I still have a copy of Hobby Electronics from 1982 that my dad bought when I was about 9 or so and in primary school, with the article on building Hebot II.

I got various bits and pieces together and experimented with doing things like driving Big Trak gearboxes (remember? J Bull Electrical used to advertise them in every magazine, along with all sorts of fascinating old shite) with an interface plugged into my ZX Spectrum, but I never actually built one.

Funnily enough I was thinking about that the other day, and how sad it is that schools like my son's primary school just have very locked-down iPads for the children to use instead of the BBC Micros we grew up with (I'm guessing you're more approximately my age than primary school age, and those things were in schools well into the early 2000s. Bombproof.) that could be endlessly tinkered with.

Anyway the guy next door does a lot of 3D printing and it's never been easier to draw PCBs and get them made or even etch them at home (it's the drilling bit I hate). So maybe now EBv2.0 is five, it's time to dig out that issue of HE and start transcribing stuff into Kicad and Blender :-)
