I'm focused on Flipper Zero tutorials (playlists: NOOB - beginner/intro information, GEEK - understand what is happening, CODE - dive into the code, DEMO - demonstrations, MAKE - electronics and 3d-printing.) If you are looking for tutorials for Flipper Zero - please let me know your ideas!
I also have videos for other hobbies... Lock picking, IoT devices, Hackathon projects, Fireworks, Haunted House, Java, etc.
