Just a little note about round vs square drivers. DO what you want but consider this.
Many of those making requests for round drivers are from newer members only on a few months.
It might serve you well to Go with what the veterans are asking for first. They have been on here a...
All excellent points, but the one I think you missed was also the price.
You can build a very nice lower power laser pointer, in most colors, for much less than the cost of the high power AND without the added cost and additional issues with chopping the power back.
Its not usually worth the...
You can more easily use flashlight hosts to replace parts with laser diodes than using laser hosts and swapping parts.
Try fasttech.com for some at dirt cheap prices - but the ones that work best, are usually not the 18650 bodies unless you machine a heatsink for it.
The Triple "A" or 10440...
Not trying to be mean, you have a valid point suggesting they introduce themselves first and you post that on every member who doesn't.
I don't know my exact wording, but it should have been, "hakzaw does not it like when members do not first post in the welcome section". That was the intended...
3 probable possibilities already stated! BUT without at least knowing the color and type of diode its impossible to tell. With that driver it could be a lot of different diode combinations.
1.as stated it could be a non-neutral case diode
2.as stated it could be a battery connection
haksawz doesn't like new members that don't post in the welcome section first.
What are you looking for, I may be able to point you in the right direction. Do you have laser goggles? Needed if you are working with anything in the 10s, 100s or 1000s or mw. So you don't burn up your eyeballs.
If this is the one you have:
DTRs' website, tells you; you drive it with 2.5-6.0v and something that will handle over 1A current. Read the heading for the one you bought.
Which means any SINGLE decent quality 18650...
Thank you for the pics, always nice to have again - I appreciate that. Locking the aixiz lens like that is great idea.
I had seen something in the past with a couple steel rulers and an enclosure also, sticks in the back of my head. Just trying to get ideas, I just picked up a 10x expander...
Not sure, but with the wiring like it is and not knowing, I would definitely have someone else in the room nearby just in case you light up, especially if it is some form of a leiden jar.
Wish you the best.
