OFFLINE VOICE CONTROL - MY SMART ROOM

Tech Panda 2026-08-19 | Turn your entire smart room into an **offline voice-controlled automation system using ESP32, Home Assistant, and the DFRobot Gravity DF2301Q Offline Voice Recognition Sensor**.

In this project, I’m using one offline voice module to control devices that were already part of my room
— including **WS2812B wall lights, ceiling lights, ceiling fan speed, my custom ESP32 air purifier, my ESP32-powered smart chair, and my Kenwood air conditioner**.

The main component behind the project is the **DFRobot Gravity: Offline Voice Recognition Sensor — DF2301Q**.

The DF2301Q performs voice recognition locally, so it does not need to send your speech to an online voice assistant just to recognize a command. It includes more than 100 built-in commands and also supports custom command learning, which makes it very useful for ESP32 automation projects.

🔗 **DFRobot Gravity DF2301Q Offline Voice Recognition Sensor:**
dfrobot.com/product-2665.html

In my setup, the DF2301Q recognizes a voice command and sends a command ID to an ESP32. The ESP32 then decides what that command actually means and forwards the required action to the correct system.

For example:

• WS2812B wall lights are controlled through another ESP32 using a local API.
• Ceiling lights and ceiling fan are controlled through Home Assistant.
• My custom-built air purifier uses its own ESP32 controller and local API.
• My smart chair originally had its own built-in voice assistant circuit, but I removed the original electronics and replaced them with an ESP32-based controller. It can now be controlled through Home Assistant and local API commands, including sitting position, comfort mode, lay-down position, massage control, and massage intensity levels.
• My Kenwood air conditioner is connected to Home Assistant through Midea LAN.

This means one tiny offline voice recognition module can control completely different devices and communication systems without needing to understand how each device actually works.

The architecture is simple:

**Voice → DF2301Q → Command ID → ESP32 → Home Assistant / Local API → Smart Device**

One of the most interesting parts of this project is using **custom voice commands and room scenes**.

Instead of saying several individual commands, I can simply say:

**“Work Mode”**

and the system can automatically:

• Turn on the ceiling lights
• Change the WS2812B wall-light scene
• Set the ceiling fan speed
• Adjust the air conditioner
• Control other devices around the room

Or I can say:

**“Movie Mode”**

and completely change the state of the room with a single command.

Because the DF2301Q can learn custom commands, a repeatable sound such as a **finger snap, whistle, or knock** can potentially be mapped to an ESP32 automation command.

The voice recognition itself remains offline. The ESP32 devices can still communicate over the local Wi-Fi network, and locally available Home Assistant integrations can continue working without relying on cloud-based voice recognition.

So this project is not about building another Alexa clone.

It is about creating a dedicated **offline voice interface for ESP32 and Home Assistant**, while keeping the devices and automation systems I already use.

How I Manage Electronic Components | My DIY Inventory System

Tech Panda 2026-08-15 | If you build electronics projects, you probably know the struggle: components everywhere, forgotten sensors, missing resistors, and no idea how many ESP32 boards you actually have.

In this video, I’ll show you the electronics inventory system I use to organize and track my DIY components and projects.

You can manage component types, storage drawers and locations, stock quantities, stock-in and stock-out transactions, project components, low-stock items, component images, and even export complete project component lists as PDF.

I also created a ready-to-use offline version for Windows and Android, so you don’t need a Linux server, cloud service, or complicated setup.

💻 Windows Version: Download from the GitHub link below
📱 Android APK: Download from the GitHub link below
🔑 Default Login: admin / admin

GitHub Link: github.com/arslansadiq87/techpanda-inventory.git

With this system you can:

✅ Organize electronic components
✅ Track exact stock quantities
✅ Record Stock In / Stock Out / Returns / Losses
✅ Store component locations and drawer numbers
✅ Manage components used in DIY projects
✅ Automatically reduce project components from inventory
✅ Track low-stock and out-of-stock parts
✅ Add component images and details
✅ Export project component lists to PDF
✅ Run everything locally and offline

If you have boxes full of ESP32 boards, sensors, ICs, resistors, capacitors, modules, connectors and other electronics, this can make managing your workshop much easier.

I Got 190 Days of ESP32 Battery Life?! BLE vs ESP-NOW Tested

Tech Panda 2026-08-12 | I managed to push an ESP32-C6 Super Mini to an **estimated 190 days of battery life** with a 1000mAh battery model — but the mode that performed best was not the one I expected.

A big thanks to **DFRobot** for providing the Gravity I²C Digital Wattmeter and ESP32-S3 Round Touch Display used in this project.

ESP32-S3 Round Touch Display Development Board (1.85", AI Voice & Wireless Charging)
dfrobot.com/product-2964.html

Gravity: I2C Digital Wattmeter
dfrobot.com/product-1827.html

In this video, I build a complete ESP32 power-testing system and compare multiple operating modes including:

* Active ESP-NOW
* Active BLE
* Deep Sleep + ESP-NOW
* Deep Sleep + BLE
* Frequent Wake + ESP-NOW
* Frequent Wake + BLE
* ESP32-C6 low-power-core modes

To measure the complete test node, I use the **DFRobot Gravity I²C Digital Wattmeter**, while a second ESP32-C6 sends the measurements to a **DFRobot ESP32-S3 Round Touch Display**.

The system measures and displays:

* Instant current
* Average current
* Peak current
* Voltage
* Power
* Energy consumption
* CPU wake count
* Temperature
* Estimated battery runtime

I also built a web dashboard and an automatic self-test mode. With one button, the system runs every power mode for three minutes, records the results, ranks the modes, and predicts the runtime using a 60-second sensor sampling interval.

In my automated test, **Frequent Wake + BLE produced the lowest measured average current**, reaching a predicted runtime of almost **190 days** under the 60-second sampling model.

Important: the 190-day figure is an **estimated runtime based on measured power consumption**, not a completed 190-day battery discharge test. Actual battery life will depend on battery efficiency, regulator losses, temperature, battery condition, and the final hardware design.

I Upgraded My Ultimate ESP32-S3 Automation System

Tech Panda 2026-08-05 | I completely upgrade my previous ESP32 home automation project using JLCPCB.
JLCPCB Flexible Heaters Starting at just $1: flexheater.jlcpcb.com/?from=YKPEXTVXPHFUGCUOQ
and turn it from a hand-wired prototype into a professional all-in-one smart automation controller.

The original version used an 8-channel relay module with relay functions hardcoded inside the firmware. In this upgraded version, I designed my first custom PCB in EasyEDA, expanded the controller to 16 dynamically programmable relay channels, redesigned the complete web dashboard, added industrial communication interfaces, improved the power section, added active cooling, and created a new 3D-printed enclosure.

The complete system is still controlled by a single ESP32-S3.

## Major upgrades in this version

* Custom PCB designed in EasyEDA
* PCB manufactured by JLCPCB
* MCP23017-based 16-channel relay control
* Dynamically programmable relay names and functions
* Manual, pulse, and automatic relay modes
* Sensor-based relay automation
* Individual “Show in Dashboard” option for every relay
* Relay settings saved in external Winbond flash memory
* MAX3485 RS485 communication interface
* SN65HVD232DR CAN communication interface
* Improved XL4061E1-based power section
* 40 mm active cooling fan
* New professional 3D-printed enclosure
* Redesigned tab-based ESP32 web dashboard
* Improved RFID, radar, face-recognition, sound, logging, network, and security settings
* AI agent coding workflow using hundreds of prompts
* Personal electronics inventory-management workflow

## Smart automation features

This controller combines:

* HLK-FM225 face recognition
* RDM6300 RFID access control
* HLK-LD2410B radar presence detection
* PIR motion sensing
* Smoke and air-quality monitoring
* Indoor temperature and humidity monitoring

Built Two-Way ESP32 + Flutter IoT Control Using AI | Ep. 2

Tech Panda 2026-08-03 | In Episode 2 of our Flutter and ESP32 IoT series, we upgrade our project from simple sensor monitoring to a complete two-way communication system using Firebase Realtime Database.

The ESP32-S3 continuously reads the temperature from a BMP280 sensor, displays it on a GC9A01 round display, and uploads the live value to Firebase. At the same time, our Flutter application sends commands back through Firebase to control a two-channel relay module.

This means data can now move in both directions:

ESP32-S3 → Firebase → Flutter App
Flutter App → Firebase → ESP32-S3

The phone and ESP32 do not need to be connected to the same Wi-Fi network. As long as both devices have internet access, you can monitor the temperature and control the hardware from anywhere in the world.

In this episode, you will learn how to:

• Upgrade the existing project from ESP32-C6 to ESP32-S3
• Create a Firebase structure for sensor values and relay states
• Read live temperature data from a BMP280 sensor
• Display temperature on a GC9A01 round display
• Send ESP32 sensor data to Firebase Realtime Database
• Read relay commands from Firebase
• Control two physical relays from a Flutter application
• Synchronize the Flutter web app, Android app, Firebase, and ESP32-S3
• Restore relay states after the ESP32 reconnects
• Test the application using both Wi-Fi and mobile data

Hardware used

ESP32-S3 development board
BMP280 temperature and pressure sensor
GC9A01 round TFT display
Two-channel relay module
Breadboard and jumper wires

ESP32-S3 pin connections

I Built a Live Wi-Fi Packet Monitor with ESP32-S3 | Promiscuous Mode + Wireshark

Tech Panda 2026-07-10 | In this video, I built a live Wi-Fi packet monitor using an ESP32-S3, Python, and Wireshark.

The ESP32-S3 is placed into Wi-Fi promiscuous mode so it can observe nearby Wi-Fi management packets around my own test setup. Then the raw packet data is sent through USB serial to a Python script, converted into PCAP format, and streamed live into Wireshark.

We will look at probe requests, beacon frames, RSSI signal strength, Radiotap headers, and how Wi-Fi devices communicate in the air. This project is for learning, privacy awareness, and understanding how Wi-Fi works.

This is not about stealing data, breaking into networks, or capturing passwords. Use this project only with your own devices, your own network, or in a proper test environment.

A 3D printed ESP32 Filament spool scale

Tech Panda 2026-07-02 | Ever started a long 3D print and wondered: will this filament finish the print or fail halfway?

In this video, I built a smart Wi-Fi filament spool scale using an ESP32 Super Mini, load cell, HX711 amplifier, OLED display, and a fully 3D printed body. This DIY filament weight sensor helps you check the remaining filament before starting a print, so you can avoid failed prints caused by running out of filament.

The complete project was designed as a real working 3D printer upgrade. I created the 3D model, printed the parts, assembled the mechanism, wired the electronics, calibrated the load cell, and added a live web dashboard.

I also used agentic coding / AI-assisted coding to help build the firmware faster, including the ESP32 web server, live weight display, tare function, calibration settings, and saved calibration values.

The ESP32 connects to Wi-Fi and runs a local web dashboard where you can see the live filament weight directly from your browser. It also supports mDNS, so the dashboard can be opened using:

scale.local

The web dashboard includes:

Live filament weight
Tare button
Calibration settings
Saved calibration value
Wi-Fi web access
OLED display support
ESP32 Super Mini control
HX711 load cell reading

01:00 Components List
02:28 Wiring Diagram
03:20 Coding
06:00 Firmware Upload

07:30 Working Scale

The calibration value is saved inside the ESP32 memory, so even after restart or power loss, the scale continues using the saved settings.

This project is useful for 3D printer users who want to know the filament weight before printing, especially for long prints, overnight prints, or almost empty spools.

Can ESP32-S3 Read a USB Flash Drive?

Tech Panda 2026-06-20 | In this video, I tested whether an ESP32-S3 can read a normal USB flash drive directly using its second native USB / OTG port.

Most ESP32 projects use SD cards, SPIFFS, LittleFS, or external flash memory for storage. But ESP32-S3 has native USB support, so I wanted to check if we can connect a USB pendrive directly and read files from it.

In this project, I used the programming / UART USB port for uploading code and serial monitor, and the second native USB / OTG port for connecting the USB flash drive.

The USB drive contains a simple config.txt file, and the ESP32-S3 reads the file and prints the content on the serial monitor.

In this video, I show:

ESP32-S3 dual USB port explanation
UART / COM port vs Native USB / OTG port
USB flash drive connection through OTG
FAT32 USB drive preparation
ESP-IDF USB Mass Storage Host test
Reading config.txt from USB storage
Real hardware test with serial monitor output
Practical use cases for USB storage in ESP32 projects

This can be useful for:

Loading WiFi configuration from USB
Saving sensor logs
Exporting CSV data
Storing RFID or access logs
Loading web dashboard files
Creating removable storage for ESP32-S3 projects

For the first test, use a small FAT32 USB flash drive, preferably 4GB, 8GB, or 16GB. Large USB drives formatted as exFAT or NTFS may not work without extra changes.

Complete source code / ESP-IDF project:
github.com/arslansadiq87/usb-otg-esp32.git

Hardware Used:

ESP32-S3 development board with native USB / OTG port
USB OTG adapter
USB flash drive
USB cable for programming and serial monitor

Software Used:

ESP-IDF
VS Code
Serial Monitor

Next video idea:
Should I make ESP32-S3 save live sensor data directly to USB, or load a complete web dashboard from USB storage?

Stop Running Out of ESP32 Storage! Add Winbond 25Q128 Flash Memory

Tech Panda 2026-06-11 | In this video, I show how to add external flash storage to an ESP32 project using the Winbond 25Q128 SPI flash memory chip.

As ESP32 projects grow, internal storage can become a serious limitation, especially when we need to store web dashboard files, RFID cards, user records, settings, logs, and other permanent data. To solve this, I connected a Winbond 25Q128 flash IC with the ESP32 and integrated it into my existing FM225 facial recognition and RDM6300 RFID access control project.

In this tutorial, you will see how the Winbond flash chip is connected, detected, and used to store web interface files and RFID card data permanently. We also use agentic coding in VS Code with PlatformIO to refactor the project, add Winbond storage support, display storage usage in the web dashboard, and dynamically add or delete RFID cards from the web interface.

This video is mainly about understanding how external SPI flash storage works with ESP32 and how it can make bigger ESP32 projects more powerful and professional.

AI Built ESP32 Desktop Gadget | 3D Printed CCTV, Weather & Clock Dashboard

Tech Panda 2026-05-31 | In this video, I built a smart ESP32 desktop gadget using an ESP32-S3, 2 inch ST7789 TFT display, push buttons, passive buzzer, rechargeable battery module, and a fully 3D printed enclosure.

The interesting part is that I did not write the full firmware manually from scratch. I used AI agentic coding step by step to build the project.

First, I wired the complete hardware.
Then I assembled everything inside the 3D printed case.
After that, I started with small prompts and used Codex/AI agentic coding to generate the firmware feature by feature.

This ESP32 desktop gadget includes:

• Android-like menu interface
• CCTV camera stream
• Weather dashboard
• Clock screen
• Wi-Fi settings
• Buzzer enable/disable option
• Battery percentage indicator
• Four physical navigation buttons
• Passive buzzer feedback
• Rechargeable battery power system
• 3D printed enclosure

This project shows how AI coding agents can be used practically for real ESP32 projects. Instead of asking for the complete code in one prompt, I created the firmware step by step, uploaded it to the ESP32, tested it on real hardware, found issues, and then guided the AI agent again until the project was complete.

ESP32 Cyber Pet with Agentic Coding 🤖 | Round TFT + Mic + Temp Sensor

Tech Panda 2026-05-28 | In this video, I continue from my previous ESP32 round TFT smartwatch project and turn it into a tiny cyber pet.

Last time, we created multiple futuristic watch faces for the GC9A01 round TFT display. This time, we take the same idea further by adding an INMP441 I2S microphone and a BMP280 temperature sensor, so the pet can react to the real world.

This ESP32 cyber pet can:

react to sound using the INMP441 microphone
become surprised when it detects a loud sound
react to temperature using the BMP280 sensor
show hot and cold animations
display time, date, sensor gauges, and cyber-style UI
run smoothly on a 240x240 round TFT display

The most interesting part is that this project was built using agentic coding. We write a detailed prompt, let the AI agent generate the ESP32 PlatformIO code, test it on real hardware, and then keep improving the code until the output works correctly.

If you are new to VS Code, PlatformIO, or agentic coding for ESP32 projects, I have already uploaded a separate beginner tutorial for that. This video focuses on applying that same workflow to a real ESP32 cyber pet project.
