Prototypes, Testers & USB Isolation Upgrades -

Last week, we conducted a Great Search for a clear shaft linear potentiometer. This week, the prototypes arrived—and they work great! We're also beginning work on the FruitJam Tester. We'll be showing the finalized silkscreen, the cover plate we designed, and the expected form factor of the tester itself. Additionally, we wrapped up a library for a QMC5883 breakout. This chip serves as a drop-in replacement for the now-discontinued HMC5883. It's frequently found in quadcopter builds, so we thought it would be a great candidate for a simple magnetometer breakout.
