Here's an old thread on dummy loads, from a schematic from Life long experimenter - It can be done . I had put together a dummy load module inspired by this schematic with some very inexpensive parts from my bin. http://laserpointerforums.com/f38/need-dummy-load-phr-803t-diode-43003.html Hope...

Hmmm. Thanks james1095, I will heed your advice. I don't wanna accidentally destroy any of my HeNe tubes. It is indeed some intense ionizing voltage and it wouldn't take much to zzzzap one of 'em. I think I'll just stick to the brick PS. :lol - Robert

;) LOL! I believe the misinterpretation comes from the fact that in French, the verbs walk and work are the same. "Marcher" can mean both. N'est-ce pas, Tirano01? :D Robert

Wow!!! This I have to try! I happen to have a 20" TV that got recently retired from service. If I get my MG tube to lase, this will be an extremely cool experiment. So the flyback out is connected to the cathode and you're just waving the ground wire near the anode? Wouldn't there be some...

BTW, Glad you're back TJ. It's not the same 'round here when you're not around! :D - Robert

Hey you guys! Have a great one! May your holiday cheer be of the single malt kind, and may the new year bring you lots of new lasers! :D Robert in Montreal (having large quantities of holiday cheer before the xmas party tonight! LOL)

Bienvenue à LPF! N'hésite à poser des question, les membres sur ce forum sont sympa et ils connaîssent bien leur hobby! Welcome to LPF! Don't hesitate to ask questions, the people on this forum are real nice and they know their stuff! - Robert in Montreal ;)

Re: Powering a 12v HeNe PSU? Good deal on the GrHene! Let me know if you need one of those little female quad connectors, I might have one in my parts bin. - Robert

Ten bucks for a green HeNe? I am green with envy! LOL That's a heck of a cool new toy. How long is the tube? What are you powering it with? - Robert

Welcome! I read your story with interest, because you were lucky enough to acquire one of those cool lasers from Xerox. I was a maintenance tech for Xerox way back in '88 and I tried my damnest to get my hands on one of those lasers (I was working on the mighty 9700 laser printer) but to no...

I use the "liquid tin" solution by MG chemicals, it deposits a nice, even coat of metallic tin on the copper traces, all is needed is to wash off the board with a bit of hot soapy water and you're done! As a bonus, the tin really helps when you're soldering, but the bad side is that the solder...

Welcome! You will indeed find a wealth of information on anything from diode specs, construction tips and great reviews. Check-out the stickies and tutorials, and keep us posted on your projects! Robert

Laser diodes have these annoyingly tiny tiny little leads that aren't compatible with big clumsy fingers... My first attempts at soldering wires on a diode ended in catastrophic solder blob messes. One trick I use now to solder wires to a diode is to "pigtail" the wire itself. After pressing...

Aah, misuse of lasers... just this morning on the local news, the *headline* story was how usage of laser pointers have dramatically increased around the Montreal intl. airport to the point where pilots report an incident nearly every week. These are the same dumbasses that are going cause the...

Doing fine Jerry, doing fine... I have undertaken some major home renovations (floating floor tiles in my bedroom), my house is an utter mess. But mid-september, I should be all done. Oh and i'm organizing a cool rock show with Mahogany Frog (a great band from Winnipeg) on September 9 and a...

Yeah I know... I'm French so I always cringe when I hear the "jjohn-rah" prunonciation, the real way to pronounce it in French sounds closer to JAR, with a slight nasal inflection* to the A . The French syllabe "EN" has no equivalent in the English language, so it is understandeable that...

...For example, a couple of star wars animations on a beloved veteran member's posts, that freezes my computer for a whole minute everytime I scroll to his sig. wink wink ;) I have no need for a sig, and if I were to add one, it would probably be a clever quote in text format only. I've noticed...

Well said! we do indeed learn through our mistakes. It's always infuriating to utterly destroy an expensive component because of carelessness or plain stupidity (hint: HeNe tubes have this annoying tendency to roll off tables). ;) This is a good list to start off. Let me add another item: 13)...

Hey Gray, Nice website. Good-looking hosts. You got my attention! ;) Will you have a price list available soon for your lasers? Thanks Robert

Aah, a DXer! Welcome to the forum, you'll fit right in! Check out Sam's Laser FAQ at Sam's Laser FAQ: Welcome Page if you need any info on gas lasers or diode lasers and their principles of operation. A few places I would recommend for laser stuff are Jayrob and Hightechdealz for hosts...
