Optional features (welcome): -Ability to turn on the computer via WiFi network / mobile app (e.g., local web page or Blynk app). -Bluetooth as an alternative communication method. - Additional mobile-use button (touch or physical). Design & Physical Requirements: -Premium design – golf theme + SIM GOLF logo (to be provided) -Elegant enclosure – can be 3D printed, made of aluminum, or other durable material -Preferred color: dark, with LED backlighting (e.g., around the button) -Button dimensions:Base: approx. 10x10 cm, Height: any – proportional and elegant Stability: -Can be placed on a desk or wall-mounted (e.g., mounting holes) -Rubber feet to prevent slipping -LED Lighting: - Must be visible in a dark room – can be a subtle glow or halo light around the button Additional Notes: - Small production series required (e.g., 3–10 units initially) - I expect a complete, ready-to-use set: Ready-to-connect buttons Computer module (with relay) Code (if programming is required) Simple installation and usage manual
