Simple Keras NN for for MNiST. Played with Streamlit + Heroku and developed an app template on GitHub. Also, wrote an article about it. Try it yourself! https://digitsonline.herokuapp.com 
48x48px greyscale face -> Tensorflow DNN -> Emotion Classified. First worked on the Tensorflow model. Second, tried to execute some of the DNN convolutions on the FPGA - and succeeded! Play with my model using you own photo here. 
First big programming project. Designed, build and assembled PCB and programmed the AVR uC in C. Had lots of fun, and it works till now!
Built a prototype of a power plant for a middle-school competition. Our project actually won!
