Anything Raspberry Pi related coming up?

[Joshua D. Johnson]

I won't be able to make it tomorrow but had a few questions.
I picked up a Raspberry Pi at the Maker Faire., it was relatively easy to set up and run to include some basic functionality including Java and Arduino. I'm wondering if anyone is doing anything more with it? I've had trouble getting my Arduino drawbot running via rxtx and I'm playing with python a bit.. it'd be nice to have a non-newbie give a little class and demonstrate projects of their own.

Thanks!

I've been working on a couple of projects with the Pi. I've added a micro wifi dongle and I'm investigating how to embed it into an Ikea Fado table lamp. The lamp bulb will be replaced with RGB LEDs and color fading patterns will be used to represent data the Pi pull downs from the net (weather, traffic, stocks, email status, etc.). This is similar to an "ambient orb" but would be more flexible/hackable and controllable by a mobile phone or tablet. I've created a prototype at this point, but my LEDs aren't bright enough (BlinkM MaxM) so I'm looking for something more powerful. I want the lamp colors to be visible in full daylight and they currently are only visible in a somewhat darkened room.

I've also recently ported the ChibiOS/RT real-time operating system to the Pi. The port currently supports thread scheduling, GPIO ports, a serial data driver and I2C. I'm working on a driver for SPI and plan to do drivers for PWM and a general purpose timer. After that, if I'm ambitious I might try adding support for the USB host and LAN. My personal goal for this project was education about bare metal programming and real-time operating systems and it's definitely been very educational (and even fun, most of the time :-) )

Sounds complicated. I was able to load the SD card with Wheezy (from windows) and figured out a really simple way of enlarging the Linux/Windows partition on the card and have started uploading software. My goal is to first have a fully capable >$100 computer for my 6 year old daughter. After that'll probably get another one and try getting a touchscreen USB monitor to work along with wifi etc. Alot of that seems complicated but maybe because I have zero Linux experience. I did get arduino working but found it not so useful since HDMI screens tend to not be portable. 

Thanks for sharing!
