My New Toy

[sganc4life_4]

Well, it is the RACING non specific

[CBFryman]

mmhmmm....and cassie acts like im the first to place non racing realted stuff in here...
especially since my other thread is about racing...

[-Josh-]

I dont see a problem with this thread here, why dont we have a discussion on V.E. Chris, that would be auto related as well if that's what someone's looking for.

You want specs you got 'em... ive laucnhedevery food product in my house that i could conceive and fit into the barle. this includes:
Orange
Biscut
Raw Egg
Hard Boiled Egg
pakcets of ketchup
breakfast bar

and a few non food products includeing:
1" PVC wraped in a rag as wadding (took out the end of a branch)
3/4" Bolt wrapped in paper as wadding
and
little shampoo bottle filled with water

The orange was probably the farthest at an estimated 100yds (i fired it into the woods into a wild grape vine patch...only my dog and the neightbors cat knows what is back there). all except for thoes that fell apart (egg, biscut, breakfast bar) had about 4.5 sec of hang time meaning i had it angled way too high.

after a little (cough lot) of trig/physics i came up with the exiting velocity of the orange to be 150mph give or take.

but check my math if you dont beleive me (and understand this before you try and throw up a BS flag).

Vf = Vi + A * T

0m/s = X + (-9.8m/s^2) * (2.25s)

Vert Vel. = 22.05m/s

Sin45 = (22.05m/s) / X

X = Barle Vel. = 31.2m/s

31.2m/s * 100 = 3120cm/s

3120cm/s / 2.54 = 1228.35in/s

1228.35 / 12in/ft = 102.4 ft/s

102.4 * 5280 ft/mi = 540672

540672 / 3600s/hr = ~150mph

But to check this w/ my estimated distance

22.05m/s * 4.5s = 99.225m

99.225m * 100 = 9922.5cm

9922.5 / 2.54 = 3906.5in

3906.5 / 36 = 108.5yds....

close enough for government work

[CBFryman]

oh so that means 0-150mph in ~ 2.5ft

My potato gun > F1, F50, Murschelargo, and Bugatti Veron

[sganc4life_4]

Whered u find the sparker at lowes? I searched but Im somewhat curious how you installed it.

[CBFryman]

in the grille section...there was 2 boxes of them.

As for installing it i simple screwed 2 screws that where long enough to make a 1/8-1/4" gap and soldered the leads from the sparker to each screw making a circut.

Sorry i had to.

I won't lie sometimes you scare me.

[Sleepr awd]

this is my first time in this part of the forums, and this scares me.... thats freakin' awesome though, you need to shoot something that will explode in mid-air, try using bottle rockets and fuses and stuff and stick them into a potato, and hope it doesnt' prematurely explode, 3-4 bottle rockets crammed in a potato and fired straight into the air would make a lot of mush

[CBFryman]

hehe, onion soaked in vinegar over night is sapposed to make a purple trail of flames...lol trying it tomarrow night

[nissanfanatic]

Okay the rednecks down the street from me make thier potato guns work just as well without all the 1337T3cHnozzz work.. Its just a potato gun. Explosions, fire, destruction all cool...

acting like you need formulas to build one correctly, not cool....

[CBFryman]

i dont need formulas... however there is a science to everything. it it means louder boom, bigger flash, or potato goes out of sight sooner... flexing your brain is helpful.
THAT is just seeing how fast the potato is travleing the hard way, in actuality it is probably well over 150mph as i didnt account for wind resistnace. and there arent many radar detectors that go much higher than 150mph

Rednecks can make their 383 fast in their home garradge...

but if it means it goes faster, sounds better, and is all around sexier and more reliable... Chevy and Ford are willing to put a little thought/mathmatics into it...where as dodge is that redneck putting the hemi in every other vehicle they can shove it into.
other companies like BMW, and Mercedies put evne more thought into the cars we get and millions of dollars of science into F1 cars...
and then Porsche, VW (lamborghini), Ferrari, Maserati, excetera take it to the max to make the fastest, sexiest, best sounding cars around...

which would you rather drive? a dodge charger with a Hemi?
Or a Ferrari F430?
the only condition is to get the ferrari you have to flex your brain.

[drftk1d]

man, you have too much time on your hands

why dont you be like a normal kid and drink and smoke or something

[nissanfanatic]

Ford, Chevy, Ferrari, all of the above aren't building potato guns out of PVC pipe...

Flexing your brain..hmm.. I guess I'm not too guilty of that*looks at his car* NVM...

[CBFryman]

you really dont get it do you? Unlike 99.99% of high school students, i take what i learn and apply it to things i enjoy and take it a step or two further by using what i learned to make what i enjoy even more enjoyable or to apply it and figure other thingso ut on my own... i figured out motion in two directions and projectiles weeks before we covered the chapter. I applied what ive learned an figured out in physics to estimate the exiting velocity of the potato.
i didnt put it there to seem like i was cool or smart, i put it there for anyone who questioned it could check my mathmatics to make sure i calulated correctly.
Besides specs where asked for. you ask for specs on cars 0-60 and top speed are commonly included with horse power, wheel base, and GVW... you ask for specs on a gun Barle velocity is very common if not standard.
