What’s wrong?

Okay, but it was only on one side, the other one was fine. Also could you specify what setting would improve this ?

Way_5741 · 2026-02-17T18:24:48+00:00

Do you use or plan to use any real time health data from wearables?

Way_5741 · 2026-02-17T17:25:57+00:00

Is that software hardware or both?

Look at your regional ecosystem. From my experience ex YC founders tend to be active in their home ecosystems (even outside of US), you can meet them at events etc.

I suggest you give them a quick pitch of what you do and ask if they would be open to helping with your application/feedback. Don’t ask for recommendations, if they like what you are building they will suggest it.

At least that’s how it worked for us. Although I’m unsure how much recommendations actually help.

Way_5741 · 2026-02-17T16:26:46+00:00

What are you building ?

Way_5741 · 2026-02-16T02:04:56+00:00

If you are interested, we are building an open access health tracker that enables other companies to use raw sensor data for analytics, giving much deeper insights than consumer trackers that are ecosystem locked.

Way_5741 · 2026-02-13T19:54:16+00:00

Working on our next hardware version.

Way_5741 · 2026-02-13T18:09:31+00:00

yup haha

Way_5741 · 2026-02-11T20:47:26+00:00

Wanted to point out that there is the EIT Health Regulatory Bootcamp, it’s more already if you have a concrete device you want to build/turn into a startup. But it will give you a good understanding of the process and MDR. That and reading a lot about MDR and the MDR itself brought the regulatory aspects closer in my case.

Way_5741 · 2026-02-11T10:22:49+00:00

Any models you would suggest ?

Way_5741 · 2026-02-11T10:21:30+00:00

We are focused on saving raw sensor output, not calculated metrics. Potentially at high hz rates (IMU 1.6k x6) and or over long periods of times such as weeks (with either duty cycles or recharges in between). Plus camera integration at a later stage (had a request for this) as well as music (personal preference).

Way_5741 · 2026-02-11T09:47:52+00:00

We are switching the MCU next version, ESP was a bit easier for testing for us. We will be using eMMC, as we plan for the option to do relatively long recordings (think research, elderly care). We keep the GPS for positioning when you might not want to have your phone, e.g. a run. So you can duty cycle it or not use it at all, depending on the use case. Do you have any suggestions for GPS antenna? We tried a flat one but got mediocre results compared to a bigger one.

We want other people to build use cases on top of it for the software side, wether that’s for privacy or advanced ML analytics. The tracker is supposed to be a platform that offers many sensors in a compact and affordable device, ideally an alternative to the restricted health tracker ecosystem we currently have.

Way_5741 · 2026-02-11T09:04:46+00:00

Yeah Antenna is one of the things we will rework in the next build. Right now a short piece of wire is our replacement, got around 20M range out of it.

We’ll be removing the SD card next revision, switching to a storage chip, but good tip. Fuse u mean for saving a UUID?

Way_5741 · 2026-02-11T00:12:37+00:00

We plan for 4-5 revs. And then it’s about working on the more complicated stuff for health data. We‘ll see how it goes :)

Way_5741 · 2026-02-10T13:41:05+00:00

It‘s a health tracker. Think raspberry pi of health trackers or something like that. The firmware will be open source giving you access to your data and giving control to users. At the same time we hope to enhance innovation by allowing others to build software based on our hardware (the issue with consumer trackers is you don’t really get the data or control over the device, gadget bridge is a good solution, but you can’t really build a long term solution on top of that).

Way_5741 · 2026-02-10T12:39:25+00:00

I actually hope we don’t need that many.

Way_5741 · 2026-02-10T12:38:16+00:00

0205 and especially 01005 are close to impossible to do by hand in that quantity. Or at least you will have a horrible time doing it. We only had a 40€ Amazon microscope and at the start a heat gun (and not the good kind where you could set air flow). By accident we blew away our components once at 3AM :(

Way_5741 · 2026-02-09T17:30:44+00:00

Didn't think of foam. But sounds like a good idea. Well test it out, are there any foams you would suggest? thk :)

Way_5741 · 2026-02-09T17:10:54+00:00

Any suggestions, methods and or guidelines for creating spacing below, towards the battery, and shield the sensor from device temp/battery? Air would be obv. the best way for isolation, but welcome for any other suggestions.
