No one with a beard should be putting little bobbles in their beards, though its at least an improvement over hippie beads. No, they should be building Christmas displays in their beards.
Now I have myself a couple 555 chips, some red and green LEDs and an idea. Thinking a barrett, with perfboard hot glued to one side, using the metal of the clasp to hold onto the underbeard and a coin cell battery.
Right, so I need to breadboard this. I would really like to alternate green and red blinking, and I think I see how that can happen, which its funny as the way I would bee doing it, without using a spare transistor, would be using the odd diode as a Diode more than the whole light emitting action. Seems legit.
Peter's stuff.
