OPEN HARDWARE, SECOND LIVES
From idle speakers and old Kindles to service-dependent robots and unsupported printers. Find a route for the device you own, then check compatibility before getting started.
Find your device ↓How we review evidence ↗START WITH YOUR DEVICE
Home Assistant, WHOOP and desktop usage dashboards need different external services. An e-ink display endpoint is not evidence of AI running locally.
Compare requirements and routes ↗02 / ROUTE COMPARISONDecide whether you accept vendor-cloud dependence, disassembly and an external host before choosing a route for your speaker.
Compare requirements and routes ↗03 / ROUTE COMPARISONChoose one clear job, then check boot mode, storage health and backups. Installing an OS does not add computing power.
Compare requirements and routes ↗Narrow by device, then check model, firmware and recovery requirements.
E1 = source and deployment docs reviewed · E2 = author hardware claim or demonstration · No E3 independent reproduction. Difficulty is editorial judgment; prices are unknown.
Connect an existing XiaoAI speaker to a language model while retaining its voice input.
Device scopeXiaomi XiaoAI speakers; the README uses LX06. Check the hardware parameter for other models.

Check audio drivers, architecture and server capabilities for each device.
Provide an alternative OS for selected Android phones and tablets whose vendor updates have ended.

This repository is the Linux client; it does not establish that the entire mobile app is open source. Check the battery before continuous charging.
Turn an old tablet into an auxiliary display endpoint receiving desktop sharing in a browser.
Device scopeOld tablets, phones or computers with a compatible modern browser.
An independently extended desktop usually also needs a virtual display adapter. Very old browsers may not work.

Check external-media boot first. The enclosure brand or SoC alone does not establish support.
Turn selected idle TV boxes into lightweight Linux service hosts.
Device scopeBoxes/development boards and exact SoC/DTB combinations in the project's support table.
Community adaptation is not official Armbian support. eMMC installation is riskier than external boot.
Provide community app installation and management on an owner's webOS TV.
Device scopeLG webOS TVs meeting root prerequisites.
Depends on privilege access/development environments available for the exact firmware. This does not repair physical TV faults.
Preserve a historical route for running homebrew on old webOS TVs.

Not all robots are supported. Rooting and recovery difficulty vary by model.
Reuse Vector robots with community voice services and optional knowledge-question backends.

Check UART, backup and flashing instructions for the exact board.
Replace firmware on selected smart plugs, lights and sensors to regain local control.

Confirm chip, pins, calibration data and flashing method for every board.
Reconfigure programmable old sensors, plugs and DIY boards for local uses.
