Is Father's Day over yet?

My wife told me tonight that most men, when polled, say that their ideal Father's Day is a 12 pack of beer and to be, "Left the hell alone" for a day.

I apparently did this wrong.  :)

We constructed a giant Estes model rocket.  Our rocket was "The Dude" (like this one above (not us)) a 7 foot long, inflatable chrome mylar rocket.  My wife had found it at Walmart about 3 years ago.  It had been gathering dust in the basement since then, except when my younger son periodically found it and asked, "When are we going to launch this?".

Apparently today was the day.  We put it together and went out and launched it three times.

Very fun.

After that, after we cooled down, we came home and then spent the afternoon building everyone a home made LED "flashlight" out of some plastic snus cans, momentary contact switches, LED's, 9 volt batteries and resistors.  So, the boys got a chance to learn some basic soldering, constructing a basic series circuit and we had a very minor conversation about Ohm's law.

This page is pretty good is you want to make this circuit:

We made:

  • 2x High brightness white LED's
  • 2x Yellow LED's
  • 2x Ultra high brightness LED's
  • 1 with a red LED and a pulsing (effect from the blinking LED in series) high brightness white LED

So, anyway, a fun day, but I'm exhausted.  I should have taken a vacation day tomorrow.  :)
