Well, maybe collimation wasn't the right term to use.
You know how the beam from a common 445 will tend to diverge more than one from a single-mode LDs due to it's larger emitter?
Removing the can seems to increase that effect a good bit.
Well, the drill method worked pretty well for me. I used a single-edged razor blade to make the cut.
I first practiced on a 445 that was LED'd, and it still lit up afterward.
Then I did the same on a 445 that had a smudged/scratched window. Beforehand I measured 890mW from it. Afterward it...
I assume that the idea is to weaken the metal, but not actually penetrate it with the blade (and thus not contaminate the semiconductor with metal dust), yes?
I suppose I should just try it. I have some that are truly dead that I could use for practice.
I apologize if this has already been covered somewhere I have not yet looked.
I have seen a number of posts talking about de-canning laser diodes, but not much said about the actual process.
I have a number of LDs laying around (mostly 445s and 405s) that have damaged cans or windows that I...
That's the essence of it.
A flexdrive measures the amount of current flowing through it, and will adjust it's output voltage up or down (within it's limits) as needed to maintain a constant amount of current.
A laser diode will consume all the current you can feed it until it fries, if given...
I once used a pair of laser pens to preserve the alignment on my wife's car while I replaced the outer tierod end.
I used zipties to fasten them securely to the two front wheels (in retrospect I should have instead attached them to the brake rotors), and placed pieces of tape on the house and...
I've always bought the TrustFire 18650s from DX:
$7.88 - TrustFire Protected 18650 Lithium Battery (2500mAh 2-Pack Blue) - Batteries
So far, out of 6 or 8 cells, I've not had any problems.
That's quite a good price you've found.
Here are the UltraFire green 2600mAh rated ones on DX:
Nice. I just made a working MicroBoost yesterday from two dead ones. I had operated one with no load accidentally, and after 5-10 seconds the large resistor had cooked itself and cracked in half.
I transplanted the one from the other MB that had other problems (made too much current for some...
I see there are some 16X BD-R drives around now...
I wonder if the diodes used in them are any better than the 10X/12X ones.
It looks like it might cost $279 to find out. :eek: :undecided:
Edit: I fail. Looks like this has been covered already. They're not 16X BD-R writers...
Doh. Sorry about that. :oops:
Tell you what...I'll offer to sell you guys any that I have in stock for the same cost as you would get ordering from Lava's webstore, on an ongoing basis.
I don't have much to offer at the moment though. I have 5 FlexDrives left, and 8 of the P3s.
The FlexDrives have been unavailable to purchase from Lava's webstore since at least 3/10, and the MicroBoosts for longer.
I made an inquiry on 3/10 to ask when they would become available again, but have not received a response.
I thought I would ask here to see if you guys have any intel on...
