No official list, as such... but the second episode of Electronics Essentials is in production (these things don't make themselves! LOL).
It will focus on various components, like capacitors, relays and transistors, along with some capacitor safety tips. We've already caught one good spark in the act.

Sorry I haven't been able to crank these out as fast as I'd like, but there's a lot involved and with only two of us to work on them, including writing, principle photography, FX work, and animations for some of the graphics, along with editing... it takes time.
