One of my first "serious" electronic builds in the 1970s was a variable, current limiting PSU from Heathkit. (Advertised in Practical Electronics). Used that together with a breadboard kit to launch a life long interest in electronics. Still have the PSU in the loft and a handful of old circuits lovingly converted to Veroboard, or homemake PCBs made from copper-clad board etched with ferric chloride (until my mum got the vapours about me "messing around with chemicals" and stopped that route).
