Joule Thief Hupcharger

Energy recycling. 12v battery charging 18v battery. How to use an LED breakover voltage to create a reservoir of higher voltage for charging batteries.

It's true that electrons flow from negative to positive, but in electronics it is just simpler to use conventional current flow. All the symbols are pointed that way and nearly all the reference material is written that way.

[emichael]

would it make a difference if the ferrite rod was made with multiple ferrite discs stacked to 8"?

Current flow goes back to the early electrical research most notably by Michael Faraday. He considered current to be the flow of positive charge and created the whole concept of current as a kind of fluid.

Years later we understood that current was actually the flow of electrons, by which time however there were MANY concepts explained by "conventional" current or positive flow hence the convention stuck (as it makes zero practical difference, only a physical difference in the detail) and as explained by others ALL the symbology used in electronics is based upon "conventional" current flow i.e. positive current flowing from anode to cathode in a circuit. It is confusing in the extreme to change this convention since every electrical and electronic engineer on the planet knows it the "conventional" way

[rogerd]

wait... I was taught by Devry that current flow was from positive to negative, but Electron flow was from Negative to positive

The Brush motor in series with the LED will read the EMF return from the motor. ???

[morpher]

meter readings won't be correct because of the AC RMS on the line.

[rogerd]

what keeps the battery charging circuit from overcharging the 16 volt batteries above their voltage? trying to charge them to 120 volts?

[ionizationx]

Hi arkiver, do you have a video of Herman Andersons water cell?

[rogerd]

you measure the current through the led and the voltage accross it multply the current by the voltage will give you the wattage

[jonbigman]

It gets it's efficiency from the bifilar method or interposing windings. When the pulse goes through the primary it doesn't have a restriction and the voltage only gets a boost and does little to reduce the initial current. By interposing the secondary between the winds of the primary you create an inductive diode. The diode is based upon the same voltage levels differences of the material itself. The secondary should not have a huge impact like in an ordinary transformer. You want this control to be all potential so the losses are meaningless. This is why they use a toroid core to lock away the magnetic field. The transforming happens in the interposing polarities of the bifilar wind. Regular gauge rules apply. Higher voltages need less gauge and higher currents need bigger gauges. More mass in the higher current section means higher magnetic fields in the toroid. So core balancing to the expected current output needs to be calculated. Any leakage or core saturation would only increase the output due to the secondary being around the core partially. A sort of self containment but only so up to a degree. Stressing matter in such ways can be very, well stressful.

[tonyrebeiro]

You're confusing current flow & electron flow. Current flows opposite to electron flow.

[aussienature]

watch on x2 speed and it's almost a normal speed video. lol

[hydniq]

at 7:50 your circuit goes into self oscillation you should do some tests with that.

[hydniq]

you think the battery is making the circuit oscillate?

[bjl]

it will work better if you wind the coils on top of each other and remove the diodes and capacitor.

[electronicdiy]

You should a
It seems the circuit requires improving by adjusting the trigger current of the transistor because it only uses the 72 turns coil resistance that could be not enough limiting base current, since the TIP 3055 is a power transistor it will amplify small base current to important collector current and the electrical power Ic*Vce converts into undesirable heat power...

[sailingcapedissappointment]

Hmm .. 🤔 I read somewhere that LEDs are actually field effect transformers .... and that nag's at me for some reason ..

[Dennis-mqor]

You are comparing RMS power to PEAK power.

[devinmccloud]

I disagree completely. Current flows in both directions. One can not move without the other. Ed Leedskalnin.

[thuthamgia]

Why you do it. It not like overunity . COP < 1
