Homebrew Digital Picture Frame w/Remote

feagle814 writes "I've always wanted to create one of those digital picture frames out of an old laptop, and on the heels of a recent slashdot story, I've written up my Digital Picture Frame project. What's unique about this particular incarnation of the digital picture frame is that mine includes a homebrew remote control recognizer made out of a programmable IC, the Microchip PIC16F628. The article discusses everything from design considerations to custom slideshow software, all the way to final presentation, with lots of photos along the way."

Digital is cool and all, but when I was in boy scouts we built an analog picture frame. Man, you should see the technical specs on it, amazing.

Analog picture frame

It's a trick!

Watch out!
" I'd seen do-it-yourself picture frames on Slashdot before,"

He's trying to trick us into Slashdotting Slashdot through a link back!

Why not?

Why not just take a portable dvd player (7" for $129) and put a DVD into it filled with all your favorite pictures, then it'll display them. Then you just mount the thing in a frame.

Perhaps these aren't a good idea

Folks, I realize that digital picture frames are "cool", but may I please present another perspective?

Until we figure out a way of generating clean, renewable power, perhaps this isn't the time to be coming up with more and more ways of consuming power for trivial applications, such as digital picture frames and blowup lighted Christmas figures that run an electric blower motor all night(!) Just consider it, please.

It's just as interesting to come up with ways of reducing household power consumption.

I think you have your terms confused:

Isotopes are stable atom configurations which have an electically neutral charge, differing only in the number of neutrons.

Ions, on the gripping hand, are chemically excited atoms which have gained or lost valence electrons (according to their electronegativity) and become reactive.

This is, in fact, what makes Li+ ions useful for battery cells in the first place. Whether alkaline, NiCad , NiMH, or LiIon, chemical batteries all work on the principle that the sustained chemical reaction will produce a useful amount of electricity.

When we "recharge" our batteries, we simply apply current to the battery in such a way as to reverse the chemical reaction.

What they've done is introduced stabilizers to retard the rate of reaction, so that rather than exploding upon atmospheric exposure, the battery solution simply gets warm.
