A recent hackathon in Vilnius showcased how AI-assisted development is transforming the traditional coding sprint. The author's team retrofitted a vintage rotary phone with a Raspberry Pi, wiring all its inputs and outputs to a websocket server that controlled everything from audio to the bell ringer. Instead of writing code by hand, they focused on system integration and hardware interfacing.

The demo featured an AI agent powered by the Spotify API that could research and play niche music collections on demand, complete with a Yorkshire gentleman personality voice generated by ElevenLabs. Remarkably, neither team member touched a single line of code over the 48-hour weekend - something that would have been unthinkable just a year ago. This reflects a broader shift where hackathons now emphasize architectural thinking over manual coding.

As software development becomes increasingly AI-assisted, the author argues that traditional web apps no longer represent cutting-edge achievements. Hardware projects now offer the real challenge and excitement that hackathons once provided through pure code. The focus has moved from aching fingers on keyboards to tinkering with physical interfaces and APIs.

They envision a renaissance of retro hardware hacking - turning fax machines into social networks, Game Boy Advances into terminals, or vintage phones into AI-powered music curators. These projects may lack business sense, but they capture the spirit of experimental innovation that makes hackathons compelling.
