In the days before every piece of equipment was an internet-connected box with an OLED display, engineers had to be a bit more creative with how they chose to communicate information to the user. Indicator lights, analog meters, and even Nixie tubes are just a few of the many methods employed, and are still in […]

A common hacker upgrade to an espresso machine is to improve stability and performance with a better temperature controller, but [Schematix]’s Smart Coffee project doesn’t stop there. It entirely replaces the machine’s controller and provides an optional array of improvements for a variety of single-boiler machines (which is most of them). Smart Coffee isn’t free, it
SMART COFFEE REPLACES ESPRESSO MACHINE CONTROLLER WITH ARDUINO, SENSORS Continue Reading
You’ve got to love the aesthetics of dystopian cyberpunk video games, where all the technology looks like it’s cobbled together from cast-off bits of the old world’s remains. Kudos go to those who attempt to recreate these virtual props and bring them into the real world, but our highest praise goes to those who not

The magnetic compass has been a crucial navigational tool for around a thousand years or so, perhaps longer. While classical versions still work perfectly well, you can now get digital magnetometers that work in much the same way. [mircemk] decided to whip up a digital compass to demonstrate the value of these parts. The build uses

There are lots of Instructables on how to use SSD1306-based 128×64 OLED displays. Many of these write-ups are very informative but just about all of them look like an unfinished science project. (In fairness, most are directed at getting up and running with the display, not creating a finished product). Here’s a quick and easy way to

[Görg Pflug] wrote in with his really nice graphics library. It’s got multiple layers, two text consoles, greyscale, internal halftoning, and sprites. It can pull off a number of classic graphics tricks and demos. Oh yeah, and did we mention it runs on a freaking ATtiny85 and an I2C OLED screen?! This is an amazing piece of work

We have built quite a number of weather stations in several past tutorials, with each one differing from the other by the use of a different sensor, different display, etc. Today, we are going to build another weather monitoring station using the BME280 Temp and humidity sensor from Adafruit and an OLED display. The BME280 is an integrated

Sony Corporation today announced the upcoming release of the ECX339A OLED Microdisplay featuring UXGA(1600 x 1200 resolution), the highest in class for a 0.5-type. This product achieves the world’s smallest pixel pitch of 6.3μm by leveraging Sony’s OLED display technology and miniaturization technology, enabling a resolution 1.6x higher than the previous model1. By employing a new drive circuit design that operates on half

Weather stations are interesting projects for beginners and very useful for expert makers. They are usually quite simple to build but also provide fairly accurate and useful weather data. We have built a couple of them in different tutorials on this website, with the difference usually being, the combinations and sometimes the accuracy of the sensors used.
ARDUINO AND BMP280 BASED WEATHER STATION Continue Reading
Just like Arduino, ESP32 has been one of the boards that have found love among hackers and makers around the world. Unlike general Arduino boards, ESP32 offers much more at a fraction of the cost and most importantly are usually compatible with Arduino based code. Recently we have seen the rising of ESP32 in the areas of Artificial Intelligence
