How much mA did You drive your first BR at?

127ma is what it was driven at initially.

Did i write "127" on the underside of your driver? If not, your initial current was 124-125.. If yes, your current at the moment is 146mA.
 





Alright, thanks everyone for your input. I think I'll drive mine at 125mA and see how it goes from there. I can't wait to build mine, I've never seen a Blu-Ray in person before!
 
Good luck, buddy! ;)

You still enjoy it though, don't you? Its cool to know that you built that laser with your own two hands :)

That's true. I guess I just got spoiled with power, so it all sort of lost it's meaning. :o

Just push the diode as high as you can and when it dies out you can start all over again and have some more fun ;)
 
I finished my DDL driver today and hooked up my first PHR803T diode to 105ma- until the lead from the laser diode disconnected to the driver and flashed a big horrible death. :( :( :(
 
#1 38 re-did it to --78ma
#2 78 first dyi a keeper for sure
#3 86 sold to iewed
#4 86 warranty to iewed
#5 100 sold to friend at work
#6 120 a monster a keeper for sure in a host that i got from Ace82 -Free-bee thanks Ace
#6b left in car diode came loose from solder -blew diode replaced diode in unit still 120 ma
#7 ????????? ;D as soon as Kenoms  kryton get here its on baby  8-) not free  :P but worth it I'm sure

so far two of these 803-t's have went to a better place 'poof' my fault im sure .especially if i had used them for what they were intended for :P :P
 
i just assembled my driver and attached it to my host board and am just waiting for my heat sink and she will be shining some blu ray light!

Nice! I wish I could say the same.. :'(. My diode window shattered during the shipping process and I was able to manage pulling all of the pieces of glass out. I hooked it up to the driver, It gave off some light, then slowly faded into nothing. Gotta make some more cash before I buy another.

Also, does anyone have a reccomendation on what kind of a duty cycle I should be using while driving one of these at 125mA with one of jay's heatsinks?
 
I plan to drive it at 110mA, with an adjustable micro drive. I'm also going to order an unadjustable at 100mA to make and sell it to a friend, mainly so if they take it apart and want more power, they can't, so less risk of frying it. :P

mines going strong at 150ma with a ddl style driver inside the aixiz module and no heat sink. i can run it for around 2minutes before it starts to warm up. did you get the other package i sent you yet?

nvm i just checked the tracking. its still in montgomery. its left montgomery on its way to you.
 
Well my first blu-ray was 380mA which i think is a recored lasted 50 seconds but must of been putting out 350mW
 
I have never had much fun with numbers, so even something as simple Ohm's law gives me grief.

If I short out the pot on my 141ma rkcstr, will that give me 282ma?
 
i got bored for a while since i couldnt sleep last night and built one around 175ma. ill have to find a good host and get a heatsink for it b/c it heats up FAST. i got it in a red aixiz heatsink from jayrob atm so i can still play with it tho. :D
 
Gonna put mine togeather tomorrow hopefully. If I get it done before work I'm sure to be the talk of the day ;D. Only problem is that its been awhile since I've used that soldering iron and I turned it on today and it seems to have shorted itself out or something, it doesn't wanna heat up. So I am gonna attempt to use a 10W woodburning pen, it should work plus it has some of the tiniest style tips you could imagine (Perfect for diode pins). Hopefully it all works out and I will have built my first Blu-Ray. Oh and I have one question to ask just out of plain curiosity(Spelling?), if an rkcstr driver was powered up for a very short time without a load, would it kill the driver or would it just build up a small charge?

i would spend the 10$ and go to radio shack and buy another 12-15w iron personally. dunno anything about wood burning irons tho. not sure if it would damage the driver but you should always discharge the capacitors before hooking up an ld.
