triac

Hi, I implemented the circuit from this video. After implementing, I realized a mistake, whenever the main supply switch turns on, there is an initial jerk (also visible in the video, the link starts video video from that point of issue) then triac operates as per gate voltage level on gate. Is...

I bought a damaged Lavazza coffee machine. After quick analysis I've found something in TO-92 case, which apparently exploded for unknown reason. It's literally in pieces, but I was able to find that the last letters describing the model were "8D" at the top and "30" at the bottom (see...

I build on bread board the attached schematic and I uploaded the attached code to an Arduino Uno. I tested each part of the schematic (the pot, the OpAmp, the zero crossing detector, the optotriac) and they are working. The problem is that when I start the circuit I got the attached screenshot...

Hi all, Is it ok to tie the output of multiple triac switching devices together to independently switch on a common load? I am looking to have multiple outside motion lights that are on my house, tied together so that if motion is detected in one area, that it turns the lights on on more than...
