Long before webcams became background furniture, a group at the University of Cambridge pointed a camera at a coffee pot because walking down the hall to find an empty pot was apparently too much wasted effort.
Visit the Trojan Room Coffee Machine page
The page that survives is wonderfully matter-of-fact about the whole thing. A video capture board in an Acorn Archimedes grabbed one frame every second. The machine JPEG-encoded the image, and the Web server requested frames through an RPC mechanism developed in the Computer Laboratory.
The coffee pot itself was already being watched before Cambridge had a World Wide Web server. Once the Web arrived, the local convenience hack became something much larger: people outside the building could check the status of a coffee machine they could not possibly drink from.
That is early Web culture in miniature.
A useful problem came first
Nobody started with a marketing plan for “live streaming.” There was coffee in another room. People wanted to know whether there was any left. A camera and network connection solved it.
The surviving page still explains the technical plumbing instead of polishing the story into legend. It mentions MSRPC2, MSNL, the Acorn Archimedes, JPEG encoding, and even the fact that the lights in the Trojan Room were not always switched on.
In November 1994, BBC Radio Cambridgeshire visited to report on the service. The lab did what a lab full of networked computers in 1994 would naturally do: connected a radio to a workstation, relayed the broadcast across the local network, recorded it digitally, and put that online too.
For a webmaster in 2026, the page is a nice reminder that memorable Web projects often begin with an extremely specific problem. The technology serves the thing. The thing does not exist merely to justify a technology stack.
This site came from the larger corpus we are working through for CacheRat’s Ancient Web project. The full list contains 1,967 old, technical, personal, institutional, and generally strange corners of the Web.

The original coffee machine is no longer dispensing status reports to the Internet, but Cambridge kept the page and the explanation.
