Sounds like a solid plan. Scavenged radio parts give you a raw canvas and a decent price tag. The real work is getting the transformer to spit the right voltage, soldering the right resistors, and making sure the oscillator doesn’t die in the first week. If you’re in it for the grind, that’s where the fun’s at. But if you expect instant rave gear, you’re asking for a disappointment. Stick with the hands‑on, and you’ll get something that actually works.
