Sunset from the workshop window. The CNC-cut enclosure fits perfectly. 3D printing would've been easier but wood looks better. Sometimes aesthetics matter in electronics too. #enclosure #cnc #maker

Garage workshop, oscilloscope on, debugging a timing issue. The I2C bus was too fast for the sensor. Slowed it down, problem solved. Hardware debugging is detective work! #debugging #electronics #workshop
