Abstract: Braille literacy is critical for individuals with visual impairments, yet the high cost of refreshable braille displays (RBDs) remains a barrier to accessibility in educational settings.

In the evolving landscape of precision sensing, contactless potentiometers are quietly redefining what reliability looks like. By replacing mechanical wear points with magnetic sensing, these devices ...

The Wireless Stepper Driver is a compact and efficient motion control system designed to control stepper motors over Wi-Fi. It is built using the TMC2240 stepper driver and an ESP32-S3 microcontroller ...

In a nutshell: Canadian hardware maker Ploopy is now accepting pre-orders for its latest input device. The Ploopy Knob is a 3D-printed, open-source rotary encoder featuring a high-precision sensor ...

Warning: This library is not tested with hardware yet. So use with care, feedback welcome. ECRFS is a library for the ERCF 1 05SPI 360 Z rotation encoder. This devices decodes 360.0° in 16384 steps ...

Scrolling has become an essential part of our digital lives, whether it's navigating through lengthy datasheets, coding, or simply reading articles. Yet, the act of scrolling—endlessly flicking a ...

This is project of Arduino based wheel controller with force feedback. To configure the controller parameters, you need to use the graphical interface AFFBWheelGUI 8 axes: steering(X), accelerator(Y), ...

[Igor] has an AS5600 magnetic rotary encoder chip on a breakout board. Normally, you’d think that was an easy device to work with since it has an I2C interface. But [Igor] wanted to do it the hard way ...

The PD Stepper is a NEMA 17 integrated stepper motor driver and controller board powered by USB power delivery that combines an ESP32-S3 wireless microcontroller, the Trinamic TMC2209 ultra-silent ...

NEMA-17 steppers are (almost) a dime a dozen. They’re everywhere, they’re well-known to hackers and makers, and yet they’re still a bit hard to integrate into projects. That’s because the motor alone ...
