While the must-have is interactive touch, I’m open to recommendations on optional extras—wireless connectivity or even a 4 K optical block—so feel free to flag those if they strengthen the overall design. I’ll review progress in logical milestones: concept, detailed design, prototype, final refinements. Once each stage meets the agreed acceptance tests (touch accuracy within ±2 mm across the screen, minimum 3 000 lumens real-world...

I have an idea for a two-way text-messaging gadget that is no larger than a common correction-tape dispenser. The brain of the unit must be an ESP32-C3 and the only wireless link I need is Wi-Fi—no Bluetooth fallback.
