I made Simon_pocket - a pocket version of the classic simon says game. I designed a PCB, wrote bare metal code for the microcontroller and designed an enclosure. I am very happy with the PCB and code, but it think that I need to improve my 3D modeling skills and make better models in the future. I am really happy that i was able to learn so much about the programming of STM32 microcontrollers even if it took a long time. In the future i hope to make projects with more interesting electronic circuits.

I just prepared a few 3D printed housings and PCBs. My 3D printed parts have bridges that don’t turn out very well, so i need to use some tools to grind them down. I think that my filament is wet, so I’m experiencing this problem.

I just updated the Simon_pocket housing 3D model. It now has a tighter locking mechanism and a thinner loop for connecting to key rings. I am also finishing up my README document. I have created all of the diagrams and pictures i need. I attached a picture of the old and the new versions of the housing.

I just soldered 2 PCBs by hand and 5 PCBs using a solder paste stencil. I was very suprised that the solder paste and stencil were easy to use. Using the stencil, i soldered 5 PCBs in about the same time it would have taken me to solder 1 PCB by hand. The stencil also improved the solder quality. It looks way better than doing it by hand. Even though i used a cheap solder paste, I still got great results.

Today I finished 2 diagrams for the code logic and took a screenshot of my Fusion workspace to put in my README file. I also took 2 images of the real soldered PCBs. The README is starting to look really good

I started 2 diagrams for my project’s code/game logic. I will put them in my README file on my github. At first i had a hard time figuring out how to display the code logic, but after talking to Gemini i decided to do 2 different diagrams: one for system state transitions and the other for how the code is structured. I attached images of both unfinnished diagrams.

I created a block diagram to explain the gameplay of my project. I did it in diagrams.net. I really like how it looks and it makes my README.md way better. I also fixed file formats of some images, because github doesnt suppord PDFs in the README and i had a hard time exporting .svg files. I later realised that i can put a black rectangle behind my PCB svg and now the constrast is really good and i can see everything clearly.
