/diy/ - Do It Yourself

>>1768400
beware when buying led bulbs, they must specifically support dimming or the dimmers wont work

if you just want a cheap dimmer get the normal leading edge dimmers that is how all the cheap ones work BUT don't buy the dirt cheap ones that just use capacitors for timing because they won't work with led bulbs, you need some that uses a micro to detect the edge crossings in the sine and time the triac triggering correctly >>1766423 this pic is an example of a diy leading edge dimmer that uses attiny13
and this is the schematic for it, it is very cheap and easy to make
and if you can into arduino sketches you can add cool functionality like remote control or blinky effects and such
