@Winterrose for what 4000 car batteries would cost, i think there is more i could do with just 2000, and then use the leftover funds to buy copper, SCRs,....
...and deuterium

I want to find a way to get this kid 4000 car batteries

@MoTorChaser f/0.95 collects nearly 9 times as much light as f/2.8! getting the focus right is a nightmare though lol. plus these super fast lenses tend to have distortion and other defects. night chasing is still a great use case for them
English
@styropyro_ Wow, very nice setup! Thanks for sharing. I was full wide at f/2.8, 1/60,with high ISO on the A7siii, and it was very dark. I'll have to get a faster lens and try slowing the shutter in the future.
English
@MoTorChaser i was shooting with a f/0.95 lens on a sony FX6 at very high ISO. it's not exactly an easy setup to use in the midst of chasing but it is like filming with night vision. my shutter was only 1/60 here too when i should have been shooting 1/30
English
@styropyro_ Awesome intercept! I'm so glad you got a shot confirming ground contact. I wasn't certain from my position just east, but I thought I could hear it! . I also believe there was a brief tornado just before this one. How did you shoot this to get such a good exposure?
English
@Nsaw1G I don't think that alone would have solved the problem. I found that switch still conducted for a while after the plates were blown open, due to all the copper plasma that was made from the explosion. I think the best purely mechanical option would be a fast hydraulic actuator
English
@styropyro_ I know you're already working on editing the video from your YT post (can't wait for that haha)
But did you consider a vacuum chamber to put the contacts in? Either a vacuum or some sort of gas like sulfur hexafluoride like power line reclosers use for their contacts?

@DanielleFong @sendcutsend if that's 1" x 0.25" bar then it would last approximately 0.15 seconds carrying the current of my batteries
English
@Moria15606197 I quadrupled the stack. Full vid to come soon
English
@styropyro_ Are you reposting this, or did you hook them up again?
English
@DrunkPyromaniac @Jagil10410013 @BorisBartlog i've been meaning to try this! the batteries should heat up quite a bit too.
English
@styropyro_ @Jagil10410013 @BorisBartlog I know you're not. It's just funny to think of how much wire would be "needed". It'd be neat to put a FLIR camera or something on the whole thing to watch the batteries and wire heat up.
English
@DrunkPyromaniac @Jagil10410013 @BorisBartlog I'm not following any codes here lol. For ~1 second shots, the 40 parallel 4/0 copper cables I'm using are more than adequate. Their resistance is quite a bit lower than the batteries themselves.
English
@styropyro_ @Jagil10410013 @BorisBartlog According to my calculations, that current means you need 352 parallel 1000 MCM conductors -- equivalent to a wire 18-1/2" in diameter, or about $17,600 in copper wire a foot. 🤣🤣🤣🤣
English
@IluvIrt @Jagil10410013 @BorisBartlog Cold cranking amps are not interchangeable with short circuit current. A car battery can deliver FAR more current to a dead short on a hot day compared to the CCA test conditions. My batteries have the ability to briefly dump 3600A, but I only pull ~2000A from each one.
English
@BorisBartlog I was trying to build a switch for 400 car batteries wired together. Once I crossed 100,000 amps or so, an imploding z-pinched plasma would ignite in the switch, which would then detonate and blow the plates apart, giving the unholy oscillator in this clip.
English
@styropyro_ Looks like a moderately expensive failure ... but what are you trying to do here?
English
@SkyVelleity That's two 4/0 AWG copper cables in parallel being used as a timed fuse. The bulk of the load was in the switch acting as a molten copper squirt gun
English
@styropyro_ Was gonna ask "What the hell sort of a load was on this pack before you engaged the contactor?" but I think, a wrench?
English
@geerlingguy looks like those are only rated to deliver a couple megawatts 😢 i'm sure those pesky safety features could be removed though
English
@styropyro_ I'm going to duck and cover if you ever get access to a Tesla megapack.
