Word of the Day Display With IoT

“In this Instructable, I’ll show you how you can build a “Word of the Day Display” using NodeMCU Wi-Fi module and a Dot Matrix Display. Instead of word of the day, you can display anything you want (text) from …

Amplifier Tone Control

“Tone control is a type of equalization used to make specific pitches or “frequencies” in an audio signal softer or louder. Bass, treble and volume control It allows a listener to adjust the tone of the sound produced by an …

Arduino CNC Drawing Machine (or the Road to Success)

“This project is based on mostly items which are easy to find. The idea is to take two unused computer disk units and combine them to create an automated drawing machine which resembles a CNC machine. The pieces used out …

Automatic Water Level Controller Using Transistors or 555 Timer IC

“Introduction: Hii Everyone here we are going to learn about Saving the water efficiently. so go through the steps and the Sentences carefully. Water tank overflow is a common problem which leads to the wastage of water. Though there are …

Cheap and Simple Arduino Eggbot

“In this Instructables I want to show how to make a simple and cheap arduino plotter that can draw on eggs or other spherical objects. In addition, soon Easter and this homemade will be very handy”

Computer system transcribes words users “speak silently”

“Electrodes on the face and jaw pick up otherwise undetectable neuromuscular signals triggered by internal verbalizations. MIT researchers have developed a computer interface that can transcribe words that the user verbalizes internally but does not actually speak aloud. The system …

Crash! Scientists explain what happens when nanoparticles collide

“Study results could one day inform the design of new materials for protective gear, energy-harvesting devices and more Helmets that do a better job of preventing concussions and other brain injuries. Earphones that protect people from damaging noises. Devices that …

DIY Motorized Camera Slider

“While documenting some projects at work, we needed a camera slider. Being Makers (and after finding out that motorized sliders are quite expensive) we took the opportunity and designed one by ourself! So, if you need a motorized camera slider …

Double perovskites in environmentally friendly solar cells

“A further step has been taken along the road to manufacturing solar cells from lead-free perovskites. High quality films based on double perovskites, which show promising photovoltaic properties, have been developed in collaboration between LiU and NTU in Singapore. Research …

“Frogs” and “mushrooms” bubble up in quantum fluids

“Quantum fluids may mix in very weird ways, according to new computer simulations of exotic states of matter known as Bose-Einstein condensates (BECs). Far in the future, BECs may enable new kinds of ultra-fast computers. But for now, researchers are …
