Re: Circuit Common?
Thanks guys for your input. To clarify things I think I should supply some more information on the circuit I'm planning to build: <p>The project is a wireless remote control gadget, consisting of a transmitter and a receiver. The receiver circuit calls for a 12 volt AC source. However, the article s...

Circuit Common?
The instructions for a circuit I'm planning to build say to connect the negative side of the power supply to "circuit common." Is "circuit common" ground?

Re: How to Read Schematics?
no_vice<p>So, if I see a schematic showing several instances where a line goes from a component to a ground, thus showing several grounds that look isolated from each other in the schematic, in reality all these isolated looking grounds in the schematic are connected by copper running along, say the...

Re: How to Read Schematics?
Cato,<p>It sounds to me from what you and Russ Kincaid said that I should start with a perf board. When you say "wiring between the pins," I take "pins" to mean the leads from a component.

Re: How to Read Schematics?
Harold,<p>I'm not sure what you mean when you say I must "lay out" a board. How do I get a board containing all the lines of copper that tract the schematic? Do I get a blank board with all copper on one side and then cut out the copper I don't need, leaving the lines of copper I do need?

Re: How to Read Schematics?
No_Vice,<p>What are "pinouts"? Also, I've seen schematics where a line goes from a component to a ground in the middle of the diagram (in addition to other grounds in the diagram). Do I just have a single blob of copper (whatever that is called) for that one ground -- sort of like an islan...

Re: How to Read Schematics?
Cato,<p>Thanks for your reply. I am referring to detailed schematics. In fact the project I have in mind appeared in the April, 2002 issue of Nuts and Bolts (Building a remote control transmitter and receiver to power appliances such as a lamp, radio, etc.). The article contains a parts list supplyi...

How to Read Schematics?
I'm trying to learn about electronics and have a project in mind that I read about in a magazine. The problem for me at this early stage of the educational process is that I can't read schematics. I've learned many of the various symbols for components, but I can't understand how to actually connect...

Radio Shack Key Chain Transmitter & Rec.
I saw a post earlier today on an RC switch for a room light sold at Radio Shack (Key Chain Transmitter and Receiver) and now I can't find it. Does anyone out there know where I can find this post? Thanks.
