Why I heart valves


OK. I know this is an old video, but this guy is everything that is cool about analog circuits. He has great hair, a great accent, and he waxes poetic about electrons passing through a vaccum.

Farewell my Subaru


So I heard about this book on a local blog and found out that the author, besides sharing my first name, had a Subaru the same year as mine and lives just a few hours away. I wanted to see what a tech-oriented person does with peak-oil.

Oscilloscope

As you can see, it works. I thought this picture showed the new vs. the old of electronics, and how they can still play together fine. The mac is sending out a 1k sine wave to the scope.

The hat in the middle is to remember Scott Ramsey, who passed away the week before the concert. He was a key arranger for the band and a fine Flugel player.
