Re: [TCML] Off grid, medium size, 12V battery powered TC

[Ibrahim Khaleel <xbox1900@xxxxxxxxx>]

Another alternative could be connecting the battery to a DC/AC inverter (they 
are cheaply available) to power NST. Am trying to use Ruhmkorff induction coil 
connected directly to the Battery. Still experimenting.

Hi Jon,

I heard about this one a while back, a TC powered off 12 volts, a 555, some 
power transistors and a couple of ignition coils.  I heard some things about the 
transistors overheating in this design so you want some good heatsink and air 
circulation.  There are a boatload of comments about it as you scroll down the 
page.  I have not tried this design but I can tell you that an ignition coil 
from an older car, before cars had transistors in them, should give you a bigger 
spark than a newer model ignition coil, with the exception of one made for a 
racecar.  But as always, your ignition coil may vary!  Car scrapyards may be 
good for a cheap deal on a coil, in a car parts store I have seem them from 40, 
50, even 60 bucks a coil.  If you get one from a scrapyard make sure it is not 
leaking oil.
