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 ...

In 2006, Harley-Davidson (H-D) made one of its most pivotal mechanical updates in years. It was a shift (pun intended) that saw H-D move from a five-speed to a six-speed transmission, introduced with ...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications—such as robots and processing and packaging machinery—and consumer ...

Abstract: This research studies the implementation of Proportional-Derivative (PD) and Model Predictive Control (MPC) approaches embedded in an industrial Programmable Logic Controller (PLC) to ...

Like the iPhone 16 series, all of Apple's latest iPhone 17 models include a new Camera Control button (located on the lower right-hand side when holding the phone in portrait mode). The button aims to ...

As the saying goes, nothing can be said to be certain, except death, taxes, and the never-ending inventiveness of clock hacks. No matter how tried and proven a concept is, someone will always find a ...

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 ...

SAN FRANCISCO (KGO) -- Drivers may hate it, pedestrians may love it, but the use of speed cameras on San Francisco city streets is now a reality. On Thursday, some of the 33 new cameras turned on.

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

This library uses a PCF8575 to read the pulses of a rotary encoder. As a PCF8575 has 16 lines up to 5 decoders with a switch can be read over I2C. The PCF interrupt line can be used to detect changes ...
