First test with 4.8KJ xenon flash lamp (Speedotron 4803 strobe light)--- make money online

This video shows my entry into the world of high-intensity flash tubes. I was inspired by the work done by the famous Doc Edgerton who built a strobe system for nighttime aerial photography. I've heard the biggest system he built was somewhere between 50 and 75 KJ per flash -- the power needed to illuminate the ground from 1000 feet in the air!

The system in this video is a Speedotron 4803, which delivers up to 4800J per flash. Photographers use the units watt-seconds (Ws) to describe the energy in each flash, which are the same as Joules. I plan to add capacitance to the bank in order to increase the total discharge power, but the voltage may also need to be adjusted since the higher power flashes also tend to require higher voltages. I'm also planning to try different xenon flash tubes, which are capable of more intense flashes.

yeah hey everyone check out this new bit

of kid I just picked up this is a flash

unit for professional photographers and

this is one of the most powerful that's

ever been made apparently this is a

speedo Tron 4803 and basically inside

that box there's a power supply and a

lot of capacitors and then the cable

runs out to the flash unit and check out

the size of that flash - yikes

so the thing has the capability of

dumping 4800 joules in a single flash

through that flash tune and I've been

interested in really really powerful

flash lamps for a while but someone

recently posted a comment about dr.

edgerton's aerial photography at night

so there's a flash tube a built-in I

think World War two and put on a plane

then flew the plane around and actually

took flash photography from the air so I

don't know if I'm going to get that high

I think they were in the region of about

fifty to seventy-five kilojoules per

flash and this is 4.8 kilojoules so it's

about an order of magnitude away that my

plan is to open up this box and add some

capacitors and kind of play with it and

see how much power we can really get so

all right let's let's let's see what it

looks like stock I'm kind of going to

get behind the flash lamp so that I

don't have the flash light exposed to

the camera array and I'm going to press

the test button here this is a full 48

hundred watt second flash so I mean

clearly I I can see on the back of the

camera that it's probably just a white

frame but nonetheless it is bright we'll

do some demonstrations later showing how

much heat actually comes off of it but

if you put like a black piece of plastic

in front of that flash unit and pulse it

actually melts the plastic a little bit

so this unit has a top and a bottom half

and the bottom half had wood screws

holding it to something and the top half

had machine screws and since I've

already got this thing open I just put

it back together for the camera don't

bother with the wood screws if you want

to take this apart just take off the

machine screws that are in the top

section and then you can lift this off

there's enough cabling inside so you can

just put this down and not have to

disconnect the cables while you're

balancing the lid and stuff alright so

let's take a look at this okay we've got

capacitors in the bottom and circuitry

in the top and the capacitors are all

nicely bused together with those

galvanized bus bars and quite a bit of

circuitry and here is a fair bit more

than I was expecting

so I just charged the caps and then tip

this over to kind of get the caps out a

little bit and as you can see they're

custom labelled caps they're even

labeled speed of Tron and from the model

number 2000 - 450 I'm pretty certain

that would be two thousand microfarads

at 450 volts and if you do the math each

cap has a storage of about 200 - joules

one-half CV squared and there's 24 of

these caps in here so that's 4860 joules

so that actually works out just about

right so that that makes sense the

charging scheme is a little bit

interesting let me let me show you the

circuit in the inside the front panel of

this machine has different plugs for

different power settings and so the way

that you actually direct a more-or-less

power to your strobe is just to unplug

it and plug it into a different spot on

the front and there are spots for 800

1600 2400 and then if you combine the

last one it's 4800 for the for the

combined set so this a bus bar

arrangement sort of makes sense it looks

like 1800 1600 and you put these

together it's 2400 and then this is

another 2400 and so you get 48 for the

whole pack so you can see all the

capacitor banks connected to that

circuit board there and I see a whole

bunch of diodes in there which

originally I thought was my than a

voltage doubler ladder but no I think

that's probably just for charging so the

thing can charge individual cap banks

without worrying about the voltage from

all of them also notice those two really

large resistors in there that might be a

way that they reduce the inrush current

when the cap bank starts charging hey I

got this wrong so actually on this half

of the box these caps are all negative

common and this half is all positive

common which makes sentence so that this

thing probably does charge the caps at

450 volts and then discharges then in

series at 900 so that also makes sense

why this this section here would be 1600

and this would be another 800 and that

would give you 24 so they always want to

have two halves of the box top and

bottom to get the voltage doubling so

you can't have

3200 because that combination is not

possible it has to be 816 or 24 or 48

let me show you how much power this

flash has I have a little piece of

plastic garbage bag I've measured the

thickness but it's it's awfully thin you

can almost see light through it so I'm

going to put this under the flash lamp

and look away from it while I'm flashing

while I press the button so we have the

full 4,800 going into it

and the the plastic sort of melts onto

the dust that was on the table there and

shrinks quite a bit because it was sort

of instantly melted and then it read a

summary solidifies very quickly because

it's so thin start another shot well

it's still hot the plastic is quite soft

and stretchy here's a piece of very dark

paper it's fairly heavy like magazine

weight paper and I'll put a black side

up

doesn't catch on fire of it it's kind of

bubbly and crackly on if you can see

that sort of nicely texture let's try a

couple of shots on it I also put the

charger into rapid-cycle mode so it's

pulling quite a bit more current to

recharge the cap bank and it recharges

in about four seconds now

it's kind of oh actually wait a minute

me this be cool it's kind of

delaminating it feels like there's two

layers to this paper let's try this

piece of coroplast this is a really

lightweight plastic that's very

absorption of light

it's nice and warm I mean it's hard to

appreciate how much energy this thing is

dumping in such a short amount of time

it it basically feels like this thing

was laying out in the Sun all day we'll

try a couple shots kind of in a row

maybe you can see it's kind of curved

now since the top section is heated up

so much more than the bottom it causes

the plastic to expand and then the piece

bends a little bit kind of neat about

some really fine steel wool this is I

think for OTT

a little nice trail of smoke anyway so

it's not quite as powerful as I

originally expected but that's kind of

the whole point of this project my

ultimate plan here is to replace some or

all the capacitors and in the bank here

and just use their charging and firing

circuit and maybe also change the lamp

I've got a line on some even higher

power xenon strobes

so hopefully we'll be getting up close

to the 10 kilowatt or 10 kilojoule range

pretty soon also a better reflector to

focus the energy to a smaller spot

there's also a lot of other really cool

things that you can do with this Ruby

laser rods and YAG laser rods and those

would be really cool experiment

especially since the flash tubes already

in a helix alright see you next time byeTop Paid Keyword :  earn cash online, google make money from home, earn money online without investment by clicking ads, free earn money website, online money making jobs, earn money online without investment by typing, online work for money, best online earning sites, make money online with google, online earning websites, money making websites, online earning websites for students, invest online and earn money, best online money making, online money income, view ads and earn money without investment, earn money online by clicking, online money income site, money earning sites, online earning sites, best website to earn money, free money earning sites, money earning websites, get money online, online earning tips, online earning without investment, earn money online without investment for students, earn money by clicking ads, earn money online without investment, online earn money website, online jobs to earn money, best online income site, top 10 online money earning sites, easy income online, easy online earning, earn money online from home, make money online legit, earn money online free fast and easy
