    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Have some questions: Are you saying a 1K pullup to the LM339 Vcc? Also, not understanding what you meant to do with the diodes.

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    LiteYear the tacho is definitely a more simple solution and it has been brought up. Like you said, the Arduino route may be easy for electrical/comp guys, but I'm considering this a good way broaden my own horizons away from composites and solid modeling! The display may be a problem at first...

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Thanks OperaHouse again. I have started writing some baseline sketches and look forward to using the Uno when it comes in, even though I'm starting at a crawl. VE1BLL, testing will be done in a homemade turbulent flow wind tunnel and in real-world environments, measuring the wind speed, voltage...

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    I'm moving towards an LCD 16x2 shield for the UNO. Already stock to fit and easily programmable. It seems as simple writing an Anduino program counting the sync cycles from the motor, or converting volts to RPM itself, then displaying it on the LCD. Adding a scrolling line to the program with...

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Well the volt/amp meter is easy by all means; showing RPM is still not getting through my skull.

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Thanks OperaHouse. I'll definitely look into this, the Uno looks like everything we need. Still would like to put a voltage, power, and speed meter(s) on the controller box itself, for instantaneous readings.

    How to manage different lengths of a bulk part?

    It depends on how the parts will be used, how many will be made, and your company drawing standards. Are you manufacturing multiple booths, how are the booths being fabricated, who is fabricating, etc. Generally speaking, if the bulk product is to be cut or fabricated to unknown lengths or...

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Right, should have thought of that before! I have the pole pair number of the motor, and I understand it's just calibrating to count the number of sync cycles per rotation. I've seen programmable rate meters through some prelim searches. Is this a good street to go down, and if so any product...

    VE1BLL yes we've selected and tested a small anemometer aft of the nacelle.

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Great suggestions, I would like the ability to monitor through the motor itself. Now the question is how one picks up on those signals when not providing power to the motor, and how to display/monitor it. Any recommended sources for parts or information that could guide me? Again appreciate it.

    Designing Encoder/Tach Circuit for Digital Display and CPU Interface

    Mechanical guy tackling electronics here. I'm looking to design and fab a consumer grade personal-use wind turbine with portability and cost being main design constraints. My main goal is to have a charge controller box that displays voltage from the DC motor, as well as the motor shaft RPM, on...
