The two times I've ordered from AixiZ, my stuff arrived in only 3 days. I live in the southern U.S. Sorry you are having to wait. I hate it when a package lags when you are excited about a project! -Brett

Is there anything cool in the way of a home made DPSS supply that I could find on this forum.  Any threads along those lines you could link me up with?  I mean, the LM317 would do fine for 500mW pump diodes, and maybe 1000mW (although I probably could not max them out or push them to the top of...

Yes, I will search around here for a 9VDC wall adapter. If I get time tonight I am going to start on another driver with the 2nd LM317T. It will basically be a clone of the first, but will be more of a "finished" version...soldered onto some copper clad perfboard (unless I actually come up with...

Thanks!!!  It is quite a bit brighter than the original AixiZ driver and the Snoctony driver as well.  There is a sweet spot on the 25 ohm pot where power seems to be at its highest point.  I'm planning on doing some relative power measurements using a meter and a solar cell as soon as I get...

Here's a picture of the spot on the wall about 10 feet away...the spot size is exaggerated by the brightness and ISO setting of the camera.

Thanks for the detailed description Pseudo. I have had success using this driver to power my AixiZ module whose driver had died a few days ago! However, I did have to remove the resistor and go without it, since I don't have any small value (like 2 x 10 ohm) resistors around right now.  I was...

definately.  I've been trying to measure as much as I know how in this type of circuit, although it will probably take me a while to track down a 1 Ohm resistor (for measuring mV == mA) in my bin or reisistors, as it seems most of what I have on hand are multi k larger sizes.  I also need to...

Yeah, that makes sense. According to Snoctony's data for his C-mounts...2.0v and 2.2v respectively for the 500 and 1000mW pumps. Great! I have some bigger diodes, such as the 1n5404, which are 400prv 3 amp. -Brett

Thanks ElektroFreak!   I need to devise a dummy load that will simulate the characteristics of 500/1000mw C-mount pump diodes.  Should I just find the datasheets and use Ohm's law, or are there other things to consider? Mostly what I've seen about these DIY drivers has been about testing them...

rckstr, Thank you for explaining about the different driver topologies, that's why I am here...to learn exactly these things (and more). The LM317T certainly is working. Since I posted last, I have put together a similar driver to the one popularized in Daedel's tutorial. The picture shows it...

Cool, I am going to read that whole thread about phenol's driver as soon as I am done writing this.  You guys have all been very helpful.  Perhaps this thread will help out other people as well, who are struggling to build these different drivers.  I've been wanting to build my own ever since I...

Very cool. Can you give me a link or thread name for DrLava's "Groove" driver? I wonder if there is a .pdf for it? It would be nice to have an idea of how to populate the 1117t when I do find it. Until then I will look up the datasheet. Thanks! -Brett

PM sent! Phoenix3200, Do you have any pics of the part? Do you know what standard package it was? -Brett

Thanks. Are the 1117's you found there surface mount, or leaded? I don't mind soldering surface mount, I'm just asking to make finding them easier. -Brett

Re: Another AixiZ 50mw 532nm(the new variety) revi True and thanks for reminding me.  I've certainly read a lot of that from reviews and posts on here concerning warm up time of DPSS lasers.  It's just that I think it's nowhere near as bright as any of my DPSS lasers even after reaching its...

I was wondering if anyone knew any common electronic gadgets/appliances that commonly used the LM317 voltage/current regulator? My local radio shack locations are really poor about keeping components in stock and as is the case everywhere, they are mostly a cell phone store now. I will...

Re: Another AixiZ 50mw 532nm(the new variety) revi Kage, In the labby size comparison pic, the Snoctony is on the left (from the point of view of you the observer), and the AixiZ is on the right.  The AixiZ is the larger of the two...but yeah...weird how it basically dwarfs the Snoctony...

Yeah...that was a very cool mod that rog8811 did to create a yellow beam from the DX pointer which had red and green on the same host. Right now I'm more interested in doing my own DPSS. I know it won't be as efficient as something you can buy, and it will probably be more expensive, but in the...

Re: 50mw Snoctony labby Thanks...those inexpensive modules are nice for someone who wants to experiment on a budget. -Brett

Re: 50mw Snoctony labby Here's the beam going through a spiderweb by the stone fireplace:
