2piR at Maker Faire
I'm sitting on top of the sensor board for 2piR at the Maker Faire in San Mateo. I just finished putting the final touches on the Debian machine that controls everything. We're in the process of hooking up the ignition system and the sensors to the controller board. Soon we'll do a leak test and then we'll burn some fuel off!

If you're in the San Francisco bay area this weekend, I highly suggest you come down to the Maker Faire on Saturday evening (find us in the fire area of the map) to play with our interactive fire project!

A huge thank you to Team Friday for doing the transport and setup! I can't wait to get down there tomorrow and run the damn thing! :)

I didn't know you were part of that project. Rock, now I absolutely can't wait to see it. :D

While too late for tomorrow; I would still definitely recommend doing something different with the filesystem. Ida know what crazy JFFS l00n1x crap is all about; but you can just as easily mount -fr or set ro in your fstab. There's also tmpfs and using memory and all; but I find that if it's just running one piece of code for a limited period of time; I don't really care about lots of spurious errors and whatnot, because who cares if the system can't write to syslog or whatever, it's not like you'd ever be trying to look at the logs anyway. Sometimes a single-task system is more useful than a bloat of an OS underneath it; but just because we don't always have that luxury, doesn't mean we necessarily need to care about the other things the OS has running that aren't relevant.

I know flash has improved, but it's still a really bad idea to leave it mounted read write on an otherwise 'embedded' device. Heck, I didn't even leave my 64MB shellbox readwrite 90% of the time and I used that as a primary shell for a couple years (I'd only mount it readable when I needed to add a program or change something).
