Macintosh emulator works on ESP32-P4 display devkits from M5Stack and Waveshare

ESP32 chips have been used for retro gaming and computing for years, but Austin McChord (Amcchord) adds to that with a Macintosh emulator ported to a couple of ESP32-P4 display devkits. His project is a full port of the BasiliskII Macintosh 68k emulator, bringing classic Mac OS (System 7.x through Mac OS 8.1) to portable ESP32-P4 embedded devices with touchscreen, USB peripherals, and WiFi support through an ESP32-C6 on the boards. The main development platform appears to be the M5Stack Tab5 equipped with a 5-inch touchscreen display with 1280×720 resolution. However, if you need something with a larger screen, the Waveshare ESP32-P4-WIFI6-Touch-LCD-10.1 is also supported, and features a 10.1-inch display with 1280×800 resolution and a 10-point capacitive touchscreen. The actual Mac OS resolutions used are 640×360 and 640×400, respectively, then scaled twice to the native resolution of the display. Highlights of the project: CPU – Motorola 68040 emulation with FPU (68881) […]

BIGTREETECH Panda Sense Pro 8-in-1 smart air quality monitor works with Home Assistant and Klipper for 3D printers

BIGTREETECH Panda Sense Pro 8-in-1 Air Quality Monitor for 3D Printers

BIGTREETECH (BIQU) has introduced the BIQU Panda Sense Pro, an 8-in-1 smart air quality monitor designed for 3D printing environments such as home workshops, maker spaces, and print farms. It continuously measures airborne particles, gases, temperature, and humidity, helping users monitor indoor air quality while printing. The device also integrates with Klipper-based printers and smart home platforms, making it suitable for both standalone monitoring and automated environmental control. It combines laser particle, NDIR CO₂, and electrochemical formaldehyde sensors to monitor PM2.5, PM10, CO₂, HCHO, eTVOC, AQI, temperature, and humidity in real time. The monitor features a 3.5-inch 480×320 TFT display, 2.4 GHz Wi-Fi with MQTT, USB Type-C power, 24-hour and 30-day data logging, and upcoming app-based remote monitoring. It integrates with Moonraker (Fluidd/Mainsail) and Home Assistant for automation, such as controlling fans or air purifiers based on sensor readings. The enclosure files are open-source, which means you can customize and […]

ESP32-C5 dual-band WiFi 6 and Bluetooth LE IoT board features 1.47-inch color LCD

We’ve covered plenty of connected displays based on ESP32 chips over the years, but the Waveshare ESP32-C5-LCD-1.47 is a little different, since it’s the first to feature an ESP32-C5 chip for dual-band WiFi 6 connectivity. It’s basically based on the ESP32-C6-LCD-1.47 design, but replaces the ESP32-C6 supporting 2.4 GHz WiFi 6 with an ESP32-C5 capable of handling both 2.4 GHz and 5 GHz WiFi 6. Other features mostly remain the same: a 1.47-inch 262K-color display with 320 x 172 resolution, 4MB of flash, an RGB LED, a microSD card slot, and two 9-pin headers for GPIO expansion. Waveshare ESP32-C5-LCD-1.47 specifications: Wireless MCU – Espressif Systems ESP32-C5FH4 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip Storage – 320 KB ROM, 4MB flash Wireless Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi […]

PaperBoy Game Boy Emulator works at 60 FPS on ESP32-S3 E Ink devkit

PaperBoy E Ink ESP32-S3 Gameboy emulator

60 FPS gaming on an E Ink display? That doesn’t seem right… But that’s exactly what Wenting Zhang’s PaperBoy Game Boy emulator project does, using the M5Stack PaperS3 devkit, pairing an ESP32-S3 wireless microcontroller with a 4.7-inch E Ink display with 960 x 540 resolution. One of the tricks here is that the bottom part of the ePaper touchscreen display is used for control buttons and doesn’t need to be refreshed, while the active part only requires 160 x 144 resolution, scaled three times to represent various shades of grey. Contrary to most small Eink devkits, the PaperS3 features a screen with a raw row/column driver interface, which enabled him to drive the display while bypassing the normal waveform method, and deliver a higher refresh rate up to 60 FPS. Wenting didn’t reinvent the wheel for the Game Boy emulation part, and after testing three different emulators, he went with […]
