So, heres what you (could) do. Go with the rack and small gear, possibly gear this up too* then use a mouse wheel sensor. Mouse wheels (and mechanical mouse movement sensors) work by shining a light through a slotted disc onto 2 slightly offset photo diodes/transistors. By monitoring when each opto...

How accurate do you need? Have you thought of painting (sticking a printed lable) onto the shaft (axle, not axe btw), then using opto sensors? Is there something already attached to the axle that you can measure. We really need much more info than you have given, a picture would be great. Hi guys a...

Hi all ! Mi problem is currently to make an accurate measure of the angular orientation of a 150 mm axe. I've already made some test using a GY-80 IMU : it works fine but I finally need more precision than I thought for my functionnal use case. I can't deeply modify the existing mechanism. So I wond...

Hi ! I'm currently integrating an HMC5883L included in a GY-80 IMU in a personnal C++ sky tracking project. If I understand what you want to do I think you should fusion the magnetometer data with data from other sensors integrated on the same IMU. To be brief, an accelerometer allow you to detemine...

Bonjour Je suis totalement novice en Raspberry mais j'en ai pas mal entendu parler. Je cherche aujourd'hui à réaliser un montage pour lequel je me dit que son emploi serait adapté. J'aimerai être capable de connaitre assez précisément (je dirai au cm près maximum) l'emplacement d'un "point" dans l'e...
