The IST's 15" TPU Project~~{The SM15}~~

well this is my first attempt at the big Ring i have built many small rings but no big one's in this picture you see i used a cereal box and a screw and a pencil made a circle on the box exactly 15" i then taped down the easyflow 18 GA speaker wire around this circle i made 10 turns around the circle then ran the 2 ends across the circle to the other side of the circle to allow some length of wire to work with the total length of wire was around 43' this collector was wound counter clockwise here is the pic

in this picture you see the collector and 6 control turns and it fit perfectly

the controls are 100 turns of 22GA speaker wire the length of the controls was 11'6"
i used 2 zip ties between each control coil for spacing to keep things even all the way around the collector at the start and the end of the coil i put an extra zip tie because there was a bit larger gap which worked out well

i then went along and cut the control wires at all the same length from the collector and installed block connectors on the ring with zip ties i put 1 block connector for each control coil

in this picture you can see i hooked up 3 of the 6 control coils and based there connection at the top of the coil where my collector leads come out i installed 2 groups of 3 block connectors to feed the controls all controls are wired to 1 place and the signal comes in to all 3 at the same time

then i found some of these little guys there are ferrite rings i found them in cordless drill battery chargers and computer power supplies and those kind of thing's i striped off the wires that were wound around them
