Thanks. I actually found one recently, a DL Spartan came up on eBay and I made sure to swoop in right away and grab it. It shipped from the UK to the US without any trouble. Unfortunately it's a bit unstable. I can see it mode hopping, and the LPM shows the output ranging from ~10 to 40mW...

Thanks for your replies all. Yeah, I want one that looks consistently yellow/golden to my eyes while wearing my glasses that suffer from refraction if I look anywhere but in the center of the lenses. Back in 2012 (I think) I saw a Ghostland Observatory show where they had two laser scanners...

I've been wanting one for a long time, and the supply situation seems to only be getting worse. I've seen the 5mW pen for sale on aliexpress, but if I'm going to buy one, I really want something brighter than 5mW. So I thought I'd post here, asking if anyone wants to sell theirs. Maybe you...

I'm interested in one of these. I've sent a PM with my address.

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...

Yes I do actually. I'm glad to see that your laser hobby has developed quite a bit, judging by your sig.

Yes, the 2V range is appropriate for setting the current up to 2A. For higher currents you should use the next range up.

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: $9.72 -...

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. Planters...

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...

I know I have received a number for him automatically somewhere in the Google Checkout information several times. I have not yet been so forward as to call it.

Can you get a Money Order? I'll sell you two modules for $8 shipped. PM me.

When a wall wart is rated like this, it means that it produces ~12V when operating with a full 1000mA load. At a lower load, or no load, the voltage is often quite a bit higher, maybe even by 50%.
