I grew up in a technology-driven household, as my dad was an electronics designer from the 1940s through to the 1990s. He still can't leave it alone. He's just bought himself a Taiwanese digital oscilloscope (and is complaining about the quality). I have two excellent scopes he designed in the 1960s and rebuilt from time to time throughout his career. He's 84.
The family saw a range of amazing things when I was a child. I have a photo of Jodrell Bank, taken on holiday, when I was seven or eight. We didn't know how to get there and he and I climbed over lots of gates and waded through (to me) waist-high grass to get near enough. But I printed it myself with his help - it was magic
Other special memories are when he came home with a present for myself and a schoolfriend: a single, red LED each. We were amazed at the "cold" light - no filaments to burn out, hardly any current required - amazing.
I had a holiday job in the factory where he worked in 1975, and remember being allowed to play with one of the first gas* lasers, putting a red dot on the roof beams on the far side of the building - amazing. I remember a "pocket" calculator, with hand-wired circuit boards and little lenses over the digits. It never had a case, and the 'keypad' was a sheet of paper with the numbers written on it. It did square roots, but you had to 'calculate' PI. He used it for years.
We played with shortwave radios, radio controlled models, the first microprocessor kits (Lunar Lander on the Nascom 1, anyone?), and he designed synthesizers and electronic organs commercially for a few years. The neighbours got used to really weird noises drifting out on the summer air (when his south-facing study had to have the windows open). Want to talk like a Dalek? We could!
There was always something new and unusual at home, either to play with or _not_ to play with! In the winter of three-day-weeks, we stayed warm, as he built an inverter to run the gas boiler during the power cuts, coupled with a string of 12V car bulbs for light. He gave me the latest version last week-end ("in case you need it"), complete with extra hand-wound coils on the toroidal transformer.
There's a lot more, but the technology moment that really stands out is those LEDs. I was only about ten or eleven, and Armstrong and Aldrin had come back from the moon a year earlier, but it was those little red lights that made me realise that high-technology really could change the everyday world as I understood it. And it has.

*gas, I think - it might have been ruby. We tried to make it go the following summer, but it hadn't been used in the interim and wouldn't lase any more.
