TRIAC Light Dimmer |

| Hi -- thanks for the video & schematic. I am new to circuitry, and there are a few things I don't understand in this schematic/video.
1. What is the purpose of the neon light? Does it do the same thing as a DIAC?
2. What does the capacitor do in this situation? What purpose does it serve?
3. In the potentiometer pot, which wires go to which port? 1, 2, 3? In a traditional dimmer switch I bought at Home Depot, it only had black wires (and a green ground). Would the 'black' go to port 1, 2, or 3 in the potentiometer (i got a 600V one).
4. If I want to make this a dimmer switch, do both the white and black wires from the plug/DC adapter need to be soldered to this circuit board?
Thanks in advance, your video is really cool.

| it works... Although it's difficult to find 2N2222 & 2N3904 transistors (Editor's notes: Those are the two most standard NPN transistors in the world.) |

| Why follow the crowd? A neon bulb is a known gas discharge voltage reference. It may well be that it doesn't do as well as a diac, but let's face it, a light bulb dimmer ain't exactly rocket science!
I'd thought (yesterday) of using one to reduce 120VAC to a clipped +/- 60 V or so, rather than use a step-down transformer for a zero-crossing detector. Why? Faster changing AC voltage going in than 12VAC would be to the comparator.
Get a life, folks, independent thought that doesn't always look quite right keeps the brain stimulated. Or did you come from a modern college that crushes that? |

| Much better if you will use a diac than neon lamp. |

| The neon lamp in the circuit above (L2) can be replaced with a diac. When the diac's breakover voltage is exceeded, the triac gets fired. What do you think of this modification? |

| 1: how can you make this use more channels (16 or so) and
2: what actually controlls the dimming of this and
3:will this work with leds and not have a flickering problem ??? If not how can you make it work with leds so there is no flickering problem as it is dimmed.. |

| Can anyone direct me to specs for an "8TA12"? I believe it's a Triac. It's used in a lamp dimmer. I'm looking for a drop-in replacement.
