Embedded Files
I have many hobbies and most of them require some technical and software skills. I am including examples of the projects that I have worked on, in my spare time.
Android Bluetooth scanning app
Android Bluetooth scanning app
I worked on a contract developing software for Bluetooth iBeacons. I had so many iBeacon devices positioned around my house, that it was difficult to remember where they were located.
I developed an Android Bluetooth-scanning app for BLE devices.
With this app, I could generate a list of all BLE devices nearby, and select one of the devices to track. The app created an audio chirp that varied in frequency, depending on the signal strength.
As I walked around the house, the audio frequency of the chirp would rise, as I got closer to the selected BLE device.

Language and Platforms: Android Java, developed with Android Studio.
Android "Internet Connection Alert" app
Android "Internet Connection Alert" app
I developed an Android app to periodically check the connection to the internet. Whenever the status changes, a pop-up notification is displayed with an audible alert. This app is published on the Google Play Store and supports devices running Android 4.3 - Latest version.
The app has several technical options and logs the status changes to a csv file in a public folder. It has been difficult to support this app, while maintaining compatibility for old Android versions and the limitations imposed by the latest Android OS.
When testing is started, a persistent Foreground Service is created, with an icon always displayed in the Notification area.

Language and Platforms: Android Java, developed with Android Studio.
Android "Tello Flight Control" app
Android "Tello Flight Control" app
I developed an Android app to control a DJI Tello drone, using the Tello SDK command set. UDP sockets are used to communicate with the drone over WIFI. This is a simple command-demonstrator app. It allows the user to manually type in drone commands. A link to the Java source code is provided for developers.

STM32F407 - Embedded C
STM32F407 - Embedded C
Using the Eclipse IDE, I designed a simple "casino" game, controlling the STM32 board's LEDs and using the board's audio circuits to play custom messages.
Language and Platforms: Embedded C, developed on the Eclipse IDE, with the STM32 Toolchain.
Python Fractal Graphics Renders
Python Fractal Graphics Renders
I got interested in Fractals, so I researched the Math and algorithms. I created a custom Python rendering engine, with parallel processing, for generating Mandelbrot fractal zooms. The images are oversampled, then downsampled with bicubic interpolation, to reduce pixel noise. The command-line Python app creates still sequences, and also generates an animated GIF, as it zooms into the destination coordinates.

I followed some VIDEO COPILOT tutorials and created demon face transformations. This demon transformation of my cousin, is one of my best.
