MotoDisplay

I am looking for input on a potential new product I'm working on - The MotoDisplay. I've posted this in the Vendors area even though I don't have a product for sale ( and frankly, may not ever have one) but I'm looking for potential user feedback.

So what is the MotoDisplay? Currently, I am finishing up a test product that has the following feature/specs:
  • Custom hardware using a Cortex M4 microprocessor
  • 2.7" OLED daylight visible display
  • Weatherproof enclosure
  • GPS based speed display
  • Dual 9999 mile trip meters
  • Altitude display
  • Date/time display
  • Lat/Lon display
  • Compass heading display
  • External temperature display
  • Voltmeter display
  • Accelerometer
  • Lean angle indicator
  • Recording of the above data to a log file
  • Log data retrievable by WiFi access to the MotoDisplay
  • User selectable display formats

I would love to hear any and all ideas on things you would like to see in this device. A price point where you would buy such a product would be great to know, too. Any feedback is greatly appreciated!

I hope to have a prototype product completed in the next 30 days. When I do, I'll post up some videos.

What is the overall physical size of the unit ?
If it is small enough to place efficiently and the price point is right they should sell.
LD riders would possibly incorporate it into their vast array of gadgets.

Any chance it will be adjustable tripmeters? Possible to add buttons so it could be operated from handlebar if so?


Looking at something right now to use for roadbook riding and the options out there are quite expensive and not that much to choose from.

Approximate size is 4.5"W x 3"H x 2"D. The trip meters are individually resettable. Remote buttons are technically feasible. Right now, all user interface is through one rotary knob and one push button.

I have some prototype circuit boards built and have all the hardware for the first prototype assembled. I'm working on the software side of things now. I do have the basic software done and I am now working on all the user interface stuff. I'll try to post some pictures tomorrow of what I have so far.

I'd be concerned about using GPS for speed and distance tracking. There can often be a large amount of variation that would significantly increase the recorded distance traveled, versus using wheel rotation. Those that may rely on mileage to identify turns, could big significantly off. The rest looks like a good start.

That certainly is a valid concern. I've designed the hardware so it has the ability to add additional functions and sensors, such as reading wheel rotation. Modern GPS units are very, very sensitive and accurate and often include the ability to provide Inertial Navigation information for short periods when the GPS signal is lost or inaccurate. The GPS module I'm using supports this, though I'm not currently using that feature.

The GPS unit I am using is accurate to within 2 meters and can update its position up to 5 times a second. Additionally, for this use we don't need absolutle accuracy (GPS position vs actual location on earth) to be super precise (2 meters is adequate), we just need relative position accuracy to be consistent (each position fix needs to have the same absolutle accuracy error), so we can accurately determine distance traveled. It should be as accurate as wheel rotation based distance calculation, but only testing will tell for sure.

I didn't initially include the ability to read wheel speed as it wasn't a concern for me in my initial design. I did not have any intention of creating a commercial product when I first started on this project. I have been thinking about a second product that would completely replace all gauges, warning lights, etc with a digital display, but that is a significantly larger undertaking.

Have not ridden anything following a road book yet but seems like a fun way to navigate and have been talking to people doing it and the most common way these days is to ride on the total distance and that required an adjustable trip meter, so when you arrive at a turn it must be possible to adjust the trip if its a little off.

So lets say the turn is at 17,20 km and when getting to it trip reads 17,25 it must be possible to step it back to the known 17,20 km.

And another question can it handle both miles and kilometers?

Sounds really interesting. I guess the question is what would you predict the pricing to be?

Anything is possible in that regard - it's just software. Miles/km is easy.

Not really sure at this point. Maybe around $200, depending on features.

Here are some photos of the first prototype unit. It not in a case yet as it's my software test unit.

What will the input requirements be ? Just power and ground ?

Will it be readable in the direct sunlight ?

Yes, just power and ground. It should be readable in direct sunlight, though I haven't actually tested it yet. OLED displays generally do well in direct sunlight.

Things are progressing along. Prototype hardware is finished, other than the hardware for the lean angle/acceleration sensor. I'm waiting on another vendor for the prototype board. All the basic software is done. I'm still working on the configuration menu system and a few other odds and ends. The enclosure is just a temporary setup and I'm looking for something more suitable for the final design. I may have to have something custom made.
