The Protective Eye Glasses are now officially part of my shopping list. I was a bit nervous though when that purple dot appeared in the center of my vision. It was kind of nauseating :) Now its time to think about my next DIY... Cheers

Yeah, I noticed that when I tried to increase the current draw setting past 400mA on the potentiometer on the driver, while I was measuring the current draw using my DMM, the DMM displayed only up to 400mA. Past the 400mA point, the DMM displays just 0. Which means the driver can handle a...

Thanks for your persuasive comment. I would rather lose a couple of bucks than to lose my eyesight to an inconsequential beam of light :yabbmad: so one of the first things on my shopping list would be one of those protective eye glasses. I hope mine is producing as much as yours, like around...

Hurray! I have just finished taking apart the BDR-203 blu-ray burner. I thought about buying the 12x blu-ray burner but I changed my mind. The sled came out pretty easily but soldering the pins on the 8x laser diode was a pain in the butt :) Anyhow, its all done so now I'm officially part of...

Okay I've already taken apart my BDR-203 today and put that 8x laser diode into my already built host!! Finally its done. So, I won't be getting the 12x laser diode :D Btw, I set my driver to 365mA and I was pretty amaaaazed at the difference in visibility of the 405nm beam in contrast to the...

If you have a good digital multimeter (DMM), the next step would be to set up your DMM to measure current draw by inserting the red lead on your multimeter into the uA/mA slot. Now you would connect the (-) lead on the driver to the (-) lead of the dummy test load. Following that, you would...

Yup, just like how we humans use monkeys and animals as test subjects to a new medicine before we use it :)

Hey Ultimatum, I built my dummy test load pretty easy. All you do is just get a breadboard solder a 1 ohm resistor & 6 of the 1N4001 diodes all in series on the board, respectively. Then use a two wires and connect one of them to the end of the last diode on the breadboard and connect the...

oops, wasn't thinking clearly there lol. I meant I used 6 diodes and one 1 ohm resistor in series as the test load dummy.

If thats the case then whats the rush! :D I've actually decided not to sell my BDR-203 and just use the diode from it since I would have to pay more to get the BDR-205. By the way, would you happen to know which of the leads of the 8x laser diode is the positive and which one is the negative...

I built my own test load dummy using diodes and resistors. I connected one end of the my DMM to the positive lead coming from the driver and I connected the other end of my DMM to one end of the test load dummy. Then I connected the other end of the test load dummy to the negative lead coming...

Yes, I'm going to be using the same driver as the one I used in my first DIY. I've set the driver to 360mA using my Bluepoint DMM :D That should give me an output of more than 400mW like what Daguin and the rest of the 8timers have. Thanks for the welcome! I've been away for some time...

Thanks for the info, :D but I'm going to build my own driver for this 2nd DIY. I plan to use jayrob's custom driver from my 1st DIY as the blueprint. Heatsink is something I might have to consider from jayrob, just in case this heatsink is not good enough. I think it should be okay since I...

you can buy it for cheaper at around 21,000 yen at Tsukumo in akihabara. I plan to purchase it there sometime soon.

Yes, Archienj7, I might need to make a new driver for this 12x diode. Actually, its my error...I guess 800mA is a bit too much current for this diode still. According to what LarryDFW found from a Sanyo article: Graph of the 12x recording. and it seems that the 12x diode "shows no kinks up...

Hi all! I came to this forum some time ago and after much deliberation, I ordered jayrob's MXDL 4171 version 2 kit and got his 405-G-1 lens to power a BDR-203 8x LD...however, I decided not to take apart the BDR-203 due to laziness on my part and I used a much less expensive PHR diode instead...

Very informative explanation. thanks! btw, with your reasoning your conclusion is that this particular model BDR-205 is using a 12x laser diode that is more powerful than the 8x in the BDR-203? I thought this 12x diode would take a couple of years before it even came out with all that nichiya...

Hello all! Been away from DIY for some time. Btw, based on the specs of the BDR-205, it's supposed to write at 12x speed but read at 8x speed, so are we really talking about a 12x diode here? If thats so then I'd really like to go for it since I haven't taken apart my BDR-203 which I can...

Yup! You can say I'm in the experimental stage. I thought about keeping it at 130mA but then I wanted to see what this PHR can do at 230mA. You see Dave, I don't even think that I'm focusing my PHR that well anyways, since I haven't pushed that diode in all the way into that Aixiz module. I...

:gun: Finally my 1st DIY is accomplished. Laser Diode = PHR-803T 25mA-400mA adjustable DDL Driver = Set at 230mA using my test load & DMM. Host = MXDL 3405 build Host Collimating Lens & Module = 405-G-1 lens Mod Batteries = 3 x Ultrafire 10440 batteries (bought it at a local store) Power...
