Hello, folks.
I've done a transistor ignition kit for my engine, it still uses the points in the distributor but I'm thinking in changing them to I.R. or Hall effect...
I've already bought a Hall effect sensor (or transistor) and a pair of Phototransistor and Infrared LED and made some experiments on Protoboard..., they did work, but they have their own details...,
If I use I.R. I need a chopper to turn on and off the phototransistor..., the problem I found is that I have to get a very dark material for this and stick it on the distributor's shaft...., besides of getting the proper resistors so they do not burn... any idea...?
If I use tha Hall efect sensor is a bit easier..., less problem with current..., but..., I have to MAKE magnets the proper SIZE..., and need a SUPER GLUE so they don't fly away when in high revs...., again..., any ideas?
Thanks :-)

I'd use a Hall effect sensor. I would think an optical sensor would get dirty and beome more unreliable.
Most electronic ignitions use a hall effect sensor.

I don't think I've ever seen IR used. Too many failure points (dirty, stray light, etc.). Hall is used extensively in cars, for ABS sensors, crank sensors, ignition, etc.
Another type of sensor (used in Mazda rotaries, for example) is the reluctor sensor. Basically a spinning magnet in the shape of a star generates pulses in several coils, from which the computer can determine the position of the crank

I have been using IR in three classic cars now for over 20 years, with total reliability. It is not affected by wear in the distributor. The ones I have been using are made by LUMINITION in the UK, they sell the choppers separately, although the units are damned expensive. Hope this is of some help

Since I've posted that, I have seen a Mallory dizzy that used IR, but the IR was sealed internally in the base.

I.R. or Hall for ignition...
