New sensor detects rare metals used in smartphones

“A more efficient and cost-effective way to detect lanthanides, the rare earth metals used in smartphones and other technologies, could be possible with a new protein-based sensor that changes its fluorescence when it binds to these metals. A team of …

Object Tracking Camera Slider With Rotational Axis. 3D Printed & Built on the RoboClaw DC Motor Controller & Arduino

“This project has been one of my favorite projects since I got to combine my interest of video-making with DIY. Ive always looked at and wanted to emulate those cinematic shots in movies where a camera moves across a screen …

Plant Monitor Using ESP32 Thing and Blynk

“The goal of this project is to create a compact device to monitor the conditions of a houseplant. The user will be able to check the soil moisture level, humidity level, temperature, and the “feels-like” temperature from anywhere on a …

Pseudo random number generator

“The pseudo random generator made from transistors, 4000 and 74HC series ICs. Simple 3 bit pseudo random generator with graphical presentation, made from few transistors and 4000 and 74HC series ICs.”

Remotely Control Home Electronics with PIC-IoT WG

“This tutorial uses a Relay Click and the PIC-IoT WG to control a fan, lamp, or any other wired device from the cloud. This demo was created for Microchip’s booth at Google Next 2019. Attendees in San Francisco …

RFID NFC Tap and Go Ring for Credit Card Payment

“The idea behind this project is that if you have an RFID credit card, you can tell your bank that you need a replacement card, then once you have that second card, you can dissolve it in acetone, take out …

Scientists develop low-cost energy-efficient materials

“An international team of scientists from the National University of Science and Technology “MISIS” (NUST MISIS), Tianjin University (China), as well as from Japan and the United States has developed new energy-efficient iron-based alloys which combine high mechanical and magnetic …

SCOTT - Scientific RPN Calculator with OLED display and ATTINY85 microcontroller

“To examine how much “calculator power” a simple microcontroller like the ATTINY85 is able to perform was already the intention of ScArY (www.github.com/zooxo/scary). Unfortunately ScArY was based on a premanufactured development board (QYF-TM1638) and was …

Semiconductor scientists discover effect that was thought impossible

“A physical effect known as superinjection underlies modern light-emitting diodes (LEDs) and lasers. For decades this effect was believed to occur only in semiconductor heterostructures — that is, structures composed of two or more semiconductor materials. Researchers from the Moscow Institute …

Snake-inspired robot slithers even better than predecessor

“Programmable kirigami metamaterials enable responsive surfaces and smart skins Bad news for ophiophobes: Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new and improved snake-inspired soft robot that is faster and …
