GB: Australia Ultra-Capacitor *Collecting Money*

[Fiddy]

So here it is.....The monster
And yes those are 95mm2 copper cables!

what g wire is that

 

[Fiddy]

what g wire is that

its between 0000 Gauge (107mm2) and 000 Gauge (84mm2)

 

[Fiddy]

Decided 95mm2 is way to big, it ways the system down and isn't flexible enough...

any whom, heres a nice video i made this evening

 

[LaZeRz]

+1 bro! thats freakin' awesome!

 

[Fiddy]

haha thought you'd like that

it blew chunks out of the speaker and caught on fire!

Id love to see what the 12 caps did together

 

[LaZeRz]

12 caps you say? I think we have another pyro here

Don't bother bringing the fireworks out, Fiddy has his caps

 

[bobhaha]

Over charge the caps? :evil:

lulz

Over charge the caps? :evil:

i think it may go boom then!
the protection circuit ontop of the cap has overvoltage protection and discharges the cap until its no longer overcharged.

 

[Fiddy]

MAKE THAT CAPACITORS INBOUND!

 

[bobhaha]

Boo ya! Can't wait to get these!

 

[LaZeRz]

Me neither!

I might take some high-speed pics when I get my new DSLR in

Speaking of high-speed pics, did you see the new canon 1d x? 14fps 18Mpx jpegs or 12 fps raw! Its insane. Just a few more fps and you can take a video almost. (video being about 24fps)

Just thought I would let you guys know.... I was playing around with my bench power supply, patiently waiting for my caps to come in. Any way I found a pretty cool phenomenon.

Take about a 1cm piece of lead (graphite) from inside a pencil and put power through it. I dumped 5A through it and it slowly heated up to white hot. Next I dropped the current in my case down to ~4.5A @3V till it was not climbing in heat anymore and kinda stayed stable.

Left it here for maybe 30 seconds or so... then turned the PSU off. I noticed as it cooled down you could see an oxide layer form around the lead! How COOL!!

But wait... there's more!

I then began pumping 5A through the lead again and saw massive amounts of sparks flying off this lead (which was not hot at the time). I was like WTF? So I hooked the lead up to the negative terminal and manually moved the positive terminal over the oxide layer of the lead.... and BAMMM! Magnificent amounts of sparks and light!

Apparently the oxide layer reacts with aluminum when hot and basically vaproises!

Check out the carnage...

 

[Fiddy]

nice work!

how much current can your power supply flow 5 or 10A?
how thick are your leads on it? cause if you use those tiny alligator clip leads you will be dropping significant amounts of voltage and current across them when charging the caps!
