“Sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller. It can detect metal coih at distance of 30cm, and big metal object at distance of more than 80 cm. Supplies: - STM32F103C8 microcontroller board - WS2812 Addressable LED Strip …
“EPFL engineers have found a way to control the interactions between excitons – quasiparticles that may one day transport data and replace the electrons in electronic devices. The engineers’ method involves applying an electric field to a two-dimensional (2D) semiconducting material …
“Universal remote control for small vehicles or robots, using the ESP-NOW-protocol, which is similar to the low-power 2.4GHz wireless connectivity. Up, down, right, left, button. Small, simple, with control LED. Basic knowledge for Arduino IDE is required …
“This is a clock with a floating display based on Aerial Imaging by Retro-Reflection (AIRR). The numbers from individual LED panels are projected using a beamsplitter and a retroreflective foil. For the observer the numbers seem to float in the …
“Evidence left in rocks is leading scientists to rethink what watery environments looked like on ancient Mars. New images taken by NASA’s Perseverance rover may show signs of what was once a rollicking river on Mars, one that was …
“Engineers show that a jellybean-shaped quantum dot creates more breathing space in a microchip packed with qubits. The silicon microchips of future quantum computers will be packed with millions, if not billions of qubits – the basic units of quantum information …
“Greetings everyone, So here’s something fun: aMANGA READERmade from scratch with custom PCBs and 3D printed parts. The brain of this project is an ESP12F Module, which is an ESP8266-based WiFi Module connected to an ILI9225 LCD Screen …
“Close communication between optics designers and manufacturers can help prevent problems Although optical components such as lenses are traditionally spherical in shape, freeform optical components, which have little to no symmetry around the optical axis, are becoming more common. Freeform …
“The purpose of this project is to build a portable device, 3D printed, using an Arduino microprocessor and a mobile app, that can measure the speed of sound in gases and use this data to identify them. The $ speed of …
“ATtiny13A Resistive Soil Sensor for Duck Lovers Moisture-Duck helps you keep track of your plants’ soil moisture and alerts you if they need watering. It utilizes the resistance measurement technique to gauge soil moisture levels. Two probes, in combination with …
