I recently decided I would like some gauges but didn't want to plumb them into the cockpit. I do a bit of embedded linux device programming and decided I could easily make a low-cost solution that is faster, energy efficient, feature rich, and highly customizable to your car.

I wanted to put some feelers out and see if folks are interested, and what features they might want. Depending on the size of the display, the complete kit would likely be in the $250 to $600 range depending on the display device & obd2 interface, and would be completely plug & play. These kits work with any OBD2 system, and are based on an android phone or tablet.

Tell me your likes, dislikes, missing features, etc. I need to know what would be important to you in ranking order, as some features may exclude others. Here are some feature options, feedback is needed before I mock up a prototype:

- OBD2 Data Customizable Gauges: RPM, Temp, MAF, Boost, Accel, Throttle, Coolant, etc
- OBD2 Diagnostic Code Reader / Fault Code Clear
- OBD2 Track Data Logger
- GPS Mode / Compass / Routing / Voice Navigation
- Rooted / SIM Unlocked / International Use
- Touchscreen Interface
- Customizable boot screen (spinning lotus logo? your car? your neighbor's wife?) / backgrounds / color theme
- Fast load time (~30 seconds)
- Dashcam Video/Mic Recorder
- Slide-out mini keyboard
- ECU map loading

The following require a pay-as-you-go data subscription from any cell provider (usually $40/m)
- Redlight/Speeder Camera / Speedtrap / Police Spotted Notification
- Local Police Radio Scanner
- Antitheft remote phone-home video / mic tap
- GPS Remote Vehicle Location Tracker
- Wifi / Internet Hotspot
- Cellphone / Speakerphone / SMS Messaging
- Email / Web Surfing
- Preshared contact messaging between the lotus community
- Remote vehicle disable

40 a month is a bit high considering 100 a year is all you have to pay to keep up to date with the 9500 series.

It is a great idea though packaging it all together.

Sounds like a great concept. I'm interested to see where this goes.

The option to choose the startup logo would be great so i could swap between the green and yellow lotus emblem and a spinning pic of my car or if it morphed from the logo into my car or my car into the logo would be cool as both are british racing green and yellow.

How is this different then using Torque on an Android device?

Absolutely interested, but also not sure how this differs from and OBD2 reader with eg. Torque app. Are you thinking of a double din display like the the Tesla din, or are you thinking of replacing the speedo / dash unit?

Torque would be a good target application, but one among many to likely the be customized and integrated. I'll give you an example. I just got done creating a large batch of high security phones, and while the individual apps could be downloaded to a normal phone, mine were configured and customized to work flawlessly across the hardware, communicate with each other on pre-shared credentials, with seamless integration in the OS. It changed it from being an app on a phone to an OS-integrated platform feature. For you it may be no different, and if you like running it as a standalone app, that's cool.

The alternative is I could convert your current android phone into such a device and give you the ability to flip between it's existing OS to mine. Another alternative is it could straight up be your phone and you could swap your existing phone for this device and put it on your service you already paid for.

Agreed. But you can't wifi hotspot, internet surf, email, sms, remotely track your vehicle, remote video/mic, or use a live police radio scanner or receive calls on your 9500.

The whole issue is the cellular data uplink being the source of the monthly cost. If you have a different way to get data, OR your existing smartphone can tether, the device can use those for your data uplink instead to avoid the monthly. The $40 plan i mentioned is just an unlimited talk/text/web plan from a t-mobile MVNO. Also, the monthly isn't required if you don't want those features.

One thing I didn't mention is that it could interface to your escort and provide additional premium services from escort, they have an android app for that ;)

but how much weight will it add :D
Approximately one instagram. :cool:

It takes those components to "stage 4" upgrade. I'm imagining a small tablet or phone device on a user-placeable mount. Depending on what ends up shaking out in the wishlist, you could be able to pick your display size from a couple or more choices so it integrates into your existing cockpit setup.

Where will this system be located? Maybe you could replace the single-din radio and have a screen that is slightly larger in its place, above the ac control and below the air vents.

Is this just a laptop that you sit in the passenger foot well? Or just an app for ipad/iphone/android devices? We don't have a large dash and something like a 4.3" screen will fit to the right of the ac controls.

I have a DashDAQ wedged beside the ac controls. It works well as odb2 logging and fully customized display (e.g. the bootup splash screen is the lotus logo). I haven't plugged in the wideband 02 yet but its wired and ready for whenever I get a bung on the cat.

Sounds interesting.

Not sure exactly what you have in mind but hope that the components that are used could be changed / upgraded at a later stage. E.g. I've finally got a 2din Tesla stereo surround, and I was thinking to put in an android tablet like Nexus 7 or something similar. However, the brightness of these screens are still not impressive, and I will probably buy another 7" tablet in the future once the screen brightness improves.

Also, as for the OBD2 connection, I hope you can make it turn off with the car, so it does not drain any power after one leave the car.

It would be a compact device that you mount anywhere in the cockpit you like using a standard phone or tablet mount. That means window, dash, airvent or shifter areas are all options.

SteveTx, do you have the $50-100k required to create this device, and its software?
I just finished a batch of baseband reprogrammed, on-the-fly nvram rewriting, custom designed ROM, processor modified, kernel hacked, rooted, sim unlocked android phones with cryptographically secure text, web, & voice, with remote lockdown and credential auth revocation and antiforensics. Way more complicated than this project, and it took me and a buddy 3 months from start to finish.

Can always use a Rasberry Pi/mini itx board in an auto enclosure and load centrafuse/meego on it, hook that up to a usb obdii, and get yourself a small lilliput screen.

I use to build custom "car-puters" for people, can do some pretty small form factor boxes now that will not add much extra weight...it did help that I do composite work so I can make double din enclosures for people that didn't have room for a 7" double din screen =X

mp3car.com has a lot of different apps and such.

Your auto gizmo would be interesting. Any products out there that just falls short or gave you the idea? It sounds like a pile of separate hardware that is available.

While you are at it. Can you please fix iRacing so it can run video cards in SLI or Crossfire?:)
That has stumped a whole community of sim racers and I want triples screens to run clean at 7680x1440.

See I read that wrong and thought you were asking for the 40/mo for access through the app. Makes a lot more sense now lol.

I can do it all with a tablet and obd2 adapter and cable. Subsequent interfaces could potentially be added for non-obd2 sensor.

This is caused by a race condition from dualing SLI instruction pipelines in the gpu, a failure of MIMO technology. Just kidding, no idea, never debugged it, good luck cuz I still need to do a deconstruction of the memory dump when my BF3 crashes.

RaspberryPi has a variety of problems and is an unperfected hardware platform. I would consider gumstix, but phones/tablets have already integrated the compenents in a tighter tiny lightweight formfactor than you could do gps, touch screen, processor, memory, usb interface. In a word, smartphones/tablets are ideal. And they have their own battery incase of intermittent power loss, can't beat that.
