Time for the next installment in our "Made in the USA" series, telling the story of making here at Rest Devices.

As we've shown before, we use our CNC Mill and 3D printers to rapidly test new designs and functionality. We also love to stay as close as we can to every aspect of our product development, so we build everything ourselves.

Today, we're prototyping new ways to heat and cool a bottle for the next Mimo product coming off the line: the Smart Bottle Warmer. The part being 3D printed here is a prototype of what a bottle would sit on inside our bottle warmer. Testing individual parts like this often gives us new insights into how complex components will interact with each other.

And no, I didn't plan on dressing to match the parts.

If you read this blog and you've followed our story, then you know that here at Rest, we do all of our own research and product development. We love being close to the product, manufacturing, and all steps of fulfillment. Fundamentally, we believe that this ensures our customers are getting the very best.

Here, the next installment in our "Made in the USA" series on the Maker culture at Rest:

Part of the R&D process involves making Turtles and Lilypads, so we thought we'd give a glimpse into the Turtle-building process. Here, Tigran is building Turtle bases, and programming their boards to ensure super easy connectivity for parents when they open their Mimo and are going through setup. Thomas, our CTO and co-founder, is also frequently involved in each step, as he develops innovations (e.g., a robot for aligning Turtle bases) that make manufacturing more efficient and production ultimately more successful.

First: we use a super technologically advanced method to give our Turtles their magnetic feet: stamping. The Turtle base is placed in the mold, magnets attach to the stamp foot, and voila!

Once the Turtle bases are given feet, they're placed in long lines called "snakes

As you know, we do all of our own R&D. Something we're proud of, but also something that's become a big part of who we are as a company, what we stand for, and how we envision the future of our products and our industry.

To highlight all of this, we'll be starting an R&D blogpost series called "Made in the USA," starting with a very core component to early design and prototyping: our 3D printer!

So what are we 3D printing today? I asked Silas, resident Hardware Ninja, and Katy, Lady of the Machine:

"Today, we're printing parts for a jig that we'll use to make the Lilypad building process much more efficient. The jig will ultimately be used to easily align Lilypad pieces together in the gluing process. And, it's a great excuse to use translucent purple in our development process."

Stay tuned for more adventures in 3D printing!

We have put a huge amount of time and effort into ensuring that the respiration graph displayed in the app and the alerts sent out about respiration are accurate. Even more than this, we believe that you have a right to know how we generate these graphs and alerts so that you really understand what they mean. This blog post will walk you through our process.

When we look at the respiration data right off the sensor over a night of sleep it looks something like this:

The first thing we do is figure out if the Turtle is on a baby. Obviously, it would be totally unhelpful to send you a graph or alert if the Turtle is sitting on the changing table while your baby is happily gurgling in front of you. We do this by looking at all the data we can: the respiration data, both at a given moment and for the past couple of minutes; the temperature data; and the activity data. By combining all these factors we have a pretty good idea of what is actual respiration data and what is just noise.

The next thing we do is normalize the respiration to the
