WE'RE ORDERING ANOTHER 100 DEVICES People are buying our devices like CRAZY. These are all sample orders and we can't imagine what the volume's going to be like once our customers start scaling up. Luckily we're partnering with factories that pump out 1000 devices/day - if you need egocentric data collection devices, BUY THE SAMPLES NOW
Get interviewed by YC twice, get rejected. Doesn't matter, cause the hardware's working anyways. Re-launching AnchorCam Stereo, the next standard for egocentric. Stop wasting money on crappy data collection hardware. The no-brainer choice: - weight <80g - imu-to-trigger sync ≤14us (microseconds!!) - global shutter 1080p - commercially exportable chipset (not Hisilicon) - stereo mic / Wi-Fi 6 / BLE 5.0 / fleet management (Nov update) All of this for $240. Shipped within 3 weeks or GET REFUNDED Last time we were accepting pre-orders. They are finally in production now - and this time, we're partnering with JLCPCB's head of PCBA directly and sending the units straight to your doorstep. Find out more about the product on our website, link in thread. Never expected hardware to be this hard, but we've made it. It's good to be back. May all the data labs be with us!

We tested AnchorCam Stereo on ORB-SLAM3 in stereo-inertial mode with loop closure on. Walked 92m -> 2.1 cm in positional accuracy And this was the first proto board after major revision, it's crazy

Less than 80g. Stop hooking up ZED cameras to Raspberry Pis. Camera records to MicroSD directly.

Already making use of this
"Genjutsu" is Seedance 2.5 Edit. We removed the markup and made it 2.6x cheaper (and even better). Higgsfield Genjutsu : $0.318/s Sume Remix : $0.123/s Try now at sume.com/remix

Zap! + the agents scripting to fix impedance matching issues / power issues works better* Got our product AnchorCam Stereo to work on the first try * there was a human behind it prompting it (which is me). But yeah, it's getting easier to prototype good hardware fs
If you use KiCad with AI, you should expect a couple revisions- even if board is something relatively simple (ESP32 modules etc.). That is literally what we're seeing here from a major lab First revision success rate is higher w/ tscircuit, literally just tell your AI to use tscircuit and your boards will be designed faster and with higher first revision success rates

Real customers, real devices
Congrats on the launch 📈 just got 20

btw, all my respect and love to yc and those who got in :) @hiddnest taught me sales, @GaddipatiHarsha and his team invited me to their office when I didn't know anything about SF. Being obessed with customers is what can be learned, and applying to yc teaches you that

The engine that powers our designs
Introducing Zap! Zap! is an lightning-fast autorouter built to take down AI PCB dev cycle from days to minutes. After parting ways with my co-founder @MrPorkchop720 the company was met with a crisis of having to deliver AnchorCam Stereo (our main product) with no hardware engineers. I searched all over SF, Shenzhen, and Seoul but could not find engineering firms that could deliver production quality egocentric cameras that meets our exact specifications. I was afraid to tell to the customers about this situation - all I could do in the meanwhile was assemble off-the-shelf boards from partnering companies. But now with Zap! I can iterate on the boards myself without hand-routing - after Zap! is done the AI agents are usually able to fix the remaining issues through finishing touches. I actively use it to get AnchorCam Stereo production ready, and hope it enables many more to aim for larger problems that can only be solved through new hardware. You can compare Zap!'s performance with other popular routers in the link - it does really well. I am also working on an automated placer, so stay tuned for the next launch. I'll let you know when AnchorCam Stereo becomes available. To those who ordered and are still waiting, I greatly appreciate your patience and will get back to you as soon as we get our first fully working samples. Although Alex left the company, we remain good friends - he will be launching something exciting soon too, so shoutout to him @MrPorkchop720 - Yejun

How the Zap! logo came to be "How about a logo like this? Feel free to make color variations, but I want keep that lightning-feel to it"

Launching Zap! 1.1: A whopping 3.7x reduction in unconnected counts over 50 previously unseen boards + MCP & large board (2000+ pads) support I'm sorry guys, but Zap is so much better that we need a new benchmark for this. Human level routing is within reach

v1.1 reduces overheating copper sections by 3.2x over unseen boards. Zap! makes use of copper pours effectively, leaving less hot traces behind
