Some design work (Trilidar mouse)

A project log for ToF ranging sensor trackpad mouse

Why buy a mouse when you can make one that is worse?

Pronounced "try-lid-ar" heh

I'm largely basing everything off the VL53L0X's beam pattern (25-30 deg) and that I'm using 3 of them.

I ordered some more... although I may use the different brands to get a difference I2C address vs. using say SPI or a microcontroller between the sensors/pi.

Will print tomorrow/do wiring and program testing.

I'm hoping there are no obvious gotchas that make this not work.

I initially thought 25-30 deg is massive but it's not... you still need a large diameter ring. The effective area I'm looking at with a 6" outer ring is a 2.5" inner ring (based on dead zones).
