When I was young maybe 4, whenever I went to someone house I would end up flicking on and off the light switch for an hour and by the age 5 I would take anything I found apart. My first electronics project was connecting a Rc car remote to a telephone so it would drive around when the phone rang. At age 6 I got really lucky and found a robotics course that was actually robotics and not Lego mindstorm , where I learned to solder and basic electronics. but sadly my teacher moved to hong kong.
It disappoints me how pitiful science is in school. are grade 6 electronics unit was horrible, making a lemon battery and turning on a light bulb, thankfully the teacher let me teach some of it:). Today it is impossible to find a robotics course for anyone under 15, even an electronics kit is so scarce.
I'm glad that my generation has likely the most important invention ever, the internet or I wouldn't know 95% of the stuff that I currently do.

I used to see how fast I could get the electricity meter to spin by turning on as much as possible at the same time.
Re. your other points though I was at the Maker Faire in Newcastle (UK) at the weekend and it looked to me like electronics as a hobby is making a major comeback and there was plenty of educational material/kits available. Hopefully the Maker Faire concept will spread over here (I would like one in the South of England). The teaching of electronics in school may be crap (I don't know if it is as I was school a LONG time ago) but there's plenty of resources out there for people who are interested to teach themselves. Electronics teaching was non-existent when I was at school (beyond perhaps ohms law in Physics) so I am completely self taught.

I've been to active surplus wich is great but they sell mostly larger analog components and not many IC's or micro controllers. I did stumble on another store's website but I cant seem to find it any more. I't would be great to know more

the steeles one is probably bigger the downtown location used to have a basement. lately the prices have been going up but there still reasonable. they do have some good HV stuff, there's some transformer but not that powerful. they did have some caps and stuff . if youwant a relly good place to get HV stuff then go here http://a1parts.com/ They have some good hv transformers but It's very very surplus

When I was at school in the early to middle '70s, we had an electronics club. I, together with 2 others, built a complete auto-tracking slow-scan weather satellite tracking station. The tracking was controlled by punch tapes produced by a PDP11/45 running RSTS/E in the school computer lab which produced a tape for right ascension and another for declination. These were calculated for a specific night, time & satellite transition. A timer stepped the tape through readers stolen from a pair of otherwise dead ASR 33 teletypes which controlled the tracking motors.
We designed and built the whole thing from scratch, including building the low-noise front ends, designing & constructing the parabolic reflectors (bending & welding etc.), modifying an old B&W TV etc. with help from the British Astronomical Association.
So, some schools at least in the UK even in the mid '70s were doing decent electronics. I also remember making an electronic timer with optical finish line for the school track and a bunch of other stuff, including making a cast phosphor bronze direct drive turntable with unipivot arm which I still have parts of. The box was made from Iroko and the top from brushed & anodised Al. Amazing to think that anyone thought brushed aluminium was cool, but in those days we did...

At my high school, the best thing we can make is a digital clock with 7 segment and counters, a D/A converter and a FM transmitter. which i have all done before......
