Badger 2040 W e-Paper display gets WiFi & Bluetooth with Raspberry Pi Pico W
It is an update to the Pimoroni Badger 2040 with the exact same display, but instead of using a Raspberry Pi RP2040 microcontroller, Pimoroni fitted a Raspberry Pi Pico W on the back of the board, probably to avoid going through FCC and CE certifications. Badger 2040 W specifications: MCU board – Raspberry Pi Pico W board with: Raspberry Pi RP2040 dual-core Arm Cortex M0+ running at up to 133Mhz with 264kB of SRAM Storage...

Monitoring hospital bed occupancy with an Arduino Nano 33 BLE Sense
In care facilities and hospitals, being able to tell when beds are occupied or free is vital knowledge for the staff, as they can move onto other tasks more quickly with up-to-date information. Adam Milton-Barker’s hospital bed occupancy detection system aims to accomplish this goal by combining embedded machine learning models and connected hardware for gathering real-time data.
Milton-Barker’s first step was to create a new Edge Impulse project and add several samples of himself either getting into bed for an occupied status or standing up to indicate a vacancy by taking continuous measurements from a Nano 33 BLE Sense’s built-in accelerometer, gyroscope, and magnetometer. Once passed through a spectral analysis block, the resulting nine-channel data was used to train a classification model that could accurately detect when a person either gets in or out of bed, or for a lack of general activity.
