Biskuit is a compact, ESP32-S3-powered wearable device designed for real-time transcription and effortless note-taking. Featuring a 3-microphone array and wireless communication to sync to to the cloud instantly.

I am trying to design a simpler solution to integrating a Bluetooth board into an iPod classic 5th gen model. Since current aftermarket mods that add Bluetooth require micro-soldering several thin wires to the iPod board, creating a central board that offers enough room to solder flex cables, reminiscent of modern game console mods, is a cleaner and better solution for the future. This project aims at creating the central Bluetooth board for this purpose, the flex cables will be designed and measured out at a later date.

Haptic Glove Controller Board NUCLEO-F411RE based Fixed Servo Connections to match standard servo wiring Revised footprint of 2n3904s transistors since base and emitter footprint were swapped Larger power traces Swapped SDO and SDI of SPI Lines to the FPC connector so it matches with peripheral.

3D Camera Module is a scalable SPI enabled 4 camera array pinout for 3D photogrammetry reconstruction which uses I2C to connect between each module to expand camera capacity while keeping capture sequences in sync. It uses ATMega32U4 with its built in USB 2.0 for data transfer and camera array adjustments and capture as well as a micro SD card slot for local image storage. An interrupt logic pinout should be used on the SPI master module as capture command. Each module is powered via USB-C (5V) or barrel jack (12V regulated to 5V).
