Robotic Trombone: The RoboTrombo Music Machine

“Because we need to prove there are still things people do better than machines… An iSax Laboratories creation. Thank you Martin Molin @ Wintergatan for inspiration! The original idea was to produce a MIDI controlled music machine that could play any …

SafetyLock: a Smart Lock Made With Raspberry Pi (Fingerprint and RFID)

“Have you ever wanted a more accessible way to secure your house? If so, this is the solution for you! I made SafetyLock, this is a lock that can be opened with your fingerprint, a RFID badge and even through …

Self-Playing Melodica

“Turn your melodica into a compressed-air melodica controlled by Max and Arduino. It tries to follow the melodic contour it listens to! Disclaimer: this project aims at building an inaccurate self-playing melodica. If you want to build an accurate one …

Send multiple sensors data to Firebase using ESP8266

“Send multiple sensors data to Firebase realtime database using ESP8266 and Arduino. In this tutorial, you will learn how to send multiple sensors data to Firebase realtime database using ESP8266 (ESP-01) module and Arduino UNO. What You Will Learn …

Simple Flip Flop Circuit

“In this Instructable I show you how to make a Flip Flop LED circuit. The special thing about this circuit is that it does not use an IC (Integrated Circuit). By using different resistors, capacitors and transistors, I succeeded in …

Smart Coin Feeder

“Retrive coins the old way pushing buttons or the future way through Alexa or any voice assistant. This is another “Thing” I made inspired in my previous project Cuckoo IR Alexa exploring the home automation with the combo ” Alexa and …

Three-Fingered Electric Gripper

“Are you a mechatronics fan and are looking for a simple Arduino project to do? Well, here is a simple yet very important mechanism used in many robots nowadays. Robots are designed to satisfy a certain need or to make …

TinyCalibrator - OSC Calibrator and High Voltage Fuse Resetter

“Because the 8-pin ATtinys only have a few GPIO pins available, they are usually operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is …

Wireless AC Current Detector

“While making my previous Instructable (easy infrared proximity sensor) I figured out a few things about using 2 transistors in a row to amplify a very weak signal. In this Instructable I will elaborate on this principle which is also …

$20 Synth Project

“This guide is for complete beginners in electronics & synth making. We’ll be building the ‘Helios One’, a total bastard of a synth a MIDI controlled synth made from a low cost Arduino micro-controller and the Mozzi audio library. Even …
