I had fun making this video. It's a Perl script that goes through a slideshow of Firefox screenshots rendering fictional end credits in pigpen symbols. I had a RasPi 3 play the slideshow via composite video and recorded it on VHS. The tape was then played back on an LCD TV and recorded with a camera. All background noise in the soundtrack is artificial and was created with TB ReelBus v4, Reaper, Audacity, and a little Perl script.

I've been listening to 70cm a lot lately, and had a scrap Yagi with no handle. But this "Universal Hacksaw 4.95€" works really well. I've since removed the blade and cut the curvy part of the blade off (with another saw).

Off-topic on #WorldAutismAwarenessDay - these #AutismTMI campaign videos are quite powerful (also, potentially distressing) - "This is what some autistic people face every day"

They're trying to avoid getting too technical here, but pretty interesting nevertheless.

Using redsea for RDS demodulation? You may get a better SNR by reducing the gain setting (-g) in rtl_fm. I got around 6 dB more by changing from -g 40 to -g 20 (possibly due to clipping as rtl_fm has no AGC?)

Funny fake tweeters in these speakers I found at a thrift shop (used to belong to a Philips MC147 mini-stereo system).
