I'm not ragging on the concept or the engineering behind it, just how useful the output really is in the real world to a normal everyday rider. Fun to know, sure, but useful in a change my riding way, no. Kudos to motoru for the project, very cool concept and ideas for the future. Sent via SM-N900T |

Got mine today. It is of no use to Joe Ave. To someone who is working on there lap times it is of great use.

I briefly perused your paper - looks like you're using DCM for attitude estimation? Did you consider using a 9-axis sensor? Adding a magnetometer would increase the accuracy and stability, though depending on the placement on a motorcycle, the engine may cause wild readings. I spent a lot of time with this kind of thing on quadcopters (drones), gyros/accels/magnetos are a lot of fun to play with. The hardest part is always getting clean data, which I'm sure is nearly as difficult on a motorcycle as it is on a quadcopter (excessive vibrations). I highly suggest tying this into iOS/Android apps - I would definitely build one if you had it available but I have no desire to install a 16x2 LCD on my bike anywhere. Nice project! Seems like we have similar interests - sending you a message to chat about ideas ![]() |

Turns out I was taking the turns at 26 degrees, which means I can go faster. If you really think about it the only thing you really need is a speedometer (for cops), the rest you can go by "feel". It's just another thing to know. |

You can lowside with hardly any lean angle. It's about traction (or lack thereof) not lean angle. Also, if you are pushing hard enough on the street to need that kind of lean angle it's only a matter of time before you meet something mid-career that will upset the bike or rider enough to lead to a low or high side.

for me it would be great to have on the track. instead of asking the instructor about how far I'm leaning I can just check out the max lean at the end of the run. another good use I see for it is hooking up a warning light to go off when it gets to a certain angle - say 1" from scraping your pegs/exhaust as a heads up that the bottom is about to hit. I think HD riders could definitely use something like that. good stuff! EDIT: how about getting a max wheelie angle? would placing the unit rotated 90* from normal work for that? ![]() Edited by Nathan on Jul 19th 2016 at 08:26 AM |

Hi mate I'm requesting to purchase one of these lean angle sensors you have made ,I know it was a couple of years ago but hoping you can help thanks Greg.

I'm curious as to how the device compensates for the g-forces present during a turn. Gyroscopic sensors are generally used because they ignore these forces. A pendulum-style sensor will settle somewhere between gravity's pull and the lateral g-force generated while in a turn. It can only read accurately while the vehicle is standing still or moving at a steady rate in a straight line.

Let me know if you make any more in the future. I'll be happy to buy one from you. Greg |

there's an app for that https://www.racetimeapp.com/en/technical-features/ interesting that when they talk about recording lateral G-forces they specify that it is especially for those on 4 wheels... Edited by Nathan on Nov 8th 2018 at 07:29 AM |

I picked up a big V-twin cruiser and just got it on the road this week. Went around a corner at a 'spirited' but not 'aggressive' speed and was rewarded by the feelers on the right running board touching down. That'll wake you up! Don't know what the 'lean angle' was, but it was not much! There are 'Invention Patent Idea' places that will take your idea and patent it for you. You make an appointment and walk in, present the idea, and they tell you yes or no. I have gone to them and would do it for sure if I made anything like this. Painless process. |

I would really like to build one... I really like the feature of callibration at any angle And the max lean angle display. Do you mind sharing the source code..? ![]() ![]() |
