“TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100mA - 1000mA) and an OLED display for monitoring. Hardware Power Connectors The device is equipped with a Micro-USB and a USB-C connector for …
“Plastics are one of the world’s largest polluters, taking hundreds of years to degrade in nature. A research team, led by YSE professor Yuan Yao and Liangbing Hu from the University of Maryland, has created a high-quality bioplastic from …
“Colossal voltage results from interplay of material’s topology and strong electron correlations in a uranium-cobalt-ruthenium-aluminum alloy New research has demonstrated that a magnetic uranium compound can have strong thermoelectric properties, generating four times the transverse voltage from heat than …
“The Casio CP-10 is a neat calculator that has a thermal printer attached. The calculator also has a built-in clock and can do useful tasks such as printing this month’s calendar. The date rang eis also useful as …
“A system that gives my bike front and tail lights, a turn signal, and a speedometer, all in a clean and simple design. Hello! My name is Collin Wentzien, and I am a 15 year old maker and electronics enthusiast …
“This project is about building an adjustable high voltage generator (DC) from a low DC voltage supply. The voltage supply can range from 5V to over 25V (I use a 9V supply). Higher voltages can require heat dissipators attached to …
“A cute PCB alpaca with a rainbow tail and glowing cheeks. I’ve recently heard of the Micronucleus bootloader for the ATtiny85 and I wanted to try it out, so I designed this quick alpaca ATtiny85 dev board, which can …
“Metal-insulator transition (MIT) driven by many-body interactions is an important phenomenon in condensed matter physics. Exotic phases always emerge around the metal-insulator transition points where quantum fluctuations arise from a competition among spin, charge, orbital, and lattice degrees of freedom …
“”Save for a rainy day,” as the saying goes. But that doesn’t mean saving money has to be boring and analog. Bring your coin box into the 21st century with this awesome DIY Arduino-powered solution. Before you begin building …
“A tiny frequency meter built using the ATtiny1614 microprocessor. Over the years, I have build a number of audio oscillator circuits using discreet components (no microprocessors). While these produce good quality sine waves, the frequency of the output is usually …
