This is my homemade 5.25" bay LCD display to show temperature and flow rate. The display runs independently of the computer on an Atmel AVR MCU. The display is a Nokia cell phone 130x130 pixel color LCD that shows a graph of water temperature, the minimum/maximum range and the flow in liters per minute. I can post more build info if anyone is interested.

I'll post the schematics, code and eagle files on my site soon. This AVR has no USB hardware, although it is possible to implement USB on this chip in software.

Yup, thats what I mean, if you still have enough space in there, an usb stack will be really handy, especially with long term logging, also and additional IO port for AD for temperature probe if you still have spare there, that will be really cool.

Again, really great job & thanks for sharing ! :)
