Making My Own Power! Building a Hand Crank Generator

Today we build a small hand-powered 5v DC generator. This project can be used to power some small led's or a cellphone, or even just to play around with power generation on a small scale. (Note: I didn't actually use this to charge my phone at the end as I don't fully trust my 5v regulators with the life of my phone. This was just a proof of concept, and this specific motor and setup probably don't produce enough current to do what was shown here.)
Crank Arm STL File: www.thingiverse.com/thing:321...
Parts list:
1x Nema-17 Stepper Motor
8x IN4001 Diode
**2x 50v 3300uF Capacitors
1x L7805CV Voltage Regulator
Breadboard/Jumper Wires
**This part can be changed out with any other similar capacitor that has a rating over 5v and a large capacitance

i think i finally understod something about electronics, thanks mate

"DA FULL BRIDGE RECTIFIAH!" Sorry. It was stronger than me.

@BackYardScience2000 3 года назад

Very cool, man! I may buy the materials soon to try this myself and use your video as a walkthrough. Thanks for posting!

@CarbonCoil 3 года назад

Sure thing! Let me know how it turns out, or if you have any other questions

@DBXLabs 3 года назад

Very epic fast video turnaround. Also awesome video.

@CarbonCoil 3 года назад

Glad you enjoyed it!

@user-di4bt7qu2i Год назад

Awesome video. I'm going to duplicate what you did in the video as part of an emergency kit. Thanks!

@chrispirolo170 Год назад

Great teaching video!!!🎉

@CarbonCoil Год назад

I'm glad you liked it!

@iLoveTheSyncButton 3 года назад

Maybe try a coldcap+stepdowm combination, that would be a lot more suitable. Great video though! I like your uploads!

How many max voltage output at that motor when you crank it

@shehabshehabeldakamy3752 Год назад

could've made the cranck a bit longer so more to the input and a larger torque

@matthewjason5330 3 года назад

great vid i wont be able to do it but you kow if in in emerengancy and have a stepper motor and some bread boards in my pocket i might get it to work

@CarbonCoil 3 года назад

Haha yeah

@acmefixer1 Год назад

What it is, is a Full-WAVE Bridge Rectifier. Originally there were two plates and a cathode in a Full-wave rectifier tube, which worked with a center-tapped secondary on a transformer. But if you don't have the center tap, then you use a Full-wave bridge rectifier. There is no such thing as a full bridge rectifier in a Dictionary of Electronics Terms.

@fredericaacademy1 Год назад

Can you add super capacitors and store the power generated from the crank?

@CarbonCoil Год назад

Yes! Other power storage options such as rechargeable batteries would work as well.

@zoheb4you2002 2 года назад

U can attach farad capacitor to it for better use..

@stupidscruff5794 Год назад

Yeah and then you can start a fire too! 😂

@tobiask8490 Год назад

Nice simple project. Buthow much power can you generate like this? The motor seems to turn very easily.

@CarbonCoil Год назад

Probably not much practical power. To generate more, a higher speed would be required. This also isn’t the ideal setup as usually geared DC motors are used for hand crank generators, but this was just a proof of concept using what I had on hand.

@tobiask8490 Год назад

@@CarbonCoil thabks for the reply. I already tried geared dc motor and got a few watts, but using stepper motor would be more elegant

@user-be7tk6rv3g 9 месяцев назад

I am new to this field and I have looked for some information to make a DIY generator at home. It is the most helpful tutorial including what parts you use and why u are using! But I still have some questions after watching this. 1. Why did you connect the parts in order of generator -> rectifier -> capacitor -> regulator? If I change the order of capacitor and regulator what problem will I have? 2. Regulators make consistance voltage but I think It will make unconsistance current instead. Is it okay to charge something like phone or batteries?

@MrBesharam Год назад

Can you make PCB board of this design to make is easy

@princedemiterios2488 Год назад

Great , keep up the lights on 👍🏻

@TheSpektacle 3 года назад

Is there a way to tie the internal coils together, like in series? or parallel? Or will this cancel the phases?

@CarbonCoil 3 года назад

Not sure about tying the internal coils together. I don't think this would work because the two sine waves are not in phase with each other. However in this design they are combined after being rectified to DC.

@TheSpektacle 3 года назад

@@CarbonCoil thanks. I think one way (series OR parallel) will cause the phases to cancel each other, hence (much) less power output. True? My goal is to use only one bridge rectifier for less voltage loss.

@CarbonCoil 3 года назад

@@TheSpektacle This might work, play around with it a bit and let me know if it does.

@akhtarmisba5868 Год назад

Can you give the link for the full scheme on the breadboard

@CarbonCoil 11 месяцев назад

The schematic is visible at 2:00 in the video

@Emili07411 3 года назад

I don’t understand most of the things that your saying but still pretty cool vid. (Ps. Where did you get the name carbon coil?)

@CarbonCoil 3 года назад

Thanks! And as far as I know theres no real meaning behind the name, I'm really bad at coming up with names so it was somewhat random.

@stupidscruff5794 11 месяцев назад

Which stepper motor is this? Looks like a Nema 23

@CarbonCoil 11 месяцев назад

It’s a nema 17 stepper, but any stepper motor form factor should work

@lakshmann9825 2 года назад

whrwhat if i do it in to and fro motion ....... will it provide stable voltage

@CarbonCoil 2 года назад

Yes, because the voltage that comes out of the stepper is already AC, a large enough smoothing capacitor will provide a stable voltage when turning back and forth in both directions.

@CashOnlySeb 3 года назад

Where can i buy this

@CarbonCoil 3 года назад

Currently not for sale anywhere that I know of. Its just a design I found online and replicated. You can however find hand crank mobile phone chargers and flashlights on Amazon and Ebay.

Use gears inbetween

@gianfrancopurpura8112 Год назад

Good boy! and congratulations! But building a hand crank generator with a wind-up clock ... would be better !!

@TheRealSly14Cat 3 года назад

What's the amperage? An LED only needs 20mA, a phone needs 1A at least...

@CarbonCoil 3 года назад

The amperage will depend on what specific stepper motor you use. You can look up the data sheet for your specific motor to find some of this information.

@xcruell Год назад

No it doesnt "need" 1A, it CAN draw up to 1A Less will work fine

@rm6857 Год назад

i would say less than 100mA

@Ich8in Год назад

And the current? Not a single word about the most important value for charging?

@rm6857 Год назад

it could be like tens of miliamps

Brilliant idea my friend, this stepper motor can be coupled to the steering wheel of the bicycle pedal, in order to power a lighthouse while pedaling ❤🇧🇷🇧🇷😉👍 subscribed👏👏👏👏 "@arduinomaquinas" thanks by idea !
