Inside the box: Everything I did with an Arduino starter kit

Earlier this year I saw a Tech Ingredients episode where a laser gimbal automatically tracks drones and shoots them down. I was fascinated by their motion control mechanism, specially the usage of a PI Controller, a high-frequency clock Teensy microcontroller, and their integration with custom hardware and a machine vision powered tracker. Soon after I was researching the underlying electronics and how to experiment upon their concepts. The most obvious microcontroller to drive these would be a

Show HN: FlopperZiro – A DIY open-source Flipper Zero clone

An orribol copi of FlipperZero, uit worst inglish A Flipper Zero clone, but cheapest, DIY and simply Open Source, made with Arduino IDE ⚠️ Important Notice: This is just a fun project, it was started to pass the time, it is not at all professional and is not intended to be.

Show HN: Open-Source International Space Station Tracker ESP32/Arduino for $20

International Space Station Tracker SpaceStationTracker is an application that displays the current position of the International Space Station on a 2D world map. It runs on a ESP32-2432S028R ILI9341 device with a 2.8" screen, commonly known as the CYD "Cheap Yellow Display", which costs $20 or less. The code was written using Arduino IDE / ESP32 development environment in c++. I used this project to learn programming for ESP32/Arduino/CYD. It includes topics such as graphics using LVGL, wifi
