Does anyone have any ideas on how to turn a digital picture frame into an e-book reader?

I've been looking around  for an affordable e-book reader but they all seem to be north of $200. While at the store the other day I passed some digital picture frames that were under $100 that were the right size and shape. The digital picture frame looks like it has all the hardware you'd need: lcd screen, media port, etc, problem is getting them to read pdf files and the like. I thought about finding a way to convert pdf files to jpeg files but that seems like a hassle to do every time I want to read something. Has anyone out there attempted to hack one of those digital frames so that it reads more than just image files?

How to strip cables to free the copper inside?

Esquire's e-Ink cover

A friend writes:If anyone is interested in hacking the E-Ink version of the October issue of Esquire, here's some info. First, it's not available everywhere, but just in major stores like Borders and Barnes & Nobel. I got one at the Emeryville Borders. They have a display rack full of them.After removing the paper, tape, printed plastic and foam padding, here's what's left: (see pic)The PCB has 6 (!) 3V lithium batteries. It looks like one poweres the control electronics and the other five give 15 volts to run the displays. There's a PIC12F629 and some pads for in-circuit programming. There's also a couple of 4094 8 bit shift registers. There are two E-Ink display panels, but they're not general-purpose dot matrix. They have a small number of pre-patterned regions that can be made black or white. If you disconnect a panel from the circuit, the panel remains in its last state.It might be possible to open up a panel and put a different pattern underneath it (say, with a PCB). Might be fun.The PCB could be useful even without the E-Ink displays. You could connect a bunch of LEDs to it and reprogram the PIC. Not bad for $5.99 plus tax.I did later tear open one of the two display panels. You can remove the aluminum backing to reveal the connections printed in cunductive paint on the back of a pattern in conductive plastic. Trying to peel the conductive plastic away from the E-Ink active layer destroys the display, and releasing a tiny amount of E-Ink dust.It does look like one could cut the display into small pieces to possibly make small separate indicators. You'd need to retain the edge that connects to the clear conductive plastic on the front of the display.

One of the first ideas came up was to use it as a fuel injector for small model airplanes. Anyone have any ideas or remarks? Btw theres plenty of companies wanting to give them away because it creates a "bond" where you need to buy the refills from them. Little do they know that I like to re purpose "free" things

How to make a robot hand without using servo motors? Answered

I'm planning to make the hand using only e-waste and this is the second reason I'm not using servo motors. (I'm from south Asia, there for it's hard to find servo motors in the e-waste.)

G.E. dielektrol capacitor making popping sounds internally Answered

I recently acquired a G.E. 40,000 volt capacitor and initially it was fine but it has started making loud popping sounds inside while charging and discharging. It sounds like there might be arcing inside but it still holds a charge just fine which is quite strange. The sound always comes from the same exact spot and the capacitance has decreased from 1.88 uf to 1.5 uf. I'm wondering if inside the cap there is several smaller ones and maybe a connection came loose during shipping but I really don't want to pull it apart because it's welded shut. Any advice on what I should do would be helpful :) Thank in advance!

I thought it would be really cool to have a small e-ink panel (low power) where the apple is to have as a clock or something. Anyone know of such a panel in color? I could just use a small LCD but E-ink has way better power advantages so I would consider that first.

How do I make a system where it sends me an alert when a wire is cut? Answered

I work for a non-profit in Mexico. We have a remote station with an antenna and computer equipment that I need to secure from people messing with the antenna on top (people taking it for metal recycling money is my main concern). I plan on putting a line or two of barbed wire lining the top of the building that houses the computer equipment inside. However, because it's so remote from where we are generally (it's on top of a hill next to us), I need some kind of remote alert system so that I know if the barbed wire has been cut. I saw a garage door monitor instructable using the parallax "Basic Stamp II" that I think I could modify for this purpose, but I figured this has been done before and their is probably a better way to do it. I thought of several ways to detect that the wire was cut, like running a small current through it so that when the circuit is broken, it sends the alert (e-mail or something like that), but I don't know how to implement that. It should be noted that the barbed wire is going to be on top of a 4 ft x 4ft building. There are no gates involved and it is a continuous wire (total 16ft long). I need to have a system that will tell me if any of the four sides gets cut. I've included a basic layout to help visualize what I'm talking about. Thanks for the help everyone. This is an awesome website.
