Now with the casio diodes, these are obsolete :(

I tried to sell out, but the sale was contingent on the buyer's ability to sell on ebay, long story short she was attacked by several people on ebay and demanded the deal be cancled. I am stuck with a lot of stuff I cannot sell. To make it even worse, I placed an order from axiz to build blue...

My paypal account was frozen last December when they did a credit check. Thing is my credit is about average. I found that pay-pal is required by most if not all internet merchants to survive. Axiz for example uses paypal as their internet and credit card processor. As a result all my credit...

The white balance on the projectors is difficult to achieve, the rainbow issue is an artifact of DLP, the bright side is they make about the best eyecandy projectors i've ever seen :D

possibly, I'll try to get pics of the parts with descriptions of their functions soon. i may offer the dichros chopped in quarters on ebid.net

The beam in the projector is pulsed. The .707 thing was a discovery from years of playing with laser diodes .707 of the COD value gives the absolute theoretical operating power that can be safely sustained. COD is the minimum value of drive current that causes permanent damage to the laser...

The condenser from the red LED or the integrator assembly plus the zoom focus lens will make it a beam you can focus at 10's of meters and reasonably collimate if so desired.

We need some other people to test one to destruction for the cause, I am sure the .707 works for shorter wave IR and red diodes, but of the new nitride based blue ones I am still a bit unsure. I do know for sure they are run at about 800mw average power output in the lowest setting of the...

While most focus is on the diodes these things have a lot of nice useful optical parts inside too! In addition to some nice condenser lenses you get a high Power LED, a few dichros and a few FS mirrors as well as a VERY nice zoom lens. One thing I fond the zoom lens is great for is making a long...

And the tortured diode still lives, although at about 60% efficiency! Not to sure how long it will live...

mw for mw these blue laser diodes are the cheapest wavelength currently available in a new non-surplus diode.

Nice that is really beginning to look like we have 2 distinct types of diodes.

It switches a normal silicon rectifier diode in and out of the circuit. I made the enclosure on a break press from 2 pieces of aluminum. The whole case acts as the heatsink.

Glad you liked it! Thanks :D

Yup that's called "suing into submission" , and it is intended to "win" by bankrupting your opponent. It is the favorite method by giga-buck corporations to eat up competition.

The lab laser is running on a 6V 1.2A power converter, the portable unit and the tiny module uses a DC-DC converter that was meant to charge lithium ion cells originally. The blue balloon reflects and diffuses the light so it did not pop instantly, similar to how a red laser diffuses in your...

Deep blue burning and melting stuff. My portable has 750mw and the labbie has 500mw and 1.2W Make sure you don't look into beam with remaining good eye! LOL HNvxYFOz3xw

The failure was classic partial COD, permanent mode shift and power now at about 300mw at 650mA. FWIW 6v and 1 ohm resistor will do nicely to run it balls to the walls on most of them. These diodes are like people, different modes, different personalities :)

Mouted in axiz module with additional heat-sinking to aluminum case. The lens used is cheap acrylic with back opened. Used a custom current regulating DC-DC upconverter circuit to drive it. Ith 220ma roughly 30mw at Ith; Po @ 650ma 615mW; Po @ 1A 1.18W Tested this diode without a lens because...

"Due to a potentially hazardous situation and the possibility of litigation it was decided that rendering the 445nM forum inoperable is in the best interests of the community at large and for the safety of all participants here at PL and the public. The situation is getting increasingly...
