Exactlly, now you got :lol:MARINE1142 said:Got it. I know what you mean too. There aint no fun in buying something when you can make one and say ohh that yea I made that.
This can be used to control the brightness of a bulb or the speed of a small motor.sammy004 said:Can anyone help me out on building a real simple 120volt light dimmer
sammy004 said:I also found this on the net https://www.aaroncake.net/circuits/dimmer.htm
but do I have to use a neon lamp for L2 or can I just leave it or use something else also that is a 40502 triac what exactly is the rating of that piece.
sammy004 said:What are supression components and where do I add it in the circuit. also does my diac need to be a specific rating.
I want to know to!!Misterbenn said:could some one explain what a diac is please.
and what there used for?
from the circuit above i can see its used to trigger the TRIAC, why?
It resists current. It's those squiggly lines on the schematic.PS Misterbenn what is a resistor?

We were amazed to discover that foreign language publishers generally redraft the figures, using funny little boxes (instead of handsome zigzags) for resistors, etc., then festooning the things with unpronounceable labels and captions.
