I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. A...

I have six Brax RX2 amplifiers, one Brax DSP, several small electronic accessories and a pair of secondary batteries that all need to live together in a single, cohesive rack inside my vehicle. What I’m after is a complete CAD design that shows exactly how every piece will mount - actual size of each amplifier is 310mm x 200mm x 56 mm Material preference The structure must be a wood frame with acrylic highlights. Design priorities Aesthetics come first. Smooth lines, balanced symmetry around the six identical amps, a tasteful reveal for the DSP, plus discreet compartments or channels for the accessories and batteries so no loose wires are visible once the rack is in place. At the same time, I still need adequate ventilation clearances and service access, so hinges, removable p...

I need a production-ready wake-word model that reliably responds to “Hey Bobo” on both ESP32 and Raspberry Pi boards. Accuracy is critical: in a moderately noisy room it should trigger every time someone clearly says the phrase, yet ignore most unrelated speech. I still want slight phonetic wiggle-room—utterances such as “hello bo,” “hey bebo,” or “hello bebo” should wake the system as well—so fine-tuned threshold settings and a well-balanced dataset will be essential. What I expect from you • A trained wake-word model or firmware that runs in real time on ESP-IDF for ESP32 and on Raspbian/Ubuntu for Raspberry Pi without requiring cloud calls. • Demo code that shows how to load the model, stream audio from an onboar...

The scope covers mechanical layout, locker integration, electronics for inventory control and payment, plus industrial styling that fits a standard retail footprint. Beyond the CAD and schematics, I require a fully costed bill of materials. This means identifying real-world suppliers, part numbers, lead times and unit pricing so we can estimate manufacturing cost at scale and set viability targets. Where multiple component choices exist, highlight the trade-offs (e.g., reliability versus unit price) rather than listing every option. Please include a detailed project proposal that outline...
