While we’re 100 years past Edison’s fear, uncertainty, and doubt campaign, the fact of the matter is that DC is a bit easier ...

Abstract: In this paper, a high-precision rotary encoder based on a sinusoidal transmissive pattern (STP) is proposed for detecting shaft rotation. The STP disk can be realized by coating bell-shaped ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...

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 ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

Warning: This library is not tested with hardware yet. So use with care, feedback welcome. AMT25 is a library for the AMT253D-V and compatible rotation encoders. This devices decodes 360.0° in 4096 ...

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 ...

Many hobbies seem to have a subset of participants who just can’t leave well enough alone. Think about hot rodders, who squeeze every bit of power out of engines they can, or PC overclockers, who ...

Electrical contacts in mechanical pushbutton switches often make and break contact several times when the button is first pushed. A debouncing circuit can remove the resulting ripple signal to provide ...

The superconducting diode effect allows for nonreciprocal, dissipationless transport. It has the potential to enhance transfer current efficiency compared to the traditional semiconducting equivalent ...
