It's a fairly common circuit, if you examine night lights ..... It's not as wasteful as it looks; because when the LEDs are shorted out, the series capacitor will ensure the impedance presented to the supply is mostly capacitive. In a pure reactive load, the energy is all imaginary; which means it is not being consumed, but stored up as potential energy during one part of the cycle and released during a different part. With a hand-cranked generator, you would feel stiffness during the storage and it would get easier to turn during the release.
Of course, you are not wrong. still, why not make it "right" in the first place, instead of copying a pretty shitty circuit over and over again? In regards of the power consumption: Thats not wrong either, but reactive power is still loading the infrastructure, as there is a current flowing, even though its not being consumed or billed (at least consumers aren't.). This increases the load on the power grid which is already way too high where I live, as it was ignored to upgrade it for over 20 years now. For DIY fun projects I don't care either, but in a commercial product that is sold many many thousands of times, I think it would make sense to build it "better". Fun fact: there was talk to start billing consumers apparent power instead of real power as well, go figure ;-)
@@TinkertubesLab They will *never* get away with billing consumers the same amount for j MJ of reactive power as for 1 MJ of real power! A high school leaver knows enough to prove this is unfair. The householder cannot be held responsible for the resistance and inductance of the cabling from the transformer station to their own home, which are altogether random, let alone everyone else's; and just one person drawing an extra j VA of reactive power in this messy system of distributed impedances will never cause the total real power consumption to increase by anything like as much as 1 VA, even in the worst case. Maybe the dinosaur fossil fuel companies would like to squeeze every cent out of you they can get, but soon they will be outnumbered anyway.
@@bluerizlagirl They got away with pretty weird things, so I wouldnt be surprised at all if they manage to do that as well. Also, knowing what people sit in governments around the globe, I would be happy if there were at least some highschool leavers in there at all xD But to be serious: I worked for a company that is pretty strongly related with the VDE and IEC, having people sitting in the normative parts of these organisations. There were, at that time, some serious discussions on how to be able to make the system fair, while still being able to make you pay. That was.... more than 5 years ago now though, I have no clue what the current state of affairs is.
@@TinkertubesLab Several places already bill domestic consumers based on apparent power or apply a poor power factor adjustment. It's a lot more common with industrial consumers but it isn't unheard of in the home market. If electronics manufacturers keep up with the slopy designs I can see it becoming more common as it puts a higher load on a lot of the distribution network.

@@tasherratt exactly that is what I fear, if we continue to just throw out tons and tons and tons of crappy designs :)
'E1' probably stands for Electrolytic [capacitor] 1.
That was waaaay to logical to come to my mind 😅
BigClive one moment please was nice
I might have watched to many of clives videos in recent times xD
Struggling to find anything nice about it!
