K-9's first convention taught me a few lessons. The convention was in August and the AC in the building stopped working. The glue I used to keep K-9's head attached to his body weakened to the point where his head just fell off. I jammed a pocket knife into the two ends to keep it from happening again.

K-9's ears stopped functioning, hence the fez. My 5v step down transformer board blew due to the heat.

I decided that I didn't like K-9's eyes, body color, or keypad lighting sequencer. I built a flux capacitor circuit to "randomize" the blinking but it just wasn't good enough. Right after I tore K-9 down expecting to have until February the next year to have him fully upgraded he was invited to a local expo in November as a "guest".
