Arduino Mega Chess on TFT display

Story After some my Arduino project remains unclaimed touchscreen, so I decided to realize my chidhood dream to create a chess program. After a couple of months it wins me, but it is not big deal because i do not have any chess rating, just amateur. This project uses Arduino Mega 2560 because of lack of operative memory on Uno, 2.8 inch touchscreen, passive buzzer, and about 2000 lines of code. Program uses ...

Recycled Motherboard RC Quadcopter

My university had a bunch of old server motherboards that were headed to the dumpster. I decided to see the feasibility of turning them into something useful! Go ahead and grab the attached pdf plans, print them out full size, and build your own! Step 1: Prepare the Motherboard Pop in your earbuds, turn up some tunes, and spend some quality time with your heatgun. If you have a sacrificial toaster oven big ...

How to Make an Entire Drone/Multirotor and Camera Gimbal Using Laser Cut Parts

the photo you see was taken from my first ever copter which i built in 2 hours, what i had not mentioned was my first copter used a laser cut frame i designed and produced whilst in school.This difference between this post and my other about building multirotors is this is mainly to do with designing a custom frame, however i thought rather than  post links to the next tutorial, i would include it both ...

World’s Smallest MEMS Micro-Loudspeaker Saves 80 Percent More Energy

STMicroelectronics along with the audio company USound has created the first MEMS (Micro ElectroMechnical Systems) micro-loudspeaker based on semiconductors. It’s the smallest loudspeaker in the world, but it can produce a powerful noise. MEMS makes it possible. The speakers are being presented at CES 2018 in Las Vegas. In the audio world, the electromechanical capabilities of MEMS have only been used to bu ...

Low-Cost, Arduino-Compatible Drawing Robot

https://youtu.be/Uo2aUUNhdKs I designed this project for a 10-hour workshop for ChickTech.org whose goal is to introduce teenage women to STEM topics. The goals for this project were: Easy to build.Easy to program.Did something interesting.Low-cost so participants could take it home and continue to learn. With those goals in mind, here were a couple of the design choices: Arduino compatible for ease of prog ...

OpenMV- Machine Vision for Beginners

MV is the ability of a computer to see using analog to digital conversion and digital signal processing. The key characteristics that make a machine vision module better are sensitivity and resolution. These systems allow machines to see a broader spectrum of wavelengths such as x-rays, infrared or UV light. Nowadays, it is mainly used for object recognition, signature identification, material inspection, m ...

Arduino Watch Sport

I apologize if you find spelling errors or nonsensical text, my language is Spanish and has not been easy to translate, I will improve my English to continue composing instructables. In today's technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated to implement, thanks to these technological advances are now able to design and ...

Researchers Demonstrate New More Efficient FET By Implementing Negative Capacitance

A group of Researchers from Purdue University in Lafayette, Indiana demonstrated the effect called negative capacitance by making a new type of more energy efficient transistor. This new kind of Field Effect Transistor (FET) proves a theory introduced in 2008 by Supriyo Datta, the Thomas Duncan Distinguished Professor of Electrical and Computer Engineering, and Sayeef Salahuddin, who is a professor of Elect ...

Simple LiDAR Using the Laser Rangefinder Uni-T UT390b, Arduino and Turbo Pascal

Some days ago I bought a laser rangefinder (Uni-T UT390b, f.e. http://www.dx.com/de/p/uni-t-ut390b-45m-laser-dist...) to realise a simple LiDAR. The rangefinder has an accuracy of +/- 2mm and is able to measure distances up to 45m. This will be enough for my living room ;-) You'll also need: * Arduino Mega (because of more than one Serial Outputs) * 2 Servos * Servo tilt (f.e. http://physicalcomputing. ...

Lie Detector and Biofeedback Arduino Based

This tutorial will explain how to build a machine for biofeedback. But first a bit of theory. What is biofeedback? [Font: Wikipedia | https://en.wikipedia.org/wiki/Biofeedback] Biofeedback is the process of gaining greater awareness of many physiological functions primarily using instruments that provide information on the activity of those same systems, with a goal of being able to manipulate them at ...
