Raptor12 Wireless AC Dimmer

Found a very intresting chip.

It basically replaces the capacitor dropper. And based on my estimations it just enofe to handle the peak power draw of my curcit. Simpler and smaller board. I think i will see what i can come up with using this chip.  I think i can shrink my board down to fit in a smaller 1inch pipe enclouser.

As normal i wasn't fully thinking...

With the full wave rectifier, i have a situation ware the triac constantly sees gate voltage on the inverse of the ac wave. Because the negative of the micro GND is sometimes at 0 and 115v. (On top of that is is out of sync wiith the mains ac.)Anyways the solution is fairly easy i just was not thinking

No mod wires this time just oddly connected rectifier(useing it as a diode.) SO now micro gnd is the same as triac power rail. Good thing i had 9 boards to messwith:)

And i have another Toy in the mail.(may as well do this right)

Still with the vreg issue in the back of my head i continue on.

Alright I added everything and still no smoke.(that i could see). 

Anyways, I was abusing the power supply and every thing was going good. Then a found an issue, the 3.3volt reg is very sensitive to power spikes. SO i was rapidly unplugging the power and the little vreg went poof.

So here what I think happened when power was applied, the zener diod that shoudl be cliping the voltage above 4.7 take a few us to start functioning. (not totaly sure)

Normally I believe the capacitors drain prevents the initial spike, from charging up. SO when i let the cap get below 4.7v then reapply power the surge goes though.

I am not total sure, just a guess.

Here is the diod i was useing.

I will let the video speak for its self.

Assembled just the psu part of the board not really sure if its groan work or not yet, and i didn't want to wast that $2-3 micro just yet:)

I have been fan of elecrow for a while but there habit of sending you a picture of the board when they ship is just evil:)  And so begins 2 weeks of waiting for the mail.

Specs and inital designs.

Its wireless
--NRF 2.4ghz
Cheap
-No transfomer
-optio isolators
-driver chips.
Expandable
-4/8/12 channel.
-Add 2 expansion boards 4 channels at a time.
Low power
-20-30ma @ 5v consumption.
Small Form factor
-Enclose in a cheap 2inch pipe.
It should be around $17 , competing with wired diy controllers that cost $60+

Triac choosing 

Figuing out what my max current rating should be.

Thinking about 10amps max now (really 12amps), Even so that bigger triac really has no use. Accept if you need extra current for one or 2 channels.

12Chan = .8 Amps Each

8Chan = 1.25 Amps Each

4Chan = 2.5 Amps Each
