Maker Builds PAL 8000 Air Monitor
On April 2, 2026, a maker published PAL 8000, a HAL 9000–inspired personal room air quality bot built with a Raspberry Pi Pico W, Sensirion SGP40 VOC sensor, DFPlayer audio module, and ElevenLabs-generated voice clips. The device maps VOC index (0–500) to progressive prerecorded warnings, offers a local web app for real-time monitoring, and uses a 3D-printed HAL-like enclosure.
