Zoe Skyforest writes about Kek, an emulator developed by vanheusden to bring the influential 16-bit PDP-11/70 minicomputer back to life on modern hardware. The software supports a variety of platforms including Linux, Windows, and microcontrollers like the ESP32 or Teensy 4.1.
- Emulates classic disk drives such as RK05, RL02, RP06, and RP07.
- Supports KW11-L line time clocks and DC-11 serial interfaces.
- Capable of running Unix versions from version 5 through version 7 in multi-user mode.
Adam Conway writes about constructing a custom aircraft radar using an ESP32-S3 powered WT32-SC01 Plus display. The device fetches live flight data from ADS-B networks to show real-time positions, altitudes, and routes on a 3.5-inch touchscreen interface. To maintain smooth visuals despite five-second data updates, the system uses dead reckoning to predict aircraft movement between polls.
- Employs an 8-bit parallel bus for high bandwidth display rendering
- Uses Douglas-Peucker simplification to compress coastline data into limited flash memory
- Incorporates emergency squawk code detection with visual warnings
- Manages real-time flight information via the adsb.fi and adsbdb APIs
Jean-Luc Aufranc writes that Seeed Studio’s reTerminal Sticky is a 3.97-inch magnetic touch ePaper display powered by an ESP32-S3 microcontroller. This device can serve as an e-reader, live dashboard, or home automation controller via support for open-source firmware like Crosspoint, TRMNL, and ESPHome. It features a capacitive touchscreen and edge computing capabilities through its built-in microphone.
- 800 x 480 resolution with four levels of grayscale
- Includes temperature/humidity sensors and a 3-axis accelerometer
- Equipped with a 750 mAh battery providing approximately seven days of standby time
- Retails for $49.90
This project implements a retro-style ADS-B radar display designed specifically for the ESP32 using a Cheap Yellow Display (CYD) ILI9341. It fetches aircraft data from local dump1090 instances and visualizes real-time information, including position, altitude, speed, and callsigns, on an interactive radar scope or within a tabular list.
Key features:
* Radar scope visualization featuring range rings, crosshairs, and blips for approaching aircraft.
* A detailed aircraft data table providing quick access to nearby flight info.
* Touchscreen support allowing users to cycle through large radar, split-screen, and full-table layout modes.
* Automatic identification of military aircraft via red color highlighting.
* Highly optimized for MicroPython on ESP32 hardware using specific CYD libraries.
This open-source firmware is designed for the ESP32-C3 Super Mini and a 1.28 inch GC9A01 round display to create a sonar-style aircraft radar. It visualizes live ADS-B data on a circular grid, showing flight paths, detailed aircraft models, altitude, and speed.
- Real-time tracking using adsb.fi for aircraft positions
- Route enrichment through ADSBDB for origin/destination info
- Integrated weather display via Open-Meteo and local time via NTP
- Web-based Wi-Fi setup portal for location and setting configuration
- Support for authenticated OTA firmware updates
Building an affordable Home Assistant dashboard does not require expensive hardware. This guide explores several low-cost methods to create functional control panels and information displays using existing or cheap equipment.
Ways to build a budget dashboard include:
* Repurposing old tablets, phones, or even Kindles from your junk drawer using kiosk browsers or the Home Assistant companion app.
* Purchasing second-hand hardware like older tablets or digital photo frames through online marketplaces.
* Using small ESP32 touchscreen modules for low-power desktop dashboards.
* Implementing E-Ink displays for minimal, always-on information such as weather and calendars.
* Jailbreaking used smart displays to bypass manufacturer limitations and run custom software.
CrowPanel Advanced 10.1-inch HMI Display Overview

* Facial recognition via integrated camera interface
* Voice interaction with microphone array and dual speakers
* Compatible with Arduino IDE, ESP-IDF, and LVGL
ESP-Claw is an AI agent framework by Espressif that enables ESP32 series chips to function as active decision-making centers rather than passive executors. It implements a full intelligence loop involving sensing, reasoning, and execution locally on edge hardware. Through conversational programming via chat interfaces, users can define device behaviors using dynamic Lua loading without traditional coding expertise.
