## Summary

Dave Jones of EEVblog discusses the significant challenges he faced during the Kickstarter launch of his new digital multimeter, including manufacturing defects, logistical bottlenecks, and component sourcing issues. He details specific failures such as intermittent contacts in the range switch due to injection molding tolerances and units stuck in US customs due to reshipper ownership discrepancies. The conversation also covers the broader industry context of passive component shortages, the historical shift from mask ROM to reprogrammable microcontrollers, and debugging methodologies like using square waves for control loop stability.
