12F683 Light Dimmer Problem (SOLVED)

[DavyJones]

So sorry on the original schematic I had the gate on the triac on the wrong pin. The gate is on pin 3 not pin 2

I see you have corrected the image, right?

[DavyJones]

yes I corrected it and had to upload it again.

CAP100 is showing the wrong polarity.

Nice catch Jerson!

Sorry about that strangely I could not find a non-polarized cap symbol and choose that one and forgot to flip it. Let me search in the program some more to see if I can find a non-polarized one. There are so many symbols mostly based on part numbers. Hard to find just general symbols.

I found one finally it's not in the CAP category either. thanks for catching that.

Circuit boards are in. I realize that this differs slightly from my schematic I uploaded. I added a PBO-1-S5 to the board to supply power and eliminate the need for a wall wart for power. The PBO is really small and supplies 5v and 200ma which by my calculations is more than enough for this project. Also there are a few extra components on here which were added as the recommended filtering for the PBO. C1, C2 and C3 could have been SMD and L1 but they were out of stock so I went with conventional cap's,inductor for this version. The 12F683 can be SMD too but I choose a socket so I can mess around with the code and swapping out the processor quickly. The other thing I messed up on was for AC-in and Light I wanted to use 2 up terminal blocks but wasn't paying attention when I laid those out so they won't fit without running into the other components so for this version I will solder directly to the board the AC-in and light. I do notice every once in a while as the light dims and get's brighter there is a slight "glitch" for a microsecond the bulb will blink. It is so random and slight unless you are staring right at the bulb it's unnoticeable. It's almost as if there was a spike on the AC but since it happens so infrequently I don't think I could catch this on my scope to see if that is what it is or something else. Once I put this together and do some testing I was going to modify my schematic to include the PBO and extra components used for the power section. If anyone is interested let me know I will re-up the schematic
