Solved the charging issue on my supercapacitor Bluetooth speaker project. In conceptual terms, this project is finished 🙂

I found this video very insight full i just have a burning quetion.
Since the Converters are connected in parrallel why is the current not summend on output?
Utilizing 12 volt input on a 24v solar panel (Vco)
Can you put two solar inverters in series to double input voltage Vco solar panels
Julian Ilett Can only find one diode? I expected more of you Julian. lol
is it possible to control those converters using arduino or stm32
What are the buck boost converters in the video?
Either two Schottky diodes (with drop compensation) OR putting a, possibly opto-isolator driven, switch to toggle between the supplies so that when any lights come on they trigger the switch to kick over to the 0.5A supply while turning off the high-current unit would do the job I think. The diodes would be far easier, but the switch would be dumb fun and a more fun solution.
How about single power supply with two different resistors in place of the variable one switched by an arduino? Or one of those arduino controlled variable resistors? (X9C103S)
Hi Julian! I just wanted to say I'm watching your channel from nearly bunging… AND
I think there is a fundamental flow in your setup. YOu need a a galvanic isolated power supply to ich converter to get this work. //Regards from Sweden
A rolledup tube of cardboard around the red led and a photocoupler or light sensing transistor in the other end of the tube facing the red led should allow switching when the red led turns on.
The DP30V5A DC power supply voltage & current regulator would do the same thing for you all in one. You just dial in your voltage and current, when it reaches what you have chosen, it will trickle charge or shut off. But I think you're just having fun with modules! 🙂
Wouldn't a constant current constant voltage charger do the same thing?
You just set to the voltage you want & max amperage you want. It charges at that Max setting. Then like a lithium ion battery charger, when it reaches full ( whatever you have set as max) it will trickle charge after that & just maintain.
