Why doesnt the sunroof have an AUTO switch similar to the driver side window? I think this would be a great mod !!! :rolleyes:

I totally agree. I often wonder why only one window has the auto-up feature. I wonder how much the sensor, etc upgrades cost. Heck - make it a "convenience" package with auto-everything. :)

I wish we can get all the windows like that...it would be so much easier!!!:dunno:

Life is a breeze when your windows and sunroof close without needing to hold your patience or your fingers. :)

Hey this is an interesting mod. This should be a very simple and affordable mod... I'm thinking under $40 for all the parts.

The design I saw at a-tl has one serious problem: once the sunroof is in motion, there's no way to stop it! Woe betide the guy who gets his finger in the way. He'll get his little pinkie crushed for sure. Also, there's no way to open the sunroof halfway. It's either fully closed or fully open.

The correct way to do this mod is to somewhat emulate the driver's side window behavior but with a modification: pushing any button during motion will stop the motion.

Do I hear "PIC microcontroller and cheap parts"? :D (BIG GRIN).

I really need to go out and get the Helms manual for the TL. The wiring diagrams are a must.

Hmm. Let's see, per-piece cost:
  • PIC microcontroller with 6 I/O pins ($5)
  • 3 High-current FETs to sink motor current ($6)
  • Voltage regulator ($5)
  • Handful of resistors ($2)
  • Printed circuit board and casing ($5)
  • Fuse, wires and miscellany ($5)
Total: $28

Development cost:
  • Serial port programming station ($250)
  • Pizza, beer and community recognition for developer (priceless)

darn it's out of my league again @[email protected] hey dave, go ahead, we are all awaiting :) but how are you going to solve the programming station problem though?

How many people want this mod? If there's enough demand for me to recoup my investment in the programming station and Helms manuals (and some money for my labor) I'll gladly do it for you guys.

I'm thinking that this mod can easily be extended to control other relay switches, such as full auto on all windows, and automatic opening of all windows and sunroof from the remote key fob, without having to invest in a whole new alarm system.

I'm thinking...
  • Tap on a window/sunroof switch = auto open/close.
  • Hold the button down = manual open/close. (Just like a CD player's FF and REW buttons -- tap = next track, hold = FF)
  • Push the Door Open button on key fob four times in five seconds = open all windows and sunroof.

The remote windows-down function depends (of course) on whether or not I can rig the windows to be on all the time, and not just when car is on.

The software can be quite complicated, with lots of conditions that must be handled, and safeties that must be taken care of. We also need to use Industrial grade parts for temperature tolerance. No problem! :D

I'm sure you wouldn't say it's out of your league if you look at how a PIC processor works. Those things are the easiest to program :D I've probably still got some of my old code from a class about 2 years ago ;)

wow

dayam...Why can't we have talented TLers in ATL? this sucks...Is there even a meet in ATL for TLs??? I've only seen one blue tl-s that modified....

Daverman: if you ever come to ATL...let me know...you can do my car...I'll give you $100? or u need more?

If he goes the embedded systems route, he's going to need to produce enough of them to recup the costs I'd imagine.

Daverman, if you need any help with the digital side (PIC, keep the FETs the hell away from me) I can probably help out. Let me know.

i am in, dave. i love those features, particularly i think the all windows / sunroof on with remote is awesome. let me know what you need and i will try my best to help. i don't know how many people we could gather but i think if we really call on it there should be quite a few participants, coz' i have heard a lot of compains on the sunroof.

OK, let me do a little research on the PIC chips. And I wouldn't mind taking a Helms manual off of someone's hands either :D

Yup.

Fortunately PIC chips aren't that expensive, and neither are the rest of the components. I just have to do research and put in labor.

Yes there is a "stop" feature

When I posted the design for the one-touch sunroof switch on the atl forum, I did include a way to stop the sunroof. It's real simple and doesn't require any type of fancy programmable logic, just off the shelf components. I made it so that the center vent switch also doubles as the "stop" switch.

The overall design is real easy. Think of your sunroof switch as three seperate switches (cause that's what it is). When you press a switch, it momentarily connects a wire to ground. You need a timer module that will hold the circuit closed for a set amount of time, and you trigger that timer using the stock sunroof switch. You hook up a relay so that the timer is disconnected/reset when the vent switch is pressed. The vent switch will still function as it normally does. The open and closes switches will open or close the sunroof fully. Pressing the vent switch during automatic operation will stop the sunroof motion and leave it in its current position.

By the way, the stock sunroof switch is connected to a relay which controls the sunroof motor and has some logic to figure out how to power the motor dependent on its current state (opened, closed, vented). So when you work with the switch, you're working with low current.

Again, for the windows I recommend buying a commercial window module like the DEI or clifford ones. If I hold down a window switch, it will go up/down for as long as I hold it. If I quickly tap a windows switch, it will automatically travel up/down the whole way. Works like a charm, but is not compatible with our sunroof.

I meant to recup the cost of the evaluation board.

Bebber's right, his design is fine. It's just not something that a lot of people would be able to rig themselves. Maybe if you post some Radio Shack part numbers and show them how to wire it up (mmm... on a protoboard? I wouldn't take the time to make a trace for something like this) then some people might do it.
