Home made electronic timer. A D.I.Y. at home.
 

So I heard you think i'm dumb or something....

Oh ok.

Electronic ignition might be pointless but seems like a fun hobby.
It fits in the same place as the original timer. And i can plug a laptop into it to give it a different tune or run diagnostics.

Don't need points on the coils. Most of those coils probably never had points on them in my lifetime. Removed capacitors to save weight.

Big sparks.

Since most systems are designed to replace ignition breaker points, I have to assume that this system is different since there is no one set of breaker points to replace for a Model T. Do the coils still function or does it use a single ignition coil?

Aircraft ignition systems for the most part, use either a TCM/Bendix shower of sparks starting aid or they use the electronic Champion/Slick ignition booster that performs the same general function. These throw a shower of sparks in the combustion chamber that is generated through a retarded set of points in one or both magnetos. They work a lot like the model T system except that they are only used for starting the engine.

If you look closely you'll see the original coils but without their points, the wires were joined internally.

I noticed that and a jumper on the one that still had some of the points stuff on it but I wanted to be sure about what you were doing. I take it that each coil gets its turn depending on the position of the timer.

Removed capacitor's to save weight???

The increase in fuel efficiency (and full throttle pick-up) is impressive. It's like having a rebuilt magneto, but i didn't have to lift the engine or anything. Just swap a timer.

Yes.
I've patched up another 'junk' coil without points so now i have a full set.

I'm impressed and also have no clue what you did.

To induce a high tension voltage reaction out of the coil, a person needs a breaker to reverse the magnetic field in the core. An electronic ignition system requires an electronic breaker that fires the coil induction reaction. If it has a high rate breaker or an electronic vibrator for pulsating direct current then it can fire multiple sparks during the ignition process for each cylinder. I suppose it can work either way as long as the spark is hot enough to light off the fuel air mixture charge. It's not that different from a regular electronic ignition except that it has been adapted to the model T type 4 coil system. In that respect, it's a lot like the modern one coil per cylinder designs only it would still use a timer to fire them all at the right time.
