Stuart writes that Arduino's reputation collapsed after Qualcomm's acquisition introduced new terms of service requiring a "perpetual, irrevocable license" over user uploads. The maker community, led by Adafruit, initially reacted with outrage, but that anger has since morphed into simple apathy. Despite the company pushing new AI-powered boards and publishing content about agentic AI environments, the platform has become irrelevant in organic conversations.
- Adafruit's "Death of Arduino" graphic went viral on LinkedIn
- New boards include "Arduino Ventuno Q" with on-device processing power
- The author suspects Qualcomm is targeting corporate clients over individual hobbyists
- Competitors like Raspberry Pi Pico and ESP32 boards are gaining traction in the sub-$10 space

Alex-developer writes about a standalone aircraft radar firmware designed for Waveshare ESP32-P4 round touch displays. The system connects to WiFi to fetch live ADS-B traffic, visualizing it on 3.4-inch or 4-inch screens with features like range rings, altitude color coding, airport markers, and weather overlays. It operates independently without needing a Raspberry Pi or an active browser once configured via its built-in admin web page or touch interface.
- Supports both the 720x720 (4") and 800x800 (3.4") Waveshare LCD variants from a single firmware image
- Integrates with multiple data sources including Airplanes.live, ADSB.lol, and local feeds like readsb/dump1090
- Features an optional web-based admin interface for configuration of location, display settings, and WiFi
- Can include aircraft detail popups with PlaneSpotters photo thumbnails via touch input
- Supports optional hardware additions such as a USB GPS receiver or a secondary SSD1306 status OLED

theleestarr writes an open-source ESP32 firmware designed for 1.28″ round displays that functions as a sonar-style radar showing live ADS-B aircraft data around a user's location. The project is compatible with the Waveshare ESP32-S3-LCD-1.28 and can also be used with an ESP32-C3 Super Mini paired with an external GC9A01 display.
- Uses live traffic from adsb.fi
- Features selectable range scales (5, 10, 15, or 25 km) via the BOOT button
- Provides optional runway overlays for major airports
- Includes a sonar-style UI with aircraft symbols, callsigns, and altitude data

Harry Fairhead writes that Zephyr has reached version 1.0 as Arduino's official operating system, a move necessitated by Arm's abandonment of the mbed OS. The Core-Zephyr release supports a range of newer Arduino boards but leaves classic AVR boards, SAMD/SAM boards, Pi Pico, and ESP32 boards on their existing systems, creating a fragmented software landscape. Fairhead notes that Zephyr remains largely invisible to beginners, serving as a background layer that simply enables the traditional Core functions to run.
- The shift was forced by Arm discontinuing mbed, which Fairhead characterizes as typical of chip makers who prioritize hardware over software support.
- Core-Zephyr supports 10 specific boards including the UNO Q, Portenta H7, and Nicla Vision, but not the ESP32 range (which uses Free RTOS) or classic AVR boards.
- Fairhead suggests Arduino could expand Core functions to expose OS-level facilities like multitasking, particularly on boards with IoT coprocessors.

Tim Brookes writes about seven projects you can build with the Cheap Yellow Display (CYD), an affordable ESP32 board with an integrated LCD touch screen that lets you skip soldering and breadboards entirely. The projects span a weather station, a Wi-Fi and Bluetooth penetration testing suite (ESP32 Marauder), a Bluetooth MP3 player, a retro mini TV for videos and games, a Gran Turismo 7 racing dashboard, a Home Assistant music remote, and an ESPHome smart home controller.
- The weather station pulls from both Open-Meteo and OpenWeatherMap and supports a DHT22 sensor for local temperature readings
- The ESP32 Marauder CYD port covers hardware from 1.9-inch non-touch models up to 3.5-inch touch displays
- The retro mini TV is a 3D-printed Simpsons replica combining the Anemoia-ESP32 NES emulator and MiniLegoTV video player
- The GT7 dashboard works because Gran Turismo 7 publishes telemetry over UDP on the local network, a feature shared by other racing simulators
- The CYD Jukebox pairs with Music Assistant to unify local files and streaming services like Apple Music behind one interface

This repository contains a collection of Arduino-based emulators for the vintage Busch 2090 Microtronic Computer System, an educational 4-bit computer from Germany produced in the early 1980s. The project provides multiple implementation versions ranging from simple Arduino Uno R3 setups to more advanced "Next Generation" hardware featuring OLED displays and SD card storage. It includes comprehensive documentation on reverse-engineered protocols such as the 2095 Cassette Interface, machine code sound output techniques, and various built-in ROM programs for games like Lunar Lander and Nim.
