btw, i used a battery solder to solder the piece of nickel sheet on the driver to help make contact, it was poorly contacting before. Is there any risk of this type of soldering in the future? The "burned" part in the last pic looks bad, but its actually just surface level, more so on the sheet.

its probably a sharp 480~488nm laser, i think 150mw up to 200mw is fine? I want to minimize effort, if i don't have to change it, i prefer not, as I have to figure out how to open or get that diode out and secure back whatever... but if its easier, such as i can buy something that i simply...

ok, i opened it and the driver appears burnt, and while messing with it, one of the wire fell off the driver. i guess i need a 16.8mm step down driver to 200mw cyan (curtesy of gemini guiding me)

i may have killed the laser by reversing the battery orientation. It was originally bought from someone here over 10 years ago. I am looking to just "upgrade" it now. what will i need if i have host and want to change out the driver, the diode (maybe still good?), and what else? would...

ok, i sort of fixed it. the set screw was actually to hold the diode piece. the lens screws on to that but is meant to be adjusted. however, its diverging so much (seems like more now than before) and its very difficult to get an "infinity" focus. It is very high power, so it burns easily...

i managed to pry the board open, but inside it looked to be epoxied. and the fine thread, i think they aren't threads but just machining marks. its very very fine. and i am pretty sure its one piece. however, the "this may also be a union" is probably a union that's epoxied too. as for...

Yes that's exactly the set screw to hold the focus. it's loose over time and due to dropping. I didn't know the focus fixed and tried to turn it and made it looser over time. hence my sharpie spot. now the diode is also loose. not sure how to open the whole thing to fix. Sorry I really...

ok, i think i found the issue. when i shake the "head" something is loose... not sure how to disassemble it further to fix it. but i am guessing the diode is moving around therefore not aligned

this is without any lens at about 2 feet

I bought a big pointer from fb back in the day. the parts had start coming loose, so I took it apart (just trying to figure out what was loose) and after putting things back, it no longer focus. I don't think i lose any lens. it is just a diode, a collimating lens in a fixed position? but...

anyone sell 2 lithium batteries in series laser? I have host, switch, just need laser driver/diode. will need help focusing too (always had issue focusing the cyan)

I am always a geek, and was into laser earlier but life got in the way I guess :D I will report back once i am able to fit it with the new g2 lens that's coming (hopefully it is true g2 since I am buying off ebay, one never knows for sure) I did notice some very light (soft?), and very wide...
