Be aware that your CPU may limit what a GTX560 can manage. 6 months ago I upgraded from a GTX285 to a GTX670, but found that my overclocked q6600 couldn't keep the GPU supplied at higher settings. Trying to use higher video quality on BF3 just resulted in my CPU usage going from 85% to 100%...

Re: "CLOSED.!!!" GB: For The New 3.8mm Red Diodes 660nm (Taking Payments for Round 2) Ditto

I use 3 FlexMod N2's in my projector, the connections are wired to terminal blocks, and the diodes are wired to terminal blocks. I can move the lasers around just fine. I have yet to use my P3's , but following the simple rule of never applying power to the diode with out solid connections and...

Never seen a HeNe that required water cooling. My 15mW works just fine on air cooling.

I used to get hit by the starting pulse for HeNe's 10-20 times a day, but the worst was a ganged PSU for lighting 40 HeNe's at once, I tingled for 2 days after that one. :wtf:

Re: GB: For The New 3.8mm Red Diodes 660nm Add me for 2x please.

I believe I have a couple of the HR and output lenses from the first MG builds of the 612nm hene's. They may or may not work with some of the double brewster tubes, because I remember that they used a slightly different mix and pressure of gases than the 633nm tubes. That may have changed when...

I have one of the o-lke housings for 9mm diodes, but the diode fit is so loose, you would need to made something like kiyoukan's insert to hold the diode in place.

The coil will cause the gas in the tube to glow if its still present.

We used to keep one of those coils next to each of the vacuum processing systems for the HeNe's.

Looking at the serial #, that looks like one of the 05-LHR-006's that I made in 1988. The cathode seal and the gas fill tube are the normal failure points. If the Glass to kovar seal looks silvery the tube may have leaked. If the fill tube has been damaged at the crimp, its possible it leaked...

I used 1/2" MDF on my first scanner build, and I constantly have to adjust my farfield alignment. I'm using 1/4" aluminum on my current build.

Just filled up yesterday at $4.27/Gal for 92 octane. Its gone u[p 30 cents in 1 week.

Depends on the lense used, I believe those graphs were done with an Aixiz glass lense.

Re: Ultimate DIY Projector Guide Awesome work. :gj:

I built my first projector for ~600. 3 Flexmods, 20k galvo's, USB soundcard, drlava's correction amp and a spaghetti license. I made some dichro mounts, and got the dichro's from a video projector.

I believe that mount was designed for knife-edging 3 445's. It looks like a mount that was posted on PL a while ago. I don't remember by who though.

Is there an IR filter in the lense housing, if so that may be the reason for the power difference.

I used to build the ceramic package that the die is installed in.

I still have a 486/50mhz laying around somewhere. :huh:
