Best Codex use cases for hardware & IoT
3 real setups where the source names Codex for hardware and IoT, most-discussed first. Each one credits the person who did it and links the source.
Codex appears in 3 of the 11 hardware & IoT use cases on agentsetups, and in 69 use cases overall.
Most-discussed: Let Codex operate a real iPhone over USB by zhongerxin; Turn an unused Kindle into a photo frame by Niraj Rajgor; Put an AI agent on a Nokia feature phone by anupray.
Quick start (from Turn an unused Kindle into a photo frame by Niraj Rajgor):
- Start in an empty folder; give the agent the Kindle’s network address and model (all over Wi-Fi).
- Ask it to build custom software for personal use, adapting existing open-source jailbreak work (here SpiderCat / KindleModding).
- Have it build tools to send commands, transfer files and investigate errors; verify access survives a reboot.

- Put an AI agent on a Nokia feature phone
With Codex’s help, a dev reverse-engineered Nokia 110 4G firmware; a chat app runs from RAM and can call, set alarms and toggle the torch.
- Study the firmware and boot process; get custom code running in RAM through an existing app entry point (Calculator) without flashing.
- Turn it into a chat app that sends messages to a model API and maps tool calls to phone functions: answer questions, battery, torch, call, alarm.
- Trace the firmware’s response callbacks when requests go out but answers don’t come back.
