Some simple code to monitor the filament feed to a 3D printer. When it is detected that the filament is no longer moving (but the feeder motor is moving), the control pin will be triggered. I wrote ...

This project is a DIY simple optical rotary encoder with 180 points per rotation and bi directional detection that you can make at home with a 3D printer. This Arduino Rotary Encoder is intended to ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Arduino 3D Printer project is a DIY 3D printer design based on an arduino board. It features RAMPS 1.4 shield and Arduino Mega 2560 that handles majority of the 3D printer components. It has an ...

A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

You just made payment to a restaurant and received a small bill or dispensed cash from an ATM and received the transaction receipt. These receipts are printed using a Thermal printer or receipt ...

There is by no means a shortage of teams working on low-cost 3D printers. Kickstarter is absolutely overflowing with them. But, as many of those teams quickly realize, shipping hardware is hard. A ...

Arduino, maker of the open source hardware platform of the same name, is teaming up with a startup called Sharebot to sell a 3D printer for about $1,000. Announced today, Materia 101 will be ...
