dvd players/burners are a great source of tiny 4-10uF capacitors. i took some time to salvage and measure some caps from a pioneer 215 (the SATA version of the 115D) for people who don't have a capacitor tester. most of the caps are in the same spots for the 115D as well. these caps are useful...

The driver in my 30mW green was playing up, it was under driving the laser most of the time, so much so that it wasn't lasing green. I measured the current, when it was working it was 250mA, when it wasn't it was at 100mA anyway i thought, screw it i will just throw an AMC in it and drive it at...

I got my blueray going without killing it and soon got sick of it being effectively a "labby" because of all the batteries and large 311 driver. and i couldn't find a case big enough. anyway, some of you might remember the thread on using a smps with the lm3410 this driver uses the same chip...

i just bought another 112D drive to harvest, i opened it up, desoldered the ribbon strip and shorted it with solder, i then pushed the diode out of the heatsink with a pair of plyers, pushing on the edges of the front of the diode. i put it in a module and tested it with an lm317 circuit with...

Hi all. i have been looking around this site a bit, and it seems most people are using constant current sources or bought drivers. anyone successfully made a driver with optical feedback? I was looking at some of the drivers on sams laser FAQ and it seems the diodes i encountered from dvd drives...
