Field notes
The landing page organizes its notes around six failure modes, from hot FETs and bad readings to EMC failures and solder joints. Individual entries pair named parts or boards with tightly framed comparisons: one note contrasts inductor construction using a nearby-trace reading, while another examines shunt-tap placement against a 0.5 mΩ shunt. Search, videos, history, logistics, glossary, and board links offer several routes through the material.
