I needed a tacho/RPM display for a CNC spindle. I decided to use an Arduino Micro and OLED display with a reflective LED/Photo transistor as a sensor. Since powering up, a clock can display the total ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

The purpose of this tool is to measure any rotation speed with the same accuracy as a commercial product, it can also blink at afrequency defined by the user to match the roatation of anything up to ...

This repository contains the hardware schematics and software code needed to build a jogwheel based pendant controller to interface to Marlin / Arduino controlled 3D printers & CNCs The pendant uses ...

An interesting Arduino project has been published to the Instructables website showing how an Arduino CNC shield and controller has been used to create an awesome 3 axis Arduino CNC plotter. The ...

The Arduino PCB Ink Plotter CNC Machine is a DIY project that features a arduino running GRBL CNC firmware. In this project, it uses a marker that is suitable for plotting or marking the PCB for board ...

This homemade CNC machine is the second version which uses mostly off the shelve parts where every part is allowed for some adjustments and the different design makes it easier to be built. The main ...

Young maker and Arduino enthusiast Nikodem Bartnik has created a fantastic Arduino CNC machine by converting a Dremel cutting tool and using a selection of 3D printed parts and aluminium profiles.

Once, long ago when magazines still existed, I bought a copy of Popular Mechanics. Inside was a guide on how to build a robotic lawnmower. Now this was back in the 1980s so it wasn’t a very complex ...

[Sebastian] and [Stefan Shütz] had a ISEL EP1090 CNC machine at home, sitting unused, and they decided to bring it to life. With pretty good mechanical specs, this CNC looked promising – alas, it was ...

Grbl_ESP32 CNC development board is a breakout board for NodeMCU 32S board that also takes three stepper motor drivers, and designed to run Grbl open-source Arduino firmware to control wireless CNC ...
