FEEL THE FORCE WITH A POCKET MAGNETOMETER

With the rise of affordable 3D printers, we just don’t see the projects in Tic Tac boxes that we used to. That’s kind of a shame. Not only are you upcycling existing plastic when you use one, they’re decently sized component vessels for pocket builds such as [rgco]’s portable magnetometer, especially if you can get the 100-count box. Best of all, they’re see-through! Sure, you could get a magnetometer app f ...

Getting Started With the ESP8266 ESP-01

The ESP8266 ESP-01 is a Wi-Fi module that allows microcontrollers access to a Wi-Fi network. This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino, for example, because the ESP-01 acts as a small computer. Depending on the version of the ESP8266, ...

Sending Data From Arduino to Python Via USB

For several projects you might want to acquire some data from an Arduino board. There are several options and the one that I chose here uses the USB connection. I will explain how to store your data in a text file in order to plot it. I will use Python 3, the Arduino IDE and an Arduino UNO. (I'm working on Linux but I think it should be the same procedure under macOS and Windows.) Step 1: The Arduino Code T ...

NEW PART DAY: LED DRIVER IS FPGA DEV BOARD IN DISGUISE

Our new part of the day is the ColorLight 5A-75B, a board that’s meant to drive eight of those ubiquitous high-density color LED panels over gigabit Ethernet. If you were building a commercial LED wall, you’d screw a bunch of the LED panels together, daisy-chain a bunch of these boards to drive them, supply power, and you’d be done. Because of that high-volume application, these boards are inexpensive, arou ...

Read a Potentiometer With Arduino’s Analog Input

https://youtu.be/-EDYMQ9lczA Let's learn how to read a potentiometer, a type of rotating variable resistor, using Arduino's analog input! We'll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED. So far you've learned to control LEDs with Arduino's output, and you learned to detect a pushbutton's state (on or off) with digital input. In this le ...

Arduino for Nerf: Ballistic Chronograph

Arduino is an amazing tool for Makers, and as I got back into Nerf and started modding, I began to wonder what I could do with Arduindo to help determine the effect of modifications. Take a look at any older Nerf video and you will find a kid firing darts on their lawn over a tape measure. Take a look at any recent Nerf video, and you will see them shooting darts through an expensive ballistic chronograph. ...

Inkplate 6 Wi-Fi-enabled e-paper display 3D printed case

The development team at e-Radionica responsible for the awesome Inkplate 6 Wi-Fi-enabled e-paper display, have unveiled a new 3D printed case designed to provide a little extra protection and finish to the screen. The design files are not available for download quite yet, as the team wanted to make a few more tweaks before they are released, however as you can see from the image above the addition of an enc ...

A RETRO TOUCH PAD YOU CAN USE ON MODERN COMPUTERS

As [Jan Derogee] explains in the faux-retro video after the break, drawing on classic 8-bit computers was something of a pain. The rudimentary light pens and joysticks of the 1980s allowed for free-form input, but were clumsy and awkward to use. Which is why he set out to create an ideal drawing device for the C64 using modern electronics. For the sake of completion, he also gave it a USB HID mode so it wou ...

DIY – Automated Garden Irrigation – (Arduino / IOT)

This project will show you how to build an irrigation controller for a home garden. Capable of measuring soil moisture readings and activating irrigation from a garden tap if the soil becomes too dry. The controller also includes a temperature and humidity sensor. The controller will not activate the garden tap if the temperature is too low. Sensor readings and statistics about water usage / run times are r ...
