Even G2 SDK font-size workaround: rendering large text as a single image
Quick Learn Coach dev update:
The Even Hub SDK currently does not provide font-size control for TextContainer. G2 uses a fixed firmware font, so changing container dimensions does not make text larger.
My workaround is to render the main concept into a 288×144 canvas, export it as a PNG, and send it through one ImageContainerProperty.
A few lessons from real-device testing:
Sending four image tiles at startup overloaded BLE and disconnected the glasses.
One small image, sent serially after startup, is much more stable.
Avoid frequent image updates and skip unchanged content.
ListContainer is vertical, so a short container may show only the first item.
I replaced the list with gestures: tap for next, swipe up to ask, swipe down to repeat.
I also fixed an auto-switching bug caused by treating undefined system events as clicks. The app now requires an explicit CLICK_EVENT, debounces gestures, and prevents duplicate image renders.
This is still an experimental workaround, but it makes genuinely large, glanceable text possible on G2 without turning the glasses into a dense reading interface. Curious whether anyone has found a better large-text approach using the current SDK.
Controlling the G2 without R1
Quick update: controlling the G2 with phone buttons or other hardware looks possible.
The G2 Bluetooth protocol has already been partly reverse-engineered. The R1 protocol has not, so the simplest route may be:
Phone buttons / Bluetooth remote → phone app → Even Hub → G2
PeKe Labs is already testing a similar controller. I’ll try phone-button control first and share results when I have a working prototype.
I finally got my G2B, and I realized I expected too much from it — so I’m building my own plugins
I finally got my G2B, and within the first few days I realized I had made a classic mistake: I romanticized it a little too much.
Before buying it, I imagined it as an almost magical device — something that could completely change how I interact with AI, learning, work, and everyday life.
After actually using it, reality is a bit more grounded.
The hardware is exciting, and I still think the idea of AI glasses is extremely powerful. But I also realized that the current experience is not as “universal” as I had imagined. There are still many moments where I think: “This could be much better.”
Then I remembered something important:
I’m a developer.
So instead of just waiting for new features, I’ve decided to start building plugins for the Even G2 myself.
My first direction is about learning.
As a student, I’ve been thinking a lot about how AI has changed the relationship between output and understanding. AI can now help us finish assignments, write documents, solve problems, and produce results very quickly. But sometimes the final output looks much better than what we actually understand.
It feels a bit like using a forklift to do work every day, and then forgetting that we still need to train our own body.
Nobody would bring a forklift to the gym. We still go there to build strength ourselves.
But in learning and work, AI sometimes becomes that forklift. It helps us move things, but it can also make us skip the actual training.
So one thing I want to build is a plugin that helps me “catch up” on the things AI helped me finish, but I haven’t truly mastered yet. Almost like a private tutor that quietly appears in my glasses and helps me review, explain, and reinforce knowledge during small moments throughout the day.
The second direction is about information density.
I think AI glasses are especially interesting for people who often feel that the information density of real life is too low. Not because reality is boring, but because sometimes we want a second layer on top of it.
For me, glasses are not about replacing my phone or computer. They are more like a lightweight overlay on reality.
If the glasses only take up a small part of my visual field — maybe 1/4 of it, or even less — then they can quietly open a second line of work or learning without interrupting what I’m already doing in the real world.
That also shapes how I want to design plugins.
I don’t want to fill the glasses with dense text or complicated UI. I want the information to be simple, large, and glanceable. The glasses should support what I’m doing, not fight for all of my attention.
So my design principle is:
Small visual space.
Low interruption.
High-value information.
Learning in the gaps of real life.
I’ll probably start experimenting with learning tools, AI workflows, and lightweight productivity plugins.
If anyone else here is developing for the G2, or if you have ideas for plugins you wish existed, I’d love to hear them.
