I know, I know. It's getting kind of boring, but I still like to watch the hummingbirds at the feeder. This is the first time where simultaneous (or nearly simultaneous) feeding was recorded by my Raspberry Pi camera. Pretty cool.

$Arduino, analogWrite, and DC voltages This morning I quickly put together a little RC filter to turn the PWM output of the Arduino into smoothly varying analog voltage to control the VCO in my G0UPL low power beacon transmitter. I think the filter is actually a bit too aggressive, it takes a significant fraction of a second to settle on the new value. Ill get a different cap in there later to speed that up a bit. (Apologies for the soft focus, Ill remember to use the macro next time).$
