ArcticMyst Security by Avery
built my first DIY OC red but...
- Thread starter AjentX
- Start date
also no plastic no marker.. (dont have any balloons to test atm..) also im running it through a rckstr with a 9V batt.. (brand new) and it heats up in my hand in less than 10 seconds.. (so hot i cant hold it anymore (the driver and the module)) its also not in a host yet..

u probably already killed it at that current.
what driver are u using ?
it should easely burn any black plastics

9v, abit to much, go for around 6 - 7.2v ish. Also, is it in a heat sink, getting hot like that, sounds like its not. Ya might of burnt it out.

As long as you are still getting bright light out of it, the diode is working.
Are you sure about the current? Have you had the output measured with an LPM?
Are you holding the laser in your hand or is it being held by something else? The human hand "shakes" when holding something steady. This movement can "wiggle" the light around enough to prevent keeping the spot in one place long enough to burn.
Are the objects you are trying to burn dark? Red will mostly only burn dark colored objects.
Most important -- are you really getting it focused? Do you have laser goggles? Without goggles, at these outputs, it is impossible (and very dangerous) to see the actual spot of light. The bright "blaze'" of the light will cause you to "think" it is focused when it is not.
Peace,
dave

dont have one :/
yes im holding it ill try using something next time..
yes they are all dark (or made dark w/sharpie IE the matches)
its not very blinding.. i mean i can look straight at it.. (not into the beam or anything.. at the spot..) so i guess it maybe LEDed.. :'( ill try to upload some pix a little later today..
also i am using a rockstar driver.. i had it set at the lowest setting and it was still giving me about the same output light.. but i did measure it all before i put the LD on and it was reading about 130mA i ran it at that for a while and then slowly turned it up to 430mW and it did nothing all the way :/ it also stayed about the same bright.. it is also in an aixiz module.. i dont think thats a problem but hey its my first build so i guess it may be..
thank you all for the help..

If there is a "ton" of light coming out of it, it is NOT an led. When diodes go LED they are usually around 5mW. Is your lens messed up? Can you see light through it clearly? Can you see a clean reflection of the light in the room off of its surface? Is the back cut out of it?

[highlight]**EDIT**[/highlight] I have to go to class. I'll check back here in the afternoon.
7.2V is ideal. It looks like your diode isn't pushed in the module completely, because that could prevent you from being able to focus it (the distance from the diode to the lens). It looks like you still have the little "circuit board" attached *Don't press in the diode with this attached because it will force the pins inward and destroy the diode. Plus, the diode needs to be perfectly straight, and not crooked in the module (the "hot spot" needs to be directly in the center)
Are you sure you're giving it the right current? I don't think a diode will last very long at 430mA.
Edit: you're using a 9V right? Is it fully charged? I don't like 9V's. May be providing the correct volts but not current

i only left the little thing on it because i already destroyed one OC last night trying to take it off and this was my last one :/Ace82 said:
Edit: it may not be in all the way as well.. i did vice it pretty hard but i didnt want to break anything.. (this is my first lol) and i didnt know how much pressure they can stand..
in the photos and for now im only running at ~130mA and the hot spot is A LOT smaller than it looks in the photos
yeah its as fully charged as they come
.. and i did measure with a dummy load before starting and it was running at 130mV and at 430mV (thats measured through a rckstr DL) so it should be just about right on..

Dave mentioned this but as you have not said anything, have you opened out the back of the lens nut?
On the voltage thing if I remember correctly
Red LD 3v + overhead to operate regulator 2v + max over-voltage for Rkcstr drive 2v
Total 7volts, you would get away with 7.2v

i dont know what you mean by this..rog8811 said:
-[ sorry new..)i thought with a rckstr you could use like 6-12V or something like that so i just grabbed a 9V because it was convenient and its easier to hold it on the leads than say a AA or something of that nature..
