Hi,
anyone got a schem for the Oatley Electronics " Glo Plug Driver " published in Silicon Chip in March 2000 ?
Bugger about the US archive being bluffed out of carrying this old stuff.
If you do, can you post it somewhere ?

That must be the one, wot an awful POS.
I was curious cos a design of mine was published in EA magazine in the late 1980s in "Circuit & Design Ideas".
Nothing like the above.
It was buck regulator with a pot-core inductor and loop feedback to regulate the actual temperature of the coil in a Glo plug. When the engine started, current backed right off automatically, avoiding burn outs.
Good efficiency, it drew a steady 500 to 700 mA from a battery over a wide voltage range with plug attached. I used a 2.5 Ah gell cell.
OTOH - the Oatley driver draws 20amp spikes of current with a 5 to 10% duty cycle. Only works with a car battery or Ni-Cd pack, any operator errors burn out the plug.
