## Summary

Dave Jones and Chris Gammell celebrate The Amp Hour's 360th episode with a live-streamed Q&A, discussing Dave's upcoming production of 50 early-release multimeters and his decision to stock a premium Japanese pocket multimeter. They brainstorm the design of a portable 'micro supply' power supply, debating the use of the LTC3780 buck-boost controller, battery options like 18650 cells, and noise reduction techniques. The conversation also covers industry news, including John Deere's acquisition of Blue River Technology, the failure of Juicero, and the technical challenges of designing portable lab equipment.
