I recall the first time I assembled an AM radio back in 1985. It was exciting because I got to understand the schematic diagram and design my own plastic circuit board (PCB). As long as it meets the demands of the schematic diagram and parts do not criss-cross, then you’re ok.
After board is etched and the parts soldered, you still need batteries to make the radio work.
Maybe it’s time to have one of those wind up radios that gives you 35 minutes of power for every 30 seconds of winding. Save on electricity and be eco-friendly.
