finished up schematic! Still need to do a double check. Main things worked on: • Calculating gain for amplifier • Adding voltage regulator • Adding resistances for LEDs

haha, i forgot how simple a PCB biz card is! The schematic is just 5 parts!

This took a lot longer than I thought it would take: designed a custom antenna for the #frc x #onboard trinket. It's specifically tuned for biz card. Some additional resources for y'all curious in designing your own: • NFC Antenna Design Webinar • Key equation: Ideal Inductance = 1/( (2pi freq)^2 chip_capacitance)) • Impedance Calculator • Antenna footprint generator

Ahhhh! Robotics had me crazy today so I couldn’t sit down and CAD a case. Regardless, I made this cool pivoting gearbox that has a 400:1 gear ratio. And it was a clear sky day too!
