This page documents the first step in converting a discontinued Lululemon Smart Mirror into something actually useful again: a generic smart mirror, an AirPlay display, and a general-purpose Linux desktop.

At this point, the Mirror is effectively abandoned hardware. New user accounts can no longer be created, and without an existing login the stock software is unusable. That makes this less of a "mod" and more of a recovery project, the hardware still works, but the original ecosystem around it does not.

This writeup focuses on disassembly and hardware identification. The goal here is twofold: to understand what parts can realistically be reused, and to document enough detail that someone else attempting the same thing doesn't have to start from scratch.

Initial Power-up

Because this unit has never been connected to my Wi-Fi, and Lululemon no longer allows new accounts to be created, this is as far as the stock software will go. The system powers on just fine, and then shows a loading screen while trying to connect to the internet. Sometimes if you wait long enough it will ask for you to connect to it from your phone using a new wifi network that it made, however you still cannot do anything because that requires an account which we don't have.

[more like it would be a shame for this to go to waste especially because of the hardware]. What stood out immediately though is that nothing about the hardware feels dead or locked down, it's the software layer that's abandoned, not the device itself. That distinction ends up shaping most of what follows.

Dissasembly

The rear cover is held on with a series of visible Phillips head screws. Once these are removed, the metal back panel lifts straight up without any adhesive or hidden fasteners.

With the back removed, the internal layout is immediately visible and fairly modular, with everything held in by simple philips head screws and plenty of free space to add additional boards or features.

This openess was unexpected. Nothing in here feels intentionally hostile to repair or reuse, if anything it looks much more like commercial signage hardware rather than a sealed consumer appliance.

Processor

This mirror runs on Andriod OS. Taking a closer look at the mainboard and popping off some shielding cans, we can see that it uses a Qualcomm Snapdragon 410E (APQ 8016E), an ARM Cortex-A53 microprocessor with a max clock speed of 1.2GHz.

Next to it is an unknown IC from Micron labled as 8ZA92 JZ099. My best guess is that it is a Multi Chip Package that has both an LPDDR2/3 and EMMC storage. Above it is a Qualcomm PM8916 Power Management IC.

On the bottom of the board, there is a Qualcomm WCN3660B providing Wifi and bluetooth.

Theres nothing special about these chips but thats kind of the point. These parts are well supported and widely used, not to mention that Qualcomm repeatedly mentions this chip combination in various documentation.

Camera

The camera assembly was interesting to pick apart. The camera is an OmniVision OV5640 (JAL-2721 V3.1). It's 5MP with a maximum image resolution of 2592x1944 which drops to 1080p at 30fps. The wide field of view comes from a simple fisheye lens that's mechanically trapped in place. There's no adhesive or active alignment, the lens is dropped into the housing and constrained by the camera module itself.

I was suprised to see how low-tech the fisheye lens placement was, but it really didnt move around at all once the camera module was screwed down.

Microphone

The microphone board is built around a CX20921 far-field voice input processor and supports a two-microphone array. It connects directly to the mainboard and handles echo cancellation and voice processing locally.

From what I was able to learn about the mirror, I don't think it utilizes any voice commands or even the microphone in any significant capacity. The mirror functions are primarily controlled from your smartphone. Maybe they threw this in with plans for a future update?

Theres also an unused terminal for a usb connection, which could mean that this can be easily (hopefully) connected for audio.

Audio Amp

Audio output is handled by a board based on the TI TPA3116D2, a widely used Class-D amplifier capable of 50W stereo or 100W mono operation.

The speakers used are 2 unlabled downward facing speakers.

Powersupply

The power supply is a dedicated MP118TX unit commonly used in digital signage. After tracking down multiple vendor listings and comparing specifications, it appears capable of supplying:

24V @ 5A

12V @ 5A

5V @ 2A

5V @ 0.5A (standby)

This multirail setup reinforces the impression that this mirror was designed very similar to a digital signage system.

Display Panel

The LCD panel is a Samsung LTI400HN01: a 40" 1920x1080 SVA panel. Unfortunately, this is also the most frustrating part of the entire device.

There are no readily available off-the-shelf controller boards for this panel. Reusing it will almost certainly require a universal LVDS adapter and manual pin remapping, or replacing the panel entirely.

The irony is that everything around the display is remarkably reusable, it's the one component you'd most want to keep that creates the biggest roadblock.

Looking at others tearing down the same panel, it seems like there are 3 possible panels, with mine being the oldest model. The newer panels have readily available controller boards.

The Mirror Itself

Ironically, the best-designed part of the entire product isn't electronic at all. The mirror assembly is a heavy, rigid metal enclosure with a great fit and finish. It feels closer to commercial hardware than consumer electronics.

Even if every internal board were removed, the enclosure alone would be worth repurposing. It's solid, flat, and visually clean, which is exactly what you'd want for a clean smart mirror.
