Looking back at the computing lessons I had in secondary school, I learnt a lot but I think that having access to something like this would have been much more beneficial than using Access and VB6 for coursework (in 2007).

I hope they can actually get the cost down to something close to the £15 they say. Good luck to them.

I'm confused - he said its good for children who might not have a computer at home, but there is only an HDMI connection. What is the likelihood of a family not owning a PC - but does own a TV advanced enough for HDMI?

I think you'd be surprised how advanced and expensive some people's home entertainment systems are compared with some other parts of their lifestyle.

If you look at the actual site (http://www.raspberrypi.org/) it mentions Composite and HDMI video output under the tech specs.

Thanks for pointing that out. I think this is a great project and hope it takes off. I would definitely buy one myself to play around with.

Earlier quoted context omitted.

USB hub, perhaps? They appear to be using one with many devices connected in the photograph on the official website [1]. [1] http://www.raspberrypi.org/ubuntu.jpg

If you need a USB hub to use one effectively, then the true price just went up by a third or so. Why not make the thing twice as thick, providing room to add an ethernet port and a second USB port? Then much more of the associated costs will be incorporated into the unit.

I think "effectively" is really dependent on the end user. If the goal is to provide an easy and cheap system for school children to work with, much like the OLPC, then internet may not be something that is available or required for the target demographic. In the case of your standard hacker, it would obviously be awesome to have all the additional items on-board, but with the ease of adding a USB hub and all required additions to it you can expand on it as much as you want in what ever cost range you can afford.

"In some ways, the project resembles the One Laptop Per Child (OLPC) scheme," "The volunteer team has to produce a better working prototype, has to show that it really can be manufactured for around £15," So yeah, it really IS like it... Especially in that their stated price won't end up being what they sell for in the end. At the $25 stated on their homepage, I'd buy a few of them for playing with... Well, if it had…

Fortunately, URB-to-Ethernet adapters aren't very expensive.

Or USB->WiFi.

The mini-USB bluetooth adaptor that they currently have stock of in my local pound shop (for, not surprisingly, £1) (they look very like http://cgi.ebay.co.uk//300388440707 so may be the same thing) work perfectly will under Ubuntu (at least on 10.04 and 11.04). So as long as the bluetooth stack doesn't eat too much of that small chunk of RAM and network speed is not a big issue you could use the PAN or DUN profiles for networking on the cheap, tethering to a phone or a desktop/laptop with bt and PAN/DUN support.

The official site doesn't say anything about power but as the image only shows USB and screen connections I assume it runs off the power a USB connection can provide, so it could probably run nicely off a pair of AA or AAA batteries. I can think of a number of play projects for monitoring (attach a cam, mic, temperature probe, and so on via USB) or display (attach a small LCD screen and/or a beeper and you've got a portable status monitor for some other project).

Something like this could be great fun for a nerd like me to spend a bit of time playing with. A bit like an Arduino for a software-only person. If they do hit the market at the £15 estimated or there abouts I'd certainly buy a couple, as I'm sure would a couple of my friends.

Absolutely agree. I help move some of the poorer families at our church, and I'm always astounded at where their money is spent. One family wore hand me down clothes and had little else in their house, but they had a 60"+ TV in their living room.

Most families have a TV, and just about every TV you can purchase these days has HDMI. I'm incredibly sad when my teacher friends describe how few of their students have computers at home to do their work.
