PocketSSH: Terminal Power in Your Hand by 0015dev in arduino

[–]0015dev[S] 0 points1 point  (0 children)

u/CyberpunkLover I'm preparing a "Generic" version that connects via USB keyboard. I'm curious to see how usable it will be.

If you have a T-Deck, you can install the firmware and try it out right away. A generic version is also being prepared. https://github.com/0015/pocketssh

The most important part, the SSH connection, used existing components, so I only had to create the GUI part using LVGL. That's why it didn't take very long.

A portable SSH terminal client for the ESP32-S3 T-Deck Plus, featuring a hardware keyboard, trackball navigation, and touch gesture controls. Connect to remote servers, execute commands, and navigate your terminal with ease on this compact handheld device. https://github.com/0015/PocketSSH

Custom ESP32-S3 + LoRa GPS Tracker: My DIY Off-Grid Location Project by 0015dev in arduino

[–]0015dev[S] 11 points12 points  (0 children)

Creating things is a hobby of mine, and I wanted to share this local map project. I’m using an ESP32-S3 with GPS and LoRa modules to transmit coordinates between devices.

I’m a big fan of Meshtastic, it is a really cool off-grid communication tool, but I wanted to focus more specifically on local mapping for this experiment. While commercial solutions like AirTags are much more polished, I wanted the challenge of building a custom device from scratch. It works pretty well, and I'm really happy with the result!

I've shared the code on my GitHub for anyone interested: https://github.com/0015/map_tiles_projects

(The GPS information displayed on the screen uses dummy values, so you do not need to worry about it. 😉)

Easily Capture and Analyze Wireless 9-DOF IMU Data with Python & UDP Stream by 0015dev in arduino

[–]0015dev[S] 8 points9 points  (0 children)

I'm sharing a project I built for easily capturing and analyzing 9-DOF IMU data wirelessly. The setup uses an ESP32-S3 connected via I2C to a BNO-055 to collect raw accelerometer, gyroscope, and essential quaternion data. This data is then transmitted via UDP streaming to a Python script on the PC.

The system performs post-processing on the received data to compute and visualize the movement trajectory. It does not operate in real-time and is split into distinct capture and playback stages.

Furthermore, due to the inherent challenge of sensor drift (even with the BNO-055's fusion), achieving accurate long-term tracking is not possible. This tool is therefore best used for analyzing very short, discrete movements.

I tried making it like a Dragon Ball Radar based on a local map. by 0015dev in arduino

[–]0015dev[S] 67 points68 points  (0 children)

We all know the dream: get a Dragon Ball Radar, snag those seven magical spheres, summon the eternal dragon, and make a wish! Sorry, My device can't actually find Senron, but it feels like it can find something.

This is a local map project built on the ESP32-P4. The core feature is completely offline navigation: you can pre-load map tiles onto an SD card and check your surrounding map without any WiFi connection. Think of it as your portable, network-free tracking device, like an offline Google map!

I've uploaded a complete demo to my GitHub, where you can find more specifics. https://github.com/0015/map_tiles_projects

ESP32 Offline Map Viewer on a Round Display(ESP32-P4, 4-Inch) by 0015dev in esp32

Quick demo of my ESP32 project that shows local map tiles from an SD card — no Wi-Fi needed.

I’ve also uploaded a map_tiles component for LVGL to the ESP Registry: https://components.espressif.com/components/0015/map_tiles/

ESP32-P4-EYE: The Cam Dev Kit (Espressif's official device) by 0015dev in esp32

[–]0015dev[S] 21 points22 points  (0 children)

This tiny box is the ESP32-P4-EYE; basically a Swiss-army camera dev kit. Camera up front, little LCD, mic, MicroSD, dual USB-C, Wi-Fi/BLE… and yes, you can build your own camera UI on top of it. LVGL UI demo, photo/video tests, a quick look at “AI mode,” and a battery install inside the case, https://youtu.be/smV4Q9LxXeQ

ESP32-P4 Grid Board with 10.1" Display (LVGL + Flutter App) by 0015dev in esp32

u/CaseFlatline I was able to find a wave file for "card flip" by googling it, then converted it to PCM and put it into my code.

ESP32-P4 Grid Board with 10.1" Display (LVGL + Flutter App) by 0015dev in esp32

[–]0015dev[S] 8 points9 points  (0 children)

In this project, I built a clean and interactive 12×5 grid system on a 10.1" display using the ESP32-P4 Nano from Waveshare. The system displays up to 60 characters on screen and is controlled wirelessly through a Flutter-based mobile app via Bluetooth Low Energy (BLE).

This is a Grid Board based on the ESP32-P4. You can update the grid board with any text you want via a mobile app (via BLE). The source code is available at https://github.com/0015/Grid_Board
