The video features a DIY project where the creator, Hansi, revisits his previous "music reactive desk lamp" project and upgrades it to create a more advanced version. The new project involves creating four floor lamps with LED strips that react to sound and can be wirelessly controlled by a microphone centerpiece. Hansi builds the lamp bases using oak wood and uses a Wemos D1 Mini WiFi board to enable wireless connectivity. He also creates a microphone module with a NodeMCU WiFi module, a battery holder, and a power switch. The lamps can be controlled using a push button, and the system allows for different modes, including a sound-reactive mode. The project is sponsored by ExpressVPN, which is promoted as a service for securing public WiFi connections.
1. Hansi is revisiting a project called the music reactive desk lamp.
2. The project involves creating a room with four floor lamps that react to sound.
3. The lamps are controlled by a portable microphone that transmits sound signals wirelessly.
4. The microphone is connected to a Wi-Fi board that sends data to the lamps.
5. The lamps have individual addressable RGB strips with 144 LEDs per meter.
6. The LEDs can have different colors than their neighbors, allowing for cool light effects.
7. The lamps have a wooden base made from oak.
8. The base is hollow to accommodate the electronics.
9. The electronics include a power supply, a Wi-Fi board, and a perf board.
10. The Wi-Fi board is used to connect the lamps to the microphone.
11. The microphone module includes a battery cell, a battery holder, a power switch, and a Node MCU Wi-Fi module.
12. The Node MCU Wi-Fi module is used to connect the microphone to the Wi-Fi network.
13. The microphone module also includes a charge controller, a push button, and an LED diode.
14. The push button is used to change the lamp mode of operation.
15. The LED diode is used as a status light.
16. The wooden block for the microphone module has a slot for the microphone and the button.
17. The block also has a slot for the charging module.
18. The power circuit is connected to the Wi-Fi board and includes a 10k pull-up resistor.
19. The code for the controller and the lamps is available in the video description.
20. The controller creates a wireless network that the lamps connect to.
21. The controller sends data to the lamps based on the mode it's in.
22. The lamps can show different colors based on the sound data from the microphone.
23. The lamps can also have a static color or fade between different colors.
