WiFi – IR Gateway a.k.a. Give your Dumb (Old) Devices the Smarts!

“Some time ago I also completed this project that I never got around to publish. This project is a WiFi-Infrared gateway. I am aware that such commercial products exist, but at the time I needed one for my home the …

WiFi NodeMCU ESP8266 Google Clock

“A simple easy WiFi clock using “Google” timestamp, with temperature and humidity. Oct2020 update: bug fixing and automatic brightness I made several clock with arduino but was looking simple, easy, light, synchronized in real time with internet clock different than …

Winners and losers of energy transition

“Accounting for multiple social aims other than costs is critical for transitioning from fossil fuels to renewable electricity. A new study by UNIGE proposes a viable compromise. The European Green Deal aims to drastically reduce greenhouse gas emissions in the …

Write in Braille With B.E.E! - DIY Braille Embosser

“Braille as a form of communication has always interested me greatly- so when I saw a contest about making Tools, I took it as an opportunity to develop an idea that I had been thinking about for the past year …

0 to 10 V Adjustable Lab Power Supply with Current Control

“The circuit presented here is a very simple and easy to build Lab Power Supply. The output of this power supply is adjustable from 0 to 10V DC, and it has current limit control up to 3A. Two Trimmer potentiometers …

3D Printed Arduino Powered Quadruped Robot

“From the previous Instructables, you can probably see that I have a deep interest for robotic projects. After the previous Instructable where I built a robotic biped, I decided to try and make a quadruped robot that could imitate animals …

A new interpretation of quantum mechanics suggests that reality does not depend on the person measuring it

“For 100 years scientists have disagreed on how to interpret quantum mechanics. A recent study by Jussi Lindgren and Jukka Liukkonen supports an interpretation that is close to classical scientific principles. Quantum mechanics arose in the 1920s – and since then …
