Bluetooth enabled programmable LCD display?
-
This summer I bought a small, cheap motor scooter (EU small motorcycle class) for local journeys, as a contribution towards slowing climate change. My 4x4 Vogon constructor ship* sits unmolested in the driveway most of the time now. The problem is that the scooter speedometer is both wildly inaccurate and inconsistence, and it has no trip meter, and the fuel gauge equally useless, and there is no clock. The fuel gauge shows full when the tank is full, but half full after using less than a third of a tank, and then empty when there is a good 40% left. No problem! Out with the Android 'phone, wake up the brain, and roll my own dashboard - GPS for speed and distance, and with fuel consumption calculated from distance and time to cover it, logging starts, stops, and acceleration after stops to determine the type of driving - urban traffic, normal urban or open road. On testing, it worked well, and the calculated fuel consumption was within 1% of actual consumption. The problem is - in Cyprus sunshine, no matter how I orientate the 'phone holder, it is impossible to read it from reflections and glare - and if I am wearing light coloured clothing it gets worse. Now, some time ago a cyclist was telling me that the latest bike computers consisted of an Android program using Bluetooth to update an LCD display on the handlebars - and LCD screens are easily visible, having tested it with a handlebar mounted clock and thermometer on the scooter. What I want is to get hold of these Bluetooth LCD display device, together with the appropriate API so I can drive it with the functionality I have already built. I have Googled, Bingled and DuckDuckGoed to my heart's content, but so far no joy. Can anybody source one of these things? I would really like to get a reliable dashboard before I start getting speeding tickets and/or running out of petrol miles from anywhere. It just needs four lines for speed, time, trip and fuel %. Pretty please! :) * Vogon constructor fleets were tasked with destroying planets - ostensibly that obstructed a new space highway, but I think they just did it for fun.
This also may be useful for local trips. As for a dashboard I guess it will have to strap to your hand or arm unless Google is still selling their glasses. https://shiftrobotics.io/[^]

There are "electronic RF shelf labels" that might fit the bill. This looks interesting:

"Before entering on an understanding, I have meditated for a long time, and have foreseen what might happen. It is not genius which reveals to me suddenly, secretly, what I have to say or to do in a circumstance unexpected by other people; it is reflection, it is meditation." - Napoleon I

Do you bring your towel on each trip?

If you can find a suitable LCD with eg I2C or SPI connection (on eg Amazon), it's pretty trival to turn it into a Bluetooth-connected display with an Arduino Nano BLE (or similar). Depends whether you're a bit of a DIYer.

You could look for e-ink devices running android. There are a few. E-ink is also perfectly visible in sunlight.
