I am more confidant in using capacitors in my DMR build, because I just tried on purpose to connect the wrong poles and nothing happened. Used a AA, 9v, D, and then 3 Ds hooked up to each other. Am I doing something wrong?

I'd also like to know how many of you use them, if there really is that much difference in trigger response (im not going for ROF), and how to make them explode. Also, I ripped a few of an old circuit board. I'll give the uFD and volts later, but how much uF do I need total? An do I need to have a voltage exceeding that of my battery?

Edit: I use those different batteries one at a time in succession besides the 3 D batteries. Those were hooked up to each other as stated.

If your using a combination of batteires it isn't a capacitor, I thought a capacitor was a Series of metal plates.
Off topic but cool - we are going to start making supercapacitors which are on the molecular scale and store huge amounts of energy, we do this by making the plates from graphine, each plate being one molecule thick. A sheet of graphine one molecule thick can hold the weight of an elephant on the surface area of a tip of a pencil!

Holy crap that's amazing! Sometimes I wonder what goes on in the minds of the people that think of this stuff...

But no I meant the batteries were the source of electricity to flow through the capacitors. I had a battery with wires connected to both terminals, and each wire from there connected to the opposite polarity terminal on the capacitor. I heard on AM that if you (accidentally, not really in this case) Connect the wrong polarity wire to the terminal on the capacitor, it will explode. Maybe I didn't wait long enough. I only had it connected for ~30 seconds.

Speaking of electrical such and such, I heard apple is applying for a patent on a hydrogen battery that's supposed to last a few WEEKS. I know that hydrogen fission (or fusion?) can power a whole city on a bucket of water for a great deal of time, but I can't imagine they'd fit a nuclear fission device into a battery!

It will be a hydrogen fuel cell, not fusion. No one has made fusion work on a net gain yet.

On the capacitors here is a thought - you could make a replica AN-94 that would work the same as the real on. By using a capacitor you could get a really high ROF for a couple of rounds until the capacitor had discharged. Then the rest of the rounds could be fired from battery power. Then when you stopped firing it would recharge the capacitor.

For those that don't know the AN-94 is a Russian rifle that fires the first two rounds at 1800rpm, then the rest of the burst is fired at 900rpm. There is also a 2 round burst mode that fires 2 round bursts at 1800rpm

Also, the Mexican Quetzilcoatl, has 3 round burst rather than 2. Also has a mechanical recoil system so that you don't feel the recoil until all three rounds leave the barrel.

I lol'd at the more you know pic.

ON the topic of hydrogen - It is extremely inefficient, we can only extract it by using using oil, at the moment it uses as much energy to extract as you would get out of it. At the mo it's only a feesable fuel source at the moon and mars.

While on nuclear energy - Sorry if I am going to go on a rant here but - It is absolutely ridiculous that we are not using more nuclear energy, windmills, solar panels etc. are terribly inefficient. My country last year spent over 1 billion (A large sum for Ireland) building windmills. We will never get back this energy, the amount of concrete and metal used in the building of these damages the environment much more then it will ever save it too.
You may say, "oh what about nuclear waste and meltdowns etc." Yes you'd be right, but if the entire world used nuclear energy the amount of waste created per person would be the size of a golfball.

But that isn't the best bit- We are NOT using the right source for nuclear energy - Instead of using depleted uranium and plutonium we can use Thorium.

Thorium is three times more abundant then Uranium, DOESN't create nuclear waste, in fact it eats it, it is much easier to extract and damages the environment less, a Thorium reactor CANNOT have a dangerous melt down meltdown, it doesn't emit as dangerous particles and then, it doesn't have to be refined as much to use.
We even had a working prototype in the 60's and now India are making a load of reactors, they plan to have 30% of their energy made by Thorium in 2050.

You may ask why we don't use this miracle fuel source? - Simple, in the 60's they wanted nuclear weapons, you can't make nuclear weapons with Thorium. And since they have just kept the existing extracting and refining plants.

On fusion, they have only made somewhat successful cold fusion so far, when we break it it'll be an amazing fuel source.

I'm 16 BTW.

I'm 16 BTW.

I LOLed most people are surprised at people our age if they can take apart an airsoft gun and put it together again

 

[inthetallgrass]

Yeah, I find I used to get slightly less respect cause of may age at my field, that's gone now

Dark matter and anti-matter, those are two things we should try much harder to tap into, just we have to be careful not to blow up a small country doing so .... near impossible too.

 

[swordfish1227]

As long it's the right small country no biggie, right?

 

[WorstInFinlanD]

Depends who you ask about it.
