maybe we could com up with an interface to control
the ac/heat via computer!!! then we could have auto climate
I was thinking of the idea of controlling the Heater/AC throught the computer. However, if your computer crashes and it's cold out...you're gonna freeze your a** off.
I had the exact problem with the screen and had to move the AC controls. They were moved onto the ceiling to make room for a 6.4" TS..which would be the same as a 8.4".
sorry dude, my bad.
i went back to the shop and it says you can hook up a lcd flat panel not a barebone lcd.
i read it on the fly, so it was only a quick glance.
You know, there were some 12" bare USB touch-screen LCDs with VGA input on eBay the other day for like $350. So I'm sorta thinking I'm gonna skip the Sharp display for now and hope that when I really want to blow $300 on a display for the car, I'll find a deal like that. Plus I have a composite-in LCD on the way that I'm gonna play with for a while first.
I have a bookmark of a site somewhere, a guy talkes briefly about removing the ac controles, and hooking them to the pc.
I have been looking into this for a while, I just dont have much free time to play with it right now. but here are some factors :
1. Old cars use a lot of manual controles ( push rods, and vents and stuff) new cars use switches and POTS to controle stuff. The new stuff would be a lot easier to manipulate. Push rods would require some sort of actuator or servo.
2. As previously mentioned, you dont want the pc crashing to mean the end of your AC,
3. After you move them, you still have to plug up the holes , or make a new dash, and depending on your set-up, you might need to pick a new home for the controles.
So far, my idea is : A Basic stamp.
They are tiny computers that have a serial or parallel interface to the pc, but they have there own ram and can operate indipendantly of the pc.
So, it would be pretty easy to hook up a Basic stamp to the ac / heater controles, throw in a temp sensor, and write the code for the stamp to control everything. and when you had the pc turned on, it could also relay the data to the pc, or allow the pc to adjust the tempature and stuff.
I have big plans for my stamp, I want it to control the door locks, the windows, interface with the alarm.... it just takes time.
i think i could handle it. I have a 2000 vehicle and i already
took the radio out and looked at the climate control unit.
Looks like only about 10 wires total and i am guessing they
are just switches. if i new what the switches did then i
think i could program it up no problem, I just don't know
how to interface the hardware. You would basically need
a temp sensor as input and then the several output switches.
if you can find that link please post. I'd like to look into this.
the problem is that i would have to have the system working
quickly because i don't want to go without AC system for long,
if i decide to rip out the controls and mount my lcd there.
