I've identified several prominent DIY electronics magazines from the early 1980s in the US. The most promising candidates, based on the user's description, are 'Popular Electronics' and 'Byte'. 'Popular Electronics' was a highly circulated magazine that even inspired the founding of Microsoft, and it transitioned into 'Computers & Electronics' in 1982. 'Byte' was a leading computer magazine that often featured electronics content and was known for its distinctive cover art by Robert Tinney. Other magazines like 'Radio Electronics Magazine', 'Nuts and Volts', 'Elektor Electronics Magazine', 'Practical Electronics', 'Circuit Cellar', 'Silicon Chip Magazine', and 'Hobby Electronics' were also noted, but 'Popular Electronics' and 'Byte' seem to be the strongest fits for the US context and time frame.
