Use The Protection Circuit
Dave Jones of EEV Blog and Chris Gammell of Contextual Electronics discuss the technical and logistical challenges of hardware development. They detail a Gerber file compatibility issue with JLC PCB when using Altium's plane layers, the high cost of prototyping with custom components like transformers and connectors, and the critical safety implications of using unprotected 18650 lithium cells. The conversation also touches on the cancellation of the Open Source Hardware Summit in China, the rise of USB 4, and the precision required for home-milled PCBs.
