I am glad you can use it. (I was looking at all the Catlin Clark stuff and the politics and your comment pulled me back to the reality of why I love working with machines, LOL.)

Lol the one with Adam apple? 😅 i’m trying to use it for measuring an e-bike motor power. I want to make it can do a steady state tuning

@@manray8513 There are so many of them out there! If you just want to do steady state, you might be able to avoid the whole data acquisition stuff and instead just print your sensor values to your PC monitor using some commands like this: // print the results to the Serial Monitor: Serial.print("sensor = "); Serial.print(sensorValue); Serial.print("\t output = "); Serial.println(outputValue); Then loop it with a delay between loops. That would still show in real time for you. Coming up with a decent brake to slow the motor and read the force will take some creativity but you might be able to do it right on the bike. If you like to tinker, this will be fun.

@@1227air500 yeah i was thinking about put the brake on the bike, maybe make a hub and using some car brake to do it. I’m gonna modify this to output a digital potentiometers (for the ESC throttle) and geared stepper motor to pull the brake for the load so i can just input the RPM then the dyno doing it stuff. There’s one from Dirty Elbow garage for the reference

@@manray8513 Yes, I watched that Dirty Elbow video a while back. He came up with a nice set-up. But before you go that route of a computer controlled load, just try it manually.That way you'll get a feel of how the load needs to vary throughout your test. You might be surprised at how much you can do with a manually controlled load.

This is Fantastic , I was thinking to make this sort of project but could not find proper practical example.

Go to the arduino.cc forum and search for the topic Easy Prony Brake Dyno for Small Motors and Engines that was started Mrch 25, 2024 by Lloyd-ss. It is all there.

Hi, Is the program available for download ?

I am preparing complete documentation to post on the Arduino.cc forum in the next few days. It will have a PL. schematic, Arduino program and Excel program. What level are you at with electronics, Arduino, Excel, mechanical, etc? This program is also suitable for an inertial dyno in addition to the prony brake/energy absorber type shown in the video.

Yes. The question was already asked here by @mitchchcruz. That answer tells you where to find it on the Auduino forum.
