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

My first circuit was a voltage divider. I turned the theory into practice by taping various (unregulated) voltages off a power supply. My first program was on an TI SR-56 calculator which made a counter, something like: + 1 = DISP GOTO 1 My first job during high school was as in the Children's Shoes Dept at a major department store in Melbourne. My manageress's name was Mrs Shine. Colleagues names were Mrs Springett and Mrs Niblett. In the women's lingerie department next to ours there was one male employee. His name was Mr Strange. I am not kidding - it is true. What's that got to do with electronics? Well as much as I hated that job, Mrs Shine gave me a glowing reference which helped secure my first real job after uni at IBM, and I have been designing circuits ever since. |

Like many people, I started with lantern batteries, hookup wire, bulbs, switches. I was fascinated by how there were two switches in our hallway and either one could always turn the light on or off. I was happy when I figured out how to use two DPDT switches to do that, and then totally proud when I extended the solution to an arbitrary number of switches. Making electromagnets from nails and finer wire came soon after, and then crude buzzers (using bits of hacksaw blade) and relays and motors. My first real "project" was for a primary school play when I was 10. The play involved a UFO and the UFO needed flashing lights. I designed a thing with a short length of broomstick rotated by an electric motor, using an old alarm clock as a reduction gearbox and a rheostat from a model railway set as a speed control, I put drawing pins along the broomstick at different angles and a set of copper fingers touching the drawing pins as the broomstick rotated. The copper fingers were then connected to small bulbs spaced around the circumference of the UFO (big enough for several actors to stand inside it) with coloured cellophane over them. |

A crystal set was my very first circuit, my parents had just bought a big old rambling house and in the attic I found among a lot of other junk a cats whisker crystal still in it's box so I made a radio from it then it was not loud enough so I built an amplifier for it from an old transistor tape recorder of the reel to reel variety and put the whole thing into a cigar box powered by six D cells. I had that radio for years before I got anything better it worked so well I did not need a big antennae. I was 11 when I built it and had the radio into my 20's |

I made my first circuit when i was four. It was a potentiometer, an incandescent bulb and a 9V battery in a cardboard box. :-/O You turn the pot and the bulb got brighter and dimmer. I brought it to the kindergarten the next day to show off. 8) |

Similar to other posts, I started with a Radio Shack 65 in 1 kit. The first circuit was probably the first one in the book. The first one I remember though was a crystal radio. It helped to have a 50KW station 10 miles from the house. |
