Built my own high resolution (500 CPR) spinner!

(1/2) > >>

Major Rock Hardy:
See pictures below.  Machined out of 2" square aluminum tube, brass, and stainless for the shaft (1/4").  Yes I did the machining.

Sensor is a Avago AEDB-9140-A06 with matched 500 CPR codewheel.  Just hooked it up last night to my Opti-PAC and it works great!  Gotta give credit to Whammoed for the 2" aluminum square stock idea (http://www.nicemite.com/Gyramite/images/02Prototype.JPG) - although I kinda reversed the design.

Here is a link to the sensor's homepage in case you want more info:

Sensors run off 5V (supplied by OptiPAC), just require a couple 2.7 K resistors as pull-ups.  Only tricky thing to watch out for is that the encoder wheel is VERY delicate and soldering .050" spaced contacts sucks.  Ok, here's your pics:

Sweet!
Good work...
What did the sensor cost? I dont see a price anywhere on the website.

Thanks for the compliment!

I was actually able to get samples (free).  This was over a year ago so I don't know the current status of sample-getting.

Also, if anyone's interested, I will post the blueprints.  I am working on rev2 right now because the spacing between the grooves on the shaft allows a bit too much vertical slop.  The codewheel stays within the gap of the sensor module but just barely.

Looks really clean.  Nice work, I've though about doing something similar, but with just a mouse hack.  Maybe your work will help get me inspired.  Thanks for sharing and I bet that the plans would be appreciated by somebody, if not now than sometime down the road.
