hey MRI3T, welcome to LPF. wait till you start collecting all the wavelengths! great bio, be sure to check out Geeks corner threads. I bet you could be a great contributing member!
I double checked with her today.
-Proper voltage to the lab driver: 12VDC ✅
-the modules were all offset so the beam would appear to bounce off the sides of the tube. ✅
The museum said they worked fine for a few days then dimmed, then death. We may never know.
I agree laserBee we're not...
I know, I'm that noob being like FIX itttt. But I can't diagnose the problem either from a few photos. Nonetheless I'd like to be able to offer a solution.
Let me ask the question differently: other than CNI or another high end Lab laser supplier can anyone suggest a company that sells quality...
Hey folks,
I could really use some advice. I'll try to keep this short.
A few months ago a friend whom is also an engineer employed by a major company in the Illinois had been given a project to build for a museum. The objective was to demonstrated the properties of a coherent beam inside an...
I'm not positive what they actually cut it with; the guy said ethanol and I think he was implying maybe something used in equipment or maybe cheap home still of ethyl alcohol.
Either way it tasted awful. Coincidentally they sold gasoline in the same liquor bottle roadside. Haha if you've been...
Oh the international license fiasco, I went there shortly after Seoul_laser did back in '12 and the biggest issue was with motorbike rental company. They tried to charge us 700usd for a new scratch on the skid plate. With our passports being held we had to bribe the local police to retrieve them...
Ouch, burn. The FDA calling out specific companies.:spank: Furthermore they noted Laserworld seemed reluctant to make hardware modifications. I don't own a projector but thanks for posting.
I have a 240vac powerstat variac that should suffice.
I might do some testing to see if I can short the secondaries of the large step down transformer and run the primary in series as An inductive ballast for the pole pig.
If I can't use the large XMERs for anything I might cut the winding off...
10kvA pole pig! 14.4kv for my next tesla coil :whistle:. I also have some massive transformer cores I might use for ballasting.
Questions for someone who has worked with these before. What's the best way to measure limited current on the output side?(target output would be 500mA) I'll be...
Today I'll be back in the shop to take a look at the rest gutted welding machine. Those visible leads were connected to a plethora of switch options from high range, low range, reverse polarity, even an ac-D.C. Options. No big smoothing capacitors but trust me guys there's olddddd technology in...
Hey folks, Im bit perplexed by this transformer configuration though I believe it's basic.
I pulled it from a very old miller welding machine and plan to use it as a ballast for a 10kvA pole pig. The core(s) seem to be large enough(100kg easy) where saturation will be less of an issue. It...
Awww yeah, the diode stash. Those coveted binned diodes hang in the threads of this forum:) all in good fun.
I'm home at the moment so I might see about adding some more shots. The color is difficult to capture on camera then describe how it appears to the eye.
Green is really a brilliant...
Here's what I have Paul, yes I do believe I have a laser closer to 510. The 7B147EC91. I also fitted the laser with an acrylic lens and get a similar beam profile but it is better.
Is there anyone selling spectro'd diodes in the 502 range?
Great information Paul when I return home I'll be able to confirm. I did try an acrylic lens but with the spring it bottomed out in the module barrel. I didn't continue to fiddle with it.
Nonetheless it's a good star pointer!

friends, it's been a while but I haven't been far. In the quest for cyan i sacrificed an arm and a leg to purchase the Surefire X400 green laser/light weapon attachment. Price: $699:(
This review is not on the Surefire light but mostly a BRIEF laser comparison...
