[QUOTE=MacD11;34132741]That's no good if your gonna be hosting LAN parties to go, because how are you going to maneuver easily with a keyboard that small?[/QUOTE] Well, there's always Deltaco, this 30 cm long keayboard costs about 10€: [img]http://www.kauppasatama.fi/tuotekuvat/big/tb-191.jpg[/img] Then again, I'd need a mouse of some sort.

[QUOTE=TehWhale;34133486]it doesn't have enough ram to run a desktop environment, you don't need a mouse[/QUOTE] you'd be surprised what Linux is capable of with low specs
okay let's put it this way, you don't need a DE
[QUOTE=Protocol7;34128615]I speak for quite a few people when I say SD basically implied MicroSD because every fucking thing that uses expandable storage uses MicroSD and I don't know anyone who calls it a MicroSD card in everyday speech[/QUOTE] You can just buy a micro with an adaptor, though hell everyone uses that instead of a normal sized one nowadays
I've got an old korean made emachines keyboard from around 1999 that I'll hack up for this thing.
How expensive/bulky are VGA to composite or HDMI adaptors?
[QUOTE=latin_geek;34133911]How expensive/bulky are VGA to composite or HDMI adaptors?[/QUOTE] vga->hdmi is bulky, requires power, and cost around $40 each. VGA to s-video or composite each cost around $3, take up an inch of space, and don't require external power.
I'll probably get a BeagleBoard instead, but this is a very nice idea.
I had always thought of a "splitted" keyboard, actually two keyboards, left segment and right segment, they would join together in a cable somewhere, they would be supposed to be clipped to your belt and operated with your hands resting on the keys, a free thumb could operate a mouse ball. Then, give it a nice very durable lithium battery. Play Quake while walking home, all day. Or program, whatever you want :P
those aren't nerdy or hip, they're just straight stupid

I can imagine having one of these, it would rock so hard. Lego (or wooden. ain't having this thing clatter around unprotected) case, roll-up keyboard (they sell them, a tad unresponsive but they're waterproof!), wireless mouse. Usb octopus of course, and I'm pretty sure they sell micro monitors. What to do about power, though? I guess you could tote around a phone charger and usb-to-wall plug, but a battery would be more convenient.

What about using a small solar panel?
[QUOTE=eagleeye64000;34135170]What about using a small solar panel?[/QUOTE] that could work but I don't see how you'd get a constant 5V with it
[QUOTE=ButtsexV3;34135118]I'm probably gonna just gonna carry around a few 9v batteries and a voltage regulator.[/QUOTE] That sounds solid enough. How easy would it be to "string" the computers together? 2 model B's would be nice and cheap and have more oomph than a single one. I doubt I'll be able to buy one in time, the price means they'll probably sell like hotcakes.
[QUOTE=ButtsexV3;34135206]that could work but I don't see how you'd get a constant 5V with it[/QUOTE] Have the solar panel connected to a rechargeable battery.
[QUOTE=ButtsexV3;34135118]I'm probably gonna just gonna carry around a few 9v batteries and a voltage regulator.[/QUOTE] Why not a [URL="http://filesmelt.com/dl/7805datasheet-730100.gif"]LM7805 voltage regulator circuit[/URL] and a [URL="http://stores.ebay.com/All-Battery-Center/AA-/_i.html?_nkw=2600mAh&submit=Search&_fsub=7374239&_sid=75872916"]couple of these batteries[/URL] in series? That would give you a circuit with a stable 5 volt output with up to 1 ampere. And the batteries should give you enough time. Eventually a hybrid parallel & serial battery setup would yield more battery time.

toss it in a project box and you've got yourself a little media center.
[QUOTE=ButtsexV3;34135648]distributed computing isn't too hard to set up but it's not like you think it is. you can't just expect doubled performance across the board. the software has to be compiled for distributed computing.[/QUOTE] Yeah. I'm gonna have to do some research before I buy one, that's for sure. I've pretty much used Windows my whole life but I'm willing to learn Linux. I still don't really know what to do for a portable display...
[QUOTE=Strider_07;34135685]toss it in a project box and you've got yourself a little media center.[/QUOTE] I had planned on making a pandora-based radio with it to have installed in my car. I'll carry around a 3G hotspot for it and shit will be fancy
This thing would be cool to stuff in an old keyboard, maybe with a battery pack. and maybe an LCD screen. Might as well buy a laptop, then..
[QUOTE=Lyoko774;34136099]This thing would be cool to stuff in an old keyboard, maybe with a battery pack. and maybe an LCD screen. Might as well buy a laptop, then..[/QUOTE] Where's the fun in that?

[QUOTE=latin_geek;34136382]The prices defeat the purpose and there's no drivers for the screen, but that is a cool idea.[/QUOTE] I agree completely about the prices. How would you go about salvaging a keyboard from, say, a dead Smartphone?
[QUOTE=ewitwins;34136409]I agree completely about the prices. How would you go about salvaging a keyboard from, say, a dead Smartphone?[/QUOTE] You'd need to fabricate your own custom controller, or retrofit one from a cheap USB keyboard to work with it.
[QUOTE=Van-man;34136435]You'd need to fabricate your own custom controller, or retrofit one from a cheap USB keyboard to work with it.[/QUOTE] Getting my hands on a cheap USB keyboard would be a piece of cake, and I have a decent amount of experience when it comes to electronics soldering, but I have no idea what goes to what. Are the connections in a phone keyboard different than those of a regular keyboard and, if not, do I need software for the symbol shift button?
