V2 DIY Hand Crank BoostBox - Capacitor Power Can Start a V6 Engine

[@planecrazyish]

Hey Lasersaber! Hope you're ok. Missing your great solar and super capacitor projects, hope you will be back with us soon! Best wishes from New Zealand.

[@Jwightdvm]

Great build. I'm really interested in doing one of these. A few quick and very minor suggestions: If you attach the capacitors to the lid instead of inside the box you can work on components inside without disassembling them. Also, hot gluing a few extra fuses inside the box will be a big plus if one of them ever blows.

[@WideVisionMetalFab]

Awesome! And just a suggestion, using a bridge rectifier would allow for the crank to be turned in either direction to create power.

[@диванныйкопатель]

отличная идея!

[@rejeanbeaudette6929]

ElectroBoom would approve

[@johngrey2049]

You could make a few solar cells on the top, so it always keeps its charge when you place it in front of a window. Ready for any emergancy. Its a wow invention.

[@GeoFry3]

run a wood hole saw backwards if you want an easy way of cutting nice clean holes in plastic. spade bits don't work too well. running it backwards keeps it from grabbing and gives a smoother finish. Very cool project. I'd like to build something like this into my 4x4. Weak battery, just do a little cranking and you can get it started to get home. don't really need it. already have a small solar panel mounted that keeps a float/slow charge on it, but hey it may happen at night!

[@jmelcher1849]

Love your design I expanded on it. Heavy duty polymer tool box, perminent magnet 800w motor, same that windmills uses, weld about a 14lbs fly wheel to the end of the motor (you'll hand spin this to start it) connect to a plexiglass box. Inside plexiglass box make a 1:642 gear train. Fill plexiglass box with gear oil for reducted friction, on the end attach a 4 ft long crank so you can get your entire body into rotation. With the brushless perminent magnet motor it doesn't matter which way you turn the generator and you'll get insane amperage and watts with your 1:642 gear ratio, just make sure you hand spin the fly wheel first. An object in motion wants to remain in motion.

[@erniehopkins2757]

I Think you should put the crank in the middle of the large surface on the larger box with a handle on the narrow edge then you can stand it up and crank your knuckles won't hit the ground. Hope this helps

[@stealthop]

im going to build this . thank you lasersaber for including the parts list and project notes .

[@aliff6893]

hi. have u build it? can u share it how it went?

Dear Lasersaber, you are a very helpful scientist for mankind. The world need you. I was very worry because I had not seen new video coming from your channel for a long long time. Best wish to all of your experiments, please say hi to your family and your chickens in the back yard. ....From Arizona USA.

[@sthrnsqrl1]

A shame. One of the coolest projects I have seen on YT in a while, and you removed all mention of it from the net, except for this video, which is now useless without a parts list.

[@3D_Printing]

The turning of the handle got a saw blade and a drill to turn; pure science :) Well done

[@CesarUbach]

You've caught on to something awesome. I've been waiting for this video for a while. I'm building mine ASAP. You're awesome, Man.

[@valveman12]

Hey, Lasersaber I used a FW bridge rectifier on my crank generator so it makes no difference which way you turn the handle. MY generator is not as big as yours but good for charging phones and running LED lights. BTW: Like your channel.

[@NuclearRobotHamster]

In theory it should also charge faster as the single Diode will block half of the power cycle(??) of the handcrank, while a bridge rectifier will allow both halves of the power cycle to charge the capacitor Bank.

[@NuclearRobotHamster]

@MultiDavid997 so there is already a bridge rectifier or similar inside the hand crank generator.

[@NuclearRobotHamster]

@MultiDavid997 most bare rotary generators will produce AC unless there is extra circuitry to prevent it from doing so.

[@NuclearRobotHamster]

Sorry, i checked in the meantime. It seems I forgot my highschool physics quite a bit.

[@NutScrewGamer]

Brushed permanent magnet motor outputs DC if I'm not mistaken

[@srbontrager]

Don't know if someone has pointed this out yet. At 6:21, you place your adhesive tape over the pressure release vents of the capacitors. This could affect the proper function of those vents if the capacitors need to safely vent off pressure due to the failure of the capacitor. Instead of a slight pop and a hiss. It could now become a KABOOM! Other than that, I'm planning on building one of these to use as a jump pack.

[@axiomV]

Made this project almost two years ago, didn't use a bridge rectifier to minimize losses from motor to the capacitor bank . I didn't put the supercaps lasersaber used in his videos (EATON 400F 2.7V) and had the geared DC motor used in his first video, but i can surely say that as a project it has potential. Yes batteries store way more energy but you can charge this in far less time than a battery and you dont have to worry about battery lifespan or charge cycles and weather conditions, it's also way lighter than a car battery (so portability is a plus too).

[@edugio]

American talent has no limits and you are one of the US talents. Congratulations excellent video.

[@Martinko_Pcik]

Great build. I built a supercapacitor bank for spot welding. It can generate 1500Amp impulses. Adding a crank to it is a great idea.

[@daviddavids2884]

thanks for posting. nice work. here are some late thoughts. imo, at 7:25, you were well on the way to cooking that diode with the soldering iron. thanks for the info about the small hand-crank generators. i am guessing nominal output would be about 18 watts. in lieu of replacing the pm motor, another stage of step-up gearing could be added, to 'speed things up'. you may know, in an application where a high-speed pma is desirable, the stator coils can be connected delta. then, output rises Amps over volts. lenz force drag at lower speeds is initially less, then gradually climbs with rotation rate; output power (watts) is roughly equal to stator coils connected wye/star. cheers in case you or your subs might be interested, here is a link to a video in which, just maybe, overunity is achieved, on a table top. the video appears to show an Energy Gain of 60-plus percent; where input power is about one watt and output power is about 1.6 Watts. this percentage corresponds to the Amount of Mechanical Advantage the drive motor has Over the load (generating coils), located Nearer to the center of rotation. if is is true, it is proof of my separate research, conducted in 2016. the idea is simply to use Leverage and modern power generating hardware, to Easily achieve overunity. (see the law of the lever; the wheel-and-axle, which is a Rotary, 2nd-class Lever.) see my channel for more info, if it suits. cheers kzbin.info/www/bejne/ZmeXenltgsuBedU

[@billysgeo]

Right up my alley. Not to complex, not to simple! Perfect. Subscribed!

[@walterwilhelm]

love this, It provides quiet power, No need for loud gas generators. Huge Thumbs up. Will be sharing this video and subscribing. Thank You

[@kd5inm]

When soldering a lead from your diode its important to have a good mechanical connection as well as an electrical connection. Wrap some lead around your wire connection to make it strong. I would put the binding posts toward the end where the generator crank is then make where binding posts are the bottom so the crank is up clear of the table surface so you can turn it.

[@DavidLauritz]

Awesome build! Love that you share what you are doing. You should add the possibillity to charge the unit from a wall socket.

[@iamaioshi]

One of my favorite videos!

[@craig265]

Thanks for posting this by the way..... although I would reconsider I'm putting the super capacitors in a box like that. I only say that because if you use a 5 gallon bucket it allows you to put more capacitance in there along with other components that you can open at any time as it also has a Rubber seal and a built-in handle for way less money.

[@nw7696]

Extreme longevity potential, I love it! Decomposition of the materials used to build it being the only possible downside. Otherwise, I see no reason why this shouldn't remain functional 100 plus years on. You should commission someone to manufacture and sell these for you!

[@nickdannunzio7683]

[@RJCooper2]

Built-in clamp-to-bench / clamp -to-picnic table / clamp-conveniently-to-car, eliminating cranking difficulty? Just for the record, I thought one of the worst things car and truck manufacturers ever did to auto-industry consumers / customers was to eliminate the hand-crank option fod engine starting. And, the second worst thing was eliminating the mechanical power take-off so that a family's second most expensive asset could no longer be used to help them complete tasks around their property. Thanks so much for leading the way in innovatively Reinventing the hand crank starter. There should be one of your boxes included in the trunk of every new car with an internal combustion engine, as well as a small pull start gasoline engine in electrics in which you could limp home in case of emergencies. And well they're being really brainy they could put a hand crank window option just in case Electric Windows go bad. Of course Detroit and other based manufacturers would just say well it's time for a new car and that's always been there answer instead of answering with their main responsibility / the consumer in mind.

[@gravelydon7072]

Hand crank starters were removed from cars due to people getting stupid. And broken wrists/arms. We still have tractors that are 6Volt and hand crank. But most people would never know how to start one safely. As for the PTO, yep. Jeeps had them and we have a 3-point hitch for use with one. Problem is................. you need to find one from back in the 40s-50s to use them. My pickup does have the PTO gear in its transmission and there are kits to install a 10kW alternator on that transmission. But I will tell you this, the same transmission without that extra gear is a lot quieter.

[@lucasmorton5619]

Use BLDC MOTOR for better generation efficiency! Thanks for the awesome vids.

[@dandi5998]

An Excellent product. Make it more functional....removable handcrank..adaptable to a DIY powertool to spin the crank.

[@MattOGormanSmith]

A brace and bit would've got those holes drilled in a similar manner, but with fewer intervening stages :) The boost box could be a life saver in snowy conditions though. They come into their own for starting gasoline engines when it's so cold that even a good condition battery struggles. I've seen videos where people have permanently replaced their battery with these supercap banks. Nice job.

[@MattOGormanSmith]

I remember now. They were mostly YOUR videos :)

[@ScinnerNo1]

Answering my own question :) From what I have found out a hand cranked generator delivers approximately 10-20W. If we say it delivers 20W and your cap´s hold 0.34Wh x 12 the cap bank holds 4Wh. To fully charge them with a 20W hand crank it would take 4/20 = 0.2h in other words 12 minutes, and thats at best. If you want to charge your iPhone X from empty to full (10Wh) you would be cranking for 30-60 minutes ;) Wow, thats quiet a workout guys. Carpal tunnel syndrome here I come!

[@rcayers1700]

Such a wise guy. I like it. Who needs heavy long lead cords on a remote job site!? Or jump box for starting cars when batt goes down. Can quickly charge this box off a bad batt w low voltage, then start the car w this box.

[@willybee3056]

Good job,,, I built battery replacement for my scooter... 500 f caps , it stayed charged for six days between runnings, then I saw a pcb charge balancer on evay, the ones with all the active electronics, , it only stayed charged for 2 days.... so I went back to diode bridge system.... works fine...

[@agvulpine]

I think it'd be really cool if you started using Anderson Powerpole connectors in your projects, in addition to banana/lug and cigarette lighter plugs. You've already got a decent crimper for them.

[@Ezio-Auditore94]

I like the musicalization of your channel in general

[@johnnaglic]

This is exactly what I have in mind as well, however, super caps have low voltages and you need circuitry to ensure that they operate in a balanced mode so that they don't get excessive voltage that can cause failure if unbalanced. So I am rethinking the idea using 2.7 volt caps at the moment. The other thing is that you will need to make a current limiter so that your cranking torque is manageable to not get over stressed cranking for prolonged periods of time. There is no free lunch when it comes to energy.

[@pa4tim]

You need to reflow the solderjoints of the cap and PCB. They are cold joints now. They are only connected to the pin of the cap. They need to flow to the PCB and look concave between pcb and pin. Not convex and only soldered to the pin like now. It will oxidize over time and form an increasing resistance. I think your soldering iron is not beefy enough.

[@1gizmospot]

You were making amazing content and taught me a lot. Seems like you disappeared. Has everything been ok with you. Looking forward to getting some sort of update.

[@robertmeyer4744]

TIP use a bridge rectifier and you can crank CCW or CW can make it easier for left handed use. This may be the beginning of the end to batteries as we know them!!!

[@GadgetAddict]

I think I'll check your original video. I'm more interested in what it can do and how it works than how it was made :) Thanks for sharing!

[@AnimeIsekai]

Big fan here! Are you planning to make one?

[@mr.abdalsexperiment]

Nice. Can a super cap store to much energy like this? It's really amazing job.

[@krazed0451]

Given the cost of capacitor jump starters, this is very handy info :-)

[@pyronmasters]

Any chance you can do a video on upgrading a $1 solar garden light with a capacitor? I'm from PR and I wanna upgrade 10 of my lights to share with my neighbors, we're still without power.

[@mattkul4276]

So it has been a while since u uploaded this vid, but, I was thinking.... If u were to connect a sprocket (to the crank) that is larger than the radias of the spindle on the generator. Add a belt or bike chain connecting the sprocket to the spindle. Doing this should result in less rpm on the hand crank and more rpm on the generator, decreasing the amount of effort needed to charge the power bank. Thanks for the vid.... I'm building as we speak.

[@lenwhatever4187]

It looks like it could use a clamp on the bottom for better cranking. It looks like that generator/crank size is close to the limit for a box that can't be clamped down to something... (park bench, tailgate, tree limb, whatever) Maybe carry a ratchet strap.

[@charlesholt2662]

Thanks for braking my eardrums with your drill! Thanks for the information and the DIY! I’m going to build one.

[@MrLordBaer]

[@BinjKomisar11]

Excellent work! Very cool, glad to see your still kickin'! Also, your set of helping hands look pretty helpful, a much better design than the classic. Good stuff. Peace Ben

[@jcknives4162]

Maybe add the crank to the top so you don't have to be on a table to crank? Put the carry handle on the side? I know it changes the shape of the box because of the generator... just a small thinking problem. This is really cool.

[@getinit56]

To all the people decrying the cost of this. I suggest you compare apples to apples and price a good jump box. Then check and see how long that good jump box takes to charge after it dies. This is a vast improvement and worth the little extra for its over and over use capability. One could sell these at an auto auction like hot cakes.

[@BleuCollarFndryMTL]

Cool project, I love your passion in doing this. Don't listen to the non believer.

[@johnhopkins6260]

Brilliant!! (ideas to toy with bigger, heavier (tool box-sized) with alternator... (could be "pre-charged" with electric drill prior to use)

[@esqueue]

Or connect directly to the battery and charge it up that way.....

[@htmagic]

LaserSaber, it is good to see you making videos again. Thank you for showing us this unit. I like the new case for it. Will you offer this as a kit? I'd buy one. The handles are already unavailable.

[@smallmoneysalvia]

How about a flywheel and gear reduction? A drill transmission sounds great, and a flywheel would let you store impulses from cranking. A ratcheting mechanism with a rack and pinion foot pedal would make it easier to get a flywheel up to speed, then you could stomp it hard a couple times and let the flywheel dump its energy into the generator for a while. You could use a clutch mechanism to get it up to speed with no resistance then close the clutch and dump the energy out quickly. Also, bad idea covering the vents with tape, it's not much but they're there to prevent the cap from blowing up if it shorts internally. You probably didn't make it any more likely to explode, but it's much safer to just mount them with some room to vent if one goes tits up.

[@tberry7348]

soupisgdfood I was thinking very similar with the fly wheel only I was thinking add a second alternater put small gears on both and a bigger fly wheel connecting them twice the output with less cranking. Also 10 rechargeable aaa or aa batteries for increased runtime.

[@davey2k12]

tberry7348 ya just killed it with aa batt lol cud switch to bat power this uses caps lol

[@owensdaniels6244]

sir you are going to start a million dollar bussiness with this cause everybody wants one

[@bobanderson7165]

If you put the crank on the top and a on opposite sides you could in a seated position, put the box between your legs and grab a handle and crank easier; especially with a longer crank handle.

[@raisagorbachov]

One of those souped up to start a 7 liter school bus engine would be phenomenal.

[@piotrlenarczyk5803]

Test supercapacitors in knots to Li-Ion batteries packs in absolutely balanced binary tree. It theoretically could give you occasional high-load and higher capacity capabilities. Some driver, and balancer could be necessary.

[@Walkyrjenny]

Instead of a hand crank, perhaps a bicycle-wheel hook-up? With proper gearing, you could get a great many cranks per revolution. For that matter, it occurs to me that you could put the rear-wheel gear directly on the generator shaft, with a 2x4 running to a set of pedals -- you could even replace the pedals with handles, if you want to keep it a /hand/ cranked jobbie.

[@jcknives4162]

I'm guessing that in warm sunlight your adhesive tape might let go of the booster pack... Maybe a support structure inside?

use a low KV brushless motor, say 300-600KV and 3D print a multiplication box of about 1:100 to get about 6000rpm, maybe 1:50 if its too hard, but the harder the more current, just make sure the gears are sturdy enough.

I just purchased a low mileage 2012 Nissan LEAF, I charge it at home with a 220v charger; my wife is a little worried that I should have a back-up power supply.

Carry a cordless drill along with this and eliminate the hand crank and or have the hand crank in a side pouch as an option incase everything else failed. Just chuck up a cordless with keyless chuck and let it spin it up. You then can have the solar also charge cordless drill.

[@jrdirty4797]

There has to be some heat generated by those capacitors. How do they dissipate any heat? Also, you have so many wires soldered together on the Cap Block why not use a wiring terminal strip? Interesting project. One I would take camping and use the solar charge feature to keep it going as well as cranking.

[@meco72104]

You could build one with some sprockets, One on the crank and one on the generator. With like a 6 to 1 teeth ratio connected with a chain. That way for every turn of the crank the generator turns 6 times.

[@electronicsNmore]

Very nice unit. I can't wait to see it in action. :-)

[@darkshadowsx5949]

the "hand crank generator" is a geared brushless motor just find any one with around 10-30 rpm and higher ratings. some companies use the same motor and different gearing so speed doesn't matter as long as you can crank it that much consistently too fast and you wont be able to use its full potential.

[@Русскаярысь-ь5ж]

Hi. Friend! It is a greatest idea between others similar!!!

[@qqube4762]

Experiment with gear ratios. Try something like a 1 to 4 ratio to start out with. For evey 1 turn of the hand crank the motor will turn 4 turns. Use some capacitors of 10000 UF. Just a thought. Lots of luck.

[@oprashanth]

Can you use this to jumpstart a car? Handcranking your car seems most useful if your battery is dead, but you are on the side of the road. I don't want to replace the battery, but if it's dead at a certain moment, a handcrank will be very useful!

They’re stackable, waterproof, come with their own handle, and they provide a little more accessibility for fuse changing or other minor repairs. Maybe even space for a larger and removable crank handle?

[@AnotherCoyote]

Re-posting for justice: Have you seen anyone use a gear train with a bunch of generators and extra caps AND a fly wheel to make a better, truly awesome hand crank or foot crank generator, yet? The kind that can power an electrical appliance like a refrigerator or computer? Any idea if Charles Greenwood (man behind the humancar) used such in the design for his DuetGen? Because that guy can power a car to drive 50 MPH with that set up while rowing the hand crank back and forth, I believe, correct me if I'm wrong.

[@tberry7348]

without the led lamp, light, and crimping tool this project is around $255.49usd, if you get the crimper $276.83. Many of the projects parts are no longer available from the original sellers. Cannot find a similar project box of the same size but slightly smaller ones are running around $12. if the conversion calculator I found is right 4800f = 4,797.648as = 1.33268ah charge. I think I have gotten 4 packs of 1200ah aaa rechargeable batteries from kroger for around $9.99. in theory the cap bank could be charged almost instantly and discharged instantly where the batteries can be speed charged in about two minutes at a cost of damaging the batteries. I have a 15 minute charger that never takes more that 2 minutes to charge the bateries but they're almost hot enough to burn you after and have to be replaced more often than recommended. anyway love the concept but way out of my price range especially when I add a charge/discharge controller and other mods. I don't get why no one uses salvaged tube TV caps for this kind of project.

Could you possibly use a bridge rectifier and make some kind of rack and pinion setup that you slide the rack back and forth that can drive 2-3 motors? Eh idk probably overcomplicating something that already works just fine .
