some new 1500 degree paint. Haven't tried it yet but the 1200 degree paint went to smoke in about 2 seconds. I'm getting closer to controlling my PWM !!

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

good deal my meter will be here friday so Im trying to set somthing up maybe I will just try my lower powered lasers first, I also have a new znse lens coming 5/8" with 2"fol I hope I can use it for somthing lol : I can calibrate that meter with my laserglow aries 89mw I know that is close I just bought it new not to long ago laserglow stamped it at 89mws OH where did you get the paint can it be bought at home depot

NS ---

It's not the real thing but I use Flat Black exhaust manifold paint sold at car parts places. Just a light coat so it's flat black.

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

thanks Mike, I was reading to mix power charcol in your paint and that really makes the paint flat you can get it from the pharmasist (drug store) :)
 
Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

Hey guys,
I have been following your exciting thread closly the whole-time, unfortunatly, I cannot afford to buy a set-up right now, (even with Chris's great-price),as I am setting up a complete machine-shop. Really-cool whatching your progress though :).

I do not have any experience with RF-electronics, but I did run across this PWM on Ebay, intended to release hydrogen from water. It powers up to 30Amp, and produces frequency from 100hz to 15 khz.

I hope this is usefull, I will continue to live vicariously through you guys :)

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

The PWM for these units only need to output about 20ma so I believe that's a little overkill... with a factor of 1500 or so ;)
Furthermore it requires 24kHz.

Charcoal is combustable and probably not good for this coating. I believe the high temp paint used some black metal oxide or compound.
The can only lists the solvents used.

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

thanks Mike I hooked my homade sensor up last night tryed my homemade fenix host with opencan red diode running low then I tried my green aries 89mw thenI tried my red kryton these all did about what i thought they would on an anlalog power meter then I fired flash gordon (co2 12 watt?) and about blew my meter across the room ;D calibrating will probably have to be done mathmaticly lol ;D Yes we aint in Kansas anymore!!!!! 8-)
 
Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

Mike,

Nope, not in Kansas, but tomorrow it gets fired up with my Power One PS, sometime before the turkey comes out of the smoker and between rounds of clay pidgeons and lots of liquid courage.  I'll report back if I don't get electrocuted  ;)
 
Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

You can doit Man you can doit ;D hey spikec I never did give you the model number of my power supply its a Nemic Lambda FS-300A-28 these are labratory grade supplys, if you can find one get one. mine was fifty bucks plus shipping. you can turn the voltage up to 48 and down to 6 volts acording to the manual dont quite need 48 I run it at 30 volts :)     Dark Horse it great to have Fans!!! :D  
 
Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

NS --
Did your head read about right on the mW lasers? You now have taken the quantum step to WATTS. Those sensors are rated for 10 watts MAX. That's why it jumped :D

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

PWM guys here --- I got my PWM working but if I'm at about 8 watt setting, it doesn't ignite and lase ..  I can start high and turn down but it has to make plasma first.

What are you finding?

Mike
 
Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

Hmmm. So you're saying that it doesn't ignite by itself at ~50% dutycycle? That doesn't sound right, right? How is the signal on your o-scope? Did you managde to get rid of the nasty statics? What LC-filter did you go with? Type of PWM-cable? Distance from lasertube?

Re: OUTRIGHT BUY! 15W RF EXCITED CO2 BURNING LASER

I have shortened all the leads going to the PWM circuit and added ferrite blocks. I still have some noise on the PWM input but It's high freq. Grounding the laser body to the power driver hepls somewhat.
I can adjust it from about 4 amps input to full power.

How's the other circuits you guys are using working for you?
