A servo-driven lead screw using Arduino to calculate proper spindle and lead screw speeds for cutting English and metric threads with VFD.
A simple tool to measure speeds of rotating objects
Build you own Arduino-based laser tachometer for around $10 and learn something while doing it!
Flashy LED decor lights that respond to your bike's motion.
A very simple way to make a tachometer where the result is displayed on an OLED display in the form of an RPM number and a progress bar
My Tachometer failed so I replaced the original mechanism with a stepper motor, driver board and Arduino pro micro
This is a small, photoresistor-based tachometer for use on several different development boards (whatever you might have laying around).
We use tachometer in our industry. So I'd like to make some tachometer to check it in home with available resource.
You can read the RPM of the washing machine motor. In the display the average value and the status of the motor is shown
In this project, GreenPAK SLG46533V is used to design an optical contactless tachometer with the use of an infrared sensor.
Optical encoder is a device that is used to measure the speed of a slotted disc in RPM.
The device detects the difference between the given engine speed and the speed desired by the user.
Growth opens opportunity, but not only to the good builders and investors but also to bad guys
