## Summary

Hosts Elliot Williams and Dan Maloney review a week of hardware hacks, including NASA's laser communications system for the Artemis 2 mission and the ESA's percussive maintenance of the JUICE probe. They discuss commercial products like the Heatbit Bitcoin mining space heater and DIY projects such as a portable vacuum tube ham radio and a laser projector built from hard drive components. The episode also covers medical technology involving microbubbles and ultrasound to breach the blood-brain barrier for drug delivery.
