Hi!
I am new to this fun world of electronics, so please excuse any incredibly stupid things I come up with!
I was just switching my first couple of light bulbs with a relay, and now i'd like to dimm them, just for the fun of it. I did find something online using triacs, but it seemd a bit complex, for starters. Thus, another idea popped into my mind:
Could I use two MOSFETs (as far as I could see, there seem to be a couple that can handle 110V) for this? I'd build a basic rectifier bridge with them, and if i switch one MOSFET on, the light bulb should only become powered half of the time of the AC frequency, right? So it should roughly be half as bright?
When I switch the second MOSFET on, then the full sine wave of the AC should reach the light bulb, and it should shine at full capacity?
If this is somehow not complete nonsense, what would be a cheap MOSFET that could accomplish this? Would a heatsink be obligatory?
Thanks,
M.
