Popfold for iPhone Duo: close it and it's a photo card. Open it and the people in your photo stand up out of the fold.

Your own photos, cut out on-device. Shipping for Duo launch.

Building a pop-up card app for iPhone Duo aiming to ship at launch.

Pick a photo, open the phone, and the people stand up out of the fold.

This is the regular-iPhone version with a slider. On Duo, the hinge does it.

Built with @JolinJiao on @bitrig

Got to chat with @Alfred_Lin today after the talk about robotics evaluation.
Really grateful for his time and perspective, especially on the qualities of a good founder.

Spend the morning at Circuit Launch Beer Review, thanks for the wonderful event @circuitlaunch @DhruvDiddi @Shermzeee

@wongmjane We need Waymo in sfo

[Li Junyi (LJ) @lj_ships]

@viditb Which one you chose at the end?

[Li Junyi (LJ) @lj_ships]

@bradflora @kimmaicutler @bitrig That was so memorable

Day 1 of #VASTBuildersChallenge in SF. We're Grabbit Mining Co. 🐰⛏️
mining 2,352 indexed video clips for the near-misses robotics teams need: forklift turning into a worker, person 2m from a moving vehicle.

AI flags, a human confirms. Building on @VAST_Data + @nvidia Cosmos, @CoreWeave, @weights_biases, @cursor_ai with @JolinJiao

Hack energy: one arm to teach, one arm to copy, and two laptops that have to agree before either moves.

Flower Hand @ the @flwrlabs Collaborative Agent Hackathon, w/ @JolinJiao

[Li Junyi (LJ) @lj_ships]

@viditb So happy to see that!

[Li Junyi (LJ) @lj_ships]

Other half of our build at the @flwrlabs hackathon: an order just went cloud to Flower SuperGrid to my laptop’s Safety node and got approved.

Next step is her laptop becoming the Pharmacy node, and the arm only moves when both keys turn.

[KJ @JolinJiao]

Everyone else at this agent hackathon brought laptops.
We brought two robot arms. 🦾🦾

Collaborative agents, but make it physical.

@flwrlabs @Stanford @lj_ships

[Li Junyi (LJ) @lj_ships]

At the Collaborative Agent Hackathon @ Stanford with @flwrlabs today, with a $400 robot arm in my bag.

Ready to build.

[Li Junyi (LJ) @lj_ships]

@kylemacomber @_julianschiavo @bitrig It helped our team a ton during the bitrig hackathon. I’m switching to bitrig for sure.

[Li Junyi (LJ) @lj_ships]

@viditb @bitrig It nice nice meeting you man, duo-man is just soooo good. Looking forward to use it on a real iPhone duo haha

[Li Junyi (LJ) @lj_ships]

Knuckle turns the iPhone Duo's hinge into a robot gripper.

Fold the Duo → a real SO-101 claw closes. Record a grasp, replay it hands-free, export it as 30Hz training data.

Yes, that's a real robot arm. No Poohs were harmed.

Built at @bitrig hacks with @JolinJiao

@paulg so do you think having some college experience (or even finishing college) before starting a startup is an good idea?

[Li Junyi (LJ) @lj_ships]

@cz_binance That’s the bro love

[Li Junyi (LJ) @lj_ships]

@Gaus450 Astra

[Li Junyi (LJ) @lj_ships]

@alexandr_wang Just tried muse, honestly the best personal agent I’ve used so far, especially love the integration. Only one thing, i want to use muse through my iMessage and i don’t want to switch back to main chat constantly. Otherwise, sci-fi experience and possibly the best meta product.
