Need help building a transistor electronic ignition box.

[grant31781]

I want to build a electronic ignition box for a engine i am tinkering with.

I need the unit to run on 12 volts and power a auto coil. I want to use a hall sensor for the switching.

TIM-6 - For use with 6 volt batteries (or 4.8 to 7 volts) on any engine type. The kit contains: (1) TIP42C Transistor, (1) 2N2907A Transistor, (4) Resistors, (1) LED Timing Light, (1) Hall Effect Magnetic Sensor, (1) Rare Earth Magnet, (1) Drilled Printed Circuit Board, Circuit Diagrams and Construction Notes. The circuit board is 1" wide by 1.35" long. Just to the left of the circuit board is the Hall Effect sensor and the dot just above it is the rare earth magnet which is just 2mm in diameter and 1mm thick. The LED timing light was added to the kit after the photo.

Now i dont know anything about these components. Will this work on 12 volts? What kind of resisters are needed and how would you wire this?

so, why you don´t make the switching stage optical instead a hall sensor???
tell me your e-mail and i send you the schematic of a circuit with an optical switching system designed by myself._

kind regards

How would the optical switching system differ from the hall effect? I actually started a new thread on this same topic..

This link describes how to use the HEI module with points. the point in this case won't switch much current and will last a long, long time. **broken link removed**

shortbus,

Cool screen name by the way! Hey thanks for the link.. It gives me more options in case my other idea blows up! LOL If you want to follow along or weigh in on this same subject? Here is the link to the new thread I started on this: https://www.electro-tech-online.com/threads/transistor-ignition-modules.118836/
