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?
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.
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.
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.
@@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.
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.
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.
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.
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 !
i think i finally understod something about electronics, thanks mate
Very cool, man! I may buy the materials soon to try this myself and use your video as a walkthrough. Thanks for posting!
Sure thing! Let me know how it turns out, or if you have any other questions
Awesome video. I'm going to duplicate what you did in the video as part of an emergency kit. Thanks!
Does it works like in the video?
Very epic fast video turnaround. Also awesome video.
Glad you enjoyed it!
"DA FULL BRIDGE RECTIFIAH!"
Sorry. It was stronger than me.
Maybe try a coldcap+stepdowm combination, that would be a lot more suitable. Great video though! I like your uploads!
Thanks!
Great teaching video!!!🎉
I'm glad you liked it!
How many max voltage output at that motor when you crank it
Can you add super capacitors and store the power generated from the crank?
Yes! Other power storage options such as rechargeable batteries would work as well.

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

@@CarbonCoil thabks for the reply. I already tried geared dc motor and got a few watts, but using stepper motor would be more elegant
Great , keep up the lights on 👍🏻

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
Haha yeah
could've made the cranck a bit longer
so more to the input and a larger torque
U can attach farad capacitor to it for better use..
Yeah and then you can start a fire too! 😂
Which stepper motor is this? Looks like a Nema 23
It’s a nema 17 stepper, but any stepper motor form factor should work
I gatta say this, I'm feeling Micheal reeves Vibes here
Good boy! and congratulations! But building a hand crank generator with a wind-up clock ... would be better !!
Wow nice
Thank you! Cheers!
Is there a way to tie the internal coils together, like in series? or parallel? Or will this cancel the phases?
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.
@@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.
@@TheSpektacle This might work, play around with it a bit and let me know if it does.
Can you make PCB board of this design to make is easy
Can you give the link for the full scheme on the breadboard
The schematic is visible at 2:00 in the video
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?)
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.
Where can i buy this
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.
@@CarbonCoil ok thank you
whrwhat if i do it in to and fro motion ....... will it provide stable voltage
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.
What's the amperage? An LED only needs 20mA, a phone needs 1A at least...
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.
No it doesnt "need" 1A, it CAN draw up to 1A
Less will work fine
i would say less than 100mA
Use gears inbetween
And the current? Not a single word about the most important value for charging?
it could be like tens of miliamps
@@rm6857hate the way all these videos gloss over that
I did it about 500 ma for nema 17 but in emergency it is enough to make a call
OK
