Not a whole lot of success today. I bought inductors, capacitors, and more parts bins (for glass in the workshop) from Halted, and spent much of the rest of the day poking at a circuit meant to produce a sine wave from a square wave. With the exception of learning I had the transistors in backwards all along(!) I didn't make a lot more success, just more square waves with a little bit of the corners rounded off. I did get some change to the circuit near the end: noticeable inductive ringing on the edge transitions, but by then (5:30p) I was tired of not making progress and called it a day. I instead watched Batman Begins then headed to the city for at-home dinner with Melinda.
Today: brunch w/ Melinda's labmates; stop at sfDisplay to buy a case for Melinda's apartment and another for mine, for coins; more circuit fiddling; glass this evening when Melinda gets home.
