Development of an ignition system

Recommended Posts

Currently I'm developing a digital control unit that is to replace the breaker-points on a Honda XR75 -1978.

I will quoute some of my own blog post below. The blog that will be continally updated can be found on http://mechatronicsb...er.blogspot.com

Recently I've mounted a hallswitch underneath the flywheel who's task will be to trigger another circuit I've designed. That circuit in its turn will do more or less the same thing as the mechanical contact-breakers on the original system (main difference that this system will hopefully work). <...>

The hall switch is inside the green heat shrink tube mounted with stripes, connected with a lamp cable that proved to be practical and sturdy. The sensor output is surprisingly precise and clean.

Of the same reason that you sometimes want to make your own bread even if it can be bought at the store. It's fun do to something from scratch, you learn alot and you get full control over details and many times a better end product(at least when it comes to bread) 🙂
