 You can build a custom neon-like sign using LED noodles from Adafruit. We designed and 3D printed a neon sign for the downtown LEGO shop creator set from LEGO. It features three different LED noodles that are press-fitted in shape like a noodle, a bowl, and a set of chopsticks. The glowing sign adds a nighttime vibe that we think is perfect for the downtown noodle shop. We designed this to use the whole length of the LED noodles so they're fully utilized. Start by building your preferred play set. We chose the two-floor version with an apartment and roof terrace. The wires are cleverly routed behind the sign and press-fitted into channels to keep them hidden. The LED noodles are wired in parallel and share power and ground connections to make the routing in line with the shapes. The sign features a built-in LEGO compatible mount that can snap onto existing LEGO plates. The coin-sealed battery holder fits inside the apartment and the wiring goes through the roof doorway. The battery holder features a built-in slide switch so it can be turned on and off. We really like this version because it can open and close so you can get to the battery holder. We hope this inspires you to use Adafruit LED noodles for your next miniature build.
