## Summary

Elliot Williams and Jenny List discuss a Nissan Leaf security hack by PC Automotive, where researchers exploited the Bluetooth infotainment system to gain remote control of vehicle functions by bypassing the gateway ECU. They also cover DIY projects including Les's homebrew Pockel cell using grown crystals and a diamond wire saw, and MIT Lincoln Lab's technique for 3D printing fused silicate glass. The episode highlights mechanical 7-segment displays, a comparison of CNC vs 3D printing workflows, and the history of satellite phones.
