GB: Australia Ultra-Capacitor *Collecting Money*

Re: GB: Australia Ultra-Capacitor

Yup^^ That's why I'm going for 5 in series and possibly another 5 in parallel with the first 5

Pretty much

The more you have, the more fun you can have

Fiddy, I want to see your 6 caps in action Also, wouldn't it be better to run them in parallel? The voltage will decrease therefor dropping the risk of electric shock.

You really dont want to get shocked with these... not to mention 6... That would be lethal.

as Things said, 15V wont do shit to you, your skin is a decent insulator, ever try putting your hands across a car battery!

Saying that i was doing up the positive battery terminal on my car with a spanner, and leaning ontop of my alloy air-box (which is grounded) with my other hand which had a decent cut on it, i was getting tingling/burning sensation through the cut on my hand!

Ive been playing with electricity for a while, my old tafe had 3 phase 41.5V (10x smaller than actual mains). 41.5VAC 2 phase across a ring on my finger made my finger tingle and move involuntary!

Things said:

Nope, 6 of them is only 15V. You won't even feel it. You're going to need to approach close to 50V before you'll start feeling anything, and that's a hell of a lot of supercaps.

Putting them in series means you have a higher voltage, but the same current handling. Higher voltage means it can force more current through a higher resistance load.

That is spot on!

Also id like to mention that the capacitance drops in series, it was taught to me that in series you are effectively increasing the air gap between the 2 plates in the capacitor, decreasing its capacitance.

Formula for series

C total = 1/ (1/C1 + 1/C2 + 1/C3) etc

And that in series you are effectively increasing the plates surface so the capacitance increases.

Formula for parallel

C total = C1+C2+C3 etc

That will be a monster

Re: GB: Australia Ultra-Capacitor

yeh, I know that 12 volts wont do anything to you but theres always the risk of accidentaly spiking yourself with the wires or touching them on a wound. Still, thats like 0.001%.

Adrian, put me down for 4

Re: GB: Australia Ultra-Capacitor

hehe yup, only dangers are burns at this stage
good to see your jumping on the band wagon!

a good thing i saw was using these for a coil gun or aka a rail gun!
i may look into it as i work with induction coils at work

Re: GB: Australia Ultra-Capacitor

Wish I could go in for more of these, looks like I can only take 1 for now. Dead broke at the moment

Re: GB: Australia Ultra-Capacitor

Use induction to melt metal now do you?

Things, I can send $10 your way if you want so you can pick up an extra, maybe in the next few days

Can I have $10 too???

I'll show my moobs.

Re: GB: Australia Ultra-Capacitor

Just for putting up that picture i'm gonna have to say no

Maybe another time when that picture gets out of my head.

Re: GB: Australia Ultra-Capacitor

Put me down for 4 Adrian.

Thanks

yup thats what we do in steel mill

capacitor fund for Things anyone? (cause no Aussie shall go without!)

Re: GB: Australia Ultra-Capacitor

I'l put in 10 bucks, How much you in for Mitch?

he deserves it for his awesome laser harp.

Re: GB: Australia Ultra-Capacitor

ill match what you put in!

Re: GB: Australia Ultra-Capacitor

Feel the love ...

Also, cheers for that image TJ, very effective at diminishing my appetite, although I swear I've seen that image before, you must have quite an online presence

Re: GB: Australia Ultra-Capacitor

Yay for things! I'll chip in whatever other people chip in for him. $10? =D

Re: GB: Australia Ultra-Capacitor

Wow, things, you've got $30 so far!

LaZeRz-$10
Fiddy-$10
azzman372-$10

Re: GB: Australia Ultra-Capacitor

Wow, that's extremely generous of everyone

Hmm, remind me if I ever travel to Sydney to meet up with all of you. Surely there is enough of you for a LEM by now??
