Pictured device is in the hands of "Moana".
Aparently she loves it and the button vibration and neo-pixel lights are fun. We will see how she developes with this device and are standing by ready to update as needed.
The device is currently configured as a basic needs communication device, but first she needs to develop some associations. It is easily updated in python through USB port and / or microSD card.

Under Consideration, Minimum Full Assistive Communication Device
Working name MacD?
Square with large buttons or smaller with rotary encoder?
Rotary Encode can just be smacked for a distress message ...
📏 Overview: The device measures 80mm (3 inches) square and features large 12mm buttons, a compact (likely monochrome) screen, an audio amplifier, and support for a rechargeable battery. It’s designed to work with the Raspberry Pi Pico 2, but is also compatible with the original Pico. It includes connectors for integration into a larger system.

🛠️ Use Cases: Ideal for developers as a development board or as a compact emergency lanyard device.

💸 Estimated Cost: At quantities of 25, the PCB with components and battery is estimated at $25 USD per unit (not including potential tariffs).

🎨 Optional Upgrade: For a few dollars more, a larger color screen could be used. This would require additional space and possibly some redesign.

🎟️ Next Steps: I have some coupons available and I’m considering using them to build this board—unless another project takes priority.
