ok well you were right about needing bigger coils im so suprised at the complex ness of this project .. i was relly wondering why it is soo hard due to the fact that relays them selfs are coils and have a great response and pretty good pull on the contact spring .. so itt crossed my mind to take some of the relays my dog chewed on .. (lil brat.) and take the coils out and line them up now with say 6 of those fired at the right timeing should advance a steel bb ball threw the tube advanceing it every time it fire anothrr coil right ? not alot of power but results right ? dident do this but im having a much harder time with supply some the coils with the relays.. i belive they may be welding them selfs in side but not sure every 5th try i get some kind of action out of it i bought 100 ft of wire and used about 60 so far to make 3 coils 20 feet in each 6 or 7 layers tall 8 wraps wide soo they are taller then wide ..seems to work much better ... but even in crud use like just doing one coil and one relay and one cap with the charger and one aa battery all hooked up and a big push switch .. im only getting a scrw driver bit to move 6 inchs ... my hopes are to only need enough power to use steel b.bs from a bb gun and some how control the timeing that will = power with the arduino in the end ... relays work but not well the 3 coils seems much better then the complex 10 setup ive burnt up 3 relays and 5 flash cammras and a multi meter and some pcb board its becoming expensvie hahaha...
soo i have to ask couls i get some specs on a good working coil to make and may be i can mod my relays to handel more current.. i was also gonna ask would chargeing the caps with say 12 volts 20 amps have the same affect as useing the chargeing transfomer ?
