That particular tube will never output more than about 1.6mW. It was only designed for 1mW in 1985 when I was building them( only about 1% of them ever got to 1.6 mW). If you look closely when the laser is off, you can see the ~0.5mm bore that the arc travels through to generate the gas plasma...

I had mine working fine with Win7, the only problem I had is that I had to reset all the settings everytime I unplugged the USB cable. Otherwise it worked fine until I switched DAC's.

Personally I can't see a bit of 808nm, but its possible there may be some IR flouresence off the surface your pointing at.

Count me for 2 please. Building a 2nd projector and need the high side drivers.

Buy through their ebay store. Just received an order from them.

Did you have a ballast resistor?

I made a 12"x24"x1/4" breadboard about 5 months ago. Drilled and tapped 288 1/4"-20 holes myself with a drillpress and handtap. Cost ~$30 for the aluminum plate and ~$7 for the proper drills for 1/4"-20 holes. And about 20 hrs of my time.

Neither, its for a projector.

Yes, my 50mw green has a much more visible beam than my 230 mW blue in my projector.

What that means is that as long as you have enough input voltage, the output will match the diodes need, but if you don't give it enough voltage it will not supply enough output. I had that issue with my FlexMods when I tried to drive a 405 with a 5V PSU. The driver would only supply ~4v to the...

2 LOC's in series would require ~6v from the driver, which means you would need at least 7.5V from the PSU.

It's possible to do it many ways, just depends on what you have available. flecom's projector has red as last(green, then blue, then red) Mine is strange. My green goes in a 'U' shape off 2 high reflect 532nm mirrors, my 445 passes through the first green mirror(~90% passes), and my red...

QS2 can do effects and color cycles to cues.

Kind of depends on what you need it for. Otherwise they appear pretty much the same.

Ditto to both. I recently upgraded my main projector to FB3 and QS. My Soundcard DAC will be going into a secondary single color scanner. Quickshow is extremely powerful, yet very easy to use.

Keep in mind, if you have a green module, they are case positive. You would need to insert the batteries backwards to get the correct polarity.

500ma is pretty high for an LOC. You should probably back it down to 400-420 ma for a reasonable lifetime, especially whit no heatsinking. Edit: damn EF beat me. :)

Laser with red and black leads for power. Determine the current that the laser is driven at. I did it using 2 different methods. 1. Break 1 of the power leads and insert a 1 ohm resistor, and measure the mv across the resistor. 2. Measure the power of the laser using an LPM, then connected the...

Sure I'll get it tomorrow.

I asked snoctony about the analog frequency, they said that model is 1khz, which is really slow for a scanner. Try this one for starters(532nm 50mw adj power laser TTL AC 90-240VAC - eBay (item 360292199009 end time Aug-30-10 16:37:38 PDT)), it can be converted to analog by connecting it to a...
