[sunnyintel]

you shoud try using a 10W wirewound resistor :P uve exceeded the rating on that resistor :P

argh, i know this channel long, and i just saw that i Was'nt subscribed, so i just subscribed

[kimdaviscali]

So much excellent workmanship and construction quality to do what, toss up a metal ring? Such a waste of what appears to be a very well built power supply... by the way, I'm sure you realize the fan would work a lot better if the lid was on...

[kimdaviscali]

The point?

[LUVB6CPPgmodcsscoder]

Is that a MOT?

[bobdavis321]

@LUVB6CPPgmodcsscoder - Yes!

[AsymptoteInverse]

That platter emits some very musical noises. And those capacitors are very impressive.

[ferencproject]

What will happen when you will sit on it and then launch it (while you'll be sitting on it)? :D

[Serostern]

Dude, you should replace the resistor with an inductive ballast.

[AsymptoteInverse]

@Serostern I was thinking the same thing.

[Kawe87]

Harddrive pannels?

[MarcomMrX]

After that video ufo mysteries continue again :D



[DanFrederiksen]

shouldn't you have thicker wires?

[20fireman12]

Can you show how to build that?

[bobdavis321]

@20fireman12 - There are some pages about it on my blog at bobdavis321.blogspot.com

[20fireman12]

@bobdavis321 Thanks!

[MrHerbert1270]

Instead of a vertical system try for a horizontal magnetic launch platform at a target, spring retention, etch etch it would go thru a car!

[cumesoftware]

Is that washer of yours a platter from an hard disk? Just curious! :)

[bobdavis321]

@cumesoftware Yes it is a hard drive platter.

[cumesoftware]

@bobdavis321 Thanks!

[ThrasherContinue]

@bobdavis321 it resonates like one

[SuperUtterChaos]

This is really fascinating! I can't see the video, only hear it. Could you describe how your coil is wound, and how it affects the washer? I'm wondering if it affects the washer's temprature as well, since the pitch of the sound goes up rather than down as it goes up and away? Very interesting!

[jonjoy1999]

@SuperUtterChaos I think that's the low out-of-resonance pitch frequencies reducing, leaving just the resonant frequencies remaining

[Robots4Sale]

you need a gfci so u dont melt something and kill yourself, also you need a top to it so the fan actually pulls air over the capacitors, if you dont have a lid, then the fan is useless

[Microwave89]

Very amazing noise! :)

I really started laughing of that :D

Thank you!

[Biospark88]

They're RED HOT! Get your resistors while they're RED HOT!

[chills2102]

Those are some good size capacitors and lots of em. It would be a shame if you were to connect them all in paralell, at reverse polarity,and happened to have a camera handy..... hint hint.

[Aviator14]

You need a higher wattage resistor

[karkeyes]

okay ready to launch....*car drives by*

[mentalabsence]

Also ENERGY is measured in Joules... POWER is measured in Watts, idiot

[jonjoy1999]

@mentalabsence that's right. insult him for a technicality from your armchair. great job, high five. do you feel like a big boy now? it's rather nice to see that you live up to your username.

[mentalabsence]

@jonjoy1999 I'm sure you do too. You sound like you're full of joy. White sticky joy that's just come out your dads cunt.

[jonjoy1999]

@mentalabsence you have failed. you have lost. have a nice day! :)

[mentalabsence]

You sound like Ned Flanders

[thebigpoopful]

That was very cool to see!

[shortyjk95]

WTF??? how does this work electro magnet?

[BMLarson93]

that resistor looked a little worn out.

[quantumcherrypopper]

Would you sell me one of these? I wanna make an EMP generator. Maybe put it on ebay? Im dead serious... Please get back to me.

[CSpannerz]

Is the back fan actually rotating? Nice build BTW :) Hope you've fixed the smoking issue? :\

[totalrandomcrap]

Hey, can you grab me one of them energy drinks in the blue can on my workbench?

ZAAAP!

[DrTran0007]

LETS GO TO 9000000 VOLTS! BWAHAHAHAHAHAHAHAH. o_O

[Blo0daXe]

Cutman, gutsman! Bring me that railgun!

[JohnDenholm]

Who knew Kermit the frog was into all this stuff.

[pathosbedlam]

Make me a rail gun or STFU. LOL. Just kidding. Interesting build.

[bobdavis321]

@pathosbedlam - I am working on a dual head version to lunch two rapidly. Also working on a soda can launcher. I want to put several of my devices together in one video and try to get on America's got talent......

[pyromohanzed]

u could probably get on more than just that , im sure @bobdavis321 

[iBradleyAllen]

what was the platform used to launch it? just saw what looks like a board; then it pings and it flies up; then the thing that lands sounds like a horseshoe but its a washer?

[josephoo7]

can you say "red hot resistor" one moar time, I love it when you say it.

[freakshowboy9]

dude you must make a coil gun and hook dat shit up!!!!

[TheSunergizer]

To make something practical of this. Make a rail and learn to shoot projectiles.

Future tanks will fire projectiles magnetically. Heck, if you get it small enough, you might make a man portable Rail Gun. Make some big bucks as a weapons designer.

[mgregggphone]

are you using a SCR or something as a switch to switch on the current?

nice build.

op, yup, you did mention a scr at the end of the video

[mgregggphone]

are you using a SCR or something as a switch to switch on the current?

nice build

[kitchenfromhell]

It sounds like the alien spaceships I hear in my dreams.

[Cardgames4children]

I like the launch noise it makes PLOOOONNNGGGGGGG!!!!!!!!!!!

[lyrison]

Hot ceramic resistor + cold rain = shattered mess! :)

[Mofoe2001]

Can it run crysis?

[samoged]

what happens if it hits uranus?

[BrandonFurtwangler]

you could calculate how high they reached based on the time they're in the air.

[sonnytiger]

This is really cool, I have a couple of questions though, i don't see a rectifier anywhere, or do you need one for those capacitors? Also are you just using an electromagnet to launch the hard drive platter?

[bobdavis321]

@sonnytiger There is arectifier there, from a microwave oven. The electromagnet is a flat coil of wire.

[dasraiser]

so if you put another device like this on top but upside down, with a direction trap for that platter, would it shoot out like a Frisbee?

[myryonspoof]

thumbs up if you got here from photonic induction's vids

[bobmcgee7]

now just have it shoot a bolt down some kind of barrel and woot u have a gun

[ozzyDattic23]

I can just imagine some one walking by mining their own business and getting hit in the head by the washer......Jackass

[ozzyDattic23]

I came from watching Back to the Future Flux Capacitor to this shit.... Am Confused

[kittyfanatic1980]

if the resistors are glowing and smoking obviously you messed up on that section. you need to switch the values or heatsink those bad boys. its an awesome project otherwise i love how that washer flys:)

[Alexander9170]

I NEED such capacitors :D

[Minifig666]

Are those HDD platters?

[sciman001]

what case?

[calvinthedestroyer]

What is actually launching the washer?  I'll I see is a block of wood

[bobdavis321]

@calvinthedestroyer - There is a flat coil of 14 gauge enameled wire, sized to match the washer / hard drive platter

[calvinthedestroyer]

@bobdavis321 So... data recover is out of the question? :) wouldn't that attract the washer instead of launching it? Also, Have you ever worked with MRI coils?

[rfry]

Do capacitors really "get more used to it"?

[isilder]

@rfry Uh, yeah the di-electrics are not perfect. The dielectric property is related to the molecular polarity ... Considering the best dielectrics are really thick oil like substances... When they are charged the molecules are polarised better..



[rfry]

@isilder interesting

[roofy2k]

if u get electrocuted can i have it?

[bobdavis321]

@roofy2k - Sure!

[ApolloWasReal]

Why not use a bank of light bulbs as your ballast resistor, instead of frying that poor little wirewound that's obviously waaaaay underrated? When the lights dim, you're ready to fire.

[jayynecobb]

You need a cooling fan...because the missing case top isnt good enough? heh.

Use a large inductor instead of your resistor. You'll be pleasantly surprised :)

[Llamarama100]

What a fantastic sound! :)

[RChero1010]

Correct me if I'm wrong, but couldn't you put the resistor in front of the fan?

[emil3277]

awwwww.... thought you were gonna blow up the capacitors...

[TheJefedesapuka]

5:53 wonderful place

[jhbonarius]

I wouldn't place these capacitors in series and charge them to (nearly) the double maximum voltage rating. Because of the difference in capacitance due to the limited accuracy, the unequal voltage division can lead to over-voltage on the caps. Which could lead to a dangerous explosion!

[jayynecobb]

@jhbonarius not true. as soon as the lowest rated cap hits OV, it will break down and may explode. Your way reduces them to (1) divided by (1/c1+1/c2+1c3...+1c8) and it wouldnt have any launch power.

[ApolloWasReal]

@jhbonarius You can safely stack capacitors in series if you use dividing resistors across each one to equalize the voltages.

[axel1973w]

Wouldnt it makes more sense to improve the cables and contacts instead of gaining even more voltage? i mean... more voltage makes the contact and cabeling resistance not any better.

[jayynecobb]

@axel1973w Not going to get a voltage drop from that length of wire. Wire size in NEC code is set for overcurrent safety. OC devices must be incorporated in everything but fire pump systems (and little experiments like this lol)

[h3xyournightmare]

put that resistor on a radiator with a fan ;)

[bigjobbruce]

3:42 love that sound

[locobeis]

he has the same voice of peter lindemann, hi pete!

[18Dizz]

Is there a practical use for this thing, or did you just build it to shoot washers into the sky?? I'm no electrical pro, but either I'm missing something, or you live in a VERY boring town!! Great job on the build, nonetheless...

[wordreet]

@18Dizz You may as well ask why did Bugatti build the Veyron? It merely cost them money, but they were just showing off. ;-)

[bobdavis321]

@18Dizz - Its also boring to drive cars in circles....NASCAR...

[18Dizz]

@bobdavis321 Agreed!! I'm not a fan of NASCAR myself, however I AM recently starting to learn more about capacitors and resistors as part of my introduction to the hobby of electronics to be honest... (partly due to watching this video!!!) Your video has given me inspiration to want to build (unrelated) projects involving capacitors on a much smaller scale. So thank you!!! And again, great job!!!...

[MyWillyboi]

@bobdavis321 There are road courses dingle sperm

[videoproducer100]

@bobdavis321 - Nascar rocks, and not all tracks are ovals (Watkins Glen, Infineon, etc).

This is just pointless. ooh I can shoot a washer into the sky, Big deal.

[io504]

@videoproducer100 To be fair, I don't think many people could build something as impressive as this. No disrespect intended.

[MyWillyboi]

@18Dizz You sir are a dumbass! This is the sme thing as a coil gun the navy developed a badass version of this that will soon replace the munnition cannons

[18Dizz]

@MyWillyboi

Thanks tips!!... And you, sir, are an illiterate moron with absolutely nothing better to do with the 'apparently ample' time on your hands... I'm not into Naval practices, nor am I the least bit interested in coil guns, so how about you pull out your crayons & colouring book the next time you feel the sudden urge to write down any more of your lackluster comments... Does that make sense "dingle sperm"??

[Solarenemy1]

@18Dizz

Oh ye of little vision. Take this circuit, Put charger in a backpack with battery power instead of AC. Place a non metallic shaft in the center of the coil. Then using small aluminum rings that just fit over the shaft as ammo. You now have yourself a magnetic ring launching gun that could be used in many ways. Aluminum creates it's own magmatic field that opposes the magnetic field of the coil. So in theory this inductance launcher is more efficient than a reluctance launcher aka CG.

[iRiselyTech]

@18Dizz This thing threw that washer higher than you could. STFU

[Transane]

that is hands down the most dangerous way I could think of to shoot a washer.

[offmeds2nite]

joules are a unit of energy, not power. You should alter your description to reflect that.

[offmeds2nite]

joules are a unit of energy, not power.

[ConnorXV]

watch ' how to make a 400v charging circuit ' to learn how to make a circuit from scratch capable of charging photo flash capacitors, you need little electronics knowledge and you only need four components.

[bobdavis321]

@ConnorXV - Did you use a bridge rectifier and 2 capacitors? I used a voltage multiplier at first in my older videos then as I got up above 1 KV I switched to a microwave oven transformer.

[ConnorXV]

@bobdavis321 it just needs a four components found in a photo flash circuit, the mini step up transformer, the rectifier diode, the 220 ohm resistor and npn transistor.

[ConnorXV]

@bobdavis321 i've searched all over the web and found nothing on how to make your own actual charger circuit for a 300-400v capacitor bank so i found out how to make one by my own means of examinating the circuits.

[d1oftwins]

Epic sound is epic!

[MrPaulo1471]

@bobdaves321 what the resistor value?

[jk1567]

where did you get that???

[bobdavis321]

@jk1567 - Built it myself.

[Landotter1]

Nice repulsion coil... All you need is a higher wattage resistor. What is the voltage rating on yuour caps? You could also use an SCR on the input to the transformer, to control the charge rate. Cool project...

[Philipians121]

Question: Why not make a rail gun type system to launch the washers. It seems you have plenty enough power.

[bobdavis321]

@Philipians121 - I might just do that I have two huge 15 uF 5 KV caps to play with.....

[Philipians121]

@bobdavis321 That would be awesome!!! keep up the good work and the faith!

[ford2high]

@bobdavis321 how do you make this cause it would be cool to make one with my son

[bobdavis321]

@ford2high - Check my blog at bobdavis321.blogspot.com

[HoneycombAgent]

Are these charged in a series or parallel?

[WildoTheRubberFist]

I could see this applied to model rockets. Would be a fun project.

[chickenpoper]

Put two or more resistors in parallel as in one end of both resistors connect to one lead and the other two ends connect to the other lead. This increases the amount of tolerance that can pass through the resistors making the heating of the resistors decrease! I'm 13 by the way

[Landotter1]

@chickenpoper Sounds like you have the concept here but your wording is a bit off. Good job though. When putting 2 resistors in parallel remember, if the 2 are equal value, the parallel value will be half. 2, 10 ohm resistors will be 5 ohms but the power rating will be double because they share the total current. 5, 10 ohm resistors will = 2 ohms but 5X power rating. Unequal resistors will be somewhat less than the least value resistor. I forget the formula but look on line.

[andreweasygale]

Great! Now all my credit cards have been erased!!

[Envergure]

Why does it need a charging resistor?

[bobdavis321]

@Envergure - it prevents damage to the capacitors on charging and protects the diodes on discharge. There is a reverse EMF from the coil that destroys unprotected diodes. My defibrillator capacitor experiments resulted in a fried power supply because of the lack of a current limiting resistor.

[MrTpengineer]

There are actual resistors withe heatsinks, I don't remember where i've seen them but I belive there for high power equipment, you should try to look it up some time. (in case you need to replace resistors :)

[BingoSunNoon]

Chucking a washer is pretty cool. But I want to see the dryer flying thru the air.

[bobdavis321]

@BingoSunNoon - I could use a new drier....

[benposeno]

how does the washer launching part launch washers

[bobdavis321]

@benposeno - Electromagnetic repulsion. This device applies 900 volts to a flat coil that then repels an aluminum washer.

[karuoun]

Have you tried anchoring the 'washer' to the launching unit?

[FrigginSmift]

That flying washer sounds super creepy! 0_o

[only1sn1not1taken]

Why don't you just do the math to calculate it's height? There's enough info on the video to figure it out if you also determine the horizontal distance it traveled.

[MultiPoseur]

why

[MrPaulrevere]

I think you need a better charging resistor, lol

[bobdavis321]

@vampyre069 - Thanks!

[TWOLF365]

All that crap to chuck a washer into the air?!?!?! What a waste of time and money. Just give me the washer and the money it costs to make one of those things and I will toss the washer in the air for you...if thats what you want to see is a flying washer!

[bobdavis321]

@TWOLF365 - I am working on flying saucers, but I take it one step at a time.....

[TWOLF365]

@bobdavis321 lol Well good luck with that. If you need a test pilot don't ask me. There is something about jules that just doesn't sound good in a bulk amount pushing upward under my butt....lol

[bobdavis321]

@TWOLF365 - Its a combination of special coils and the ionic spinner as a source of ions the coils then accelerate them and produce lift. So far no success......

[kevmanev]

@TWOLF365 complete retard, you do not understand science.

[Redrobottyler]

If you don't already have one, could you kindly make a tutorial on how to craft one of these lovely machines? I would love to build one of my own and yours look like the perfect size for what I would like. Thanks :D

[bobdavis321]

@Redrobottyler - Check out my blog at bobdavis321 dot blogspot dot com

[Redrobottyler]

@bobdavis321 Thanks!

[nickntab]

so what is this for???

[Psychlist1972]

That fan's not really doing you any good, is it? It's open on both sides, so presumably it's just passing air right in front of itself.

Very cool, btw :)

[bobdavis321]

@Psychlist1972 - it came with the cabinet....

[AsylumET]

@bobdavis321 it coming with the cabinet means nothing. You have no top on it so the fan cannot perform it's job of cooling anything other than maybe the backside of the one capacitor it is directed at. If you are noticing the resistor heat up to red hot maybe you should direct a fan at it. Also did anyone find it odd that @ around 2:38 you see the washer never leave the launch pad or am I missing something here?

[tvoice1]

Love that sound it makes in the air

[locouk]

So what would happen if you sat on it?

[bobdavis321]

@locouk - You would get a really sore but! It has a lot of force behind it!

[sargeantneo1]

How does it work? the launching that is

[bobdavis321]

@sargeantneo1 - Electromagnet repulsion. Aluminum repels a magnetic field.

[theewelder]

u video quality is awful in fullscreen,its splits...?

[bobdavis321]

@theewelder - That video was shot a long time ago before I had high quality cameras.

[nxmoparmatt84]

i wanna see you launch at 1.21 jiggawatts

[TheClown316]

@DragonWagon6 mother freaking lamo come on you know everything about audio answer the question you damn self  and you dont need a cap for your wal mart system

[2954lndr]

essa potencia pode matar alguem!

[edit1754]

Joules = Energy (kg^2 m^2 / s^2)

Watts = Power (kg^2 m^2 / s^3)

so you can't have "about 3,700 Joules of power."

[clemstevenson]

one-point-twenty-one gigawatts!!!!!!!!!

[bobdavis321]

I am lost? Are the batteries in series? 

[StoshTech]

@DragonWagon6 if you have a weaker or older alternator, i advise using a capacitor. people say they dont do anything but they really really do. i install car audio equipment, in my experience, capacitors can make the difference between a sound system that causes your car to run rough or high idle, have lights dim, etc, or having a perfectly balanced system. you just gotta know what capacitance you need.

[McdonaldSpecial]

if you test it more than once, its not a test fire, you're just playing around.

[thisisobvious]

damn.. thought I was going to get to see a bad ass explosion.

[jinx748]

Is that resister in between the cap bank and the transformer?

[bobdavis321]

@jinx748 Yes-It limits the charging current

[jinx748]

@bobdavis321 Is there a better type of resistor that would have lasted longer?

I guess I should ask instead, did you fix the problem of the resistor frying like that?

[bobdavis321]

@jinx748 - Yes it was fixed in my later videos

[TutorialsByKevin]

CONNECT AN TV ON IT:D:D:D

[Dividedhead]

Nice... I was thinking coil gun. Then saw one of your other answers...can crusher sounds interesting too? Gonna look for them now.

Pity your battery ran out too... It looked like you were not too far off heading for a Sideshow Bob with that rake!!! :-)

[LordLab]

3700 Joules of power = 1.0278watt

sounds very low, are you sure this is 3700 Joules ?

3600000 Joules = 1 kWh

[hardstyle905]

@LordLab Oh boy. 3700 J in high voltage capacitors is not low. Released in a matter of milliseconds doesn't make it that low either. This can produce a surge in the Megawatt range.

7.62x51mm ammunition have a muzzle energy of 3500 J. Rethink your words....

[bobdavis321]

@DragonWagon6 Car audio capacitor? They help reduce noise from the Alternator, etc.

[pyronathanpyro]

u trana put a nice hole or dint in some1s heed power it up more lol

[giorulesallofu]

@bobdavis321 How are you getting 900v if your microwave transformer outputs 2kv ac which has like 3kv peaks?
