Has anyone here had any experience with the Arduino platform? (www.arduino.cc)
I've occasionally played around with them and after suggesting someone should do an Arduino talk at a Linux users group I want to to explain how I tried interfacing an ethernet development board to the Arduino. It appears I may have volunteered myself to do a presentation at some point in the future (oh dear 
)
If any of you have used it before do you want to share your experiences and the kinds of things you've made these remarkable little devices do? (and where are the best sources of information)
A little project I'm considering is networked power meters along the lines of a similar project at www.ladyada.net.
The key difference with what I'm looking to do is to have the meters send their usage information to an Arduino which will be connected to an ethernet port. Reason being I'm planning on hosting the server side on an ESXi virtual machine which does not support USB (the ladyada project uses Digi xbee devices which will connect to USB on the PC end) hence the need for a network enabled solution. I figure it won't be too difficult to use sockets to cobble something together in java that will colect the values and log them to a database. Then have a webapp that makes some pretty graphs (perhaps an android app too, dynamic DNS and a DMZ may actually prove useful)

I've got an Arduino (the ATMEGA 328 version) along with various sensors and a 16x2 LCD - my final plan is to get a digital MAP sensor and build my own digital boost gauge for the car 
If there was something simple/cheap I'd also try and interface into the ODB-II port on the car, and monitor RPM, engine coolant temp on there as well | |||

Nice, if I remember correctly that's the mini version? Try again. Fail again. Fail better. - Samuel Beckett | |||

Erm, it's the Duemilanove - it's not the smallest, but not the largest either (as far as I know) | |||

whoops, my bad. Checked the specs on arduino.cc and it seems to have the option of the 168 or 328 Double the flash capacity of the older chip - very nice. I've used the ethershield library in the past and was a little worried at how much of the precious storage space was taken up. If I run to storage issues then that could be just what I need. Try again. Fail again. Fail better. - Samuel Beckett | |||

Yeah - I _think_ the chips are interchangeable, so you should just be able to stick a 328 in there and flash it with the Arduino bootloader etc. |
