Project History
GUI for Instagram Automation
https://github.com/oscilo/Nitrogram- a desktop GUI (with requirements of a specific design) for Instagram automation;
- a C++ API for Instagram requests.
2) I built a GUI (using Qt Widgets and QSS styling) that looks exactly as the provided design. Also, I implemented the required API to perform native Instagram requests.
3) The project is not completed yet. My client decided to freeze it for a while.
GUI for Chemical Analysis Instruments
https://github.com/oscilo/PotentiostatMain features are:
1. Running pre-built experiments (+ easy creating of new experiments)
2. Dynamic experiment builder (drag and drop nodes of the experiment)
3. Multiple graphs plotter
4. Firmware updating
