This episode discusses ongoing PCB failures, oscilloscope overdrive recovery, a BT-enabled headphone that would just keep connecting, some local events (GLOW, Awesome Space repair day, and the HCC Retro quarterly meeting). Finally, an experiment gone out of control resulted in a small PCB for generating colour effects for 4 connected VGA monitors. Ruby is used as "effect description language".
