Build with Claude kit
Generated render Report
Attendees at Code with Claude (San Francisco, 6 May 2026, then the London and Tokyo extended events) got a maker kit instead of merch: an M5Stack Cardputer ADV pocket computer with a tiny keyboard and screen, a USB-C cable, a lanyard and a card reading 'Have an idea? Bring it to life with Claude Code'. The idea is simple: flash it, hack it, and build your first hardware project with Claude Code. Attendees posted their first Cardputer builds within days.
A programmable pocket computer is swag that asks for a sequel. The card's one-line prompt turns the gift into the start of a project.
What small piece of hardware would your developers actually program, and what's the one sentence that gets them started?
