Subject: ok design?
im trying to build my first coil...this is the design i plan to use
powersupply: auto ignition coil powered by a motorcycle battery, i estimate
the auto coil to be about 45 watts, 30kv 1.5 ma. frequency: adjustable from
1 Hz- 2khz
primary cap: 45kv, 640 pf, consists of 30 3kv 4,7nf caps, 15 in series, in
paralell with another series of 15.
spark gap: 2 pieces of metal bent in L-shape, adjustable with two screws.
secondary coil: 700 windings with 29 awg on a 10 inches long form that is 2
inches in diametre. (25 cm long, 5cm im diam.) on the top of the secondary,
im going to put a nail or some kind of sharp point, since this is just a
small coli.
primary coil: Standing coil, i dunno how many windings it should be to match
the cap. i plan to use some kind of normal thick wire.
chokes & safety devices: none, this is just a small coil thats not on the
power line. maybe a safety gap on the cap.
ill place all the components on some plexiglass
does the above and below seem ok?
