Re: Xbox HD DVD Laser
I'm getting a couple of these drives.. what they're only $50.00 now.
I'm thinking of using the ddl circuit with a 9 volt battery and trim pot. From what I've gleaned here max current is 35-40 mA (@ 4.5-5.5 volts). Does anyone have any information on the diode - power curve, etc. ??

Re: Xbox HD DVD Laser
Is the diode a 5 or 9 mm can? pics?

Re: Xbox HD DVD Laser
Can hardly wait to get my paws on one of these diodes!! Must have a black light laser.
My brother is sending me an xbox hd, and I might also get one locally by this weekend.
I'm planning on using the 'ddl' circuit with a 9 volt battery. I'm scavenging a Meredith brass housing with glass optic from one of my two 635nm pointers.
Not certain what current to drive it @.., but probably less than 35mA (??)
Picture of the under construction housing. Another epoxy wonder.

Re: Xbox HD DVD Laser
see i'd do something in a project box but i really want it in a small portable flashlight since i have no possible chance on putting one in a pen
going to frys today to get a digital multimeter, always used my dad's when i lived at home.
gonna buy a somewhat cheap one, wish i could get a fluke or something but ohwell.
i really wish i had some specs on the diode so i can just figure a way to make a driver that will fit with correct current and what not. driver is only thing holding me back atm, that and my module needs to arrive but basically the driver. scared to death of killing the diode also

Re: Xbox HD DVD Laser
The project box I'm using is plenty small and portable (from RS).. however it certainly isn't nearly as sexy as a nice flashlight body.
I'm using the DDL driver. That's what the potentiometer is for, (in picture) to adjust the current. When first testing the diode I power up the circuit with a multimeter attached and the pot turned all the way off. Then carefully keep an eye on the current and the diode while slowly turning up the power. I'm going to try to keep mine below 35mA, but since each diode is unique you should really try to play it by eye. 35 mA might give 15mW on one diode, but barely 5mW for a different one. Sometimes you can estimate the power level of the diode if you know the slope of the power curve. Note the current it first starts to lase at (as opposed to being an LED, which is how the LD acts at very low drive levels), and each 1-2 mA over that gives you +1 mW.
I wish there was more information on the diode. Adjusting the power for the first time always gives me shaky hands. The diodes are easy to blow and there's $50.00 gone.

im scared im going to screw mine up.
as a driver, this looks perfect...

Re: Xbox HD DVD Laser
Yes that should work. Jayrob is using the same driver I am - the ddl circuit. You just need to build the circuit with a trim pot (potentiometer) so you can slowly adjust the current up to the correct level. At the least you'll need a dmm to do it.

Re: Xbox HD DVD Laser
Yes, and if you did your homework you'd realize Jayrob is using the same driver I am... the ddl driver. See this thread:
http://www.laserpointerforums.com/forums/YaBB.pl?num=1185701612
The driver is very simple and can be made very small, assuming you have the skills.

Re: Xbox HD DVD Laser
if i can find the parts at frys, i'll be able to make it that small.
i just don't know parts i should start with cuz of the diode power difference.
maybe sometime when i get a chance, i'll start looking around more to find out.
shouldn't be too hard to make it work with 6V

Re: Xbox HD DVD Laser
hmm. turns out i'll need to use a different driver as that one doesn't work with only 6V. 9V is not an option for me this time around. guess i'll have to buy a driver from bluefusion or drlava or someone assuming they have small enough drivers for my flashlight with 6V

Re: Xbox HD DVD Laser
Well, I got my xbox hd from Amazon yesterday. I got the diode out, but it only lasted a grand total of about 15 minutes at 40mA. Perhaps 40mA is too high?! Sigh. Just enough time for the glue to dry. It was really cool while it lasted, but more work that it's worth for 15 minutes of fun.
You can see my write up on it here, in 'experiments & modifications'
http://www.laserpointerforums.com/forums/YaBB.pl?num=1206117400
I'm planning on trying this again, but perhaps not for a week or two. These diodes are just so unbelievably fragile, even when you're careful. It doesn't help we don't know the specs on the diode either.
