1. Introduction “Big data analysis has become increasingly indispensable across various scientific and engineering fields. However, dealing with the sheer volume of data often results in slow processing times due to computationally intensive algorithms, such as the 3-D Fourier transform or 3-D prestack migration in geophysics (Yilmaz, 2001). Another challenge arises when the data set […]
1.Background In modern times, there is a growing emphasis on home security. Home security encompasses the combination of security hardware installed on a property and the implementation of personal security practices. The hardware aspect involves doors, locks, alarm systems, lighting, motion detectors, security camera systems, and other protective measures. However, existing home security devices often […]
Since joining the North Temperate Lakes (NTL) LTER site in 2014, I’ve witnessed a growing fascination among many individuals regarding the prospect of creating their own environmental sensors using Arduino or Raspberry Pi as the central computing unit. These devices are notably affordable, typically ranging from $20 to $30, and are much more user-friendly for […]
The Raspberry Pi Super Computer was initially constructed for Oracle Open World in October 2019, featuring 1050 Raspberry Pi 3b+ devices organized in four server racks, forming a large square box resembling a famous British police box from a well-known BBC TV series. However, after the event, the Pi Cluster was eventually discarded as e-waste, […]
“Our company provides a variety of development boards, each with unique power requirements and connectors. While some boards, like the latest Raspberry Pi 4, require a specific input of 5V 3A, others, such as certain Arduino boards, offer more flexibility by accepting a range of voltage inputs (6-20V) and regulating it internally. In addition to […]
In the previous article of the Raspberry Pi Cat Motion Siren project, we focused on deploying .NET applications to the Raspberry Pi using GitHub Actions and Docker. Now that the deployment mechanism is established, it’s time to delve deeper into the application code and Raspberry Pi hardware. This post specifically addresses the process of connecting […]
The DS18B20 temperature sensor is well-suited for various projects such as weather stations and home automation systems. Its ease of setup on the Raspberry Pi makes it particularly convenient. The sensor is compact, similar in size to a transistor, and requires only a single wire for the data signal. Additionally, the DS18B20 sensor offers exceptional […]
Raspberry Pi is a collection of single-board computers that have gained popularity among DIY enthusiasts, hobbyists, and students. These boards were initially developed with the aim of promoting computer science education on a global scale. One key distinction between Arduino and Raspberry Pi is that Arduinos are microcontroller-based boards, whereas Raspberry Pi boards are microprocessor-based […]
In recent times, the popularity of smart home lights has increased due to the growing IoT market. However, these lights are primarily controlled through mobile apps or other devices. More recently, there has been a trend of controlling smart lights using voice commands through AI assistants on phones, speakers, and computers. Despite their convenience, smart […]
While the default configuration of your Raspberry Pi doesn’t support reading analog input, you can enhance its capabilities by utilizing an MCP3008 I/P ADC chip, enabling analog input functionality. By establishing a connection between your Raspberry Pi and an MCP3008 I/P chip, you can leverage the power of SPI to read a maximum of 8 […]
