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

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.

My dad used to like to demonstrate how you could connect the batteries and bulb with 2 table knives.

I remember the first thing I plugged into the mains though, a metal can flourescent lamp starter. Wanted to see the glow, and pushed it into the 5A socket outlet and turned on the power, though I think I did at least remember not to touch it after plugging it in and turning on the power. The starter, along with the black Schipperkie, vanished in the bang, and while the dog did come back for supper, the starter was totally gone. Power tripped out at the new fangled distribution board in the laundry ( Installed a few months before as it had the important thing of earth leakage protection and thus was safer for use with an electric washer and clothes iron for Mom) and I turned it on again, when I recovered my hearing?and sight. Unique board, it had Australian socket outlets on it, thus the wiring was to regular SA 15A socket outlets plugged into the Australian rewireable plugs that came with it.

Quite similar to that  - I think it was in 4th grade.  We were studying some very basic electric concepts in science.  I think I had a C cell battery, some aluminum foil, pieces of wire from a phone cable and a bulb out of a flash light.  I remember after a few attempts and re configurations that I worked it out so that I could have it all laid out and manually switch it.  I think somehow I had two different layers of foil separated by a piece of construction paper for an insulator somewhere in there.  It worked well until I stapled it all down to a board so I could take it to school.  I didn't think through the part about stapling through the insulation ...

Wow ... that might have been me :)  I worked there in the late 1970s... such good memories. Small retailers selling components with knowledgeable staff just don't seem to be a thing any longer :/  I was a customer there from age 10 and they gave me my first job at 16/17 selling the components in the front and doing repairs in the back.

Sorry about the necro-post  ;)
