That pinout diagram I posted might be misleading you. That is for PLT5-520, which is indeed case positive. My diode has anode on pin 1 and cathode on pin 3. Inside I can see bond wires connecting the LD die to pins 1 and 3. As far as I can tell, the case is neutral. And there are no more...

It appears to be case-neutral. There's a "76 Y0" marking on the side of the can.

This is my first post here after a very long time. I recently bought what was supposed to be an Osram PLT5-520 diode from techhood https://www.ebay.com/itm/OSRAM-PLT5-520-50mW-Green-Laser-Diode-TO18-5-6mm-New/143292564817. I used this driver set to about 100mA...

you won the giveaway? :) well... photonicinduction FTW :D

diamond is the best :D followed by colpper and and aluminium... brass is definitely not as good.

that looks sooo awesome... like the USS Enterprise ship from Startrek :eek: so, who's gonna extract the diodes? :D

tl;dr. yeeaaah, trip to Andromeda any1? got 3 free seats in my car :crackup: and btw (@Benm): the world's longest laser connection was done somewhere in the 1970 (don't know exactly), they used some huge <1mW IR HeNe to transmit audio over something like 100 miles... (this was posted here some...

that power supply should be powerful enough to power 4 diodes + drivers, that means 4x as powerful as for a single unit. so, the answer is NO.

it's not that simple as you think. you could knife-edge 2 and 2 diodes together and then combine these 2 beams using a PBS cube. it would be very hard to make that assembly reasonably small and portable. also, you would need LOTS of power to drive it (like 3S3P LiPo pack for a reasonable...

this looks to be a red and IR diode in one package, rated for only few mW's. if you want a bluray as your first project, you'd better pick up a PHR-803T or 805-T, build a simple LM317 (DDL) driver and set it to ~100mA

oh, that just looks sooooo cool :drool: how much did it cost?

DX has it's xpg r5 version: FandyFire 2100 CREE XP-GR5 5-Mode 350-Lumen White LED Flashlight with Strap (1 x 18650) - Free Shipping - DealExtreme unfortunately, there seems to be problem with the driver. I've got 1 on hand to repair, and the driver is burned. this light needs other driver 800...

flexdrives can't handle that. @kmor: that was my try to memorise the mode while the switch is pressed (and power is turned off). I'm not an IC programming expert, but I know that you could use a small capacitor and use ADC or comparator to watch the voltage (like this:) int mode; //stored in...

as previously said, the modes work by modulating (switching on and off) the current limiting part of the driver. this modulation is usually provided by a microcontroller. btw, microboost HAS modulation input and can be modded to accept TTL input (try searching "microboost ttl blanking") how...
