@vhmth @jashsparrows @aililiuu @Robo_Tuo are best for getting plugged in

Planning a trip to China to visit factories and hardware suppliers. Feels like discovering a new world in a video game with a completely different leaderboard. I don't recognize most of the top usernames, but there are some I do (Musk, Cook, etc). Excited to see what it's like without the filter of US propaganda.

@haydendevs blinky is def hello world

what is the EE equivalent of a react todo list

I would say microphones and speaker being capable of taking phone calls and listening to music is a pretty big feature miss, Spectacles 1 didn’t have a speaker, 2 and 3 don’t let you use it for phone calls or music. Then the AR generations are hella bulky. It misses in design and functionality. They over indexed on 3D photo and video sharing.

@localghost Boring, linear improvements in battery life, camera quality, and the syncing UX The v1 Meta glasses (2021) also flopped, they only finally succeeded in v2 (2023) when it passed the right thresholds for comfort, resolution, and battery life.

Who has the best explanation for why Snapchat Spectacles didn’t work that accounts for Meta Raybans taking off now?

@coffeewithjer Missing breakfast burritos so much in Shenzhen 🌯

Not one person has ever said it’s a bad idea to move to San Francisco for the burritos

@AndersDoesTech Send me TestFlight!

humane ai pin companion app for ios, incoming. you’ll be able to: • sync contacts to your pin • quick overview of battery and storage status • transfer captures to your iphone • install esim with a simple qr scan • configure wi-fi • configure openclaw

@gracecbear @irvinxyz @Robo_Tuo Lots of English speaking expats, events, and founders here! Honestly comparable to SF but you build a significant hardware community more quickly here

@irvinxyz @Robo_Tuo Are these fully English-speaking sessions in Shezhen? :) Cool! When are you inviting me to go?!

Day 1 in Shenzhen: meet @Robo_Tuo Day 2 in Shenzhen: visit manufacturers Day 3 in Shenzhen: build humanoid robot That’s just how it works here.

@FarzaTV @shaiunterslak @makesomething0 Sick!!!

Introducing @makesomething0 A place to learn AI alongside others. Pick up new skills by joining live sessions led by rlly great instructors + learn by building with the existing tools and shipping your ideas. Education is missing from the space. We wanna help. P.S: It's free.

Nanshan (Cloud City area) or Futian (HQB area) is great because you’re very close to everything and it’s very modern. Cloud City has Seeed’s Makerspace and a lot of nice offices. HQB has Troublemakers and a lot of component and shops for prototyping. Bao’An and Dongguan are where most production CMs will be but are quick DiDis to get to from either area.

@sabakarimm we get into the 2 ways of developing wearables at 5:49 but Andy flagged he's not sure on the best place in shenzhen for an office. @caydengineer (hello!) may know?

On building consumer wearables in 2026 In conversation with Andy Kong @oldestasian interested in hardware? me too. fascinating chat, amazing lab aesthetic 00:00 quiz-bowl buzzers to the SF wearables scene 02:25 pebble, kickstarter, and what's changed 05:49 2 ways of developing wearables 06:59 CMs, budgets, and designing your own board 09:53 using Alibaba chat to source partners 14:07 planning a shenzhen trip 18:27 board vs mold design 25:53 boston vs sf vs nyc for wearables 30:00 LLMs + board design 33:50 is hardware still hard? 36:22 cubesats + chargerless 37:11 validate publicly, quickly

@AviSchiffmann @oldestasian @ashebytes It’s not just a function of time and cost, it’s a function of quality as well. You can still retain all IP and most CMs will happily sign NNNs and are trustworthy. The sheer amount of talent and resources in Shenzhen and just how advanced it is as a city is insane.

I find the slower process by doing it in the Americas is actually nicer because gives you more time to think. I do agree it’s not nessasarily cheaper but it’s also not outrageous and I’d like to see more local PCB shops become a thing. I have certainly optimized for the artisanal angle tho

@plmsda This goes hard

LV x TSMC

@sabakarimm @sandbar @chargerlessxyz @tayanecklace @fortwearable I really like this little guy @dankuntz

Loving all these consumer hardware/wearable launches: 💍 @sandbar private voice ring ☀️ @chargerlessxyz health tracker 🧠 @tayanecklace intelligent jewelry 💪 @fortwearable built for strength training What else is coming?

@RealDimgba @MKBHD It’s really RAM that’s the deal breaker, even like 32GB MacBook Pro runs into a lot of issues with agent orchestration or a lot of containers.

@MKBHD Coders should be a C-. Yea, will work for basic web development, but once you start needing docker and working with large codebases, it will age really fast. Plus, good luck emulating mobile apps for development.

At the risk of spoiling my entire review, I present to you: Rating the $599 Macbook Neo based on who the customer is: youtu.be/iGeXGdYE7UE

@sabakarimm @toddsaunders World class

@toddsaunders sweeter.design makes great landing pages

I’m constantly asked for intros to website and logo designers. Who are the best ones you’ve worked with? Tag them below or feel free to DM me.

@faizan10114 @rishabkrjha Also the @mwseibel and @daltonc content is golden. Kevin Hale and early Sam content is pretty good too.

You have to realize that YC videos are targeted towards people trying to build VC backed startups, unicorns. The business advice is not relevant, at-least not in the recent videos. Treat it like a datapoint, but not a gospel. I would ignore all recent YC videos TBH, just read @paulg essays, they are more relevant now than ever, and start building. paulgraham.com/articles.html

I’m honestly pretty confused right now. One moment I see the Cal AI founder hitting $50M ARR at 19 and think maybe I should build consumer phone apps. Then I see all the hype around OpenClaw and feel the FOMO. Then I think I'm a developer, maybe I should build a devtool. Then YC says “build for agents, your new customers are agents.” Then others say “automate one full workflow with AI” and build a business like the ones on Starter Story. Finally built a Payment Gateway for AI Agents, Stripe launches the exact same thing next week. Back to square one 🥲. There's just so much noise. What I do know: I don’t want to go the VC route. I want to be profitable from day one, build something meaningful, and reach $100M in the next 3–4 years while genuinely improving people’s lives.

@livinoffwater @Robo_Tuo @aililiuu @jashsparrows

Flying to Shenzhen tonight. Documenting my journey through Huaqiangbei and the streets of Nanshan Who should I meet out there?

@livinoffwater @djytwy Time Square for electronics

@djytwy No. What is that?

questions NOT to ask a hardware founder: – how long is the battery life? – are you SOC 2 compliant? – have you been to Shenzhen?

@MrBased00 @mzu_maclean @ianzelbo @ycombinator @Heypocket @AkshayNarisetti @gabrieldymowski This is giving 😂😂😂

@mzu_maclean @ianzelbo @ycombinator @Heypocket @AkshayNarisetti @gabrieldymowski on Android you can literally bypass this thing, also you can use another phone to record the usecase is too narrow this shit is useless only consumerism chuds would buy this

Pocket (@heypocket) is your notetaker for real world meetings. In the last 5 months, the team has delivered over 30k units with a $27M annualized run rate, growing 50% month over month. Congrats on the launch, @AkshayNarisetti and @gabrieldymowski! ycombinator.com/launches/PaX-p…

@Laz4rz @hrolnd Plaud is at a $240M annual run rate it will hit $1B+ in sales within 3 years. There is huge market demand for products like this so a premium entrant makes sense

@hrolnd HAHHAHAHAHA NO WAY

There is just no way this got accepted at YC They go from “app could do the same but this is just so effortless” to “you can stick this to your phone and then all your summaries are on the phone app” in like 15 seconds WHAT?!

@ivanburazin @AnushDSouzaa @zephyrlogs I agree, no one wants to wear glasses all day

@AnushDSouzaa @zephyrlogs I'll bet you they aren't, at least in the next five years

I could just use Granola on my phone x.com/ycombinator/st…

@ivanburazin @sabakarimm Someone should start a polymarket for this 👀, 200 million units sold across ambient computing devices by 2030.

@sabakarimm I'm happy to take the other side of the wager. My strong belief is that no physical device will go mainstream in the next five years outside your phone.
