That's cool, Rodney. I'll back that. I already have the Arduino NXT shield, but haven't actually used it because I couldn't think of a worthy project. I don't imagine that'll be a problem once I have the greater power of the Pi.

Fwd: [AHRC - botlanta] NXT users - BrickPi Kickstarter....

rradf...@mindspring.com (R Radford) — Tue, 14 May 2013 13:50:09 UT

Saw this on another list and thought that all three lists (robotics,
arduino and NC Lego groups may find interesting - an addon board for the
Raspberry Pi that turns it into a robotic controller for the Nxt and
Mindstorm motors/sensors.

This is a kickstarter I am definitely interested in sponsoring... let me

Justice,

I welcome the offer to setup with the sparkcon folks.
Do you need min floor space requirements? I can run it off of a 12v
battery, no outlets needed.

Let me know, I owe a lot to SPARKcon and would love to help out.

R,
Alan

Alan,

SPARKcon and geekSPARK will have a presence at MakerFaire. Since your
Champ/Chump machine was at last year's geekSPARK, it would make a lot of
sense to co-locate with us. That way, we can all help greet folks at the
booth and we can all take turns seeing the rest of MakerFaire.

Kind regards,

Maker Fare in June

I was thinking of asking for some space for the Champ/Chump bike race
machine.
(If interested I can email photos of the machine, to anyone that asks, did
not want to post them to the group.)
But, I would like to walk around for an hour to check out what others are
doing.
my request:
Would any one like in the group like to hang out and talk about the club or

Re: [trianglearduino:1043] peculiar Linux/Arduino problem with /dev/ttyACM0

Hmmm? That is different than the experiences that I had. Reboots did resolve my issues. Please let us know when you find out the issue.

The change of behavior wrt tail -f reproduces across dozens of opens/closes as the device in question and it's ttyACM? brothers and sisters are created/destroyed as various devices are connected and disconnected, etc. The symptom is still there after a system reboot.

My id is still in the dialout group.

This is good information Bill, I have had the same situation occur on occasion and never figured out why, now I have more to check.
Thanks,

Bill's comment about something else holding the file open clicked and I
found this - avrdude may have left the file open.

It suggests using "lsof | grep ttyACM" to see if avrdude has it open, and
if so, killing it.

Are you in the "dialout" group ? run "groups" to find out.

I wonder if something else is holding the /dev/ttyACM0 device file open ?
lsof /dev/ttyACM0

I should have mentioned that programming the Arduino via the USB works
normally.

Pete,
It's probably something going wrong with linux usb enumeration or
permissions. Please post the (relevant) output from the following
commands after plugging in the arduino usb.

ls -l /dev/ttyACM*
uname -a
dmesg
