Christian Cawley listicled 10 old devices upcycled to house a Raspberry Pi (including the Tomy toy dashboard OutRun previously at BB).
Embedded above is a Pi, with a wee LCD monitor, embedded in a 1975 mini TV by Martin Mander. Perfection!
This is a Hitachi I-89-311 portable TV that I've converted into a retro wall-mounted information station! It displays useful content in a series of full-screen Chrome tabs, and turning the TV's tuning dial switches between the pages. The volume button controls scrolling, the on-off button refreshes the page, and the TV has a PIR motion sensor so it turns off when you walk away.
