Electronics kit for 11 year old

Hi there - my 11 year old son has requested a bundle of general purpose electronics stuff for Christmas.

He is is quite inventive, likes playing with motors (taken out of old toy cars etc) and turning them into other things, and already has a good standard of electronics and programming (html). So I’d say he was closer to intermediate than beginner.

I’ve looked around for a general purpose set of electronic bits and pieces (his granny wants to pay for it!) but I am struggling to find anything that looks quite right. We have about £50 to spend. Can anyone recommend anything? Or suggest a set of components that I could buy individually and package up?



this one has an arduino with it.

another is the adafruit parts pal which is not sold here
