BobLaser(?) 405nm Pointer

a module which holds the diode by a retaining ring?

which means you can realy simple onthefly excahnge it without pressing tools?

interessting... moar pix!

heres the catch. After you unscrew the retaining ring it is still stuck hanging loosesly on the diode pins between the diode and the circuit board. You can easily desolder the pins from the circuit board and remove the diode, retaining ring, and circuit board. When you install a new diode you need to either solder extention pins onto the small pins from the new diode, or just solder on wires. If you choose wires, you are going to have to come up with some way to stablize the circuit board so that pressing the button will not push it down. I extended the pins when I did a diode swap and it worked fine, I added epoxy to hold the board super stable just in case. I have one now that is doing over 200mW with a diode swap. I also adjusted the focal point so that it will be focussed at like 10 ft. This still gives me a nice dot for distance.

Dave can you measure the current at 100mW please? I'm modding one, and at the tailcap I'm getting 370mA, while with my lavadrive kryton set at around 110ma, I get 170 ish. At these currents, the boblaser one is nowhere near as bright as my kryton. Could the higher power be something to do with the efficiency of the drivers?

this sounds interesting. Is there any lower diode than the ps3 one?

 

[robjdixon]

Ok now I'm at 270mA, and it is brighter than my 100mW kryton. Also, the beam is much narrower, so the optics must be great!

hi guys i got my 80mw also from boblaser .. do you think i can modify it too?

Hey Day do you have any of them left? I would like to play around with one

you can order from boblaser it very cheap though
