Thanks for your patience...
Excellent, once I get off shift in a couple days I'll reflash my Teensy, the other files are already uploaded to the RPi.

Been away for a while have the 1st version plugging away as just a remote temp monitor for now, got a new Pi and Teensy this week.

I am considering using the Pi locally with a screen to access the Teensy controls. If I were to use the Occidentalis distro and loaded a Apache/MySQL/PHP what else would I need to access the Teensy? Would there be enough power to run the GUI and TeensyPi functions?

I've run the TeensyPi on the 256MB version of the RPi with no problems, so if you wanted to run a GUI, it would probably be OK, if you ran a lightweight browser on a 512MB RPi.

The RPi has about the same computing power as a Pentium III.

IT WORKS



This replaces the Adafruit Prototyping Pi Plate.

I've uploaded the Eagle Light and Gerber files to my https://github.com/jimmayhugh/TeensyPi for anyone that would like to make their own.

I used Seeed Studio's Fusion PCB Service, got 10 bare boards for about $35, including shipping.

This is also posted at my web site.
What are the dimensions of the board? Thickness you used?

You could just as well put the boards two-up on the 10cm x 10cm boards, and get twice as many boards for the same price--you'd just need to cut them apart yourself. Looks very interesting! I may need to take the plunge...

Do I hear a group buy opportunity developing? I'm interested in 2-4 boards.

Thanks...Jon

I'm not 100% happy with the layout yet, the next iteration will have wider power and ground traces. I may also consider springing for the hobbyist verson of Eagle in order to do 4-layer boards.

I'm also not a vendor at this site, and don't want to imply that I'm trying to sell anything, which is why I made the Eagle and Gerber files available.

Any thought of using that blank area for a bus to connect temp sensors and another for switches?

Also, did you ever figure out the LCD's? I got the Raspberry Pi LCD Plate from Adafruit (i2c and buttons) and cannot seem to get it to work. I'm not sure if it is because of a conflict with the Teensy... I am currently troubleshooting.
