The actual name is Into to Electricity and Theory.

So stop being a pompus prick. --- frogman

Well to be quite honest, most of the nuke med is still guesses. They still use cesium, but they are working mostly with iodines and flat out radiation. They are now using radioactive pellets that can be injected straight into the cancer spot. Which greatly reduces the "colateral damage" if you will.

lol, but as far a radon/radium is concerned, yeah, they learned their lesson.

So back to the topic, I want vids.

Great, monk's going into nuke med? Goiaina part deux anyone?

All joking aside, are they still using Caesium (Cesium) 137 for the gamma source in radiation therapy these days Monk? The history of Nuclear medicine is scary at best. If you research the lost artifact from the Piscataway incident, most of the early nuke med practiced was just guess-work. A bit of "lets just shove some radium up your nose for a minute..... and that should do it... I think..." or, if you look even earlier to the old days of "Drink Radium water! It'll make you strong and keep your bones healthy!" The sheer amount of quackery in nuclear medicine's history is astounding.

Sorry for the derailment, but it's a subject that's interested me for years.

Its actually a very difficult class. The only reason I didnt go into Electricity 2 was because I decided to go into Nuke med instead of Nuke power.

a variable resisitor (or potentionmeter sp) in series with the coil should be able to adjust velocity

Wow, I cant believe there was an argument over voltage and amperage lasting a whole page.

But to add my two cents. Enough voltage for long enough over the right part of the body will kill. No matter what the amperage. Instead of stopping the muscle, it will fry the crap out of it.

And I wouldnt bother arguing that. Because I got a 98% in my college electricity class.

Also. If you had some potentiometers or variable resisters, you can change how much voltage/amperage is going to the wires causing a slower/higher fps.

Dont worry about the patents and stuff. To be honest this is a highschool science project. So anyone can do it. But it is a very interesting idea. Im anxious to see how it all turns out.

I'd suggest going with a spring set in the receiver for the return stroke of the bolt. It doesn't need to be super stiff to give you a fast return rate at the moment due to the capacitor's charging time. The Mini, Badger, and Automag all use that system and it works well for them. Also, I'd definitely suggest getting a hold of an old AGD "foamy" for the front of the bolt to keep the ball breakage to a minimum. Also, have you thought about either using a ferro-magnetic or rare-earth magnetic core inside a delrin bolt? It would give you the same properties to accelerate the bolt down the barrel using your coil without the drag, lubrication, and recoil issues that you might experience with an all metal or all magnetic bolt. Also, I'd suggest going with an old Angel LCD NiMH rechargeable battery for your power source as you can recharge it and get a decent amount of shots out of it before needing to re-charge. It's long, thin, tubular design would also allow you to mount it below the receiver saving you some room up front where you'd normally put the 9v batteries.

Right now its about a pound with everything. I expect with balls, a body, frame, and anything else I add it will be 2-3 pounds.

Also just to make a note I made a 3D model of it today. I modified it with a few suggestions here and figure out a way to return the bolt without the charging coil.

I think someone asked how velocity will be regulated. Keep in mind that it isn't affected by weather (especially if metal isn't used for the bolt), so once its set its set. But I could potentially use switches to turn off sets of capacitors for large changes, and then a potentiometer for small changes.

To answer Frog man's question about how long the capcitors take to fully discharge, I calculated that the bolt, traveling at 300fps (to move the ball that fast) will take 555.556 micro seconds for the bolt to travel its full distance. That also means that, not taking into account capacitor charge time, and assuming that the cocking time will be the same as the shooting time, the gun could theoretically cycle 899.999 times per second. This, however, is no where near plausible. The fastest fire rate ever was 16666 rounds per second (Metal Storm).

Figuring that out is why patent lawyers get paid the extra-big bucks. It quickly gets very technical, but simply "apply Gaussian principles to paintball" could be a patentable design. Remember, Smart Parts basically patented "contact switch + paintball", and WDP basically patented "LCD screen + paintball". I don't know how much specificity you would need to patent this particular design.

Do I have to actually build the thing before I patent it?

No. You don't even need a model. Schematics will suffice.

Ticktock-ticktock.

What you have just done is "publish" your design/invention. Under US and Canadian patent law, you have 12 months from date of "publication" to file a patent application. If you don't file within that time, your invention is public domain and nobody (including you) can patent it.

In the EU and most of the rest of the world, you have already waived your right to patent this by publishing here.

Of course, any element of your invention that was not published is still eligible for patenting.

Do I have to actually build the thing before I patent it? If not I'll just build a model of it at school and print the schematics! I remember talking about patents in my engineering classes, but I'll go ahead and look more into it.

ok, so you got 10K V across the coil? yes...

ok, and whats the capicitors? you gotta make sure they dont discharge complety before the bolt has hit the end. (ill dig up the equation) 4 micro farads total

how many coils you got? enough, the ideal amount of layers varies on the diameter of the barrel, resistance of the wire, and volts that will flow through them.

and this is basicly the circuit? No. I have just given a rough outline of how it is constructed. There are still bugs to work out, and as of right now the timing circuit does NOT make the cocking coil function (still figuring that one out). There is a lot more to it than what I posted, you'll have to figure that one out on your own.

you charge the capictors, and when you break the circuit they discharge through the coil? so do you have a single trigger pull, break the connection to the source but connect the circuit to the coil? The connection with the source in no way affects how it performs.

lol, ya ya ya :-P

ok, so im going to try and help with this idea, I might actully try making something similiar to it for an engineering project.

(these next question are mostly to help me, not you)

ok, so you got 10K V across the coil?

ok, and whats the capicitors? you gotta make sure they dont discharge complety before the bolt has hit the end. (ill dig up the equation)

how many coils you got?

and this is basicly the circuit?

Right, and also electromotive force. Therefore electromotive force = volts...
