Can you do a video regarding using super capacitors on RC projects for momentary high voltages? 😉

An interesting idea, I would like to get some feedback on that and see what others think.  

Thaks for suggesting it!

I would find the background on super capacitors interesting.  I think there are other places where they might be useful.

I'm at the stage where I know what the basic electronic components do, I can follow and construct some of the more simple circuit diagrams, but I don't feel I can readily actually design a circuit for myself.   

For example I sort of get some things like the use of a diode to prevent back emf from a motor when the power is switched off, but let me think, do I put that on the positive or negative side and what diode specifications should I be looking for.  No it does not come natural to me as yet.  Often one does see a capacitor in a circut to smooth the electric supply, but whats the thought process in deciding on its capacity.   Sometimes in your presentations you indicate something like the an 'xxx of xxx capacity should suffice' but don't go on the explain the parameters within which you are making the call.

So what I am saying is 'Yes' an explanation and examples on the use of Super Capacitors would be of much interest, but so would the design consideration in the use of other components in the circuits you present.    

And a final thought.  As a design exercise, and one that could prove of much interest in the DB1 design, is to design a battery monitor circuit so that the LIPO batteries do not get discharged to their critical state and the SBC's they drive and indeed the DB1 itself can be shut down smoothly before that point is reached.  There are circuit designs out there and also some readily purchased components to help achieve this, but I would really appreciate a walk through of a bespoke DB1 circuit to achieve this.

I'll accept this, although it may be a while before I can get my hands on all of the components.
