NxBCI aims to construct an EEG/EMG data collection system that can be used for research, education, and consumer electronic products. The device features 16 channels, each with a resolution of 24 bits and a sampling rate of up to 4 kHz. With a low-noise front-end amplifier, it can achieve an effective resolution of 10 ppm (parts per million) within a measurement range of 3 mVpp, along with a noise characteristic (equivalent input) of less than 1µVpp (0.2 µV RMS). Additionally, the kit includes 2.4G Wi-Fi for data output (TCP or MQTT), Bluetooth for setup control, and access to secondary sensor data. Furthermore, it has a TF slot for offline data collection mode, which is sufficient to support a 24-hour HOLTER mode when configured with a large-capacity lithium battery. The device also features two expansion interfaces (USB-A and 4pin UART/IIC) for connecting external accelerometer-gyroscope-magnetometer components, isolated UART communication modules, and other expansion devices. The USB-Type C interface includes a charging management circuit and programming/debugging port for DIY users to customize extensively.

Our acoustic camera for bird-finding (prototype), a cost-effective and innovative solution designed to help locate and identify birds by their songs in wild areas with high precision. Built upon our advanced multi-channel signal collector, this prototype is ideal for wildlife enthusiasts, researchers, and environmental studies. Our acoustic camera enables users to detect and pinpoint bird species based on their unique vocalizations. Its affordability makes it accessible to hobbyists, students, and institutions, providing a powerful tool for fieldwork without the high cost of traditional equipment. With the ability to record and process multiple sound sources simultaneously, it offers a new way to explore bird populations, monitor biodiversity, and enhance wildlife conservation efforts.

In addition to the acoustic camera, we are excited to announce plans to build an online community for bird observing and photographing enthusiasts, centered around our product. This platform will provide a space for hobbyists, researchers, and wildlife photographers to share their experiences, observations, and photos. Users will be able to discuss bird species identification, share acoustic recordings, and exchange tips on using the acoustic camera for bird-finding in the wild. Our goal is to foster collaboration and knowledge sharing, helping to inspire and support birdwatching and wildlife conservation efforts globally.
