Re: FEELER: 2$ copper diode modules ALL SIZES very interested. im looking to buy around 30 to 50 units. aixiz is to expensive.

IMHO never leave it out! But why not go to the crap shack and grab some? The diode does not make that much heat but its all about life the better thermal transfer the longer life and same for a driver or less chance of it failing.

Well a better option would be raster scanning but with that your are making it harder. A good way might be to use 2 stepper motors and drive one coil constant in each motor and use the other to vibrate it. they should be fast enough to do raster scanning. Or 2 spining disk mirrors from laser...

Also you guys need to note that these diodes are not made directly by Nichia, They develop them and then another company makes the diodes for production sales. These diodes do not cost very much to make material wise. The company has been around long enough that the cost is very low and the...

Send me a PM with what you want done if you have a drawing or contact me on skype. I have a full set of metric and English taps/die's as well as a very nice lathe that can do any thread i need it to. So make a sketch or something and you might be able to get more help. I also live in the USA in...

If your looking for production work try emachineshop Or if you are just looking for help try CNCzone

Those look nice i wonder what he would have charged for them. Im buying alot of copper aixiz modules as of late as i just love them so much. So now that i can add this to them they are even better and should give our diodes much longer life. I also love the fact that if the diode dies i dont...

There is, if you make a 4mm hole for the wires that is plenty of room for wires plus heat shrink. And it gives you 0.8mm around on the back side of the diode for thermal contact to the aluminum. And you get the nice ability to just remove the diode by unscrewing the 2 pieces as its no longer...

I was looking to get something like that made in mass but found the cost was not worth it and this solution was super cheap and works almost as good. And being so simple it would not be that big of a pain to make out of copper. But it does need modifications to the aixis housing to work. You...

thanks wanted to find a good way to hold this diode and this seemed like the best way.

Well im about to finish my testing, Take a look to see a fun way to use these diodes http://laserpointerforums.com/f42/improving-aixiz-module-diodes-heatsinking-73446.html

So this is a easy way to improve the ability to heatsink diodes. One of the main problems is when we press in diodes they cant be removed and are not heatsinked on the back side of the diode. That is a large surface that is left open. This new way makes it non press fit. This will also show my...

honestly go with a 445nm diode. They are very bright and not that expensive ad can be modulated very fast.

Well for 205$ ish you can get a 400mw green laser from o-like.com I love mine and many others do to. Best bang for the buck for green lasers. Crown upgrade 400mW green laser torch/adjustable/waterproof [OL-CGL-400] - $205.99 : Zen Cart!, The Art of E-commerce But that is a very powerfull laser...

you could go faster. But there is a problem, green lasers dont modulate as fast as others due to they are not diode lasers like in dvd burners or video projectors. They use a IR laser diode as a pump for a set of crystals to make the green. So they do not always respond very well to very high...

Well for that high current you may want to look at the 9mm 445nm diodes, they cost a bit more but should be able to handle those higher currents longer, but might be best to wait till the end of this week for testing to be done.

that last image looks kinda like a fingernail pressed into the compound.

they are used alot more by people who build projectors. They are commonly used in lpc arrays to help "save" the diode. But it never works as they still die. Most times once your build is put together the threat of esd killing your diode lowers alot. Also the fact is you can build a better esd...

So now we get to tell bill to go screw himself with his lasorbs!

Jerry i have had your meters. i even had 2 of them side by side along with mine. And found your meters were out of spec to each other by about 3mw. Both sensors were nice no dust, no damage that i could see but they were off. So after seeing that i decided to calibrate mine to yours that read...
