I made a lean-angle sensor

Hi all,

I made a device that calculates your tilt angle when you ride. I did this as a hobby and out of curiosity on how much I lean in turns. Here is a demo of the device

I made one for myself, and 5 extra ones to give out. Please let me know if you want one or know anyone who does. All the parts (if you buy from China) cost about $20. I'll sell these at-cost (no profit), so $20 if you want one. I live in Bellevue WA.

Here is a paper I wrote about the mathematics, if you want to build your own. The mathematics are a bit tricky but this paper should explain how to do it.

I used the MPU6050, Arduino Nano with ATmega 328, and a 16x2 LCD. Both sensor and LCD communicate via IIC. If you want to build one yoruself you'll also need a battery connector and click button. I can give you the STL file for the case if you want to 3D print it, and the source code, just ask.

I just hope to get rid of these 5 extras, so please spread the word. Thanks guys.

Data collection. Synch to gps. Show angle and g-load on a map. Maybe color coded. Android app. Sell product for $100.00 on eBay. Sell app for 99 cents. Buy a new Panigale. Fucking brav-O, sir.

  all of them
Quite ingenious. Applause!

Like any truly original or inspired idea, it makes one wonder why it has not been thought of or available before. A displayed angle of lean feature could easily be offered as standard equipment on a modern bike.

One issue I see is the information is correct only when the bike is being ridden on a perfectly flat unbanked road surface with 0 degrees camber. Although it could be argued that the displayed lean angle would always be correct as compared to the axis of the earth.

Be careful moving forward or you may end up making other people wealthy with this and other ideas/inventions/innovations you have.

take this down, remove all the info and patent this...

I like this a lot, I can see where a MC company could incorporate this on a display screen and use it as a selling tool.

You could use a "sticky back" to secure the zip tie as well or even better a small magnet, check out Mag Daddy, we sell their product line and they're not only awesome the automotive industry has been using them for years.

sticky backs (they're about 5 cents....)

these magnets are insane, they hold like nothing you've seen before (no I don't get paid to advertise for them )

i almost want to come get one, but this - not for a second would I put it where you have it. what we need is someone watching a display on their bike? especially in the turns? to my mind this is good for post-attack analysis and not real-time observation. also, people are going to use this as a measure of performance. "Bro, I got my gixxer over to 47 degrees on that curve!" And it demands a graphical display rather than numbers. Still, this is great penis-measuring stuff.
