I have boxes and boxes of the stuff. Lots of technical sets, 4 Mindstorms sets.
I made my Mrs a robot once, built around an RCX box.

Using a Lego remote control, it had 4 wheel drive, could spin inside it's own radius and the C chanel made it wiggle its eyebrows.

Have built a functioning 4 speed gearbox, also by drilling out the centre of a large gearwheel and using other parts, made a rather bulky but perfectly functional differential. It used to explode if you put too much torque through it, but it was quite satisfying.

Am planning to pass it all on to my 3 year old son at some stage, but all the rubber insulation on the electrical connector cables I have has started perishing. Not sure if I will be able to replace or repair it by the time he's old enough.

I worked out I have over the years spent about £3,000 on it.

TL;DR - fuck Meccano.

Good point.
I might have to rethink things.
