What was your first circuit? Do you still remember it?

Hi, I found out that there were already threads about something like your first multimeter, etc. Now, I think sharing (and maybe talking) about our first circuit would be fun as all of us had our beginning days. :) ...And hopefully, it could inspire and motivate some beginners and newbies too.
So here we go, let's start with mine.
Back in the day, when I was 8, I was really interested in analog audio stuff. I was not really interested in electronics back then, I just loved connecting wires (and lots of them) on audio systems ::). But while surfing on the web, I was directed to this circuit which says that the LEDs will light up depending on the intensity of the sound.
I then went to my local electronics shop to buy some parts and connected some bare wires to the transistor. And to my excitement, it worked perfectly!
This was a thing of beauty for me and so that's how I got into electronics.
Anyway, that was my beginning. What's yours?

Hooking up some music playing IC.

I don't remember what was exactly the first circuit I built, one was a rather big and loud installation:
My grandfather complained about the birds picking the best cherrys from the big cherry tree we had back then in the garden. So I wanted to help him out with an automatic solution:
I hooked up a lot of electromechanical stuff (like a master clock providing a pulse per minute driving a uniselector salvaged from a PABX (fully electromechanical type, a cupboard sized box full of relays etc.), some relays, transformers, rectifiers to finally drive a relay on for some seconds every ten minutes. I even integrated a (also mechanical) timer to stop the ringing at night.
The relay in turn switched (ac mains) power to a large telecom outdoor electric bell that I installed in the cherry tree.
The whole installation lasted for about half a day, since my parents were asked by the neighbours to remove the annyoing noise.
Other (more electronic) things I built can be seen here:

Of course I remember!
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.
