What is a Spacecraft On-Board Computer (OBC)

A Spacecraft On-board Computer (OBC) is essentially a fully redundant radiation hardened, self-contained flight computer for satellite application.

A dual-String Single board Computer with 28V-70V power supply and interfacing provide all the power required for most satellite application
The heart of the computer is the radiation hardened version of a processor that can withstand the most stringent radiation environment.
Processing capability is usually requiring a radiation hardened SRAM and EEPROM providing the needed processing capabilities and memory of most spacecraft control application.

How to Play a Sound After a Terminal Command Completes

Sometimes, while working on the terminal, especially during long-running processes, it’s useful to have an audible notification when the task is finished. In this guide, we’ll show you how to make your terminal play a sound after any command completes, ensuring you're alerted without constantly checking the terminal. Why Do This? This trick can save time and improve workflow, especially when: You’re running lengthy build processes or installations. You’re waiting for large file transfers. You're programming embedded systems and need confirmation when flashing is done. Let’s dive into how to do this on a Linux system. Step-by-Step Guide to Playing a Sound After a Command 1. Using paplay or aplay to Play Sounds On most Linux distributions, you can use paplay or aplay to play sound files directly from the terminal. Here's how you can append a sound notification after a command. Basic Command Structure : PC:~$ your_command && paplay /path/to/soundfile.oga Or, if...

Building a Robot Actuator with ESP32 and a 5010 BLDC Motor

Introduction Modern robotics demands actuators that aren’t just strong, but also smart — capable of precise control, smooth motion, and safe human interaction. Traditional servos are great for small robots, but they can be stiff, noisy, and limited in range or torque. This project demonstrates a custom robot actuator built around a 5010 360 KV brushless DC (BLDC) motor , controlled by an ESP32 running the SimpleFOC library. The goal is to create a compliant joint — one that can be moved by hand, but automatically returns to its home position with adaptive stiffness. 🧠 What Makes This Actuator Special Unlike a typical servo, this actuator behaves intelligently : You can turn it by hand — it feels soft and back-drivable. When you release it, the motor returns to its initial position smoothly. If you twist it harder (e.g., due to gear reduction), it becomes stiffer , resisting displacement more strongly. It’s powered by 12 V and controlled by a simple ESP32 boar...

Heating with Electric Radiators

You want to heat your small garage using a couple of electric radiators. The power and voltage requirements for each radiator are 1200 W, 240 V. But you are not sure how to wire the radiators to the power supplied to the garage. Should you use the wiring diagram on the left or the one on the right? Does it make any difference?
