Hi everyone,
First of all, Happy Chinese New Year to everyone celebrating. Wishing you and your family a peaceful year ahead.
We’ve just come back from the holiday, and the team is back at work. The factory will resume this Friday, although most suppliers will need another 3–5 days before everything is fully running again.
To be honest, we didn’t really stop during the holiday. A few of our engineers kept working from their hometowns. It wasn’t a proper lab setup — just desks and living rooms at home — but sometimes that quieter time actually helps us think more clearly. We kept testing and debugging little by little.
The 10 units from our last pilot run have now all been fully calibrated and debugged. That gave us real reassurance. At least it proves the overall platform itself is stable.
The most important thing we worked on during the break was the IMU consistency issue. As we mentioned before, the new IMU initially showed weaker consistency compared to the TDK solution. That period was honestly quite stressful for us. During the holiday, our engineers kept refining the calibration and compensation algorithms, adjusting and testing again and again.
Right now, the results look solid. The new IMU can now reach performance very close to the TDK IMU. What surprised us even more was that under temperature variation testing, the new IMU actually showed better stability than we expected. We didn’t anticipate that. When we saw those results, it was a real moment of relief for the team, and it gave us much stronger confidence.
This is a video of our engineers debugging at home, and you can see that the IMU is now working perfectly：
Over the next few days, while we wait for the factories to fully reopen, we’ll continue addressing the issues identified during the last pilot run and finalize updated SOPs and quality documents. At the same time, suppliers for batteries, magnets, and metal parts have started preparing components according to our quality standards.
For the key parts that were modified — especially the plastic parts and the PCBA — we’ve requested another batch of samples for confirmation. You may remember the previous plastic issues: the button color didn’t meet our standard, and the screw posts needed to be extended by 0.2 mm. The injection factory will resume on February 27 and provide updated samples. If everything looks good, we’ll move to mass production shortly after.
We’ve already taken the first real step toward mass production by placing orders for components. Batteries, magnets, and packaging materials are gradually arriving at our warehouse. As soon as all the critical parts are ready, we’ll begin assembly immediately. I truly hoped we could start assembling and shipping by the end of February, but based on the current pace, March is more realistic. We have to be honest about that, and we’re genuinely sorry for the delay.
The important thing is that the IMU consistency issue — which was our biggest concern — now appears to be largely resolved. That matters a lot to us. Once we complete the additional lab testing in the next few days, we’ll share more concrete data. Our next update will likely come after we receive the improved plastic parts and PCBA samples, so it shouldn’t be long.
Thank you for your patience. We really don’t take it for granted.
If you have any questions at all, please don’t hesitate to reach out to us — this really matters to us.
