my nephew wrote this to run on my ardino thigie..... but it doesen't work....

digitalwrite(3, high)

puts power to pin 3 on the board turning it on, low turns it off (there's an led attached to each one)

right now.... it just runs through turning all the led's on every time ?

it's supposed to count up in binary 


(p.s. my little nephew write it, which is why it's pretty simple, no loops etc.... i told him i could fix it but it's been years cince i did any c, now I'm lost!)

Perhaps you could do a guide on the Arduino, I've been interested in them since they have came out but thought it would be far beyond my ability, I could see it becoming useful if you could hook up some relays and have it monitoring inputs, movement sensors and the like

Or maybe I could stop being so lazy and actually read up on them!

that's freekin awesome, let us know how you get on

Nice work, do you have to build the cube, or do people sell them?

Don't bother with a plain old arduino mate, get a nanode. They're great, arduino based but with onboard ethernet or wireless (not 802.1 though, they're xbees I think.

My main toy of choice though is the teensy 2.0 again arduino based but tiny.

That is pretty awesome - I'd be very into getting into this... I presume you can connect these to IR transmitters etc... have got an IR dimmer switch I was thinking of fitting in my lounge - was looking at getting something like redeye and then controlling TV, lights etc.. from my iphone but it might be more fun to try and play around with/build this stuff myself.

Thing is though when are you ever going to have 56 things running on it? even the largest midi controllers I've seen have been made using a teensy 2.0++.

Parallax are the chips slated to take the world by storm, but I'm still excited about the raspberrypi, if only from a micro htpc system. for $25 it's worth a punt.

I have both a nanode ( kind of stuck for ideas at the moment to use it, might play with making it a sensor service of some kind) and the teensy2.0 (not the ++, prefer the smaller factor of the 2.0) and I can't stop thinking of ideas for that

http://Http://www.pjrc.com in case you fancy checking out the various projects folks have done, or buying one.

At the moment I have a prototype spooks style dlp-bypass tool.

Its slow and flaky but I've successfully transferred "hello world" style ascii text, audio and image files using it, without the computer seeing it as removable storage.

We've proven the concept, just a case of getting it together enough to present at a conference or talk before anyone else beats us to it, just we're always stupid busy so have no time to push the development faster.
