Vehicle LED VMS Display Design

I need a compact, vehicle-mounted LED VMS that fits inside a 100 × 30 × 30 form factor—or slimmer if you can manage it—while still giving me bright, readable messaging in traffic. The unit must handle animated text as well as directional graphics, using changeable LEDs or a full matrix RGB setup so I can swap colours on demand. Core messages and symbols the board must cycle through: • “UNFALL”, “GESPERRT”, “ÖL SPUR”, “BITTE FOLGEN”, “STOP” • Animated arrows: left, right, and a dual arrow that grows out from the middle For reference, the overall behaviour should look similar to the product shown in this short clip: https://youtu.be/rscdvdXRs78?is=az5r5EqMB_KctveK I’ll supply the exact word list and arrow timings once we start; what I need from you is the complete working package—electronics design, firmware, and a simple control interface (web, app, or handheld keypad, your choice) that lets me push new messages or trigger one-touch presets. Deliverables 1. Circuit and PCB files for the LED matrix, driver, and controller 2. Firmware with animated text and arrow routines pre-programmed 3. Control interface source and build instructions 4. Mechanical drawings that prove the assembly stays within 100 × 30 × 30 5. A short demo video or simulation confirming brightness and animation speed Acceptance criteria • All listed texts and arrows animate smoothly and legibly at typical roadside distances • Colour changes are selectable per message • Brightness is daylight-visible yet dimmable for night use • No dimension exceeds the stated envelope once the housing is fitted If you have experience with vehicle VMS boards, CAN bus, or low-power RGB matrices, let’s get this on the road.
