Wearable Computer

Intro

This is my attempt at a wearable computer. I'm on a very limited budget, so many things revolve around that deficiency. This is a good thing, though, as it means it could be relatively easy for others to follow suit.

Ingredients

Hardware

Desc.Specs.LinksPriceNotes
small laptop computerFujitsu Lifebook P-2110) running Debian GNU/LinuxCrusoe's site$1400-$2100This is an excellent full-powered laptop that gets a good 8h of battery life in practice, doing normal things (including wireless)
carrying bagTarget "Get into the Game" bag. Apparently mfg. by CaseLogicLeoG.net discussion$20This bag is designed for a playstation, but fits the lifebook just dandily. This is hard to find item. See the discussion for details on how to find it.
Laptop backpackTimbuk2 Detour bag$100A rather large bag that holds the laptop, all the accessories, and some other useful extras. I'm very fond of it for its backpack straps, as it will let me bike with it and not worry about it falling into my lap. The load is also more distributed than with a single strap, so I don't have to worry as much about my back's health.
One-handed wireless keyboardFrogpad BluetoothFrogpad websiteFrogBlog users' forums$225 or lessGood for functioning as a full keyboard for wearable applications, however a bit too bulky to wear on arms or hands. Could easily be put in pockets, though. Works with a stock ≥ 2.6.8 kernel.
USB GamepadGravis USB GamePad Pro 10 buttons, 1 8-way directional$15Any gamepad with lots of buttons will do. This was simply the cheapest.
Bluetooth GPS ReceiverHoluxGPSlim 236Semson Inc. - the Yahoo store where I bought mine$149

I've been looking for a good Bluetooth GPS for a while now. It seems I've finally found one of the best ones.

This is tiny (a bit bigger and wider than a Zippo), works easily on all my devices (Linux laptop, Palm, Nokia cellphone), has simple status LEDs, charges off USB (and you can apparently get data from it using USB, though that seems to require a special cable), and has a removable (and potentially replaceable [looks like a Nokia cellphone battery]) rechargeable long-lasting Lithium-ion battery, and an antenna port. Yeah, it's got everything and is still minimalistic and small - perfect.

Headphones with Boom Mic$80ishOK, so this isn't necessary, but could probably let you use some voice activation of things.

Software

Linux
Or some OS that can run all the below software. I chose to use Debian GNU/Linux as it's my operating system of choice.
Festival
A very useful text-to-speech system. This will let your computer talk in a variety of languages (OK, for me only English and Lojban).
Xmms
Plays mp3s, oggs, and other sounds/musics. Most importantly, it has a nice API for interfacing with it.
JoyMenu
A joystick-controlled audible control system. It's sorta like a telephone-based menu, but better.
