ok thx is that the temperature that the ld should not go over?

how long do you think i could run this laser for in minutes. its at 300ma and has this heatsink in the picture, it is a 20x dvd ld

.

It is a DDL driver and it has all the necessary components to keep this laser alive for a long time. About the cable I can shorten it if you want, if you please you can stick the heat sink and the diode inside the hole in the case, I did not do this because of the regulations of the government...

take a look at the picture. make an offer if you would like it. i have one that is very similar on ebay http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170176751664 if you want to see that one. one on ebay is 250ma going into the diode. both have heat sinks and run off of 4 AA let me know

is there anyone that can explain the fda crap to me i dont understand everything you have to do to make them legal. i have made a really nice burning laser and would like to sell it but after i ran into info about Regulations im not so sure anymore :'( ill post some pictures ^_^

what about soldering, i have thought about what i could have done wrong and the only thing i can think of is soldering. i put solder on the wire and then let it cool and then attached to the diode as quick as i could. i didnt think i could have heated it to much because i touched the wire to...

ok thx

thx everyone for your help i just am upset that they are dead :( i was so excited. i just saw this and wanted to post it, could this be a problem, it looks like it was hammered in to the case, or could the USPS have droped the package and killed them? i have a ton of respect for you guys...

i really appreciate all the help ^_^ 2 last pictures let me know if everything looks right with the readings im getting. one is volts and one is amps which the amps is in series

here is a picture of it on the wall about 4 feet away i used a 3 watt 25 ohm pot from radioshack and it is turned all the way up also the laser diode does get pretty hot in about 5-10 seconds or so what do you recommend me doing? i can take a picture of the circuit board if you want it might...

yes i can focus it on a wall about 4 feet away.  i tested the 250 ma's with out a diode through a tester which acted as the load.  i have 2 10 ohm resisters in parallel and i started with the pot very low i would say about 50 ma and then turned it up and it just got a little brighter.  i am...

Hi, this is one of my first posts.  I love this forum and everything about it, the people here are great.   So here we go, I built the driver by DDL and I have tested it probably 50 times lol it sends 250 ma through it and the volts were normal sense I did not have the laser diode yet.  I...

Does anyone know how to make one? It would be a very helpful instrument for the tuning of my lasers
