8BitFlux has launched the 8-bit Workbench, a platform for educational experiments with eight-bit systems. It features LEDs, toggle switches, and can be expanded to 16-bit functionality.
An introduction to the ESP32 microcontroller for IoT projects, covering MicroPython and Arduino IDE programming.
This project details building a small interactive desktop 'pet' using an Xiao ESP32 S3 microcontroller, a 0.9-inch OLED display, and a 3D printed case created with JUSTWAY.
ESPConnect is a web-based tool for flashing, inspecting, and managing the filesystem of ESP32 boards, offering a simplified alternative to traditional IDEs.
Adafruit and the maker community are criticizing Qualcomm's new terms of service for Arduino, citing concerns about user data, reverse-engineering restrictions, and a departure from open-hardware principles. The article also details the history of Arduino and its origins in the Wiring project.
The Adafruit Feather Bluefruit Sense takes the popular Feather nRF52840 Express and adds a comprehensive set of sensors, making it an excellent wireless sensor platform with Bluetooth Low Energy, native USB support, and Arduino/CircuitPython compatibility. It features environmental and motion sensing capabilities including 9-DoF motion sensors, proximity/light/color/gesture sensor, PDM microphone, humidity sensor, and barometric pressure sensor.
Jeff Geerling reviews the Arduino Uno Q, a Qualcomm-powered board that blends microcontroller and SBC functionality. He explores its hardware, performance, software (App Lab), and potential applications, finding it to be a unique but somewhat awkward offering in the SBC market.
This article explores TinyML, a branch of machine learning run on microcontrollers like the ESP32. It details how TinyML can be used for local inference, anomaly detection, and efficient data processing with minimal power consumption, using an example of temperature and humidity monitoring.
Arduino and Qualcomm Technologies are joining forces to deliver more powerful technology for makers, entrepreneurs, educators, and professionals. This partnership will scale Arduino’s vision with Qualcomm’s silicon, AI, graphics, and processing capabilities, while maintaining Arduino’s commitment to openness and community.
Paris-based Open Tools is developing an open-source inkjet printer that uses standard mechanical components and refillable ink cartridges, controlled by a Raspberry Pi Zero W. It can print on both sheets and rolls of paper, automatically cutting the latter to size, and aims to provide a repairable, upgradeable alternative to traditional printers.
