Vintage PCB

I just picked up this vintage metronome at the thrift store and found this really cool looking PCB design when I went to change the battery. I've never seen anything like this, so I thought I would share! The soldering is pretty damn sloppy, but the connections are so psychedelic! Super cool

Hi !! Im happy to share my latest project. It's an ESP32-based board crafted for flexible projects, featuring an IMU, ADCs, XBee socket, RTC, Buzzer, Li-ion battery charger (1.5A) and monitor, general-purpose IOs, pushbuttons, RGB LEDs, SD card slot, Qwiic connectors, ambient temperature, humidity, pressure sensors, and USB programming capability! Almost completely SMT.

The PCB is a 4-layer design that I personally assembled <3
