Raspberry Pi TV HAT
Hank P. bought the TV hat from PiHut. Neat. Link here and setup instructions here
Transmit audio over FM
For the ham radio enthusiasts, great piece of software called rpitx that can turn pi into a FM transmitter. Link to software here.
There is a specific use case in the new version - replay captured audio. Useful for automating doorbells etc that use RF.
Composite video with raspberry pi
Before this week, I was not aware that 3.5mm connector in the raspberry pi is capable of outputing video in addition to audio.
In order to do so, use need a special 4-pole 3.5 mm connector. Not all connectors are the same.
