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

Let's see...I think we all agreed, that we would like to have that controller integrated into a Porsche rear view mirror, so we could additionally connect that to our WLAN backup cameras, right?

[Nine8Six]

Back-up cam?? you meant X-RAY Vision to see through clothes, right?

Man, the rear-view mirror enclosure. I think you are sounding innovation right there Bran! Let me have a look at the existing one and see if we could re-use the glass and mount but have it re-designed.

Any (other)brilliant idea(s) like this one, hit it guys!

If we are going to have a controller for the wind screen lights, would it be possible to add outputs or controls for the same or similar led’s to add footwell lighting or???

Quick Update on the LED winner; we are going for addressable LED. Most commonly known as WS2812B. Therefore a POS(+) NEG(-) and a IO (3-wires). The LEDs are independently/digitally driven by SPI and a clock source so this makes it much easier for me to drive this controller-side wise. It makes no difference to the user other than being able to create custom fading/mixing patterns and other cool effects, which I suspect will be of any interest or use, but the feature is there if needed.

Trying to visualize your idea. How do you see this working out installation-wise? Do we need a whole lot of lighting or 1 (or 2) LED is sufficient per each sides? I'm interested to hear more when you have time.

Is below what you had in mind? Something you can control via that SkyBreaker controller for both color and brightness? (Thanks btw!)


edit: don't feel overwhelmed by those ports, possibly going to be a single-core harness with a stress-relief boot instead (cleaner) or a one multi-pin connector sharing same GND and (+). Yet to arrive at that part of the design, just putting this here for feature visualization/debate.

Yep, love it! Depending where the controller is mounted I would imagine a strip or 1-3 leds depending on brightness to add under dash on each side for the footwell lighting. Maybe other light applications for those not interested in footwell lighting? Option for rope or others if the connections would be interchangeable and can be sourced even later?? Would the color/controls be independent of the skybreaker or need to be the same?

Question... If looking for more HMI interactions and possible growth, couldn't the controller wireless connect to either my phone or my headunit?

I have not done a lot of work with leds and their control, but in the robotics and IoT applications I have been working with it almost always makes more sense to manage the controller over wireless rather then add the complexity of lcds and touchscreens to the device.

Thoughts?

Edit: added:

I might be failing to correctly imagine the final outcome.. I am picturing having to incorporate a 2.4" screen somewhere in my car and although the mirror is a good idea, personally I think I would rather keep things simple in the boxster. This car is more about driving to me.. but if could control from my phone or headunit.. that is a bonus.

Read all, quoted the key message and understand fully what you are saying. And you are 100% correct. Main challenge being that cross-platform impediment and management from a coding perspective; Steve got an iPhone, Ruth got an Android, lil sister got an HTC, big sister got the new XYZ and cousin have his Blackberry, you see where I'm going with this...

Sought of using a cross-platform one-fit-all solution e.g. a browser addy http://xxx.xxx.xxx.xx:XXXX and port over lets say a NRF24L01+ or a LT8920 radio IC (2.4Ghz) but then the work involved is equivalent if not more than simply coding an X&Y axis touch screen. The radio would also require FCC ID (if compliance is an issue for anyone) :/

Finally, if the device would be used daily like a tune-in radio or similar then it would make sense to put in connectivity but in this case chances the color & brightness settings will be set once (or twice) then forgotten.

Not all lost cause. We'll have extra GPIOs on the device and probably use a nice quad size for developers to expand this controller to what-ever-they-want. That would include connectivity if what they add in the future requires that feature!!!

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

[Nine8Six]

Already half-way in the preliminary design. Sort of gauging what we'll need in term of hardware so to get this on order for tests. So far got the MCU, Display, a Quad-SPI Flash (for the display assets) and a K-line transceiver. Yet arrived to the SMPS, protection and filtering to power up that kit. We have a 64 pins quad there and from the look of things we'll need to beef this up to 100pins already lol All good fun!

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

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.

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)

[Nine8Six]

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

[rflores2323]

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.

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

Did I hear amber lighting .. good for speed yellow?

I'm in ..

I havent posted in a long time and lost touch. Nine8Six hasnt been active in years, is he still doing wind deflectors elsewhere?

[particlewave]

Nope. Went quiet, just like this forum.
