What was your first circuit? Do you still remember it?
dos:
First was probably what another poster said, hooking a small incandescent lamp to a battery, adding a switch, etc. Second-1000th was stuff on one of these
I remember wanting to get into electronics at a really young age and my dad first just went to radio shack and bought a few random parts, like a strip of resistors of one value, a two-pack of electrolytic caps, and a LM7805 (I still have this in it's package!). No breadboard or anything :D When he realized that there was nothing I could really do with that stuff he went back and asked the salesperson what to get a kid for learning electronics and he recommended that project lab, which I must still have somewhere. I spent hours making the dumbest things on it (lots of noisemakers if I remember right) but it really helped to familiarize me with the basics, and I remember the book it came with being excellent.

It was a 'square' 4.5V battery and a light bulb.
As a kid, it was totally mind blowing to discover that you don't actually need a flashlight to light the bulb.

Pretty much mine too, but with 2 D cells, a wire and a bulb. My grandpa showed that to me.
I got home, and figured the mains plug must work the same way, one side is negative, the other is positive (I did not know the concept of AC or DC). That's when the paper clip came out, and a C9 christmas light bulb. I got it to light up and thought it was the coolest thing, until my finger slipped and I got a pretty nasty shock. >:D I was probably like 10. My exploration of electricity just kind of grew from there. Though I never really got into electronics itself other than taking things apart or seeing how much voltage something can handle before it blows up, my interest in component level electronics was always kinda around but never really pursued it till recently. I'm still a newbie in that respect.

Of course done crystal radios before and what not, but this was the first to fit in a plastic soap box, to have a battery holder, etc... Must have been 10-11?
Gary350z:
My first circuits were the Heathkit Electronic Workshop "19".
This is about 1967 as far as I remember. I was about 10.
After seeing this post I did a google image search and found these photos.

Five or six years old, 4.5V battery with screw terminals, wired to a light bulb and switch mounted on the roll top of a cigarette box so the bulb illuminated my Grandad's cigarettes when the roll top was opened, later replaced with the filament from a gas lighter so he could light his cigarettes when the roll top was opened.
My first radio was a crystal one with high impedance earpiece, again built with Grandad and around 7 years of age but my very first soldered project was an 'electronic dice' which was a 555 and 4017 on Veroboard.
Sadly I didn't realise that I needed to cut tracks on my pristine lump of Vero but a very nice bloke at Van Bek electronics in my home town showed me the error of my ways and at the age of 9 or 10 I had built my first 'proper' electronic project.
Oh, and it was a 126 Bell battery. I used to save pocket money to buy those. Wish I still had one or two, just for nostalgia.
