Would you dig out an old gadget to tinker with it rather than replace it?
A developer known as Infinite-Zombie5875 added ESP-NOW support to a 2009 Sony NW-X1060 Walkman, letting the portable player communicate directly with ESP32 microcontroller devices. The modification is a working demo, shared through an ESP32 community post and project code on GitHub, not a shipped product.
Why it matters
The project shows that a decade-and-a-half-old consumer device's existing Wi-Fi hardware can be repurposed for peer-to-peer microcontroller communication without a hardware swap. It points to a broader pattern in which hobbyists reverse engineer legacy radio firmware to add new connectivity to older gadgets.
The demo uses the Walkman's original Marvell Wi-Fi chip, which was left in place rather than replaced. The developer reverse engineered the radio firmware's receive and transmit paths and added hooks for ESP-NOW action frames plus a native C API on the Walkman side.
The players
Infinite-Zombie5875
An independent hobbyist developer who reverse engineered the Walkman's Wi-Fi firmware to add ESP-NOW support.
Sony
The consumer electronics maker that released the NW-X1060 Walkman in 2009, a portable digital audio player with built-in Wi-Fi.
The details
The Walkman's built-in Marvell Wi-Fi chip normally handles standard wireless networking. ESP-NOW is a lightweight peer-to-peer protocol from Espressif, the maker of the ESP32, that lets devices exchange small messages without a router. The developer reverse engineered the chip's firmware to route ESP-NOW messages through it, so the Walkman can talk directly to ESP32 boards. In the demo, both devices render a shared aquarium scene locally, with state kept in sync over ESP-NOW while an ESP-Mosaico supplies motion data from its inertial measurement unit (IMU), a sensor that tracks orientation and movement.
Timeline
The Sony NW-X1060 Walkman was released in 2009.
The ESP-NOW Walkman project was published on November 2, 2026.
The Tech Race
The project fits a growing hobbyist trend of repurposing legacy consumer hardware, rather than a field-level competitive race among device makers. It stands as a grassroots demonstration, not a milestone tied to any commercial product roadmap.
The modification is a developer demo with no announced availability, pricing, or timeline for general use. Owners of a 2009 Walkman with the same hardware could in principle follow the published project code, but the source does not describe installation steps or the skill required.
The takeaway
The ESP-NOW Walkman shows how existing wireless chips in old consumer gadgets can be reclaimed for new networking roles. Watch the project's GitHub repository for further firmware updates or confirmation of support on other devices.
