We take access to a 110 or 220V charging source for granted. But what happens post 2012, when that pesky apocalypse thing happens and there's no remaining electrical grid to use for charging up your li-ions? The answer, of course, is a stockpile of triple-A batteries 
The "Pulse Jet", 500mW 635nm, 3x Triple-A Build
All joking aside, sometimes it's nice to have a flashlight / laser / radio / etc, that can run on cells you'd find at a drug store. Hence the "Pulse Jet" build, so named because of it's resemblance to the engine of an aircraft or spaceship. What makes this guy unique (at least in the DIY laser world) is that he runs on 3x AAA cells. Both Alkaline and NiMH work just fine, and provide him with enough juice to run full steam ahead at 500mW. Hence forward, as long as the planet provides me with a source of triple-As, my laser needs will be satisfied
Interestingly, we're often familiar with 3x AAA hosts, but almost never actually use them in that manner. I've thrown away more AAA holders than I can count. But thanks to the incredibly low ~150mW dropout of the Mosquito driver, this build is completely happy being fed by three traditional 1.2 or 1.5V cells.
Now for the photoshoot:

I seriously love this control ring. I usually keep it in medium-ish and it's so nice to turn it to high to see farther away and turn it right back to where I usually have it.
