A portable speaker offering a ton of functions. 6 speaker drivers, wooden enclosure, WiFi LED equalizer, custom light patterns & much more...

Nothing can be compared when you can put your hard work to display on a 4” TFT display- From one end to the other end it's 480*360 pixel to play with.

This USB powered thermometer based on an Arduino Nano shows the temperature using a vintage Russian "nixie" style IN-9 bargraph tube.

Here we present a specific application with a weather station built around the ESP32, which makes all data directly available online.

Da ich in einem Fachwerkhaus ein Badzimmer sanieren möchte und sich dort aber die Geister zum Thema "Innendämmung" scheiden habe ich lange überlegt, wie ich sicherstellen kann, das die Fachwerkbalken nicht feucht werden und verschimmeln.Jeder hat zum Thema Innendämmung eine andere Meinung. Lange habe ich meine Dämmvariante hin und her berechnet.

The cold season stresses every car battery. This project helps to prevent deep discharges and record the voltage over a longer timespan.

VGA & audio interface for Raspberry Pi Zéro & 2,3,B+

This project includes a softstart circuit for powering up an audio-amplifier and some peripherie.

This is a remake of the Simple Nixieclock (140013-1). After this project was published we got a lot of questions from our readers about changing the time zone, which was fixed to GMT+1 in the original design but could be altered in the source code of the PIC microcontroller.

Another GPS Alarm Clock? You've got to be kidding! Read on to see how a new, easy to use touchscreen library manages the clock.
