Light Dimmer question.

Postby grisha on Mon Aug 20, 2007 9:26 am

Hey guys, my first post and its a question!
Im currently making a home made light dimmer for my night lamp which when turned on at night time hurts my eyes. I first want to test this circuit that I am making on a small 24W lamp with my 12V AC power supply.

Im not a master in electronics but getting there.
I have already made a AC to DC converter that works :) but I need help with the logic circuit to control the triac.
I was thinking to have one that can change the timing as well so with a viriable resister.

I was just wondering if you guys could give me some hints/help with the logics.
Here is what I thought up so far.

Thanks for your help.
