Quadrature Encoder Input Meter for Position or Rate

Meter accepts A & B quadrature signals from a linear encoder, shaft encoder, optical encoder or incremental optical encoder to display position, length, angle or rate to 6 places in engineering units.

Quadrature Transmitter, quadrature encoder, linear encoder, incremental encoder

Quadrature Transmitter, quadrature encoder, linear encoder, incremental encoder - Transmitter with 4-20 mA and RS45 outputs for position or rate from a quadrature encoder, linear encoder, shaft encoder, optical encoder or incremental encoder signals. Special circuitry corrects for width of the zero index pulse.

Final block diagram of PiDER 3.0

I decided not to incorporate a Microbit, to reduce load on the batteries and really it would be a step too far.

The trigger pulse for the kicker/cannon/shooter will come directly from one of the Raspberry Pi GPIO pins.

Two 4700uF electrolytic capacitors have been added. One to each H-Bridge 12V power inputs to help with high current draw when the motors start or accelerate rapidly.

The Turn Me Kit + PIC16f1705

Today we'll be showing a demo video of a project our friend @wireengineer put together with a PIC16f1705 and the Turn Me Kit.  The kit is a quadrature encoder with pulldown resistors and allows you to use one with only 5 wires: + / - / Switch / A / B

So we've done an example with the Propeller before: http://tymkrs.tumblr.com/post/52528466585/tymkrs-turn-me-rotary-encoder-breakout-kit

But we wanted to show it working with a PIC, and Peter suggested we show a servo reacting to the encoder being turned.  And sure enough, the following information does just that.  When you turn the encoder left, the servo turns left until it ends.  When you turn the encoder right, the servo turns right until it ends.  And when you push the switch on the encoder down, it centers from whereever it is.
