Re: "CLOSED.!!!" GB: For The New 3.8mm Red Diodes 660nm (Taking Payments for Round 2) These things happen, dont stress Angelos. It will be interesting to see if the 5.6mm ones are good, if not maybe post a shopping list of the other stuff you can get?

The DVD burner diodes are usually fairly low power (75-150mW) and are semi-visible to the human eye. I think 808nm would be better - you can get high power diodes cheap on ebay as they are used in green laser pointers (frequency doubled in a crystal) among other things. You can get 500mW to 1...

Well it's a bit hard to tell visually, especially with blurry pics and the thing half covered in potting compound.. O-Like are usually pretty good, what is/was it? (wavelength power etc). Also how do you know its underpowered? Did you check the batteries were charged, in the correct way etc...

That looks EXACTLY like the patten on my Mitsubishi ML501P73. Same symptoms, it's drawing 1.4 amps and is putting put 4mW according to my LPM.

OK. My hand is raised. I personally prefer to press the diode straight into the heatsink and not rely on heat transfer between an Aixis module and host, but then I guess with 3.8mm and 9mm diodes now common you would need three different models for this. *hand still raised*

Hmmmm you think they will enforce this? I mean, we are all on the same side... "Thanks for choosing to bid on or buy this item. Before you do, please read this important information. This item is regulated by Part 121 of the International Traffic in Arms Regulations (ITAR). By bidding on or...

Wow, very slick and professional looking!

Hi John, Nice to have someone on who is closer to me than Sydney or Melbourne! Maybe your eyes are just trying harder to focus on the spot and its excersizing the muscles or something? I find my eyes are more fatigued when looking at lasers if anything. I hope you have eye protection? Andrew

Wow cool. I have often thought about that too, the preditor laser. Great implementation Mitch! You could use a reamer to open the holes up a bit and use some thicker shims to help centre them, or maybe a grum screw front and back and"see saw" them against a thin shim in the middle?

Sorry been out of town on business. Take your pick, I haven't used either and eBay is the luck of the draw. One thing i will advise is to put some nail polish or glue on the pot after you set the current correctly so that it doesn't move on you and put too much current through the diode. If you...

Ah, interesting. Thanks Cyparagon

There are lots of drivers on eBay, here are a couple of them, you can probably find something cheaper though; 660nm red laser diode driver (HTV Inferno 2.11) | eBay 2X 3V Laser Diode Driver for 532nm Green 650mA & 200mA-240mA 650nm 660nm Red | eBay

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please If you show them I guess it means hopefully we won't have members fighting each other for stuff as everyone *should* be nice enough not to bid against you.

It would be interesting to measure the temperature difference between the two halves of the TEC to see how hard it's working. The X drivers are just paralleled and the TEC is obviously happy at 7.4 to 8.4 volts?

Jeff, I think the time has come to buy a 3.8mm press, a 5.6mm press, and a diode extractor. I'll PM you in a minute. No, doesn't matter how long the wires are but if they are too long you'll end up with a rats nest and too short and you will have trouble assembling and disassembling things...

Ahh, interesting,i didn't know that Dan. I was going to get a mill for making PCB's at one stage, but I have heard of using a CO2 laser to burn resist (i think they used paint) off a board, that's a good excuse for buying a CO2 laser. Of course one this size could just cut the copper!

Wow talk about micro surgery! So you don't have any holes in the host, the fan just blows the internal air around the case? EDIT sorry just looked at the photos again, missed the holes first time I looked!

Very interesting! Nitrogen, carbon dioxide and helium? Interesting.. A really big CO2 laser with the other cases as a buffer or to help excite the CO2? Huge bore and mirrors, I'm guessing its a multi kilowatt device.
