Two perfboards, about .3 inches apart, with a 20 pin header on each.� It “plugs” in a breadboard right across the slot.� On the board is a PIC18F452 with a 10 MHz crystal, required capacitors, and resistors.
Now, I can’t decide if there would be a ZIF socket or an ICSP header.� I should figure out ICSP.
Imagine this. An ergonomic keyboard with a smallish LCD under the spacebar. It is powered by a few batteries, and has a backlight on/off switch, and a regular unit on/off switch. It has an SD slot, and a USB port.
You type, it shows up on the LCD. � You can save to different files, having one for each class.� You can open other text files, edit them, and save them.� There may even be space for a game or two :-P.
It saves the data on the SD card, and you can download/upload data just like a thumbdrive.
Total cost for a single unit? Less than $50 dollars.
With an RFID hand implant, and a special mouse, you could set it up so only your hand would make the mouse move, or even shock a user who keeps moving it without the implant.� The keyboard could also detect your hand.
An interesting project to investigate would be a bluetooth subvocalizer, like the things the SEALs use.

Most people who know me know I’m absolutely in love with wearable computing. I’m in love with it to the point of wanting to go to grad school to work with them after I get my Electrical Engineering degree.
It recently came to my attention that I may have nearly everything needed for a good step in the right direction.
The ideal wearable is modular, as the equipment available changes all the time. When I’m sitting down at a trusted computer with my wearable, I don’t want to rely on a tiny display or auditory output. I want to be able to interact with my data on the dual 19 inch LCDs.
I need to be able to
ON THE GO!
Now, there are a lot of reasons why it’d be good to have a head-mounted display that lets me see some computer output as well as the real world. However, there are a lot of reasons why that isn’t going to happen in the next year or two for me. I don’t have over a thousand dollars to spend on a display. This limits my options a large amount. I also don’t have the knowledge of optics required to homebrew a solution based on a cheaper display.
Gargoyles represent the embarrassing side of the Central Intelligence Corporation. Instead of using laptops, they wear their computers on their bodies, broken up into separate modules that hang on the waist, on the back, on the headset. They serve as human surveillance devices, recording everything that happens around them. Nothing looks stupider; these getups are the modern-day equivalent of the slide-rule scabbard or the calculator pouch on the belt, marking the user as belonging to a class that is at once above and far below human society.

I was able to get a TI-89 on my desktop fairly painlessly using Wine. Years ago, I owned an 89, but it was destroyed in a tragic high school chemistry lab.
Now, I can do my homework with the same hardware I’ll borrow from my roommate to use during the test!
