I am a parent, and in my opinion, spending $1k on a car seat is completely unreasonable. (We bought ours used as part of a package deal with some other used baby stuff. It would have been nowhere near $1k when new.)

When buying used car seats, remember to check the "use before" date that is marked on it. They only claim to achieve the designed strength/protection for a number of years. At least in Europe.

What is that based on other than them wanting to sell more seats? I'd imagine the materials don't erode, otherwise how safe can it even be in the first place?

This is really cool. Can you talk about some interesting challenges/problems you encountered?

We started in 2016 with just an idea, and we probably encountered every problem you can think of ! - hard to raise funds for large deeptech projects (thank you YC and Wefunder for unlocking that one!) - a corrosion issue in 2019 that nearly killed us (we found a way around it after months of brainstorming and completely got rid of corrosion issues) - we had to build our own physics algorithm for very specific problem…

How did you get into conversation with DENSO? Channels through YCombinator or investors?

Can you tell me the difference between your product on the types of prescription cgm + insulin pump combos like dexcom/tandem which offer some level insulin control? I'm just curious. I run an xDrip set up and I've played around with a couple of the "DIY" closed loop setups.

Hey, my wife has diabetes, and she's had really awful luck with automated blood sugar monitors. Somehow their readings are always off by insane amounts vs a finger poke Have you done much research into that area? Do you know if there's a brand we should check out or any common gotchas? (I can't find much reasonable info on this online due to my poor Google skills and all the bad info out there..)

We had great luck with the latest generation of Medtronic pumps (the 700 range).

It used to be that they (older models) were off by huge margins, and the auto modes had to be constantly calibrated against as it was often not only off, but suggesting/dosing dangerous amount in either direction.

Nowadays, SO calibrates a few times a week and the pump is extremely reliable. Longer periods of highs are usually due to infusion set leaking (eg. line snagged and pulled the needle).

Like the other reply, it takes a day or two until the system is reliable.

Sensor on back of the arm, infusion on stomach is the combo we've found to be the most safe and reliable sites. Make sure you rotate as often as possible and avoid putting them in the exact same spot.

Quiet (* see below) * Safety > The US regs are pass/fail so lots of seats on the market have mediocre test scores that don't reflect the real danger of severe concussions. For those of you interested in digging into the obscure world of Head Injury Criterion: great…

Why only lap belt? Isofix is so easy.

Isofix is easy in theory but if you don't know exactly where the fixing points are, then it's like fumbling around in the dark. Sometimes it's hard to see the fixing points while trying to get the seat on.

I think that situation is something many parents recognize. Usually when the baby is screaming etc.. wonderful.

Once you've click the base in, it's easy next time though. Yet, my wife still considers fitting the seat as the man's responsibility. :-)

> You can configure this beautiful the e-paper display to poll any HTTP endpoint for an image. Just paste the URL into the iOS or Android app. The image will then be displayed on the screen. And when it changes, the screen updates. Looks pretty simple to do.

I think the idea would be to be support a way to set that HTTP URL via an API, not requiring use of an iOS/Android app? I imagine this might be a case of documentation and support as supposedly the app is already using the API endpoints we'd like to have.

Hmm, I'm not sure what you mean. How would you physically connect to this API without an app and without a backend?

I'm currently working on an Audio/Midi Recorder/Arranger for musicians/songwriters. Admittedly it's not a Startup, I rather aim to make it a SMB some day. And yes, hardware is hard. Especially for me as a Software Engineer by trade.

Track8 started when I wanted to learn Rust 3 years ago. It somehow evolved into a product.

Those chips should come in special packaging saying they're eco friendly

ball grid array perhaps has the right thermal properties

started reading here... it took me a while to figure out where the "chips" where coming from :-D
