Speeding up the machine learning process

“A new approach for training algorithms makes the machine learning process faster and more accurate. At a time when big data reigns supreme, training machine learning algorithms to perform certain tasks is often costly and time-consuming. At KAUST’s Visual …

This flat structure morphs into shape of a human face when temperature changes

“New structural design could lead to self-deploying tents or adaptive robotic fins. Researchers at MIT and elsewhere have designed 3-D printed mesh-like structures that morph from flat layers into predetermined shapes, in response to changes in ambient temperature. The new …

This is how a “fuzzy” universe may have looked

“Scientists simulate early galaxy formation in a universe of dark matter that is ultralight, or “fuzzy,” rather than cold or warm. Dark matter was likely the starting ingredient for brewing up the very first galaxies in the universe. Shortly after …

Using High Energy Density Material in Electrode Design Enhances Lithium Sulfur Batteries

“Lithium ion batteries aren’t keeping up with energy demands from higher power electronic devices, electric vehicles and smart electric grids. To develop higher capacity batteries, researchers have looked to lithium sulfur batteries because of sulfur’s high theoretical capacity …

32 Band Audio Spectrum Analyzer Using Oled Display And Attiny85

“Visualizations are an important part of a music player. They provide the user with something to feast their eyes on especially when the music has no video. For today’s tutorial, we will build a visualization device, capable of providing …

Aquarium Auto Lighting System

“In this DIY guide I will show you how to make your own Arduino aquarium auto lighting system. In this project I decided to make my own PCB that is based on Arduino UNO microcontroller - Atmega328p. Bellow you will find …

Arduino Audio Meter

“The Arduino Audio Meter is a programmable guitar pedal that works with the Arduino UNO board. It is able to read the incoming audio signal and create effects on the four 8x8 LED matrices. The project is Open Source and …

Arm Mbed OS 5.14 released

“In the three years since we released Mbed OS 5, we’ve focused our engineering efforts on adding the feature set an IoT operating system requires. We’ve invested in connectivity, security, device management and storage. That investment has paid …

ATtiny Running Lisp

“This project describes how to run programs in the high-level language Lisp on a Microchip ATtiny 3216 microcontroller costing just over a dollar. It uses my Lisp interpreter for microcontrollers, uLisp.”

ATtiny85 RF Remote Control

“As I mentioned in a previous Instructable I recently started playing with some ATtiny85 chips. The initial project I had in mind was to make an RF remote control that could operate on a coin battery. I needed to go …
