Is it the angle of the hinge or the angle of the screen? I assume the latter... my laptop is rarely on a level surface.

- Sharlin 1y agoAt first I wondered why you'd assume the latter – certainly something like a tiny rotary encoder is a simpler lower-tech solution than a MEMS inclinometer. But these days I'm not actually so sure.
- jeffbee 1y agoWithout checking the catalog, I would assume that a MEMS inclinometer is much cheaper in 2025 than an absolute position encoder. Edit: catalog confirms.
- Sharlin 1y agoThanks. Clearly my intuition was out of date.
- joezydeco 1y agoThey're using a pretty nifty differential Hall magnetic encoder, like this one: https://www.novosns.com/en/hall-angle-sensor-4010 https://www.novosns.com/en/hall-angle-sensor-4010 There's a fun Hackaday video using the same type of part in a rotary knob + LCD control. https://www.youtube.com/watch?v=zIrAe23f8sg https://www.youtube.com/watch?v=zIrAe23f8sg
- Sharlin 1y agoCool, thanks!
