## Summary

Editors Mike Szczys and Elliot Williams discuss the Hackaday Prize winners, including Flow IO's pneumatic robotics platform and Norbert Heinz's plastic granule extruder. They review several hacks: Yasak Federinsky's dual-trackball mouse, a study on green programming languages, a solar-powered BEAM robot, and running DOOM on a Bluetooth dongle using an nRF52840 chip. The episode also covers privacy issues in Android OS, controlling lab equipment via SCPI, and a massive custom e-bike battery build.
