Open Hardware/Modding: Arduino Simulator and Raspberry Pi 5

CNX Software ☛ ArduinoSimulator is an open-source Arduino Simulator that runs in your web browser
Leonardo Russo’s ArduinoSimulator is an open-source Arduino Simulator written in JavaScript that runs code directly in your web browser and shows the serial output and digital/analog pins status for various Arduino boards namely Arduino UNO R3, MEGA1280, MEGA2560, and NANO V3. We previously covered the Wokwi simulator for ESP32. Arduino, and Raspberry Pi RP2040 that’s a great little tool for educators to emulate circuits and run code right in a web browser, and it even supports the ESP32-P4 wireless MCU although it’s yet to be released. While the simulators are written in JavaScript and open-source, the tool itself is not, and for instance, you can’t run a self-hosted instance of Wokwi or use it offline.

Hackaday ☛ Arduino, Virtually
While simulating an Arduino isn’t a new idea, a recent project by [LRusso] provides an open source JavaScript simulator that runs in your browser. You can try it out live or host it yourself if you prefer.

Ken Shirriff ☛ Inside the mechanical Bendix Air Data Computer, part 3: pressure transducers
Aircraft have determined airspeed from air pressure for over a century. A port in the side of the plane provides the static air pressure,2 the air pressure outside the aircraft. A pitot tube points forward and receives the "total" air pressure, a higher pressure due to the speed of the airplane forcing air into the tube. The airspeed can be determined from the ratio of these two pressures, while the altitude can be determined from the static pressure.
