Hearing loss is a common problem for many – especially those who may have attended too many loud concerts in their youth. [mircemk] had recently been for a hearing test, and noticed that the procedure was actually quite straightforward. Armed with this knowledge, he decided to build his own test system and document it for others to […]

In the world of hardware hacking, you sometimes spend a ridiculous amount of time debugging a problem, only to find a simple solution that was right in front of you the whole time. [Zack Freedman] got a good dose of this while building the Optigon V2, a modified Epson Moverio wearable display he uses as a
CUTTING A WEARABLE DISPLAY IN HALF IS HARDER AND SIMPLER THAN IT SEEMS Continue Reading
In this tutorial I am going to show you guys how to make an Arduino or NodeMCU based Weather Station using DHT11 or DHT22 temperature and humidity sensor and display it using an OLED Display. Video In this tutorial I am going to show you guys how to make an Arduino or NodeMCU based Weather

Older hackers will remember that a crystal set radio receiver was often one of the first projects attempted. Times have changed, but there’s still something magical about gathering invisible signals from the air and listening to the radio on a homemade receiver. [mircemk] has brought the idea right up to date by building an FM radio with

In this tutorial I will show you how to create animation on small OLED display connected to Arduino Nano. Step 1: Supplies We need following two components for this project Arduino Nano SSD1306 SPI 128×32 display You can also use SSD1306SPI 128×32 display but it will need code adjustments when declaring the display. Step 2:

There’s something about Reverse Polish Notation (RPN) and the calculators that use it. It calls to mind a time when a calculator was a serious tool, and not just a throwaway toy. Created in the legacy of such calculators by HP and Texas Instruments, [Simon Boak] shows off his SB116, sporting an Arduino Nano under the

Every now and then you might be interested to input text to your arduino project. You can do it using Serial input but this would require Arduino to be always connected to a computer. In this tutorial I would show you how to implement text input using the small OLED display and 5 key keyboard
A new project will soon be launching via the Crowd Supply website in the form of the fully programmable, open source, ESP32 macropad, aptly named DeepDeck. The wireless programmable macropad features 16 mechanical buttons in a 4×4 grid together with two RGB rotary encoders, hot swappable keys and more. Connecting to a wide variety of different platforms using Bluetooth, DeepDeck supports Windows, MacOS,

I have multiple bioactive tropical vivariums for my crested geckos, and I always need to spray them morning and night, as well as when the humidity is too low (which happens multiple times per day), and I have to turn on and off the lights and monitor the temperature. I’ve made some small projects with

The tiny 0.96 inches OLED display is the most popular among the Arduino fraternity for displaying data like room temperature, humidity, and text messages. Have you ever thought of displaying your own photo on the display! Yes, it’s possible. In this Arduino-based project, we learn to display any photo on this small display. The above
