I had too many micro controllers and sensors and I wanted to have simple box where I can put them and easily find my modules again. This is the perfect use case for 3D printing: Of cause the modules and micro controllers come in different sizes so the design needed Read more…
Introduction Most Microcontrollers have a built in Serial USB functionality that can not be changed (e.g. ESP32, ESP8266, Arduino Nano etc). Some Microcontrollers however allow to (re-)progam the USB functionality (e.g. Raspberry Pico, ESP32-S2, seeeduino xiao etc) and TinyUSB is the project of choice for this. A Microcontroller can either Read more…
I am quite enthusiastic about the new Raspberry Pico. However I find the C SDK not very friendly and I prefer to have something as simple as the Arduino API. I did not want to wait for the official Arduino support – so I started my own project. The last Read more…

On Friday I was receiving my Raspberry PI Pico and I had the opportunity to play around with it. Actually most of the time I spent reading the Manuals… The conclusion: interesting – but a little bit too complicated to use – So I was quite happy to read that Read more…
I really wanted to have an interactive Jupyter environemnt in which I could play around with Arduino commands and when I discovered that Arduino provides a good starting point with their ArduinoCore-API I started to draft this prototype. I am using xeus-cling as a runtime environment to simulate an Arduino Read more…
Hardware I was receiving my ordered SD module but I was struggling a bit to connect it to my ESP32 via the SPI interface. I double checked the connections to make sure that I was using the right SPI pins, no change! I reformatted the SD drive again using FAT32. Read more…
For one of my current projects I had a closer look into the HTTP Protocol. Usually you might use a separate library for doing http calls from Arduino (e.g. with an ESP32) but if you are low on memory, you might get away without this by just using the WiFiClient: Read more…
When I was in University 40 years ago, I was a big fan of C++. However I never had the need to do any projects in this language so far. I did plenty of work in ABAP, Java and later on enjoyed the relaxed approach on the usage of semicolons Read more…
