No, none of the Sources had them. They had PC and IC boards but I believe I'd need to solder and I don't even have soldering material let alone know how to solder anyway.

But I am using steel springs to connect my wires. It's just this cardboard box with small holes that many small steel springs are inserted in. And I just put my wires on those springs.

Torben -- "Is the purpose of the exercise to show that you can design the actual circuit, or just to show that such circuits *can* be built from plans?"
Not even any of those. It's just to do a research project and build any model. It's not even related to circuits. It's an open project and I wanted to do mine on alarm detection methods. Like, some girl in my class today presented and she did her project on quarks. Her model was just like a sock with two styrofoam balls in it. Of course, she did get pretty much destroyed by the teacher though..

John -- Which pins are on the transistors? Well um, Pin 1-Emitter, Pin 2-Base, Pin 3-Collector. Is that what you mean?

Okaay ...

got to feed my cat, she's actually rattling her dish.
Back v soon

Torben--Well it's a small town near Lake Huron in Ontario. And it really doesn't have much. Anything useful has probably already closed by 6pm (atleast The Source and our local internet provider store, which I believe closes at 5).

If it's really needed, I can try to get a camera. One of my friends may be able to lend me one. But also, what about msn messenger or skype?

john1

are they like this ?

If you can borrow a camera,
it would help,
but i think we'll struggle through.

Mastercraft? You must be Canadian.

How about taking apart one of those solar lamps, cheap and have most of the parts you'll need.

She's getting on now, nearly twenty years old.
I tell her its white wine when i put her milk down,
and i tell her its sparkling mineral water when i top up her water.

She's not impressed.

Those are the PNPs, since the emitter is going in. Yeah, mine are like that (they're shaped like the one with the straight leads). But the Collector-Base is 60V and the Emitter-Base is 6V on mine. Although I think you were just trying to verify the shape. Also, in my circuit, I was trying to use one of the NPN transistors that I have. Both types of transistors that I have are shaped the same way.

And I'm trying to get a camera.

Lol, and I am refreshing. It's just I'm typing when you're telling me to refresh.

john1

yes thats fine.
1 emitter, 2 base, 3 collector,
with the flat on top,
and the pins pointing toward you,
Ok.

Have you tried the buzzer on the battery,
is it Ok ?
