I want to repurpose the casing of an Amazon Echo and an e-ink tablet into two new devices powered by a Raspberry Pi, with Perplexity as the main voice assistant. The work consists of: Designing the internal layout: Raspberry Pi, microphone, and speakers inside the Echo casing, maintaining a clean and stable finish. Creating a wiring diagram, component list, and any required 3D prints or support plates. Setting up the operating system, audio drivers, and Perplexity, including voice activation, speech-to-text (STT), and text-to-speech (TTS). Developing a lightweight graphical interface for a small display (SPI/I²C), capable of showing basic assistant states and brief responses. Automating boot-up so that the device is ready to receive commands on power-up. Replicating the same concept for the e-ink tablet: reuse its casing and integrate the same logic (if the e-ink screen is not viable, it’s enough that the device works via voice). Assemble the prototype for each device. I provide quick feedback and bench testing; I need clear documentation and a ready-to-flash image file for microSD. If you’re experienced with embedded Linux, Python, and Raspberry Pi audio, I look forward to your proposal. If you want, I can also reformat this into a polished freelance job posting in English that would attract Raspberry Pi and embedded Linux developers. Do you want me to do that?
