▶ Start the presentation

Project status — 5 November 2026: Rein confirms Roboktober 2026 is complete. Website operational and stable; electronics v4 works and is approved. This is the reviewed presentation package, available for reuse, not an open review request.

Talk for PHP Meetup Groningen, November 5, 2026 (about 47 minutes + questions). Central question: what happens when you push the joystick forward on your phone?

Getting started

The slides, video, and source gallery work offline; no web server is required. External websites and repository links need an internet connection. Hardware toolchains are not included.

Controls

All display assets (including product photos), video, scripts and CSS are local to the package; there are no external fonts or CDN fallbacks. AliExpress and other source links do not load images. Only opening external websites or the page behind the QR code requires internet. Extract the entire package, including vendor/, js/ and img/.

Slide 8 contains a video of Wallie with audio; click play. The video is in Dutch and has no subtitles.
Slide 20 contains the complete public ESP-NOW firmware: eight clicks highlight the code blocks, each with its own explanation alongside (what, why, and effect on the robot); scroll inside the code window for all 205 lines. Revision fb3afa886117, © 2026 wallieonline, GPL-3.0-or-later; the license is included locally. This is not the WebUI source.
Slide 34 covers code in two click steps with exact example results. Slide 35 is then a separate design gallery with 9 click steps, without code. Model names link to the source files in this package's 3dprinter/ folder.
