Thanks for the link. I missed the original reference somehow.

Forgive my ignorance, but, will I be able to attach these relays
directly to the stripboard? I looked at the datasheet and all pin
spacings are a multiple of .1 inches. So I'm assuming yes.

Yes, It'll take about the same amount of real-estate as a 12-pin DIP
(hence gaps in the pin numbering on the pinout) it is of course taller than
a typical dip.

note that the diagram shows the underside of the device, datasheets for ics
usually show the top, so flip it over in your head and youll see that
tne numbers go counter-clockwise from 1 to the top (12) like on a regular dip.

Bye.

Okay Jasen,

Since you basically picked all the parts for me I'm going with your
suggestions ;) Below is the relay circuit with your suggested
modifications and parts:

I'm ordering the parts tonight for the relay circuits.

Also, I really want to thank everyone who took the time to help me
out. Keep a watch on this thread as I will report back my progress
and probably ask more questions.

The parts came in last night and I am eager to get started! I was
figuring on assembling and testing the relay circuits before
introducing the pic and usb uart module.

I'm planning on using a 9V battery to test the above circuit. After
some research I found that I can use a 5V voltage regulator for the
power. My question is what is the simplest way to simulate the pic pin
on the base of the transistor?

Either connect [PIN] to 5v on the regulator,
or through another 3.3k directly to your 9v.

probably connecting it throug the 3.3K resistor to +5V or to 0V will be
close enough for this.

Would you mind sharing the relay you were talking about? It's a lot of
work picking out the components! I was considering going the ssr route
but couldn't find a suitable one. So now I'm look at the general
purpose ones.

it and (url of) the datasheet are in another branch of this thread but here
it is again anyway.

Good news! I've successfully built six of the relay circuits above and
integrated them with the existing rf remote. Low and behold it works.
It took me the better part of a day to figure out the layout as well
as the assembly. (Told you I was a newbie ;)

Again thanks to everyone in this group for helping me with this
project. Stay tuned...
