I've got a closet full of microwave transformers from my other high voltage/high energy physics hobbies. I've used rewound microwave transformer based supplies for a lot of applications: Filament supply for an 833A tube, after rectification and smoothing as a power supply for ZVS flyback...

I'm not using any additional cooling, however, the heatsink on the MOSFET gets pretty warm very fast with the pot maxed out on that switching driver. I would suggest (as others have) blowing a fan on that FET for extended runs. The laser head seems to stay cool at 10 minute runs, although I...

Re: Successfully changed the c-mount on my Aixiz 5 Thanks Jerry!!  I'd call that a repair/mod if I had to be honest.  A lot of what I did here was inspired by Wannaburn, and things I've read from Sam's Laserfaq.  The DPSS section is incredible!  This is just a small step of training in...

Yeah, I ran the test again just for you (in fact it's on the laserbee right now as I write this). It ran right up to a 113mw peak this time, then settled down to around 105 or so. It will plateau at close to 110 for a while then trickle down to 100 or so. After doing this a couple times, it...

Good stuff guys, thanks! ;) I certainly want my LaserBee I to live a long and healthy life. I haven't even gotten a chance to try the datalogging function yet! -Brett

Thanks for the tips. Yeah, with 808 I have been using my Sony Digital Handicam on Nightshot (0 lux) mode to view the IR dot size. It actually works quite well. Some of my labby 532 modules have some pretty narrow beams at least until they reach about 25' from the aperture or so. For these I'll...

You and Jerry have warned me about Thermopile damage.  I have read the manual (although it was a quick skim read, in all the excitemnet) and I recall it saying that the thermopile has been tested at 1.1w with a 1.0mm diameter beam for extended periods of time. Should I worry about shining beams...

Re: Successfully changed the c-mount on my Aixiz 5 Thank you ElektroFreak!!  Here it is after last night, when I turned up the pot on the Snoctony driver I was powering it with. It's the most powerful 532nm laser I've owned now...it's burns electric tape like it's nothing and who knows what...

Here's a Laserbee measurement of this Labby running for 5 minutes.  The pot remains untouched!

Re: A quick and dirty enclosure for my Aixiz 5v la Here is the laser operating for 5 minutes (under measurement) with a Radio Shack adjustable wall adapter set for 4.5vdc....actual measured voltage: 5.5v ...despite the discrepancy between voltages and power readings, the beam still looks about...

Re: A quick and dirty enclosure for my Aixiz 5v la I guess if I was going to sell something I had put in a case with a switch such as this, I would worry about conforming to U.L. or some standard, but mainly that switch was just a victim of someone who was in a hurry to have a portable heat...

Re: Successfully changed the c-mount on my Aixiz 5 I did a 5 minute power measurement on my modded Aixiz 50 (my LaserBee I came today!!!).  It's pretty cold here today, so it could probably reach higher powers over a 15 minute warmup so as to allow the KTP to reach optimum temp.  In any case...

Re: Successfully changed the c-mount on my Aixiz 5 One final picture...the c-mount and its brass holder. It was actually very easy to replace. Someone recently said on another thread, something to the effect of "The c-mount isn't for hobbyists". I disagree.

Re: Successfully changed the c-mount on my Aixiz 5 Here's the other side, with the beam expander. Next in line after that is the focusing lens on the front of the Aixiz heat sink.

Re: Successfully changed the c-mount on my Aixiz 5 Here's a picture of the cap I mentioned that contains the crystal set on one side, and the beam expanding lens on the other:

Re: Successfully changed the c-mount on my Aixiz 5 The Vanadate should be cooled and the KTP heated and kept its optimum temperature, if I recall correctly.  I do have a few TEC's, and I plan on trying this in the future, but this particular laser, being designed for Hybrid Casix type sets...

Re: Successfully changed the c-mount on my Aixiz 5 Thanks...you know I'm interested in DPSS experimentation!  8-) The module in question is the one I showed you in its disassembled form in those pictures I sent you via email in that zip file.  It's really cool to observe what happens to the...

Re: Successfully changed the c-mount on my Aixiz 5 Here's a beamshot of the restored laser...it's much brighter than it was when I got it....although when I got it, it was definately running under spec. Now it's super bright. When the laserbee arrives, it'll be sweet.

Today I got my Aixiz 50mw labby working again.  It had died, first...due to failure of its mains powered switching supply.  I had then restored it to working order once again using my LM317 supply.  Unfortunately I ended up frying the c-mount, probably by disconnecting the module and...

Re: Sled extracted from Toshiba HD-A2 HDDVD player Ok, I found even more information about the DT0811 (DT-0811) here: http://www.laserpointerforums.com/forums/YaBB.pl?num=1215000888/6 -Brett
