Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Actually, when I first saw it, I thought it might be in the 49mhz band somewhere... You have a freq. counter don't you? :-?

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! ya, its hard to say what all the added parts do to the tuning of it. The rectangular metal pieces and the close proximity to the base portion would lower the frequency some I would suppose due to the added capacitance... :) mounting this in ANY...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! You know, its about the right size for a center loaded 10meter antenna isnt it. LOL, key up the 10 meter rig, and burn a hole in the wall accidentally... ;D

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! I wonder what frequency it runs at. ::)

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! I am also, KB5UNZ 8-)

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Thats a VERY good question, I was just sitting here thinking about how I was gonna mount it all, I think Ill try a pvc pipe if I cant find anything else suitable. At least its plastic, and might make an interesting looking laser. :D I was also a...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! ;D ROFL!

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Hey Mike, have you measured the current draw from your laser yet? The power supply I tested mine with only provides 29v @ 7 amps... I'm kinda worried, it might be bad for the laser to not have the current it needs. Although it makes a NICE hole...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! lol, well, I made some videos, no one wants to see? :o

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! :D got my lasers! [smiley=2vrolijk_08.gif] Thanks Chris! I think his name is really Chris Kringle! ;D Man, these were packed so well, it took me 30 minutes to get it unpacked trying to be real careful. Soon as I get my pwm circuit built, ill...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Thanks Mike! :D you made my experimenting with components less work, now I know what to dig out of the parts bin! I don't have freq counter. So, about .007uf for c1?

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! yep, I was referring to the microprocessor controlled circuit. Although, you could just run this pwm circuit at an audio frequency and you would definitely hear it, as a matter of fact it would probably be so loud it would be very uncomfortable...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! ok, cool, I wasn't quite sure of it.. I haven't built either one yet... so put a cap to ground on pin 5. like in the other schematic, I thought this one might be a little easier to read for some people, you don't really need the second pot...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Heres another circuit, this ones a little simpler to read. :) I guess pins 5 and 7 arent used?

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! ya, the HV is only about 15 ma isn't it? :)

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Mike, you mean ma? not mw right? :-?

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! WOW! so the minimum is 7w? ! I wonder how long 20 aa nimh 2ah would run it for! 10 min would be good! so it would be 17 x 6 x 6! WOW! Talk about an impressive laser! Nightstick, what did you use to control the pwm? Or did you just tie it to 5v...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! wow! I hope mine are as powerful when I get them! :o :o :o that is amazing! was it labeled as far as a power test or anything? Chris, did you do any kind of tests to see if these are actually doing over 10 watts? Just curious. 8-) I don't have...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Pretty much any goggles will protect you from this laser, what I don't know is whether or not they need to be certified to do so, I would think you should still be very careful in choosing good goggles, I have seen some with side holes in them...

Re: GB LIVE & OPEN for Small RF 5-10W CO2 LASERS! Im almost certain it will not see the beam from this laser. if the lens is glass, it wont even be able to pass this wavelength. ::) Remember you need a znse lens to focus this thing. I have seen a -znse on ebay, and a +znse to make a beam...
