hello i was just wondering wether you coul tell me what material you used for the barrel of the par-1 and the length and width of it, and whether i can use aluminium for it, also would you be able to give me the template for you par-1 casing as well thanks in advanced
hey i found a formula that determins the total length of wire needed for a coil. not 100% accurate but pretty close. not sure if it helps, but i just thought i'd tell you.
T/2(((L(pi*D))/G)+((L(pi(((T-1)G)+D)))/G))= length of wire needed for a coil. where L= length of coil, G= wire width, D= diameter of barrel, and T= total # of layers wanted. pi is pi, 3.14
Hey. I love your coilgun Instructable! Terrific work! When you have time could you please make a railgun Instructable? I would love that! Thanks so much!
I understand schematics as far as what goes where. On your schematics there is no call sign explanation and that is where I have a problem. I see resistors, diodes, your LED's, 555 timer, 3 digital displays, relay, Scr's, capacitors, coils, chrg led, and a few others. I just am not familiar with PNP, and some of your call signs like U5, U4. They state IC....... and some numbers as well as something called TANTULUM, I think. I look up PNP on Wiki but it was a vauge explantion of Transistors in parellel. I wish they would give schematics. A picture is worth a thousand words. So could you help me with a list of the call signs and what they are? Unless your feeling ultra-nice and wouldn't mind drawing up a shematic with 2 mosfets, 2 pair optical sensors, and a 556 along with it's needed parts. :)
