ESP32 Stereo audio spectrum visualizer with amplifier

“Make audio come to life. Get the mood on and “See the music” suitable for gaming and music. I was inspired to created this project one day once I saw a YouTube recommendation for Scott Marley’s video for making …

ESP8266 NodeMCU Based IoT Alarm Clock With Blynk

“Hello and welcome to our instructable about using ESP8266 NodeMCU Based IoT Alarm Clock With Blynk. This project is made by two students named Valentino Kevin and Ryan Jonathan from BINUS taking a degree in Computer Engineering, and in this …

Extend an Arduino with a CF Card or IDE Drive

“Interface an Arduino Mega with an IDE drive or CF Card! It is easier than you might have thought! The built-in 1 or 4 kilobyte EEPROM memory of an Arduino is quickly used up if you want to permanently store …

First glimpse of polarons forming in a promising next-gen energy material

“These fleeting disruptions, seen for the first time in lead hybrid perovskites, may help explain why these materials are exceptionally good at turning sunlight into electrical current in solar cells. Polarons are fleeting distortions in a material’s atomic lattice …

Fungus as a sound absorber

“As healthy and tasty as mushrooms might be, they are good for much more than just the dinner plate. The Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT has now teamed up with the Fraunhofer Institute for Building Physics …

Project  Getula

Getula

“Morphing clock A Bicycle chain lying randomly on the street gave inspiration for this art work. The simple idea of creating numericals out of a continuous chain quickly turned into a complex beast. The chain is made out of 3d …

Handheld BASIC Computer

“This Instructable describes my process of building a small handheld computer running BASIC. The computer is built around the ATmega 1284P AVR chip, which also inspired the silly name for the computer (HAL 1284). This build is HEAVILY inspired by …

Headphone Amplifier For DAC Converter

“This is a headphone amplifier project for audio digital-to-analog converters (DACs) with differential voltage outputs. This circuit converts the differential voltage output of the DAC to a single-ended, ground-referenced signal and provides the additional current necessary for low-impedance headphones. Project …

HexMatrixClock

“Hexagons are cool — they have six sides, they tile a plane, they have a structure like the carbon atoms in graphite, each cell has six neighbors, and there are six cardinal directions. But mostly, they are not square when so …

High Accuracy Current Sensor with 400Khz Bandwidth using ACS37002

“This is a high accuracy current sensor project build using ACS37002 IC from Allegro, which is a fully integrated Hall-effect current sensor with 0.85mOhms integrated conductor. A fast overcurrent alert output, programmable gain settings and analog linear voltage outputs …
