I’ve talked about HD44780 displays before – they’ve been a mainstay of microcontroller projects for literal decades. In the modern hobbyist world, there’s an elephant in the room – the …read more Continue reading Displays We Love Hacking: SPI and I2C
While most people may think that a keyboard is just a board with keys, those who read Hackaday will no doubt know that there’s an infinite variety of beautiful designs …read more Continue reading Smart Modular Keyboard Sports an E-ink Display and a Haptic Feedback Knob
As far as input devices go, the potentiometer is pretty straightforward: turn it left, turn it right, and you’ve pretty much seen all there is to see. For many applications …read more Continue reading OLED Display Kicks Knob Up Several Accurate Notches
One day, [mitxela] got bored and decided to build his own HDMI monitor – the unconventional way. HDMI has a few high-speed differential pairs, but it also has an I2C …read more Continue reading Making Your Own Technically-HDMI OLED Monitor
Prolific maker [sjm4306] tells us the first iteration of his soldering fan was little more than some cardboard, electrical tape, and a hacked up USB cable. But as we all …read more Continue reading Custom Soldering Fume Fan Doesn’t Skimp on Features
All across the country, parents are wondering what to do about the upcoming Trick Or Treat season. Measures such as social distancing, contact free treats, or simply doing it at home are all being weighed as a balance of fun and safety. [BuildXYZ] has decided to lean into the challenges …read more
[Adam Welch] has built macro pads in the past out of pre-fab key matrices and handfuls of Cherry MX clones. But all the stickers and custom keycaps in the world wouldn’t make those macro pads as versatile as a stream deck — those visual shortcut panels with tiny touchscreens for …read more

We’ve all been there. You’re manning the battle station, deep in the sim-racing or some other n00b-pwning zone and suddenly some loudmouth blows out your eardrums over Discord. It’s insulting to have to stop what you’re doing to find the right Windows volume slider. So why do that? Build [T3knomanzer]’s …read more

Does your drill go as fast as the manufacturer says it will? Well, you’d need a tachometer to figure that out. They’re not that expensive to buy, but as [Elite Worm] shows, they’re not that expensive to make, either — about $10 total if you get your parts from the …read more

The ESP8266 has become practically the 555 chip of WiFi connected microcontrollers. Traditionally, you’d buy one on a little breakout board with some pins and a few connectors, and then wire up anything else you need. The ESP8266’s big brother, the ESP32, hasn’t quite taken over from the ESP8266, but it has a lot more power and many more options. [Andreas] has a new video that shows seven new ESP32 boards that have integral displays. These boards can simplify a lot of applications where you need both WiFi and a user interface.
Of the boards examined, six of them have …read more
