Absolutely.. admittedly I have a software bias and see design challenges through that lens. My choice here would probably be WebBluetooth in a PWA app. It is then 1 application for most platforms. But that said, I acknowledge the overhead and while I would not mind throwing down the code myself it would require maintenance and patching, 2 years from now x api is no longer supported and the reality is hobby time is hard to come by. Now if it were something that had a wide audience and was no longer a hobby, that is different :P. All joking aside though I think sort of scope creep is what i feared in general with the screen and touch. I am curious to see what the possibilities are too (and open to them) but unless it is something really killer, I think I am personally more inclined to go with the simple buttons that don't have me taking apart half my interior to run wire to the screen. Ironically I used to rip brand new cars apart and stuff them full of screens, computers, cameras and all sorts of **************** and now I want them as close to original as possible.. Sorry, digression

The radio would also require FCC ID (if compliance is an issue for anyone) :/
Yes.. when it comes to hardware i live blissfully in the naive prototype playground, buying controllers with approved radios, etc. That said I am following this thread with great interest because I want to understand the process better. Thank you for providing all the detail you do. When I get a few breathers over the next couple of weeks I am going to try to dig more into the details

I agree, but I think the other factor is how integrated it is and accessible. I think an android auto / apple car play head unit app that let you manage all interior led colors would likely get a lot of use. For all I know they are already available.

If there is anything that could convince me otherwise please do let me know and I'll reconsider my opinions. Thanks for trying to help out, appreciated btw!


Edit: Adding in a MCP2021A-330E/SN, sort of a gift to our Devs who wish to have both read & write access to the ECU and car data and/or build their own HMI around that (comm via k-line over 10400baud). So see, plenty of other tricks you'll be able to do with this lil cool box
Cool.. looks like a basic serial connection, could actually send that to a BT module if i got the inclination (or just solder up to a Arduino's serial for simplicity) and got board and wanted to create such an app . thank you!

BTW.. what type of messages would I want to send over the connection to the controller?? (Sorry if you have not gotten this far yet or if you posted it already)

Pardon my short memory I've just realized we had a chat about a car PC a few months back. Glad you've found out this thread and chiming in some good points, all very valid in fact (thanks!). If all of that stuff would be easy to implement trust me I'd swing in all your ideas in a flash, but as you know (I'm sure you do) its always about compromises :/

Didn't know Apple brought-in interior lighting control in their product. I find it rude that they've forgotten all about the SkyBreaker. I'm insulted, let me raise an official complaint right away

A BT-over-uart would work perfectly fine, good idea btw! That uart would take a 0x33 "init" at 5 baud (write), wait for a 0x55 response from the ECU (read) and after that you'd send out requests (mode, PID) to comm with the car. e.g.

uint8_t message[5] = {0x68, 0x6A, 0xF1, 0x01, 0x11}; // ask for throttle pos

Modes and PIDs conversion at https://en.wikipedia.org/wiki/OBD-II_PIDs

Something like that.

ps. I'm up to hacking the A/F so to get seasonal performance maps uploaded. I may get in touch with someone I know back in the UK who specialize in car performance mapping and see if he is interested in partnership. e.g. you'd buy his engineer service, get a re-map for your vehicle and have that uploaded before a track day (or illegal night race at the industrial park, in my case LOL) and have the original oem map restored after that, You get the idea....

Anyway. All-very-early indeed. pps; Just had two of those (kick-arse) capacitive displays arriving today, I'll breadboard one over this evening to confirm the pinout and see how that goes! They are incredibly beautiful and well engineered it appears, so slim too

How about lighting effects that change with the audio of the sound system?

There are systems out there already that work with LED's and Bluetooth. I have XK glow for ambient lights and you can do alot of cool colors and have it change with speed or music etc..

The capacitive touchscreen is cool if we could fit it in the batwing area? I have some buttons there for heat seat warmers and the LED light. If that was touchscreen it would set it apart.

Also look at this on eBay

True that, its all over here too and in several voltage, port to android, iphone, hand held, you get dizzy just looking at all those options. But none can do brake signal input, expand to dev's thinkies (k-line?), and none comes with a sexy CNC enclosure with a built-in quality IPS capacitive touch display

Thanks for linking-up, good catch I had that in mind too. We have them here in fact, 100% custom. Using a similar solution from a domestic manufacturer for an HMI active membrane switch (recessed push-buttons and clear window). Completely different alley though (i.e. automation system). You send them a *.AI template with the pantone colors and they ship you out your membrane in <48hrs. Interestingly enough, they cost X5 more (per unit) than that IPS display if you consider a small quantity... which is our case :/

Anyway. All brilliant ideas none the less, thanks for sharing those along guys and keep em coming.

Sounds good, theyre pretty easy to come by on the used market so I ordered one off fleabay for $100 (hopefully its in good shape). Shoot me a PM (or reply to the PM I sent you a couple weeks ago) with your mailing address and Ill send you 2 kits, send me back the best of the two and the other you can keep.

They'll both be refitted! probably going to get that extra one priced eventually so pass on your paypal addy and I'll void the shipping cost on those. Pm sent.

They are so nice, do the middle wind reflectors make ahuge difference in noise? I dont actually have one.
