$2.50 Diode. (10x) (Single $3.50)...
Fooling around with some old LOC reds and some of the $2.50 reds off Ebay. I didn't want to spend for a pricey driver. SO, here is the minimum AMC7135 driver. It will give 350ma on a 10440 AAA or any single cell rechargeable. It doesn't need heatsink and although the diode will get warm after a...
Back in 2014 there was a great host produced in a group buy. I bought 3 of them and a few others did also. I haven't seen one single laser from this host online. I also haven't seen any revisions or subsequent group buys.
They had a massive Copper heatsink and were designed for a single 18650...
Hope this doesn't violate any rules on here, but There is a thread over on PL with a number of items for sale.

What caught my attention was the 594...

I'm looking for a driver that meets this spec. Preferably without going to a $20-25 Flexdrive on a $3 diode

Well this is Post 1000!
I am sure I hold the record on the SLOWEST time to reach 1000 posts. But that just means I have a longer attention span than most.

Yesterday and today there were lots of news items in various lectures.

1. X-Lasers new driver Up to 5 amps. Not for handhelds, 2v overhead needed. Should be out in next couple months. Perfect for labs and Projectors

+4mw 612nm HeNe
At last years SELEM, I pick up a SP-127 from Mariomaster and brought it home, it's doing about 40mw and very happy. I run it about once a week or every other.
A few months later I was watching on...
OK, if you've seen the latest Big bang theory. At the very end they pop a ballon with a laser.
I'm thinking it's bogus the way it's presented.
They have a laser breadboard on a cart with a power supply, and two wires running to a head. Definitely looks like a HeNe.
It puts out a green beam...
Am I the only one doing this.
I'm all hyped about the Lasos I'm picking up this weekend. So I got all my lasers out (other than handhelds) and started turning them on.

11-9-11 I fractured my thumb in a hit and run accident. I've been out of work since and finally got back to work this past week.
As a result, I've spent some time to try and clean up some loose ends on various forums I'm on.
Kenom owes me over $200.00 on this forum for beasts I have paid and...

Here is one of the Argon 40MLA lasers I picked up a couple weeks ago.
Still trying to get the other one to work.
