Episodes run in the order the guides teach. Each one lists the pages it covers, so you can watch it or read it. Click a still to play in place; the player loads only then.
The canvas you draw to - two 576x288 displays, the Even R1 ring and the temple TouchPad, and the phone app that runs your code in a WebView and relays it over Bluetooth. Everything through EP4 runs in the desktop simulator.
Node, the Even Hub CLI, the simulator and the SDK, installed and verified on Mac and Windows. Closes on the two things that cost people an hour later: the EACCES permission error, and the firewall and AP isolation settings that decide whether QR sideload works in EP6.
Signing up at hub.evenrealities.com and getting into the console, plus the detail that bites later: the email you register here has to match the email you use in the Even Realities phone app.
Scaffold a project with the CLI or the minimal template, await the app bridge, define your first text container, and push it live with createStartUpPageContainer. Ends with click and scroll events working, no hardware required.
Firmware updates on fresh hardware, signing into the Even Realities app with your developer email, and finding Prototype Mode in your Even Hub profile. Developer mode is per phone install.
Bind the dev server to your laptop LAN address, set the two Vite keys that make it work, generate a QR with the CLI, and scan it from Prototype Mode. Closes on the four failures worth preempting, including hot reload that works once and dies.
createStartUpPageContainer, textContainerUpgrade for content changes with no flicker, and rebuildPageContainer for layout changes that redraw the whole page. Covers the 20-item list cap, the 12-container budget, and why exactly one container per page carries isEventCapture.
Every gesture, lifecycle signal, IMU sample and audio buffer reaches your app through one callback: bridge.onEvenHubEvent. The four envelopes, the nine event types, and the trap underneath them - the capturing container decides which envelope you receive.
Device info and status subscriptions, choosing between the Even G2 four-mic array and the phone microphone, handling raw 16 kHz PCM, and state that survives a restart. Ends on the mental model everything hangs off - your app is a web app on the phone, and the glasses hold no state at all.
Two independent gates sit between your fetch call and a number on the glasses: the app.json whitelist, then CORS enforcement inside the WebView. Four ways this breaks, a different fix for each, and the curl trick that isolates the cause in seconds.
Authoring white on black in 16 levels of grey that the optics tint green, with one firmware font, no sizes, and black pixels reading as transparent. Hierarchy comes from position and spacing, and border brightness is your only colour control.
Run the reviewer checklist on yourself before you submit. The four ways to run your app and what each exercises, the app.json fields that fail validation, the naming rule that is an automatic reject, and the two checks worth doing by hand.
The whole submission form - uploading the .ehpk, name and tagline, an icon that passes review, simulator screenshots, category and search tags, and the privacy checklist. Closes on approval, resubmission with a version bump, and the publish step that is yours to press.
A bonus episode: add the everything-evenhub marketplace, install the plugin, and describe the app you want in plain language. The scaffold that took fifteen minutes in EP4 takes about thirty seconds.
