Tim 6 units can be easy to make, it is when you start to add LED's to help with timing and diode bridges to prevent cross polarity that things start to get complicated.

I see you are working with a micro switch. They only have a life of about 2million operations so when you have an engine running at 5k RPM (giving about 200 hours running), they can soon reach the end of their life, that is why people fit a Hall sensor and magnet, in theory, they should last forever.

Hello =) thanks, I made this before for school project i have no plan using it in engine, but since I am interested now in engine, I will make modification like putting heat sink and adding Led .. Plus it is better to use mehanical break so it will last longer
