Supercapacitor Playground

Playing with supercapacitors

[YrubullyGD]

this is what youtube should be, people recording themselves just having fun and not a money maker

Can you keep adding converters until all the power in the cap is lost in the inverters. Should not take to many 😅😂

On the ZK6522, what is the 2 port connector next to the display connector for? Just labelled EXT

[TheEmbeddedHobbyist]

Try using batteries the leds will flash for a lot longer, ❤

Maybe the dud cap is stuffed with coke - should be quite profitable if so!!!!

Its a shame that, with those spindly legs they are not built for handling very heavy currents.

12:04 Large pulse current will shorten life of capacitors. AA high current will waste energy from cell internal resistance (guess energy loss: zinc chloride AA >90% & alkaline AA >50%, depending how high the current is of course; NiMH less, not sure the amount).

Is there some special property of supercaps that the LEDs don't need a current limiting resistor?

[SpeccyMan]

My playground is either my Raspberry Pi 5 or my Z80 based SBC built from a kit.

Looks like you're having fun. Nothing wrong with that.

500 Farads? How is that even possible? I don't buy it. The radius of a sphere with a capacitance of 1 farad. Is 9x10^9 meters in size. A sphere with a radius that size is 25 times the distance the Earth to the moon.

What a waste of time, pointless other than to show the fake products you get. You didnt measure ESR, very important nor try and estimate the actual capacity of the items by timing at constant 1A ie to determine the capacitance value of my capacitor I simply have to measure the time interval in seconds while charging or discharging at 1A between 1 Volt and 2 Volts. Or 1.5 Volts and 2.5 Volts, any 1 volt differential should yield the same result.(As long as my charge current is constant) So my 100 Farad +-20% capacitor should take between 80 to 120 seconds to go from 1 Volt to 2 Volts. Not rocket science
