You can really see the spark of creativity with this idea
Seems a bit short sighted to me.
Certainly won’t have any resisrance
I’m pretty amped about it!
Great Scott! This meme has summoned the Super Dads!
Well it does have potential
Your current optimism is well founded.
What happens next will SHOCK you
shocking dicovery
And quite current
Hot!
this one truly does spark joy…
Is there a just rolled into the shop on Lemmy yet?
I think the handle’s a little short
The maker is probably not aware of the current battery sizes
He might be schocked by a batteries potential
While making such devices, one should be grounded to reality to avoid making such mistakes
We don’t know. There is no banana for scale.
Banana plugs for scale
The three types of circuit:
- short circuit
- long circuit
- banana circuit
Quick hand warmer.
And warmer!
I once made a deadplug, I was kinda distracted and ended up with a cable with two male plugs. Hangs on my shop wall as memento for “focus on what you’re doing” or something.
Reminds me of this.
It’s a suicide cord. Works great for generators
In short, this is a battery handle.
It will unleash the battery’s potential
Might be terminal though
Perhaps, but I think we’ll see a high level of resistance.
That might be a hot take.
Are you positive? It’s a negative over here
Correct, horse!
Battery staple.
Yes yes fun fun. In real life, I have some pretty huge batteries and there is a handle on each but the handle is a non-conductive rope.
Considering that a 12V battery has an internal resistance of 20 milliohms, the potential current through this thing would be approximately 600A.
It might be too hot to handle (pun intended)
You can also get that from just the label. The CCA rating (cold cranking amps) is the max current that specific battery can supply in short bursts. 600 CCA is pretty typical, but I’ve seen up to 900 in the batteries I ship.
Is it really 600 amps? That seems rather high. I do know that the one time I shocked myself on a car battery, it rocked my world much more than getting shocked by a 110v outlet.
V = IR Assuming 12.6V 12.6 = I* 0.02 I = 630
So yeah, it could hit 600A, if only until it got hot enough to melt something or change the chemistry
Well that explains why it hurt so much.
They say amps are what kills you. It’s not true. You need a trifecta of current, Voltage and resistance. And usually it has to go through your heart, causing an arrithmea. Though I have seen people get their hands blown off on a 400V system.
Your body has a very high resistance. If your hands are sweaty and you place them directly on a couple of 12V terminals you might get a tingle (I’ve done this several times on accident on 24V bateries).
That’s why I always laugh at the movie trope of people being tortured with battery cables.
But there’s more. Electricity takes the path of least resistance so in this case it would probably bypass your body altogether.
But as soon as you connect this you’ll get a giant spark (basically how welders work). If that doesn’t perturb you and you somehow successfully connected this, it would get REALLY hot and burn you before it shocked you.
It has been 20+ years since it happened, but I’m pretty sure I was standing in a little puddle, or my hands were wet (can’t remember which), and my wrench just happened to bump the positive terminal and it was like “POW! Right in the brain!”. Thankfully I didn’t latch on or anything. It was instantaneous, and over in half a second, but it rocked my world for that half second or whatever it was.
My guess is you were burned more than shocked.
Wait you can get shocked on a car battery??? I thought 12V was too low for you to feel.
Just remember to cut it when you dispose the battery, so that sea turtles won’t get stuck in it.
Perfectly. Legal. Thrill.
Hmm. Giving it away a bit here. He cringes well before it discharges.
Obviously, Mehdi is an electrical engineer. The “dumb guy making things explode” is a persona he puts up to teach people about the dangers and wonders of electricity.
That’s… immensely cool. I wish him luck in his dangerous endeavors.
Does he have a youtube channel or sth
ElectroBoom, 6 million subs if I’m not mistaken
ohhhhhhh I’ve heard that name, but I’ve never watched him.
I should.
Oh he new it was gonna be spicy
Ooo a budget space heater
I was going to say, automatic heating on the handle. Nice features!
It was the last thing they made
With that hand, anyway.
Say you made this, but insulated… does a car battery have enough structural strength in the terminals, though? I imagine you’re left holding a handle with two terminals and half a cell stuck to each.
I work in an auto parts warehouse:
Yeah, they’d be fine. It’s surprisingly difficult to break them apart. The load would spread out to almost the full width of the battery on either end (ie the plates attached to the terminals against the underside of the lid). Some of the models I ship use plastic straps that hook onto the seam between the lid and base and you can really toss em around before they take damage. (some people are less than gentle with parts :/ but I’m not the manager so 🤷)
Some of the larger batteries with screw terminals might not survive, but the ones where these clamp style are used would be fine.
… It’s conducive
Say you made this, but insulated…
Ah, I missed the root comment
And a face full of acid, I imagine

In space, nobody can hear your explosive diarrhea?

You just gotta use long screws to firmly connect it to the battery, or else it slips off.
Took me a min to realize…
I am a “ask me anything” Tech, ask me anything!
How long can you hold the handle once it’s attached to a fully loaded battery?
For the rest of your life
Not really. You’re not gonna get a shock, you’ll just get very severe burns.

Why does it smell like BBQ in here?
