Hand-crank phone charger in 5 minutes!

Instead of using electricity to spin a motor, we'll spin a motor to generate electricity to charge a phone!
Parts for this build:
The main thing is the motor, the one I used it this one:
www.servocity....
www.servocity....
Other than that, the only things you really need are:
PVC pipe (or anything else you can use as a crank)
LM317
a car phone charger
a few electrical components (I used a 220 & 680 ohm resistor, and a 1uF & 10uF capacitor)

You are so amazing ! You really deserve more subscribers ! Your Jarvis build was so much more better and cleaner than other KZbinrs !

[@itstriggy4814]

Thank you! :)

[@jokulainen2376]

I really would like to see this working with the exercise bike!!!

[@coondogtheman]

Why don't you just hook the motor directly to the car USB charger and charge that way. The charger has all the required circuitry built-in to make 5 volts and all you do is connect two wires.

I love this channel, you partially inspired me to become a engender when I grow up 👦🏼😉😄👍🏻😎

francesco mannarino wat kinda gender?

[@mars4736]

Can you add for totally beginners what will it be needed to make this?

[@itstriggy4814]

I love your videos man! I would also love to see the exercise bike or some other device like that.

[@itstriggy4814]

Hey Zack, thanks! Glad to hear it

[@Phos679]

Idk why but it makes me mad that you don’t have over 1 mill

[@ianrafaeltoh7679]

Using a linear voltage regulator with a dc motor like this is not efficient and will cause low current output cuz the regulator dissipates most of it as heat. It will be ideal if you use a buck converter cuz with those, there is far less energy loss regulating the voltage while keeping the output current close to the input current generated from the motor cuz the buck converter uses less current than linear regulators.

[@Randomness67]

It's funny you mention adding it to a exesrcise bike as that is the reason why i am watching this video

[@coding32111]

I am adding it to a real bike! Did you make yours yet. I want to make it but not wanting to spend much

[@Randomness67]

@@coding32111 That's pretty cool. Naw not yet I don't have the confidence in my skills to get anywhere close to finishing. Yeah that's fair and same here also why I haven't built one yet.

As soon as you connect a load, the current induced in the coil will be able to flow and therefore create a magnetic field of their own. This will oriented in the other direction, so that it hinders the rotors movement. Bigger loads will draw more current and therefore more resistance when turning. What is the purpose of the capacitors in your circuit?

[@itstriggy4814]

Following the LM317 documentation: " Performance may be improved with added capacitance as follow: • An input bypass capacitor of 0.1 µF • An adjustment terminal to ground 10 µF capacitor to improve the ripple rejection of about 15 dB (CADJ). • An 1 µF tantalum (or 25 µF Aluminium electrolytic) capacitor on the output to improve transient response. In addition to external capacitors, it is good practice to add protection diodes, as shown in figure below D1 protect the device against input short circuit, while D2 protect against output short circuit for capacitance discharging. "

You can teach me a lot

[@epoch4116]

Are there more in depth explanation and demonstration on how to solder the board and how the wired connect? Im going to make this for my school project. I started getting confused at the voltage regulator part. Im a beginner.

[@itstriggy4814]

The wiring is just like the diagram at 2:07, just replace R1 with 220ohms and R2 with 680 ohms. More info on the LM317 here: kzbin.info/www/bejne/f5utiIp9hc-WY9k&ab_channel=Afrotechmods A soldering tutorial: kzbin.info/www/bejne/h6HWaqqliqyerKs&ab_channel=oneTesla

[@zscubing5546]

the reason of the hardness of the cranking is due to the gearbox attached to the motor to decrease its KV and RPM assumed values which in gearbox motors are good for and for cranking measurements which in turn creates good voltage values which are nearly acceptable

[@Xx_BEAST_xX]

Hey bro love your vids

[@Xx_BEAST_xX]

And please remember me when you are a big youtuber

[@gianfrancopurpura8112]

Why are they always limited to a crank to generate energy? what happened to the spring-loaded toys?

[@NotPofkp]

How's the progress on the boxing bot? Loving the content at the moment and it's looking sick.

[@j.vincento7152]

Can a large wind up (toy motor) be used to crank it?

[@narrativeninja]

from what i learned in college any dc monitor can be rotate in reversed and use as generator, in real application can all motors can be used?

[@suave617]

Why hasn’t anyone built one and sell them at gyms, everyone goes to gyms. Why not make use of all those bikes and make electricity. It’s a win win.

[@fedcruz9855]

The answer to your question is magnetism

[@FreeKanal]

Hi i have hand crank generator that is able to give me 35watt of power. The problem is that when i try to charge my phone with it, it only charges at 0,45A max.... phone charges but why it cant charge at 1,5A ? It would be only 7,5W. when i am turning crank i feel changing resistance(Load is switched?) on the handle as the phone battery tries to draw more current, but every time it tries that it stays back at 450mah and cant even climb to 1A. Where the problem is? How to solve it? I think it is some battery protection circuit that tries to draw to much current(maybe 2A or 3A) then the resistance on the handle is much higher so during handle rotations voltage drops and it starts again from 0,45A

[@nicolasrodriguez9518]

What if u replaced a bike but the pedals is the exact same thing(pedal to charge a phone)? Edit: didn’t watch the end my bad

[@williamkalal7793]

inductance capacity below 300 miliamps is kinda of a waste of time in that most heat and positive charged electricity will be grounded by heat sink.

[@TodayFreedom]

Should’ve put a gear system on it.

[@itstriggy4814]

The motors are geared. See how there's two sections to the motor at 0:20? The top section is a gear box. An un-geared motor would basically never spin that slowly.

[@harryalza0726]

Ur awesome 👏

[@Saikohack]

Use a super capacitor

[@mahbibi2679]

thanks alot

[@rengaiyengar1709]

How much time it takes to charge 100% a Galaxy S8 kind of smart phone ?

[@jokulainen2376]

I wanna ask that what are those three big round black things and the two blue things on the far right on 2:36

[@itstriggy4814]

Those are 3 capacitors and 2 terminal blocks :)

hey, what are the 2 diodes for?
