Help with water level problems
by Eric Martin
Hey all,
I had a close call with my hot water heater this afternoon. I heard on odd
noise in the pipes and it turned out that my hot water heater was dumping
water out of the overflow valve. Luckily, I found it quick enough, and I'm
pretty sure I got it handled for < $150. There's a 1 Gal bucket under the
overflow valve, and if I had a water level detector emailing me that water
is in the bucket, I could have caught this earlier.
I was looking at buying an Arduino and setting up a simple circuit. I know
a few people have played with Arduinos, any suggestions on which one to get
and how to go about it? I don't need to know how much water is in the
bucket, I was thinking about a float type device or even two wires that
trip a relay. I just want a heads up that water is in the bucket so I can
stop before my basement floods.
Thanks in advance,

A question about KMS API's
by Jason Couture
Anyone know anything about the KMS API? From userland? I'm working on
a project and would like to use KMS/FB directly, as at boot there will
be no binaries available except ours, No libc even. Just a few static
binaries. if anyone could point me in the right direction, it would be
greatly appreciated it. I can't seem to find anything on it on google,
and I really don't have the time to go pouring over the kernel source.

Re: [Wlug] Wlug Digest, Vol 106, Issue 5
by Karl Lind
Hi Chuck,
It doesn't have to be 2 HDMI compatible outputs. It just came to me that
the Pi has a composite video and a stereo audio out port too. One of each
would be super as I have power supplies, keyboards and mice for both my
Pi's. The four OS's (which might be overkill for time) that I plan to bring
for the demo are Raspian (a Debian distro that is running a web server),
Gentoo, Fedora and OpenELEC (an XBMC type distro). Also if possible
Ethernet access?

September talk
by Karl Lind
Yep, still up for it. Is there a way to connect two HDMI sources up to
projector/tv/video in the room? Reason I have two Pi's and I thought after
the talk can have two running for demo purposes.

Hi Karl,
are you still up for giving a talk on the Pi for the September meeting?
So
far as I know it's open for topics, and that sounds like a great one.

September meeting topic?
by Karl Lind
Howdy all,
I would like to give a talk on the Raspberry Pi project and I have two
of them to demonstrate various OS's (I have worked with the Debian and
Fedora implementations and look forward to the others as they come
out.). I have four SD cards, so that's the number of OS's I can bring
with me.
Have a great summer!

BBQ tues aug14 6pm Boylston,MA (addr,directions...)
by Doug Mildram
Sorry if the last-minute planning was inadequate for anyone.
Few replies so far == small turnout == could be good anyways!
You and even friends/family are invited to my house, roughly aug14 6pm-8pm,
540 Linden St Boylston MA (red house on corner of Mile Hill Rd,
probably enough room in my driveway for all to park, then street
is OK)
I've got ample burgers,sausages,cheese,peppers,onions,buns,tortilla
chips,salsa;
less beverages.
If you like old-fashioned verbose directions, choose one of:

Cross-compiling for Windows
by dulsi＠identicalsoftware.com
I cross compile a program for windows on my linux box. After doing so I
grab all the dlls and package them up. Typically this involves grabbing
what I knew was needed and then testing on a windows box to determine if
anything is missing. Is their some program in wine that can output what
dlls are needed (like ldd) so I can write a script to package up
everything? Obviously it doesn't generally change except when I upgrade to
a new Fedora version but it would be nice to automate packaging
everything.
