There is no other reason why I restrict this list to YouTube channels other than that is where I'm most likely to discover interesting videos. It's just where most online videos are. The channels in this list are in no particular order. Some pretty well-known and famous, some not that big, but all very interesting to watch to me.
- World Science Festival - Science panel talks - I've written about it here already.
- DIY Perks - Interesting electronics-related DIY projects, partly very elaborate. Nice voice.
- Technology Connections - In-depth explorations and explanations of technical, electrical and electronics topics. Retro tech, home appliances, traffic lights, video technology, ...
- TrackZero - Computer/digital electronics projects vlog. Homebrew computer hardware, vintage computer hardware.
- Tipharot - Short videos on lucid dreaming
- colinfurze - Weirdly over-the-top and professional-looking DIY builds
- Pursuit of Wonder - Philosophical and thought-provoking stories nicely told
- Absolute Unit (at this point still also known as "DWK's new channel") - Peeves and other personal shortcomings portrayed in a fun way
