## Summary

Hackaday editors Elliot Williams and Tom Nardi review a week of hacks, including the Positron V3 upside-down 3D printer, Caleb Olsen’s laser-guided dog poop detector, and DIY pulsar detection using an RTL-SDR. They also discuss Dyson’s battery management failures, a DIY STM32 sound card, and the vulnerability of GPS signals to jamming and spoofing.
