Pen Laser Thread

Yup, that's the one.
Didn't know they had stopped making them

Hi,
Does this count??

Looks pennish enough to count. What is it?
I'll need to look back through my stuff and post a pic of the pens I still have at this point.
Is there any companies still making nice pens still? Sounds like laserbtb is done with them. Too bad as there were a couple I wanted to get still. They originally sold ones that had some decent output and slowly dropped the stronger ones. Almost every pen I bought from them could put out way more than rated especially as they were very voltage dependant. Output would dramatically increase as you went from 2 alkaline to lithium to single rechargeable lithium 4.2V with spacer. Never blew a diode so they could be pushed pretty hard.

That's because the driver wasn't a constant current driver, but a voltage regulator. I've run into it a lot with cheap Chinese drivers. I have bought several only to find they change current with every setting on a dummy load.

You can still get the old btb pens from skylasers. They're more expensive there than I remember BTB having, but they have them

We need an updated snapshot of Dr.lasers pen collection too , looking at his sig I'd say it would have to be the best collection of CNI glp's on the planet !!!!

Who did you sell it to? Maybe sometime soon I’ll have one that looks identical :crackup:

Hi Richie,
Sorry can’t say confidentiality.

Took a couple of pics of my Radio shack lx1000 but have to figure out how to post them from imageshack again since I haven't done it in so long.
Story behind it is the one on the left I've had forever from my dad but it stopped working. A few months ago I was helping him go through some stuff and came across a good condition one that still works

Old non-working on left.

Haven't measured it but I'm pretty positive it's under 5mW.

 

[paul1598419]

Cool. It looks like it's all coming back to you.

The big deal about those.lasers is how old they are and still kicking (well at least one). I should grab a shot of the pens I still have....

What I would consider my nicer pens although I have a bunch of others that probably should be in with these. Think I need to go back and look in my other cases.

That be my cat "Scratch" He loves them more than I do

The cat pic hasn't been tweeked. His eyes really reflected that much.

Here's most of the rest. Same pic as a couple posts down. Some of these should be in the other case.

Hi P,
Nice collection you need a nice large Aluminum case to put all those in. Oh i see the cat has 589nm eyes what driver did you use ?? If you need a case that will fit all in one let me know..

Rich

 

[Pman]

I just found most of the rest of them and some deserve to be in the other case. I say most as there is likely another1 10 or so around the house.

Thanks for the offer. I have cases and in fact have extras from when I sold so many duplicate lasers I had awhile back.

I would do anything to have a collection that big.
Very nice I might add
