Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

Rather than keep adjusting the cooler’s power manually, he automated it by installing an Arduino Pro Micro as a controller in the cooler and writing a Rust controller application for his computer.

Inside is Arduino Pro Micro and a PMW 3389 optical sensor on a breakout board. [Ben] was going to use flexible 3D printed panels as mouse buttons, but then had an epiphany — why not use keyboard ...

TMC2209 Stepper Motor Control Overview Stepper motors are commonly used in automation due to their ability to move in precise, discrete steps. However, to drive them efficiently, we need a motor ...

Learn to build an RFID based attendance system using Arduino with step-by-step instructions, circuit diagrams, and complete code. This $35 DIY project replaces expensive commercial systems with ...

Using a Drude-based polarizable model, we investigate the liquid–vapor interface of hydrogen fluoride (HF) via molecular dynamics simulations. The interface displays a complex morphology with ...

This paper presents a simultaneous bi-directional (SBD) 4-level I/O interface for high-speed DRAMs. The data rate of 4 Gb/s/pin was demonstrated using a 500-MHz clock generator and a full CMOS rail-to ...

In this paper, based on the classical "two-frame difference method" and "three-frame difference method", an improved pedestrian detection scheme based on "three-frame difference method" is proposed.

Through the use of molecular dynamics simulation, we examine the structural and transport properties of water and hydronium ions at the interface of a Nafion polymer electrolyte membrane and a vapor ...
