I'm always in for more power in a smaller package. :beer: Don't know when/if it will hit the streets though. Snip: "...The new ionically-conductive cathode enabled the ORNL battery to maintain a capacity of 1200 milliamp-hours (mAh) per gram after 300 charge-discharge cycles at 60 degrees...

...MULTIPLE times!:yabbmad: I decided to post this thread in General because I figured it might get the most views here; mods feel free to move it if/as needed. This happened in the same town where I live. I do not know this individual. This kind of idiotic behavior by laser owners is only...

Searched but did not find an answer to my musings: Has anyone ever built a host with heat pipe(s) built into it to increase heat flow... say to help carry heat from the front heat sink to the handle portion of the host (and thence into the hand)? Or, might there be a way to build a host that is...

Thinking of some new uses for my Tesla coil now...:D Snip: "...The team used an ultrashort-pulse laser of modest energy to make the laser beam intense enough that it could focus on itself in air and stay focused in a filament, he said. “If a laser beam is intense enough, its electromagnetic...

Yes, I realize that silver is far more expensive than copper, but has anyone considered or used it for a heatsink, especially for small/micro builds, seeing as silver has several percent better thermal conductivity than copper? A common one troy ounce silver round currently runs around US$32-34...

Thought I would post the link to this list that gives thermal conductivities for various metals/alloys. Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat - Engineers Edge fyi, T.

Over in the Red laser section Milos posted a link to their 1W red. Does anyone know anything about LaserTo or has anyone ordered anything from them? If so are you happy with it? TIA for your input. Teslanium (formerly the poster once known as Ragnarok ;-) )
