Quadrature Encoder

When you're making a load of gears it makes sense to reuse them in different ways.  Here is a mechanism that is not only an Quadrature Encoder, it also serves a 1:2 ratio and a right angle drive without resorting bevel gears.  This will help us keep the vertical height of the compiled planetary trains from growing too quickly, as well as, provide feedback to the host machine whilst programming and debugging.  

The two slotted discs are a half tooth out of phase and sandwiched between two interlocking compound gears to balance out the forces. 
This interface needs a catchy acronym in the spirit of JTAG or ICE.
 ***Update:  The catchy acronym for this interface is Q.E.D. for Quadrature Encoder Device, or quod erat demonstrandum.

  1. Hi Brent! How are actually manufacturing all this stuff? You have your own CNC?

  2. This is indeed a CNC laser cutter! It can vaporise 10mm solid wood or 5mm 3-ply plywood easily. You know my orbital number.
