The perfect way to impress colleagues during an online meeting.
Jouke Waleson has upgraded an old Dutch telephone from 1950 that he has kept for 15 years. The inventor integrated an ESP32 microcontroller with built-in Wi-Fi and Bluetooth modules into the device.
The developer successfully tested the headset during a Google Meet video conference. One attendee noted the unique sound quality of the device: "I didn’t even realize how much I missed this sound quality! Wonderful. I heard you very clearly, without distortions."
For the project, Waleson installed a new stereo ADCThe ADC (Analog-to-Digital Converter) is a device that converts an analog signal (e.g., sound) into a digital format. and a DAC-decoderThe DAC (Digital-to-Analog Converter) is a device that converts a digital signal back into an analog one.. "I spent two full days setting up the microphone and I2S protocolI2S (Inter-IC Sound) is a serial interface standard for transferring digital audio data between devices.. It would have been impossible without an oscilloscope," he shared.
For those interested in creating something similar, Waleson has shared access to Github for additional inspiration, and has also released a video demonstrating how everything works.
In the video, Waleson turns on the phone, and it starts flashing indicators. He then picks up the handset to showcase the integration with Google Assistant. When asking the assistant about his schedule, Waleson receives responses about his planned events in the calendar. The device can not only connect to other devices via Bluetooth but also functions as a phone, using the numbers on the device itself.
The most practical aspect of this device is perhaps that Waleson plans to place it on the nightstand next to his bed, leaving his smartphone in another room at night.
