6 under water LED destructive tests

[nealshireman]

Wow! that's really powerful!

[poiiihy]

what happeed to your camera after the first explosion? it makes a noise.

Hahaha.

I like your videos. Container blown up :D

[joshuax989898]

well thats what happens when a fuse blows

[joshuax989898]

thats what i call a blown fuse

[SayrexZ]

led 4 made bubulz :D

[CpTnlAw]

I think it's not the current only... Current flowing must be generating hydrogen and oxygen, while the voltage is sufficient to jump the gap , and ignite the gaseous mixture. Hydrogen + oxygen detonates and creates a shockwave destroying your container...

[jk037]

It sounded - and looked - like you injected brief high voltage pulses into your test subjects. How long was each pulse, and what were the voltage increments?

[RODALCO2007]

@jk037 Voltage pulse was about 1 second. increments steps of 100 Volts at the time. most shots were at around 1.5 kV and over

[MegaDrLemon]

What the fuck was up with LED 2?!

[redsquirrelftw]

lol these videos are fun. They do silly pointless but fun experiments. So we don't have to!

[juicyghu]

curious what effect this has on the water structure..was the same water used with differnt LEDs?

[RODALCO2007]

@juicyghu Same water or it was topped up after a minor spill except when the container blew up.

[RODALCO2007]

19000

[hilers72652]

why does it blow up twice? (sometimes 3 times)

[RODALCO2007]

@hilers72652 That is the high voltage spark jumping across the gap of the led's terminals.

[OnnomonnomonnO]

17  hunrdet volts...........oops....:DD

[IVOilDivo01Iras01]

Hi...I am from Italy...i do not understand...What is the MAXIMUM Voltage did u applied??...

And what kind of voltage is it? ---> Alternate Current or Direct Current?

[lonesoldier33]

I want to see this kind of thing in slow motion! :D

[intheshitter]

Should put an LED in an icecube and do this :D

[HoneycombAgent]

When you divide stuff by zero, etc. etc...

[superjojo555]

you are crazy man!

[Wabbit0789]

just wonder when he going the electricute himself :o

[Moroboi]

thats a freagin thick ass wire for an led. no wonder it blew up.

[TheGuffy1990]

second one was best!! it blew up the container!!! XD

[mrmattandmrchay]

cool, like the ending!

[griphonus98]

why do people dislike this?? they are really idiots- why can anybody dislike a light especially if its underwater! Funny Idıots :D

[RODALCO2007]

@griphonus98 Some people have nothing better to do than winge.

5 leds were rejects out of old equipment, the blue led was new and only costed about 10 cents.

[YTBYlover]

you camera ok? It starts to make an odd noise after the first one.

[RODALCO2007]

@YTBYlover I got water in the microphone

[JDTV1995]

that first one was epic... it was smoking underwater!!

[thebobvideosinc]

that last one was tough.

[HDXFH]

what type of power supply were you using

[RODALCO2007]

@HDXFH A variable DC supply to be used for cable faults.

in steps of 100 Volts up to 4 kV at about 100 Amps discharge.

[dtvjho]

Wonderful things happen with a toy train transformer (12VAC). Connect a non-LED diode like a 1N34, hmmm ramp up to 120mph (full speed) diode lit up orange for a few seconds (a LED!) then blackens and smokes. Green plastic cylinder capacitors, interesting, few secs, bubbles at the top then vents... 3-legged transistors no fun, 2N2222 just popped its top off in an instant. Resistors, just smokers. Electrolytics were fun, vented good.

[RODALCO2007]

@dtvjho Cool !! Please make some video's next time so we can all enjoy the action.

A lot of electronics are fun and if not over volted too much they last longer and smoke longer as well.

[dtvjho]

@RODALCO2007 - Interesting idea :-) I still have that train transformer, a digital camera that can do videos, and plenty of old caps (but not the green ones). I've got a lemon Panasonic 50" plasma TV with bad caps on its power board, so I'll get some extra parts when I order, need to get some regular diodes and light them up ;-)

[RODALCO2007]

@dtvjho Splendid !

even the old dodgy TV caps will blow out nicely when connected to the 240 Volts mains.

[dtvjho]

Just thought of this - check out this video for some 600VDC action: youtube.com/watch?v=nawukWL3PO­Y

I grew up in Philly. A subway-surface trolley is having problems getting uphill with ice on the wire.

[Invisibrah]

It's a good thing I don't have any electronics to play with, or else I would probably explode an LED and hurt myself, because I do not understand electronics.

[RODALCO2007]

@Invisibrah A LED can even explode from a 9 Volts battery when no series resistor is inserted.

It is often a good idea to use safety goggles during experiments, especially when testing.

[mike4ty4]

@RODALCO2007 It'd be interesting to see a videotape of that. 9V blowing LED :)



[SSJStrongBad]

@RODALCO2007 Ah yes. I found that out by accident...

[RootbrianRockzAgain]

THAT was awesome!

[muskakas]

Keep doing that and one day you'll be walking around with an eye patch.

[MultiGangstershit]

wow gestoord!!!!!!!

[The3Dimension]

what's the number of volt used?

[RODALCO2007]

@The3Dimension Varied between 500 Volts and 3 kV DC.

[Berryice1]

holy...thats a lot power!!



[tool4lyfe2]

LMAO 1:26

Guy "900 Volts"

LED "fuuuuuuuuuuuuuu POP"

[vanjastanic]

am i crazy or i see smoke underwater?!

[RODALCO2007]

@vanjastanic Correct ! the led under stress oozes out some smoke, probably the epoxy deteriorating under the High Voltage surge.

[charmio]

@RODALCO2007 actually it's not smoke, it's hydrogen and oxygen! it's called electrolysis which is the decomposition of water into oxygen and hydrogen gas due to an electric current being passed through the water, the equations is 2 H2O(l) → 2 H2(g) + O2(g).

[locouk]

@vanjastanic My guess would be that the high voltage is splitting the water into hydrogen and oxygen. The bubbles are reall small so appear as smoke.

[MEGAMITSIMAN]

How could you blow up one of those nice blue LEDs haha man what a waste

[remyronko]

Looks like it farted at 2:19! Great video...

[bentboybbz]

at 0:16 the explosion messes up ur camera's mic...and what is the clunk clunk everytime he hits the switch??? 5* if you reply!!! and lol at "whoops"

[RODALCO2007]

That is the surge generator ( Thumper ) discharging the high voltage capacitors into the LED under test.

You are correct some water came into the mike.

[Pudersepp]

Why does it explode? The junction sure gets destroyed before 1kV...

[RODALCO2007]

The heat of the expanding LED die, when the current surge flows through the LED makes the plastic case expand rapidly and hence blow apart.

[banaanaboy01]

Oh god im subscribing ! :D!!!

[mrmattandmrchay]

Now that was cool. I'm subscribing!!

[TheLaurencekid]

did you know that if you get a spring submerge it and charge with 125 volts it will boil the water i did it once and made a kettel out of it make sure it is fairly long e.g one from an old hoover the brush spring from the motor trust me it ammmazing :D

[RODALCO2007]

I have done that, see my filament clips

[DragonFlyback256]

Did the camera get water at 0:16? Went really noisy after that. Btw, did any of the LED's smell like hydrochloric acid? Few years ago i zapped a small red LED with my flyback HV and the smell was terrible, made me open the window instantly.

[RODALCO2007]

Very possible. never crossed my mind actually, the noise becomes even worse at 0:51

[RODALCO2007]

Tests were done outside, not noticed any HCL smell

[a380rockerfan]

LED 5 is meh fav. emo pie is awesome!

[Dean129012]

i made an led blow up like that with 12 volts, why the high voltage?

[RODALCO2007]

Just see if it created a different effect.

I had the cable fault surge generator at home over the weekend.

As you already proved, LED's do blow up at 12 Volts and excessive current.

[gixxer989]

so small and so destructive

[cheetawolf]

lol at 0:17

[Coolkeys2009]

What type of power supply are you using?

[RODALCO2007]

a Baua portable surge generator.

Normally used for low voltage cable faults.

[RODALCO2007]

The LED died already at the beginning. The 1.7 kV was basically the flashover voltage between the terminals of the LED.

[Mosfet510]

I like the one that raised the container, and the last one put up a fight to 1.7kv, not bad for an led!
