Hello again, i wondered what to do with few IR diodes i found in scrapped dvd burner sleds.. they are all 48x CDR and 32x CDRW.. what is the max currentage for these for them to max their optical output and actually not die in weeks.. i was searching for the info at rog8811's site, but...

i tried to turn it on before i take it apart.. and the red was definitely the one with 3 pins in a row..and i took apart the entire sled and found no D shaped diode.. in fact there was 1 this abnormal diode and 2 chip type diodes.. i was really surprised in a bad way.. never gonna buy another...

I am going to buy those 9V from DX.. i dont need for it to last long.. and am going to make it so i can attach the flashlight case with my LD to the power socket.. OT .i bought samsung SH-223F for about 10€ from a local web auction.. because it was cheap and it was suppose to be 22x .. but when...

I know that the regulator will set the right value for me using the right value resistor and I know 280mAh is not much, unfortunatelly nobody sells these 9V rechargables anymore. I wanted 2 lithiums in a form of AA/14500 is the number i think.. but those would give me only 7.2V which is a low...

Hello again.. will this battery be alright for any diode in the driver? I mean, whether i am using bluray or high power red?

nevermind.. thank you for your comments.. problems solved:) i have a 47uF/35V cap in the circuit.. but i never shorted it out. when exactly is it recommended to short the cap out? the cause of the LD death must have been the cap, because im using 9V now and everything works as it should.. no...

thank you dr-ebert -and my power source is usb connector.. or 4xAA rechargables.. with 16x diode it gave me 2.43V and 130mA, which was enough to burn the black tape and light matches.. and btw i used the 5ohms when i was experimenting with those 9V of input voltage.

how did you get this number? I confirm it. And the max current is 270mA or so.. measured thats why i dont use the 5ohm resistor.. to get as much as possible from the 5V input. *even with the 5ohms, i could have burned matches with 16x dvd diode i think, its maybe not as much mW, but at least...

Hey.. I'm trying to figure out what are the best and max current and voltage for 16x and 18x and 20x dvd burner diodes.. can somebody please tell me.. I tried to search it but then searching within 10billion posts, that's just insane. Btw im not using the 5ohm resistor between the pot and the...

i cant find any laser power calculator... how can i measure the laser diode power? can i use the equation "P = U * I" ? U is voltage measured in paralel with the diode and I is the current flowing in series with the diode. It seems too easy to be true to me. because that would mean that my 16x...

thanks, but i tried it anyway.. got 2.33V and max 125mA?! of current.. I used this scheme from your site, rog8811.. i forgot to buy the 4AA battery case.. so thats why im improvising with the USB. .. burns the el.tape easily and can light matches.. i dont have any balloons currently at home...

yo.. i just ordered the stuff to make the driver and i wonder if i can use the power of my pc USB connector.. its +5V which could be enough, but i have no experience with this driver so i'll be glad if you can answer me:) greetings from Czech
