Seems rather straight forward for someone who know what they're doing...
I was thinking a plugin to work with a Phidget interface module and a couple of Phidget temp sensors.
One to monitor cabin temps and the other to monitor outside temps. Maybe even a warning system as the temp falls towards and below freezing?
That would be COOL!
Then just add the rotary encoder input (http://www.phidgets.com/products.php?product_id=1052), and then servo control (maybe this one - http://www.phidgets.com/products.php?product_id=1000), and we could have a complete HVAC control in CF!
Edit... Sorry, looks like somebody has already been working on this... http://forums.fluxmedia.net/showthread.php?t=1643
That project, the car already has climate control...
My car does not however. But the possibility exists!
Just so you know all that is doable with the Fusion Brain as well for less money.
User "h3rk" is doing automatic climate control right now too.

Dammit, I love this ****!!!!
I don't know about FusionBrain...
I can't find servo motor control mentioned anywhere. Phidgets offers so many different add on boards, manuals, source code. Fusion doesn't seem to offer much at all.
Also their pricing seems a little dodgy... the comparison on their website shows the Fusion Brain controller sells for $50, the catalog says $65, and when you add it to the cart its shown as $70!
3 servos, and 3 of the driver circuits, and 3 usb ports. That would be a minimum for the phidgets servo setup. Then you have to find a way to rig those servos to control the doors. (keep in mind, 3 is a minimum for complete control of HVAC. Unless you have a vacuum setup, then maybe just 1. But there's a minimum of 3 doors.
I'd rather interface with the existing actuators, and minimize the hacking-up of the dash underside.
The comparison has not been updated.Originally Posted by pearl62
The price is $65 fot the Brain. If you want a 6' USB cable and a DC jack to power it, which is default option #1, then it is $5 more. There is a drop down menu to select if you want the cables or not. If you dont want them, it is $65.
The brain was $50, but due to various reasons it is now $65. It is still waaaaaay cheaper than anything else with half as much goodies on it.
We have an entire subforum here for support, as well as we answer emails as immediately as possible.
We have fully customizable and skinnable software available, with a newer logic based version due out very soon (Uber Edition).
We have all the details provided to interface directly with the low level DLL's if you want in both C# and VB.

Ok, I'll check it out here. There just wasn't any links to support docs on the FusionBrain site.
Another thought was just using the Parallax Propellor chip (http://parallax.com/ProductInfo/Micr...7/Default.aspx), which can support direct video output. I could drive and sense just about anything with that, and output a nice graphical display to one of the composite video inputs on my LCD. I could even integrate a 3-axis accelerometer too for a nice G- meter on the same screen, or even add OBD gauge display.
I have a 96 Civic which has a cable actuator for the temperature only, the rest of the controls can be done with output relays I think. There is a guy here who has fabbed up a servo to control the temp, so I know it's possible.
Anyway, just brainstorming some ideas. I can solder, and write embedded code, so I'm not scared of a more embedded solution. Integration with CentraFuse would be the best though...
So I'd need a servo to operate the temp dial and a servo for the vent selector...the fan speeds, rear defrost and A/C can be controlled as analogue outputs I'm assuming?
Then have it monitor interior temps, and have the PC control fan speed/temp to maintain the selected temp...
Am I missing anything else?
