Should Adafruit build an open source Raspberry Pi?
Today is “open source Nest” day it seems! We are considering doing an open source Nest based on the Raspberry Pi if there’s enough interest – designed by Adafruit & Mike Doell. Here are the renderings Mike is working on.

I would love to see an OSS Nest competitor. Especially if the schematics are made available and information on how powering the thermostat was accomplished.
Definitely- I've love to replace our current thermostat with something better, and I'm a little wary of using Nest/Google since I'm the only one in the household heavily invested in them.
Absolutely. I just, two weeks ago, decided a smart thermostat was what I wanted to build with my pi. Having a resource like Adafruit (who know much more than I about how to do this stuff) would be great. 
count me in!  i'm about to move next month and was thinking of buying a nest. i think i might put that off for a bit :)
Hey, if you're looking for ideas - here are some of my dream thermostat wants:

1) Remote thermometers - I'd like to place thermometers in various rooms and have a "heat map" show me where my heat is going when the furnace is running.

2) Self contained web server - its cool to feed cloud systems, but I want full control. I want to choose if, when and what data gets leaked out about my system usage. Server should have full programming interface and usage history reports.

3) Zone controls - in my forced air house, this would be fairly simple - just some strong servos operating dampers receiving wireless signals. This would work great with #1 to allow me to warm up certain rooms and not others. Of course, the programming interface now needs to allow each room to have a fully manageable schedule :-)

4) Remote pressure (vacuum) sensor for monitoring furnace filter life. I've started doing this with my furnace - I don't have reliable data yet, but the sensor is able to detect the difference between clean / dirty, fan idle and fan full.
+Alex Wiebe just fyi re: "Zone Controls" - most furnace burners/heat exchangers are really only reliable when all of the dampers are open - it can actually create problems to close off too many dampers.  However, keeping the fan running when there are discrepancies in zone temperature is very efficient.
When I saw the headline "Should Adafruit build an open source Raspberry Pi?", my first reaction was "yes please!"
+Alex Wiebe Filter life is probably easier to monitor by watching the amp draw of the blower motor, or maybe in addition to pressure differential.
I would be in for one of these!  In fact I am so intrigued I will hold off on my purchase of a Nest for now, if this is something you are really planning to do.
A local copy of emoncms would be a good idea, and maybe partner up with the open energy monitor people.
Thermostats seem to be of big interest. I use wood pellets and a wood stove to heat a 2700' house. I used DS18B20s to determine the temps remotely. Using different sets depending on the time of day.  I would turn the pellet stove on and off with a small Python system and some X-10s., as well as the fan on the wood stove. I would have liked to use a linear stepper motor to control the vents on the wood stove, which would have given me more control over the amount of heat produced. I was usually able able to control temps in the master bedroom to +/- half degree, except when it was really cold (-15F). This system not only saved about 1/3 the fuel. but made heating by woodstove very comfortable.

But playing with fire is dangerous. Fail safes need to be built in particularly with wood stoves. Anything that left the vents wide open could easily produce a chimney fire, which in turn would burn down my remote contemporary log cabin. The accumulation of gasses is always a possibility, so their concentrations should be tested for too.

Next year the local gas company will be putting in natural gas, but even then you really want some fail safes to deal with equipment failure. Insurance companies are not fond of paying out for the errors of amateur (that includes me) electronics projects.
How about a furnace simulator too. Am wary of developing / debugging apps with real furnaces. I depend on them to keep warm and don't have any spares to experiment with :)
I was really excited thinking this was a Open Source Adafruit variant of the Raspberry Pi, but I'm also 100% behind a networked, webserver controlled extensible thermostat.
Is that amount of power really needed for such a simple device?
+Marek Dąbrowski Maybe not that much, but being able to be controls and configured by a web server and have more complex controls for heat management? Absolutely. A Pi based thermostat could be vastly more efficient than a standard programmable one, and given the low cost of the Pi, it'd be very cheap overall too.
Yes! Love it! I would totally take on this project!
What would be different to the current raspberry pi?

If there will be other models of the device, what is the whole point of the pi then? The pi is great because the hardware is exactly the same on every pi. So no unsolvable problems (because everone has the same setup and thus the same problems).

It'll make things confusing for the children, wich this platform is made for...
It would be totally awesome. I would like to see the ability to have remote temp sensors to place around the house for averaging. Automated motors could be used on ductwork to adjust the airflow and balance the home more efficiently.
A modular system that can be expanded upon, as needed.
Oh yeah, airflow sensors.
Thanks! :)
Better question would be, why not?

Looking at this post on G+ for Android it said "Should Adafruit build and opensourse Rasberry Pi", Yes it would be nice.
A well designed OpenHardware platform will be good.
Please consider aspects such as four mounting holes in an even patern for M3 screws, All the plugable IO (HDMI, USB, Ethernet, Audio IN and Out) on the one side so the device can be functionally panel mounted, a real power connector 2.1 x 5.5mm DC jack.
The AllWinner A20 is an interesting SOC with at least 1 Gig of RAM.
I don't even need one, but yes please!!! 
Here's my honest want: newer arm core supported by stock Debian, connectors all on one side instead of all sides, DC jack, 1 model, rtc, 1 sata port if possible. The obvious of being kmtruly open with no blobs. Target price: $60 with shipping? If you make v2, wait at least 18 months 
Let's do it. Open all the things! 
Yes, but only if there will be a fully supported kernel and preferably mainlined.

And it should be multicore, 1ghz+, 1gb RAM minimum, DC barrel jack for power and a power switch! 
+Mano Biletsky not using a deprecated core by Debian would be a big help. IMHO, the pi is on community life support while it's still relevant. Debian takes forever to adopt the latest and greatest (with good reason) but also I don't recall in my Linux usage history Debian deprecating an arch 
Since I recently got the pi and learning firsthand about its quirks, please add either an onboard reset button or at least include a reset pin header (pins preinstalled out of the box). Wake on LAN since the pi lacks that and can't be powered back up remotely after it's "powered off"
+Allan Jang that's because the Raspberry Pi has no power management. Powering it off isn't actually powering it off, you are just shutting down the OS... Picture an old pre Windows 2000 computer that used to shutdown tye OS then tell you turn the PC off.
Almost a year late to the party... does anyone know if this took off?
