## Summary

Elliot Williams and Jenny List review Henrik Forstén’s synthetic aperture radar (SAR) system mounted on a drone, which uses an FPGA and GPS data to create high-resolution 3D models of the ground. They discuss Sylvain Munaut’s software-defined radio (SDR) built from Tiny Tapeout ASIC components, marking a milestone for the open-source silicon platform. The hosts also cover the open-source port of Google's Find My network to ESP32 and other microcontrollers, enabling DIY tracking devices, and explore various hardware hacks including zipper repair, ultrasonic sound recording, and bleach printing on fabric.
