➀ A DIY presence sensor kit using a millimeter wave sensor for motion tracking and heart rate monitoring. ➁ The sensor can detect up to three people and includes an environmental sensor. ➂ The project uses an ESP32 for processing and a 3D-printed case for assembly.

➀ Russell Eveleigh's Zero Pairs project uses a Raspberry Pi to visually explain negative numbers through a display of rotating balls. ➁ The project includes a web-based interface for inputting equations and adjusting settings. ➂ The project is open source, allowing educators and enthusiasts to explore and modify the code.

❶ A YouTuber, Hyperspace Pirate, demonstrated how to create liquid nitrogen (LN2) using components from refrigerators and air conditioning units. ❷ The homemade cryocooler produced 130cc of LN2 per hour, costing around $1.29 per liter, compared to $5 per liter if bought commercially. ❸ The project was mainly for fun and experimentation, using LN2 to freeze and shatter objects, and to demonstrate superconducting properties with YBCO.
