Live Apollo 11 Transcript On eInk Display

There are few moments in history that have ever been recorded in more detail or analyzed as thoroughly as the Apollo 11 mission to the Moon. Getting three men to our nearest celestial neighbor and back in one piece took a lot of careful planning, and recording every moment of …read more

High-Tech Alms Collection With The ESP32

In an ideal world, shop space, tools, and components would be free. But until we get to that Star Trek utopia, hackerspaces will have to rely on donations from the community to help stay afloat. While asking for money, at least you can have some fun with it if you …read more

Hardware Notifications For ISS Flybys

Since Sputnik launched in the 1950s, it’s been possible to look outside at night and spot artificial satellites orbiting with the naked eye. While Sputnik isn’t up there anymore, a larger, more modern satellite is readily located: the International Space Station. In fact, NASA has a program which will alert …read more

Hacking This Smart Bulb Is Almost Too Easy

The regular Hackaday reader no longer needs to be reminded about how popular the ESP8266 is; they see the evidence of that several times a day. But what might not be quite so obvious is that it isn’t just us hacker types that are in love with the inexpensive IoT …read more

Building A Development Board For The STM32 G0 Series

When [Andy Brown] recently tripped over ST’s new G0 series of MCUs, he figured after some research that the best way to learn everything there’s to know about the STM32G0xx by making his own development board based around the STM32G081. The result is a Nucleo-style board, breaking out all pins …read more

A Wedding Gift Fit For A Hardware Hacker

If you read Hackaday on a regular basis, there are some names you will have seen more than once. People who continually produce fascinating and inventive projects that amaze and delight us, and who always keep us coming back for more. One such hacker is [Jeroen Domberg], perhaps better known …read more

ESP32 Gets Advance Windowed Apps Using This VGA GUI Library

We featured [Fabrizio Di Vittorio]’s FabGL library for the ESP32 back in April of this year. This library allows VGA output using a simple resistor based DAC (3 resistors for 8 colors; 6 resistors for 64 colors), and includes functions for PS/2 mouse and keyboard input, a graphics library, and …read more

Understanding Elliptic Curve Cryptography And Embedded Security

We all know the usual jokes about the ‘S’ in ‘IoT’ standing for ‘Security’. It’s hardly a secret that security in embedded, networked devices (‘IoT devices’) is all too often a last-minute task that gets left to whichever intern was unfortunate enough to walk first into the office that day. …read more

Blisteringly Fast Machine Learning On An Arduino Uno

Even though machine learning AKA ‘deep learning’ / ‘artificial intelligence’ has been around for several decades now, it’s only recently that computing power has become fast enough to do anything useful with the science.

However, to fully understand how a neural network (NN) works, [Dimitris Tassopoulos] has stripped the concept …read more
