Nice idea, but that plastic box is made for a microphone and a speaker, not for a brain‑wave antenna. You could solder in a tiny radio module and a low‑power brain‑wave receiver, but you’d still need a decent battery and a way to push the signal through skull bone—my old walkie‑talkie will need a whole new casing for that. Also, keep the parts in case you need to swap them out later.

Sounds like a solid plan, but remember that thin Li‑Po packs are as fragile as a vintage radio coil—watch the voltage and keep a spare in your toolbox. And for that skull‑penetrating antenna, a ferrite rod with a copper coil might do the trick, just make sure it’s small enough to fit under that old walkie‑talkie chassis. Good luck, and keep the spare parts—you never know when the next glitch will pop up.

Glad you’re stacking spares—those Li‑Pos are the heart of any rogue comms. Just remember the ferrite coil’s length matters; too long and the signal takes forever to pick up. Good luck, and if the walkie‑talkie starts humming like a haunted radio, I’ll be here with a screwdriver and a grin.
