So awesome! Thanks for sharing. I can see so many uses for this. I live in Saskatchewan, Canada, and this morning it is -30c with a -40c wind chill. There are so many times when even having the block heater plugged in doesn't make a difference when the battery is basically a block of acidic ice. A little further North of where I am, a dead battery could mean a dead driver in the winter. This little device could save a lot of lives in the future! Great job!
canada: cold kills you italy: poverty kills you, hunger kills you, heartquakes kill you, rain kills you, volcanos kill you damn man, you live better than we folks down here
It will not save the driver at minus 40 degrees. Need a real system, not this toy. Such a system exists in Russia. For example: MSKA-108-16-P Rated capacity: 108F Rated voltage: 16V Overall dimensions: 245x100x105 mm
Truly some awesome energy conversion there.. whether hand cranking over time to facilitate a quick power hungry jump start or when you used the drill, which was definitely something to step back and sort of go "whoa" over. This is one of those things everyone needs to own. These would also be great for people in countries with poor power distribution. Someone could just ride a bike generator for a little while to have some light, or even run an inverter for a little while like you did for various devices. If I was in that kind of situation I'd pedal my brains out and just look at it as daily exercise.
Very nice unit! I made one just like that using super caps and a small 3 phase motor. I think it had a 3 to 5A output. Very handy to carry in the trunk of your vehicle in case you end up with a dead battery. A++
horashia I used 500F 2.7v caps on my 40w crank generator. I've since added a full cap bank using the balance board he shows in this video to the heavy duty crank generator I recently made. In the future I'll show it. I like how compact his unit is.
something with some gearing to make for a lot fewer turns of a longer crank with (obviously) more input energy, as it looked like the existing setup was super easy to spin. so I would think you could go in that direction a fair bit and still have something that wouldn't be prohibitively hard to crank. overall super impressive!
My buddy had this steering wheel with a ball attached like you would find on a sport fishing boat. The attached ball or knob allowed for amazing grip of the wheel during the action of the big blue tuna bight . I say all that to say that I could not imagine a better hand crank than that setup. I love your videos!
Okay, thought this be Roadrunner Physics... But honest to God, you've opened my eyes to a segment of DIY that's so useful... Well done young man, very well done indeed. You've made a believer. I WILL share you on my Facebook page.
I had this idea for 2-3 years. I am glad that somebody finally did it. Mine ivolves a solar panel, and I hope that soon I will have time to post it on Instructables.... Thanks for the great video, and your hard work!
Dude... I so want to try this with my boys. A friend sent me your channel because I've been experimenting with some bootleg phone chargers for emergencies using a 9V battery & endcap, usb mini motherboard/plug into an a phone charger. Very cool channel.
You could use on old cordless drill motor and gearbox. If you find a good drill it will have a 2 speed gearbox. Make sure you can physically turn the chuck on the drill before you buy it because some have a braking mechanism to keep them from turning when off. With a drill chuck on the end of the box you can put just about any kind of handle on it. May be handy to hook other projects to. Keep up the great work! I learn a lot from this channel.
hey lazer what you can do is run 2-3 generator motors at a time off of a small gear and chain then run a bigger crank to make up for lost torque be sure to wire the generators in parallel
Fun build! With all that extra space, I'd install some lighting inside the box itself with a switch to control it. And of course, some type of short circuit protection.
my first thought is to replace the crank handle with a clutch of some sort, and attach it to a windmill so the blades can freewheel when not needed to charge
I watch this and think about the generator itself. first a flywheel, and some sort of gearing/jack shaft setup. so your 1 crank rotation you can get say 10 generator arbor rotations.
That is great... Very well done. Maybe a round disk connected to the motor with a handle on the disk? You could make the disk as big as you like also some gears that make every turn of the handle multiplied.
Awesome! After seeing your earlier videos on the capacitors, and my experience with a tiny lithium jumpstart pack (and measuring its not so great CCA), I was thinking on making such a box with a handcrank on it to always have an option to start the car, also when you are on your own while travelling. And now I see you already did this! However, I would add a couple of solar cells on it, so that it could charge be itself when you leave it behind the window. Just some cells which combined voltage is below the max voltage of the supercaps and you only need a diode, so no regulators or anything.
Many appliances that plug into such ports already have some sort of integrated fuse, so the factor of damaging such appliances is null. However, damage may occur to the superbank itself in certain situations.
@@COVENANT69 The sort of product that cheaps out on a fuse is the sort of product that is likely to incur a fault. With such high current potential why risk it, how much is a fuse? 10c?
If those super caps short out some how, Say you drop a wrench on those posts, you could be in for a world of hurt. It's probably not so fun having copper blobs scraped off your bones...
Try hooking it up to a geared bicycle rear wheel on a static frame, would love to see if it can power a washing machine or microwave for the home. One hours heavy exercise might be that's needed for a days power requirements.
Very cool and great work!! Hook those caps up to an atmospheric antennae....constant charging using the Earth circuit. No cranking...no spinning anything :)
I am looking forward to your upgraded version. I want to put one of these permanently wired into my Land Rover. I want to mount it under a body panel, so I can stick a crank handle on and crank it if I ever run the battery dead using my winch etc etc. I could have a hole in the body panel, labelled "hand crank jump start" or something like that. I could just leave the crank handle in the cab until needed.
Hum, with a gear box to speed it up a little, that could make a great emergency booster pack for cars. Un here in canada, we use them a lot, but it's always a hassle to recharge them and they the battery drys down and they become useless. I bet there is a great market for a compact system you could carry in the trunk and use it whenever needed.
Several years ago Harbor Freight was selling several hand crank gadgets to charge cell phones. They used a tiny, non-descript motor but what was the key was the multiple gears. Stepper motors produce high ac voltage but the very low torque made them useless for me. What does work well for generators, for me anyway, is geared motors with significant torque. A quarter turn will shoot the voltage up there and they are capable of doing real work.
I will build one of these as soon as I can and have it in my car... the problem with battery based jumpers is that when you really need them, they are either drained or dead... and no one has the time to maintain them by assuring its battery is charged or fresh... I assume this thing can discharge and survive months of living in the trunk of the car... really cool gadget... thanx! cheers!
You could try fixing a circular weight on the crank and attach a ratcheting pull cord so you could make it a pull start motion rather than a cumbersome cranking action?
I just chain watched a bunch of your videos, and you have great ideas! tons of these could apply directly to drag cars that don't run alternators and quickly topping off your battery inside the car between runs is a huge bonus! Great stuff
to make the cranking time shorter just use a gear system for example like for every 1 rotation you make it has already rotated the motor 2-3 times like a bike chain and gears may need to redesign the box but keeping the hand crank small would keep it convenient
i imagine having a gear assembly might aide you something to increase the rate of rotation while not increasing it for yourself though i imagine it would get more difficult to turn
hay for the crank you should use the moter that spins the tray of a microwave. they are geared and i got a cap charged up to 200v turning it by hand. also they are very small.
I like that a lot. Ten to one if your battery is flat you'll be in the middle of nowhere. What I'd really like to see is one that could start my DT466.
A geared rod can be easier on the recharge person when the generator has a weighted flywheel. One push is then followed by continued generator rotations. Ratcheted gear box can be used with the rod or half turned handle you have now. Scissored foot pedal is alt with return spring. This taps into your weight combined with leg power. Pneumatics can feed an air to an air driven motor attached to the pack when mounted in car. So many possibilities.
Capacitors are supposed to have a virtually unlimited cycle life. They do wear out eventually, but it's not dependent on cycles or the cumulative stored and used capacity like with batteries. Heat and other thermal stress, humidity entering the cap, physical damage from vibration, exceeding specified limits etc will destroy them. Capacitor lifespan cannot be measured in battery terms, or at least the number of cycles will vary magnitudes more than with any battery type.
u could add gearbox to the hand cranks so that u make higher force but less time , u could even use foot pedal and make pedalling to generate electricity
What about a circuit so you can charge them in parallel but discharge them in series. You could charge them from a "dead" car battery as long as its more than 5v, you can step it down for the caps. Once they are all charged, in a series circuit it could output enough the start the car (which the dead battery wouldn't have been able to do).
Excellent idea, I have been using a super Capacitor battery on my car for four years now. I have a spare set of Capacitors and will build one similar to this! Thank you!
This device linked to the new heated clothing elements could be turned into survival gear . Heated and insulated sleeping bags in artic areas, in cars or on life boats?
I've been trying to find a project for these supercapacitors my diesel truck cranks slow at first and then drains the battery sometimes it doesn't start. How can I add these to the battery to boost without damaging my starter?
On an old WWII movie about the Phillipines I remember seeing a hand crank generator being used to power a two way radio. Used some metal legs and was used by both arms to power it. It might have been possible to use ones legs to do the same thing with less effort. Larger muscles anyway. I'd use legs made of pvc pipe and fittings, maybe one inch or so. Another option might be to use something like a 5 gallon bucket to mount the capacitors and some kind of pedal system, similar to bike pedals.
If you know where to look you can find pretty good capacitors in a junk yard... HvAc units washers and dryers have pretty powerful capacitors often for free. They save a ton of power without them your ac lights would go dim or flip a breaker. More people should use capacitors in DC set ups with power inversion. I use a "run start" HvAc capacitor just after inversion with my solar unit. Helps chemical batteries with any type motor type device in some cases 20-30% efficiency.
how long will the box hold its charge? here is a thought - leave it hooked up in the vehicle. you only have to crank it one time, then the alternator will charge it for the next start. if the box holds the charge for a day or two, use it instead of a lead acid battery indefinitely (so long as you drive the vehicle every day or so).
you should mount the crank on the top of the box and make it a little deeper. This way the box would not have to be taken out of the car in order to be charged. it would also allow more space for capacitor banks if placed sideways and stacked vertically.
May as well continue buying the same caps since he started with those. Yes Ultracaps would be better but the caps he is using seem to work. May as well build upon the caps he already has.
A bigger crank handle is just going to turn to the generator slower... What you want is a small gearbox with a fly-wheel. This will increase the crank speed while keeping up the momentum so you don't tire so easily. Think old telephone voltage generators from WWII. They measured about the same height as your box, had a small crank, and kept turning due to the flying wheel momentum.
always great work and nice hang music in the intro.thanks for your labors and sharing freely .a Merry Christmas and a happy and prosperous New Year to you and yours
Capacitors are the new standard in European bicycle hub dynamo powered LED lighting and could also be used in automotive lighting circuits so that it wouldn't matter if you left your lights on and home lighting circuits for when the power goes out during a storm.
with a little r&d i think this could make a fine backpack model with enough energy to last quite a while doing a good amount of work. integrated gooseneck flashlight, integrated lithium battery, battery charger for cordless items, permanent volt meters. if made of 22 gauge sheet metal (saying this as a tin knocker) it'll be much lighter and much more robust. hand crank could be arranged with a square drive or something so it doesn't need to be attached always - and could even be turned with a drill. i don't know how well that would work without the numbers and considering the laws of thermodynamics ... but i think you may be able to get a net positive?
Now if you could mount the hand crank in the car, you don't have to get out in the weather to jump start the capacitors if you need to use them. Another cool hack would be to change out the battery cables for posts mounted next to the box and have about 2' of jumper cables coming out of the box that you clamp onto the post that way if you need to jump a friend you can just pull the box out and hook up the jumper wires to their battery, or if you want to sit inside the truck and run a laptop you can put the box inside. I'm curious how well those 6 caps run your headlights at night.
what if you kept an electric drill in your vehicle with this device, so you could attach and run the drill, replacing need for the hand cranking charge? I'm new to DC etc so forgive if i'm way off.
90v PMDC motors might do what you need if they have a low enough operating rpm. I have one I got off of eBay that will probably do 14v with a 3:1 gear increase hand crank. look for ametek or Dayton or something else.
the caps are the storage for the electric charge the idea of the flywheel is that instead of cranking the hand multiple times , you just spin the fly wheel and it will continue to spin for a while
razie85 Yes. As shown at the beginning of the video without the diode it behaves exactly as if there were a large flywheel attached to the crank and geartrain. With the diode it behaves the same only you have added a 1 way clutch.
Would putting 12v of solar cells on one side of the box work? Could keep the box by a window to charge when you weren't using it, and to augment cranking it when you needed to do that. Nice little project. I especially liked you running the small inverter off of it.
if your going to use this for boosting cars you should upgrade the wire size between the battery posts and the capacitor bank as well as beefing up the connections on the circuit board between the caps
im impressed all to hell. we started out with cars and a crank and now were back to a crank and a car. should do a permanent mount under the hood, longer crank, less cranking involved before the caps are charged.
Have you ever considered using a constant power DC-DC converter to keep the voltage flat and regulated for certain applications (to prevent the capacitor's exponential discharge curve) where undesirable?
So awesome! Thanks for sharing. I can see so many uses for this.

The electrolyte in the capacitors could still freeze tho...
Ey, if it's that cold, why don't you give the battery a heater as well? I mean, if you're gonna hook it up to mains anyway...
@@olliestarkey6022 You don't know what poverty is unless live you're in a 3rd world country you stupid fuck

How is it ensured that the alternator that gives 60 to 100A does not destroy the BMS, can it withstand such currents?
I just wanted to thank you for sharing all of the amazing things that you do with the rest of us. You research is truly inspiring.

Would 120f 2.7 will work?
horashia
Place 2 cap banks of 6 in parallel.
M2ripper Metin2 Sure does.
this is an amazing jump starter kit thingy, you dont have to worry about keeping it charged!
Attaching something like an arc lighter to the output would make for a really good survival tool for starting fires

Yes, it was very easy to spin. A better geared generator with a large size crank will be a much better fit for this project.
Joanna, that has a worm gear. You cannot spin the output shaft of a worm gear assembly and spit the motor. Worm gear will act as a rack in that case.
Joanna Brown You are not spinning a wormgear from the output shaft.

It's incredible what super capacitors can hold nowadays.
That should increase your solar product line quite quite substantially.
Love projects like the one you made, making your own energi is always interesting to me.
Its always fun to see your stuff , with a bank large enough with a alternator stationary bike you could ride a home while staying lean.

Multiple generator units with a larger handle to offset the opposing mechanical force.
More power in the bank means a faster charge, yeah?
Use planetary type of gears for the crank ? that way you have to do less revolutions with your hand but its a bit harder to spin.
I saw a similar setup a few years ago.
It would be really cool to implement this in racing vehicles.
You need to mount that just above the bumper behind the grille and get an olde timey hand crank for a model T or something.
This is great man! You should patent it and make a commercial version 👍💯. The ones on the market don’t have a cranking hand generator.
What is the lifespan of the capacitors or how many charges will it hold until it does not hold charge?
I would like to know as well
Capacitors are supposed to have a virtually unlimited cycle life. They do wear out eventually, but it's not dependent on cycles or the cumulative stored and used capacity like with batteries. Heat and other thermal stress, humidity entering the cap, physical damage from vibration, exceeding specified limits etc will destroy them.
Capacitor lifespan cannot be measured in battery terms, or at least the number of cycles will vary magnitudes more than with any battery type.

Once they are all charged, in a series circuit it could output enough the start the car (which the dead battery wouldn't have been able to do).
How about using a ratchet wrench and a flywheel to keep the tork steady?
Excellent idea, I have been using a super Capacitor battery on my car for four years now. I have a spare set of Capacitors and will build one similar to this! Thank you!

Erosion139. he would better buying ultra caps on. kinda suprised these tiny caps can start the car
May as well continue buying the same caps since he started with those. Yes Ultracaps would be better but the caps he is using seem to work. May as well build upon the caps he already has.
A bigger crank handle is just going to turn to the generator slower... What you want is a small gearbox with a fly-wheel. This will increase the crank speed while keeping up the momentum so you don't tire so easily. Think old telephone voltage generators from WWII. They measured about the same height as your box, had a small crank, and kept turning due to the flying wheel momentum.
always great work and nice hang music in the intro.thanks for your labors and sharing freely .a Merry Christmas and a happy and prosperous New Year to you and yours
Capacitors are the new standard in European bicycle hub dynamo powered LED lighting and could also be used in automotive lighting circuits so that it wouldn't matter if you left your lights on and home lighting circuits for when the power goes out during a storm.
So if I use a 1000 watt solar with the same 72 caps I can power my 2kw induction motor in my wood works shop
with a little r&d i think this could make a fine backpack model with enough energy to last quite a while doing a good amount of work. integrated gooseneck flashlight, integrated lithium battery, battery charger for cordless items, permanent volt meters. if made of 22 gauge sheet metal (saying this as a tin knocker) it'll be much lighter and much more robust. hand crank could be arranged with a square drive or something so it doesn't need to be attached always - and could even be turned with a drill. i don't know how well that would work without the numbers and considering the laws of thermodynamics ... but i think you may be able to get a net positive?
Now if you could mount the hand crank in the car, you don't have to get out in the weather to jump start the capacitors if you need to use them. Another cool hack would be to change out the battery cables for posts mounted next to the box and have about 2' of jumper cables coming out of the box that you clamp onto the post that way if you need to jump a friend you can just pull the box out and hook up the jumper wires to their battery, or if you want to sit inside the truck and run a laptop you can put the box inside. I'm curious how well those 6 caps run your headlights at night.
what if you kept an electric drill in your vehicle with this device, so you could attach and run the drill, replacing need for the hand cranking charge? I'm new to DC etc so forgive if i'm way off.
Can this be upscaled with more rows of capacitors in parallel?
90v PMDC motors might do what you need if they have a low enough operating rpm. I have one I got off of eBay that will probably do 14v with a 3:1 gear increase hand crank. look for ametek or Dayton or something else.
Can you do a geared option? for the hand crank so you dont have to crank like a mad man?
the one he used looked like it had a gear box on it, sounded like it to.
Squid Of Overkill it is a geared motor
could you add a heavy flywheel to it and use a rope to get some speed /momentum in it
like pull starts on old engines
The capacitors are the flywheel.
the caps are the storage for the electric charge
the idea of the flywheel is that instead of cranking the hand multiple times ,
you just spin the fly wheel and it will continue to spin for a while
razie85 Yes. As shown at the beginning of the video without the diode it behaves exactly as if there were a large flywheel attached to the crank and geartrain. With the diode it behaves the same only you have added a 1 way clutch.
Would putting 12v of solar cells on one side of the box work? Could keep the box by a window to charge when you weren't using it, and to augment cranking it when you needed to do that. Nice little project. I especially liked you running the small inverter off of it.
if your going to use this for boosting cars you should upgrade the wire size between the battery posts and the capacitor bank as well as beefing up the connections on the circuit board between the caps
A bicycle left side crank might work. You would have to repale the pedal with a suitable handle of course.
im impressed all to hell. we started out with cars and a crank and now were back to a crank and a car. should do a permanent mount under the hood, longer crank, less cranking involved before the caps are charged.
Have you ever considered using a constant power DC-DC converter to keep the voltage flat and regulated for certain applications (to prevent the capacitor's exponential discharge curve) where undesirable?
could you put in some 18650 in the circuit 2 to help with the charge or with the batteries take too long to charge with a hand crank?
You could put one of those LED lamps inside, it would work well with the clear cover
Have you thought of using a gear reduction to give you more turns on the generator per crank on handle?
