Using the Muppet 2 breadboard to charge a 16.2V supercapacitor bank from a 12V power supply. First the buck potentiometer is slowly raised (slowly to keep the current in check), then the boost potentiometer is turned.

    I'm sure that it's more the journey you're interested in, but it seems there's an interesting new chip – "4A, Standalone Li-ion Battery Charger IC
    With Photovoltaic Cell MPPT Function CN3791" which is available on ebay, delivered, on a board, for <£3…

    the coil whine…. aaaahhhhh!!!

    Julian what’s happened to your reviews channel. I enjoyed your reviews.

    Interesting, Julian. I wonder about the waveform at the supercapacitor end and the peak voltage that they might have been subjected too.

    Cool, love this series, I always learn just a bit more each time you put one out, and I still maintain that part of remaining young is learning something new every day. Recently at a family get to gather, my son's friends met me for the first time, most of them told him in confidence that he looked like MY father in stead of the other way around. Guess that's what I get for having a youthful appearance at age 67. Sort of pissed off my wife though they said she looked more like my mother….

    Hi, Julian, can you please do some efficiency tests?

    Why use the buck side when the boost side is all you need?

    enlighting as ever julian… can we expect ilett power grid services soon ?

    Does having phase correct PWM have an advantage over fast PWM?

    Great video, but what was the point of bucking the 12V source? Um, scratch the question, the point was to keep the source current down, right?

    Useful video

    These videos with the horrible noise make me vary happy that we've moved past CRTs.
