    Finely focusing a handheld laser (NUBM08)

    I just bought a NUBM08 9mm. Mostly seen these bought these(picture), then the diode died. I don't have lpm so temp time by comparison is unlikely accurate. I could sizzzle wood as it burned violet. So naturally i ordered a replacement diode before i owned a caliper. I'm asking necessary how and...

    How healthy are your batteries? (How to measure internal resistance)

    So, regardless of both batteries being of the same brand type,chem, amp rating, weight at point A, somehow the - terminal leading battery is -0.44 V defeciencient from the same battery behind it!? Any ideas please? Too high turnage on current flow potentiometer value. Doesn't explain the decency...

    How healthy are your batteries? (How to measure internal resistance)

    I place a GTL 14.02 G IN BOTH BATTERIES in series in my last part, however my front door toward diode is rated out of the chamber after the fact, has 2.86v (front most battery) 3.62 backmost battery. Rear battery 3.88V same brand, only used together. Any feedback would be greatly appreciated...

    IS ANOTHER GOOD BATTERY CAN BE BETTER THAN ultrafire?

    I don't know I'm the only one here that consistently weighs his batteries on 0.00 g scale, but my first pointer came with two LC 16340 ultrafire 3.7V 1200maH. Now one weight 17.93g the other one weighed 14.63g. I found a solution that maxed the batteries without overcharging at all. I use an...

    New laser beam doesn't follow traditional laws of refraction.

    So my first post, I thought this was pretty interesting. (It's in the Google main page news feed, [***edit, c0ldshadow adding the link for Zerosage since he didn't have access yet, https://phys.org/news/2020-08-class-laser-doesnt-laws-refraction.amp )***] I'm not gonna pretend I totally...
