Journal Journal: Flashlight Modification - From CFL to LED

My old Coleman 5324 CFL lantern had the bulb die (ballast still good.)

However, I did not want to go back to the horribly inefficient CFL it used.

So I slammed in an MK-R LED with a heat sink.

This weekend, I'll be making a test video from the top of the nearby mountain. I'm going to try to spotlight my camera at my apartment while atop that mountain, and compare it to other light sources, like the LED on the iPhone 4S.

".except what we find out is that actually you only have just enough knowledge to look stupid because you overlooked important details such as the obvious limitations imposed by having your radiator mounted directly on the device being cooled."

Yet you'll gladly stuff that radiator INSIDE THE COMPUTER CASE and cause premature heat failure of other components inside, like your motherboard.

BRILLIANT!

"What's so great about an operating system that was invented before the age of Dropbox and Facebook, an OS that's almost as old as the original Google search engine?"

It does everything newer operating systems do, with a smaller footprint, and without so much goddamned annoying DRM.

Only exception? No support for anything higher than DX9. Which isn't important for anything but gamers.

Of course, the same could be said about Windows 2000.

>You circulate the water between the heat-producing surface and a heat-dissipating radiator.

Which means you still need air contact and air flow to cool off the radiator.

So you just waste more power on an already inefficient cooling process.

Might as well be a fool and use a Peltier inside the computer at that pint.

Only to still replace it with air cooling further down the line. What a waste.

I design cooling systems for high-heat semiconductors. Guess what? Liquid cooling SUCKS as you're still limited by how fast you can transfer the heat to the air ultimately.

Direct metal cooling, or phase change. Liquid/water cooling sucks.
