Not sure if everyone is familiar with the "One Laptop Per Child" (OLPC) project...but had a chance to look at one of the units tonight at the Ontario Linux Fest.

Basically the OLPC laptop is designed to be used by third world school kids in remote areas where there often isn't any plug-in electricity available. The plan is to sell them in large quantities (100,000+ at a time) to education ministries so that they have the economies of scale to keep costs down...in the $100-200 range per unit.

The machine runs a variation of Red Hat Linux, runs on an AMD processor, uses a flash drive instead of a hard drive, and the internal batteries can be kept running using a hand crank...like many of those "emergency radios". Also it has built-in wi-fi.

The screen can be adjusted so that it can still be seen in bright sunlight. It's also quite physically small.

There's more information at the link below:

One Laptop Per Child Project (http://laptop.org/)

Looking at the unit, the thing that ran through my mind was that this laptop would also make a terrific ham radio laptop. It would be great as a logging computer on Field Days, for "rover" stations in VHF/UHF contests and multi-county mobile stations in "QSO Party" contests. It also might be a good notebook for dxpeditioners in remote locations.

It could also be useful for emergency digital communications where there isn't any commercial electric power available.

Most ham radio software is quite "lightweight" and doesn't really require alot of computing power. The OLPC laptop could very well fit the bill.

Initially the plan was for OLPC laptops to only be made available to government education departments and ministries via these "mass purchases". But apparently there's a plan to make these things available to the public sometime in November under their "give one get one" programme.

Basically you buy two machines. One comes to you and the other goes to a third world school kid. If I recall correctly the price is around $400.

Don't know about OLPC - How long will it run on a windup?
But check out this one - size of a paperback book and runs a full day on 5W:

Supposedly costs $285 US (probably plus monitor). Includes gentoo preinstalled! Allegedly will run ExPee too, but I'll bet it crawls with that.

Not sure off-hand, but the person who was doing the presentation had it constantly on last night and it seemed all day today too...so it does seem to last a very long time.

Got a better look at it today...and there is one thing that it is lacking that hams would like...namely serial ports. Just has USB ports. So you'd need a serial to USB adapter for some ham radio applications.

I did take a few of my own photos with my cameraphone...once I figure out how to get "moto4lin" working, (Linux software that allows your computer to talk to your Motorola phone), I'll post some photos up on my website (providing the photos are any good!) http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif

BTW, ran into quite a few local hams...including one of the presenters at the Ontario Linux Fest.

One of the other things I think I remember reading about this laptop is that you can use them to make an Ad Hoc network or link them like repeaters to share internet between them.

That would make them cool in and of themselves.

Yeah they can be setup for wireless mesh networking.

In many third world countries where textbooks are incredibly expensive, a teacher could just zap a .pdf file around the classroom.

On Field Day, or for emergency communications...or a multi-multi contest station you could just zap info around on the instant wifi network.

It has to have a serial port to be a good "ham" computer(in my opinion), I know you can get the the usb to serial dongles but its nice to have one built in for convenience.

You just haven't done Field Day till you've done it with a hand cranked "Command Set" generator. http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif That's a full-time job!

I imagine the hand crank jobs work very well for those laptops. I'm also SO glad they're using Linux...this might be the final nail in Microslop's coffin. http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif
