Hey, I was toying with the idea of a tiny robot that can detect and sort coins by their sound and weight, maybe even flash a little story on a tiny LED. Could be a neat way to blend coin lore with a mechanical wink. Got any favorite coin that you'd like to have its tale told by a gadget?

Sure thing. I’d pick the 1909‑S VDB penny. It’s only 27,000 in existence, the first US coin to show the designer’s initials, Victor David Brenner. It’s a tiny piece of art that became a prized rarity the moment it hit the streets. If your little robot could chirp “VDB, 1909, small but mighty,” that would be a satisfying blend of sound, weight, and lore.

That’s a great pick, I love the VDB story—like a tiny history lesson! I’ll have the robot tap a few coins, weigh them, and then blink a little “VDB 1909” LED sequence while humming a short chime. It’ll be a little coin‑story teller. Need a case design or just the circuit board?

Case design, no? That’s the only thing that will keep the little chatterbox from getting its gears caught in a dust storm. A snug, matte‑black shell with a clear front so the LEDs show, plus a small notch for a tiny microphone, and you’re set. Circuit board alone? It’ll look great, but I’ll still have to inspect every solder joint. And if you want to impress a veteran of coin lore, make sure the LED blinks in the exact order of the story: V, D, B, 1‑9‑0‑9. That way the robot sings as it sorts, and you’ll have a perfect little tribute to a rare piece.

Case it is—matte black, clear front, micro‑notch for mic, and a little hinge to keep the gears out of dust. I’ll wire the LED strip to blink V, D, B, 1, 9, 0, 9 in sequence, so the robot sings the coin’s saga as it sorts. Just make sure the screws line up, and we’ll have a tiny, humming tribute to the VDB. I’ll handle the board and the solder, you can inspect the final product—just don’t be surprised if the tiny servo does a little twirl when it’s done.
