I'm up for that. Let me know if you need any help.

Ah, no worries Meddler, things are going well here in Melbourne :)
Just used Robby's RoadRunner plugin to test the TPMS, and it seems to be working fine.
Come the weekend, I will fit the sensors to the wheels, and post some pics after.
Things are coming along very nicely indeed.
Robby will release a standalone windows-based tester for the setup, and another guy over at flux is completing the beta for the Centrafuse plugin, so within a week we will be in car heaven..
lets hope so :)
Ok, as promissed, a few detailed pictures of how to do the TPMS setup, based on RobbyBMW's PIC USB interface, and the 3rd Eye TPMS kit.Quote:

Another shot, showing the rear, with the serial number in this case, of the RF module.
I decided to get her naked, and expose her innermost secrets to the salivating masses out there....
And take off some of her clothes, actually, completely strip her - lol...
Well, I got lost for a moment there, soz about that....
Here is a pic showing how I desoldered the LCD board, and ending up with the RF/PSU combination board, and the LCD/Decoder board.
And here is a shot of the same from the back, the piece on the bottom, right, is what we are interested in - the RF Receiver, repsonding to frequencies at 433,92Mhz.
So, we need to do a bit of dremmelling, and end up with this - be very, very careful of firstly, statics, and secondly, to cut just to the left of the little divider line on the PCB - the larger portion must be the RF Receiver part!
And here is the connections to be made, they will be soldered to pins on the PIC USB interface pcb:
to give us an end result, looking something like this (hopefully yours do too):
I just thought I'd post a good guide on how-to do this mod, as it's not as simple as it seems by reading Robby's thread, and, if you're not familiar with electronics, and do not own a good, fine-tipped soldering iron, don't attempt this, as you would ruin a perfectly good TPMS unit.
What did we achieve by doing the above mod?
Well, now you can display your tyre-parameters directly onto our Carputer Frontend - the plugin for Roadrunner is ready, and working, and the Centrafuse 2.1 one is available too, thanks to Wolfgang.
Nice, and a good safety feature to add to your carputer setup.
Now you can start to understand why I opted for the very powerful Core 2 Duo based solution :)
Enjoy this thread, I hope it is helpful.
edit: One thing I did not add, and which is not visible in the photos - I added a piece of supporting foamrubber under the RF board, so it will sit firm on the USB-pcb, with no fear of vibrations causing any harm/loose connections.
Something to keep in mind.
excellent write up. Maybe it should be in it's own thread so it doesn't get lost.
yeah, nice write up.
I've just subscribed. My kind of build.
Searched the thread for info about your shutdown contoller as I've just built my own not knowing there was such a thing to buy.
What is it you are using and where did you get it?
Edit: Sorry. Found it. Carnetix! A USB controlled powersupply.
Just a quick feedback on the TPMS system - I had the pressure transducers fitted, and trained the RF Receiver to the sensors......and guess what?
It's alive - yeay.
Looking pretty good, sensor 1 = LF, 2=RF, 3=RR, 4=LR and 5=Spare. Temperatures, as well as pressures are spot-on, there's a little bug in the software incorrectly detecting sensor 3's battery status, as the original display shows that as full.
Well, we're making good progress here, another guy on Fluxmedia is developing the plugin for CentraFuse, and there is an existing plugin for RoadRunner. This is an excellent musthave for your car, and the way I have now made my unit is to display on the old, original LCD, as well as sending data to the carputer via the USB interface- for comparison.
Of course, both methods can be used simultaneously, and permanently, if so desired.
I am off to Finland till next Sunday (17th Feb), but will provide more feedback then on progress. I will be departing Friday afternoon.
Let me know what you guys think.
I will definitely add this to my system, but I have not had the time to fully investigate where to find the kit and who in the comunity that has the pcb adapter for sale. Or wherefrom to download sw.
Talking about Finland. Up north we have spiked wheels in the winter. Its by law acctually. I hope that I can get extra sensors for the extra set of wheels.
It would be nice to be spoon feed... :-) If you (someone) do(es) I'll put up the cash.
For now; great work mrB!
hey from what i saw up there, i don't think that i would work.. but are you able to get a bigger screen, like a 7" or 8" screen?
also how did you do the Stock screen in the tissue place... that looks really really good...
you ride looks alot like what i was plaing on doing... lol now i'll have to do some thing else...
