Digital Tilt Sensor (Arduino Compatible)

“Sensors are the best thing to get started with DIY electronics, you can get a wide variety of sensors, each suitable for one or more tasks. The arduino is compatible with a variety of sensors and I’m going to …

TV Remote Control based on Head Movements

“A low cost, open-source, universal-like remote control system that translates the user’s head poses into commands to electronic devices. The project presents a proposal of an open-source, low cost universal remote control system that translates user’s head poses …

Building a Circuit to Detect High Frequencies: The Bat Detector!

“Bats come out at night and can be difficult to spot—but with this bat detector, you will be able to track them down! While some bats do make audible clicks, most produce inaudible clicks that are between 20kHz and …

DIY Motion-Activated Sink: How to Make an IR-Controlled Tap

“Despite sinks being critical to hygiene, manual taps are still pretty nasty and so newer “automatic” sinks are used in many public spaces. In this DIY Hacking project, we will create a simple IR water dispenser!”

Do-It-Yourself Insect Detector with an Electret Microphone and PIC18F1220

“If you, like most, are irritated by fly insects or have a fear of being stung by a spiteful wasp then this circuit is for you. In this project, we will create a circuit that can detect flying bugs that …

Microcontroller Action Potential Generator

“Here I demonstrate how to use a single microcontroller pin to generate action-potential-like waveforms. The output is similar my fully analog action potential generator circuit, but the waveform here is created in an entirely different way. A microcontroller is at …

Coilgun Without Massive Capacitors

“Coilgun is like a slingshot from the future. Whilst it’s kind of useless it’s a lot of fun to play with. I’m going to show you how to build one without using huge and expensive capacitors. My …

Retro Project – Audio Mixer For Cassette Recording

“The digital age has seen a tremendous transformation ranging from the rapid increase in hard drive space and the speed of processors. However, some computer users in the past had to rely on more ancient technology to save and load …

Sound-Activated IoT Alarm with ESP8266 and RIOTOUS

“The IoT has created an industry that is rapidly growing and connecting even the simplest circuits to the internet allows for data gathering and home automation. In this DIY project, we will look at an IoT platform called RIOTOUS to …

Digital Vibration Sensor Using LM358

“Working with sensors makes electronics better and easy to work with, there are thousands of sensors to choose from and designing sensors would make for cool DIY projects.This instructable will be a part of a series of instructables in …
