This category includes all projects of Nerdiy.de which require a maximum of two hours for the implementation or construction.
I am not sure whether ESPs can really be abused to set up a botnet. Either way, you shouldn’t neglect the issue of security, even with the small ESPEasy devices. […]
Read moreSo that my MagicMirror is only switched on when I actually use it, I have configured a small automation using NodeRed. The screen is only switched on if movement is […]
Read moreI also needed a suitable hose system to build my solder fume extraction system. After a little trial and error, I decided to use the standard exhaust air hoses. These […]
Read moreSo that I can switch off my 3D printer automatically after the printing process, I installed a Sonoff relay so that it can interrupt the power supply to the entire […]
Read moreThe VL53L0x or its sister / brother, the VL53L1X is a very precise and relatively inexpensive laser distance sensor. With this, distances can be measured almost at millimeter-accuracy. In one […]
Read moreThe BME280 is one of the sensors that I use in almost all of my projects. With this sensor one can not only measure the temperature. The air humidity and […]
Read moreESPEasy can read out a large number of different sensors and / or control actuators (see also ESPEasy – Sensors & Actuators). With the help of the “Rules” it is […]
Read moreEspecially if your own circuit has a display to show values, the next step is often to connect an interface option. You can connect buttons or switches. A relatively cool […]
Read moreThe PCA9685 is quite a practical IC. This is connected to the microcontroller (e.g. ESP8266) via I2C and can then control up to 16 individual PWM channels. You can control […]
Read moreWhat I really appreciate about Spotify is the good connectivity. You can play or control music or podcasts on another device with just a few clicks. Thanks to the free […]
Read moreMit NodeRed bzw. den passenden Nodes könnt Ihr sehr leicht Daten aus dem Internet abrufen und aufbereitet anzeigen lassen. Ein praktischer Anwendungsfall dafür ist zum Beispiel der Abruf von Tankstellenpreisen […]
Read moreThe 3D printed housing of the “pxlDigits” was initially not intended to be “just” a 7-segment display with WiFi. Originally I used it to build a kind of timer from […]
Read moreThere are some situations in which connecting an LDR to an ESP makes sense. In this way, the brightness in a room can be measured relatively easily and for little […]
Read moreI started with the documentation of the pxlBlcks (which I had been postponed for a too long time) in November 2020 after Hackaday.com had announced the “GoodBye 2020” challenge. (More […]
Read moreActually not one of the typical articles for Nerdiy.de, but recently I was looking for a tambourine that I could operate myself while playing the guitar. Long story short: Everything […]
Read moreWhen looking for a foot rattle to accompany guitar playing, I had the same problem as with the foot tambourine. So again: do it yourself. 🙂 Instructions for building your […]
Read moreThe pxlBlck_RingClock is very similar to the pxlBlck_SlotClock. It is also built using a 1 × 60 LED matrix and can display the time according to the same scheme as […]
Read moreThe pxlBlck_8x8 was one of the first members of the pxlBlck family. Thanks to the few parts and the prefabricated WS2812 8×8 LED matrix, it is set up fairly quickly […]
Read moreI started developing the pxlBlcks because I was looking for a way to stay informed about events in the SmartHome. There are now two options integrated into the pxlBlck plug-in. […]
Read moreWith the pxlBlck you can be informed about events in different ways. One of these possibilities is to be able to display previously set icons. Unfortunately, this option only works […]
Read moreThe adjustable dials differ from the type of LED matrix used. Unfortunately, this is the case because different LED-matrix sizes allow or do not allow different dials and screensavers. In […]
Read moreIf you not only want to stay informed about events with your pxlBlck and also use it to display the current time, then it might be you noticed that a […]
Read moreThanks to WiFi and thus (often) an internet connection, an ESP8266 or ESP32 programmed with ESPEasy also has the option to retrieve the actual time. In order for this to […]
Read moreFor a camping trip I was looking for a cheap and bright fairy light. This should be waterproof and bright enough to illuminate the tent properly. It would be perfect […]
Read moreDuring the construction of a chain of lights, I was faced with the problem of how to get this chain of lights waterproof. Ultimately, I built the electronic components, which […]
Read moreIn the past few weeks I’ve had the problem that my freezer door didn’t close properly. As a result, at least one night, the refrigerator door was not properly closed […]
Read moreThe PCA9685 is a PWM port expander. This makes it possible to connect up to 16 LEDs, servos or other components to your ESP8266 and supply them with a PWM […]
Read moreThe RaspberryPi can be equipped with a speaker in various ways. The easiest way is the connection via the 3.5mm jack plug. There is also the option of having the […]
Read moreIn the article RaspberryPi – Install “Shairport” Airplay-server on the RaspberryPi, I described how you can easily expand your RaspberryPi with the function of an AirPlay speaker. Thanks to another […]
Read moreAnyone who uses one (or more) Apple devices is certainly familiar with the AirPlay function. Thanks to this, media of all kinds can be streamed to other devices in the […]
