We will solder a blinking, customizable name tag. We will also discuss and explain the design and the theory of operation.

A discrete astable BJT multivibrator feeding into a johnson decade counter, which drives the LEDs directly.
The counter can serve up to 10 segments.
The LED matrix can partitioned partitioned arbitrarily column-wise: multiple columns can be grouped onto a single counter output.
each counter output has one series current limiting resistor
last (unused) counter output feeds back to reset
multivibrator speed can be adjusted with a pot
on/off switch?
