ALT Slide 1 of 4: Google Open Source card with a blue pill badge reading "OCTOBER 1 • 101 KEYBOARD DAY". Headline: "Looks Like a 10/1 Joke. Built as Real Open-Source Hardware." Subtitle: "Every October 1st (10/1 = 101-key keyboard), Google Japan's Gboard team unveils a satirical physical keyboard—and open-sources the complete CAD, PCB, and firmware files so anyone can actually build it." Below is a photo of a person pressing a single key at the end of a motorized four-lane desktop conveyor belt keyboard while 3D-printed key tiles circulate like a conveyor-belt sushi restaurant. Footer: Google Open Source logo, opensource.googleblog.com, and "Swipe -> 1 / 4".
ALT Slide 2 of 4: Dark-mode hardware specification card with a green badge reading "MOZC-CONVEYORBELT • APACHE-2.0". Headline: "Rotating Keys. Real Schematics." Three stacked specification cards read: 1) "116 Choc V1 Switches (29 / Belt)" — "Four motorized conveyor belts rotate keys to a single pressing zone at the right edge—reducing left-right finger travel to zero." 2) "18 STL Files (157 Printed Parts)" — "3D-printable gears, belt links, frames, and magnetic key tiles alongside 3 custom KiCad PCB schematics (main, reflection, and sensor boards)." 3) "ATOMS3 Lite + DRV8833 + 150RPM Motor" — "Powered by an ESP32-S3 controller, dual H-bridge motor driver, N20 worm gear motor, and 568 miniature bearings." Footer: "2 / 4".
ALT Slide 3 of 4: Light-mode card with a blue badge reading "GOOGLE/MOZC-DEVICES ARCHIVE". Headline: "A Decade of Open-Source Hardware". Top callout banner: "WHAT IS 10/1 KEYBOARD DAY? — October 1 writes out as '10/1'—a nod to the traditional 101-key layout. Every year reside in google/mozc-devices alongside the 2026 Conveyor Belt:" A 2x2 grid lists four previous open-source releases: "2025 • Dial Version (Rotary dial keyboards with multiple concentric drums)", "2024 • Double-Sided Version (360-degree toroidal mobius strip keyboard with front and back keys)", "2023 • Caps Lock Hat (Wearable keycap hat using an inertial sensor for head-turn selection and push-down typing)", and "2022 • Bar & 2021 • Teacup (Single-row 1.6-meter stick keyboard and cylindrical Yunomi teacup)". Footer: "3 / 4".
ALT Slide 4 of 4: Google Open Source call-to-action card with a yellow badge reading "BUILD IT YOURSELF". Headline: "Print the Belts. Flash the Firmware." Subtitle: "Complete English & Japanese build guide, bill of materials, KiCad PCBs, 3D-printable STLs, and PlatformIO firmware." An exploded technical diagram shows the 3D-printed conveyor belt links, gears, N20 motor mount, and PCB assembly. A collaborator badge credits "@googlejapan Gboard Team (google/mozc-devices) • Apache-2.0 Hardware & Firmware". A dark navy call-to-action banner at the bottom reads: "Explore the Schematics & Build Guide: github.com/google/mozc-devices — ↓ First reply below". Footer: Google Open Source logo, @GoogleOSS, and "4 / 4".
