Those were were the circuit board. basically for easy hook up/possible replacement of wires/sensors IF ever needed. You don't have to use them.
Thats acualy 2.2uF but will work all the same for the porpuse it is being used for.1. Is this:
Mouser #: 594-H222K33X7RL63J5R Mfr. #: H222K33X7RL63J5R Desc.: Ceramic Disc Capacitors .2LS 2200PF 500V 10%
the 22uf capacitor?
After re-looking at the data sheet for the SSR, the 560 resistor was not needed.2. If you revisit the parts list page you made (https://www.mouser.com/ProjectManage...sID=88fd98825d) did we forget the 560 resistor? It appears one is needed to hook the relay back up to the 12v source. I can just hit radio shack if need be.
I have attached a clean schematic in PDF form that will show pin numbers for the AND chip. In the schematic I have the push button in pin 1 and the sensor on pin 2.3. Where does the sensor go? I have been looking at this schematic for weeks and never noticed that I have no idea where the most important component goes!
If you're refering to the MC7812CTG and the .1uF and .33uF Caps than yes, if not than please list the parts you are in referance to.4. I seem to have several extra parts. Are these for the 12v regulator?
I will do some more messing with this in the morning in light of this info. I am sure you will hear from me again soon. Thanks.After re-looking at the data sheet for the SSR, the 560 resistor was not needed.
So just omit it and hook directly to the 12v?

I see that now. I was confused when looking at the schematic before.

Yes, those were the parts in question.
Remember 2 things, 1. when you make the final board one of the .1uF Caps are for decoupling the power supply to the chip; 2. ground all chip inputs that are not in use.
I am sure I will be asking about the .1uF caps situation. Thanks for mentioning tying the unused inputs to ground, I wouldn't have known that!
Wait a minute - 2,200pF is 2.2nF, which is 0.0022uF, or 1/1000 of 2.2uF.
Radio Shack doesn't have much in the way of caps around the desired size.
yes. the regulator, will handle a input up to 35V. the 16V you are seeing is because the PS is a unregulated 12V supply.I tested my intended power supply. It is pushing out over 16v (despite the lower rating on the label).
Which part? This way I can try to help more.Ok, you're going over my head now.
one ground, they are all tied together.Are there are two grounds here, or just one?
Yes, IE terminal block "power input".I am reviewing the schematic you posted (pdf version) and am unsure of the power regulator portion. Is the "power input" where the unregulated supply enters?
If your refering to the 12V above the circles with the + sign in them, than that represents the regulated 12V.If so, there are "+12v" and "gnd" at both ends. Where does the regulated power come out?
For eagle the IC1P represents the power pins for IC1 (the and chip, 4081N).Also, what is "IC1P" and "IC2"?
For the SSR the load has to be AC to see any thing. so you ohm meter wont see any thing.Do the "load" contacts on the relay have to be hooked up to something for it to open and close right? I was just using an ohm meter to check for continuity to determine if it would have let power flow or not. Maybe that was my problem.
