Overview The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. You can find further information in the original Readme of the STK Project Like many other sound libraries it originates from an University (Princeton) Read more…
I was looking for an easy to implement solution to control my RC Airplane (that is using a ESP32 micro controller) with the help of a Mobile Application. I decided to use QGroundControl which is based on Mavlink. My project provides the following features: It is available as Arduino Library Read more…
I proudly announce that my Spektrum Satellite Arduino Library has been released with the version 1.0.0 on Github: It features: A Complete Implementation of Official Specification Support for binding using different BindModes Support for receiving and sending of data Input and output are handled via Streams. So you can use Read more…
After my bad experiance with this topc I decided to give it another try. I assumed that my issue from last time was that the receiver did not get enough power (after all it was a bad idea to power the satellite from a GPIO pin directly) so I decided Read more…
I was building a small Remote Control for my RC toys with the help of a ESP32. This Microcontroller is the perfect choice because – it supports enough analog input pins (we need at least 4) – We can use Bluetooth or UDP as Communication Protocol out of the box Read more…
The ESP32 provides a Bluetooth A2DP API that receives sound data e.g. from your Mobile Phone and makes it available via a callback method. The output is a PCM data stream decoded from SBC format. The documentation can be found here. I2S is an electrical serial bus interface standard used Read more…
I bought myself a 3D printer and I thought it would be cool to program the models in Jupyter. I am currently doing quite some development in Scala so a JVM based solution running in Jupyter would be my preferred option. Most of the people use some GUI driven CAD Read more…
The initial concept of Smart EDGAR was to provide the tools to download the data from the EDGAR website and – store the information as local files – store the information in a SQL database – provide reporting functionality from this data We have extended the functionality a little bit Read more…
Because Investor has been implemented in Java and is available as jars from a Maven repository we can easily use the framework in all languages which are based on the the JVM. Here is a quick demo using Jupyter Lab (using Beakerx) with: – Scala – Java – Groovy – Read more…
