Here’s how to build a simple robotic arm with a gripper using popsicle sticks, an Arduino, and a few servos. Supplies: Feel free to use similar materials or whatever you already have. (e.g. cardboard instead of popsicle sticks) Materials: 14 Popsicle Sticks 4 Micro Servos (with their horns and screws) 4 Rotary Potentiometers 1 Half […]
The problem Imagine this: You wake up one morning and the weather is real good. You want to go to the beach.Because you don’t live too close to the beach, you take your car. To pay for the parkingat the beach, you use your phone. This means that you go to the beach carrying (at
Relive the fun of early computer game music with an authentic 8-bit chiptune synthesizer, which you can control over MIDI from the comfort of any modern DAW software. This simple circuit uses an Arduino to drive an AY-3-8910 programmable sound generator chip (or one of its many clones) to recreate that 1980’s sound. Unlike the many designs
Today I will share how to make a WIFI JOYSTICK from an ESP8266 and 4 ways industrial joystick. It can be integrated into the factory’s automation system or be used for smart home control. The mentioned control systems are PLCs and the specific case that I am applying is SIEMENS PLC S7-300….. Let’s start and
Which uses more water – a bath or a shower? I was recently thinking about this question, and I realized that I don’t actually know how much water is used when I shower. I know when I’m in the shower sometimes my mind wanders, thinking about a cool new projects idea or trying to decide

What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic
This instructables show how to use a square color display and Arduino dev board build a watch core. This will cover the topics of dev board selection, display selection, extra modules selection, UI design, performance tuning and power saving. Note: I have prototyped some Arduino Watches few years ago. But the hardware sizes at that
I have in my hand a distance laser sensor with high precision and speed. It is used in industrial environments for object positioning or detection applications. According to technical documents, I found it can communicate with other devices via RS485. I spent the weekend to learn it and find ways to communicate with cheap CPU

Origins: This is a game I developed over a couple of years 2018-2019 It was originally called “Stupid Flip” and came out of my interest in creating simple and fun interactive games that could also be used for teaching coding. This is about the simplest game imaginable and involves flipping an arm from one player
Alaska is on the edge of advancing climate change. Its unique position of having a fairly untouched landscape populated with a variety of coal mine canaries enables a lot of research possibilities. Our friend Monty is an Archaeologist who helps with camps for kids in Native Villages scattered around the state–Culturalalaska.com. He has been building
