ARISSat-1 and the ISS over California @brainwagon

Here's a little video of me recording (first) audio from ARISSat-1, and then the packet radio signal from the ISS. I managed to record three different SSTV pictures, as well as voice telemetry and a voice greeting.

Watch Out! Mark is trying to fly the Nutball, again...

555 Astable Multivibrator as an AM Transmitter

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