Serial Number Rotary Watches

Optical mouse sensor as rotary encoder ATM, Optics and DIY Forum. This is where Im currently at. What I really need is some way to manage this error so it does not accumulate over time. My first thought was to use a mechanical or magnetic switch to zero the encoder counts once every rotation. I would take the scope through an entire 3.

As long as the optical tracking was good enough to make sure I could tell which one of these marks I was crossing, I could use them to snap the encoder readings to the correct value each time one was encountered. Basically every time the switch is triggered, snap the encoder value to whichever value is closest to the current reading. I know that the optical tracking is pretty good in a general sense, its pretty accurate over shorter distances, so I would expect fairly low error between the major snap points. Even if I moved the scope back and forth between two snap points and built up error, it would be easy to just push the scope a bit further, crossing a snap point, to recover full accuracy. So my current plan is to use an IR optical sensor a line sensor for robots to detect small painted black lines on the inside of my bearing surface. Uncharted 2 Pc Completo here. Probably 8 of them spaced 4. I can figure out the best way to measure the angles on a large circle accurately. Im soon going to design an 3d printed enclosure to hold the two sensors the mouse sensor, and the line sensor securely and mount it to the rocker box. Ill do just about the same thing for the alt sensor, it will be looking up at the bottom of the altitude bearings and at black marks on the side of the bearing. JPG' alt='Serial Number Rotary Watches' title='Serial Number Rotary Watches' />I wanted to post because I thought some people might be interested, and Ive always received good feedback and suggestions from this group. Maybe I should just go back to the tried and true rotary encoders It does feel like Ive sort of come up with a duct tape and chicken wire solution, with a bandaid to fix the poor tracking of the base sensors. I think it might work, and would be pretty accurate. I cant help thinking I might be on the wrong track here. Mazdas been working on a new rotary engine for pretty much forever at this point, though since the demise of the RX8 in 2012, its been car vaporware, salivated. Watches.
