Hand-blown titanium crystal glassware for whisk(e)y and spirits. Produced in Europe by a glass factory that has been operating since the late 1700's. PG's mantra "do things that don't scale" has been a great inspiration. I wanted something comparable to high-end wine stemware and it shockingly did not exist, so I designed it during COVID. This is my first physical goods venture and my goodness, it comes with a lot of…

Neat! Ordered a pair. I especially love the dishwasher safety and lead-free elements

You can tell that guy's not a parent, haha. It's a shitload of money, but at least in this case I know that I'm getting value out of it. It's very easy to piss away a fortune on badly-made Chinese plastic trash in the world of baby accessories.

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.)

What do you think about spending $1k on a phone?

My question is why it's $1000 and not $999.

The price is insane man. The best of the best car seat according to lots of reviews(Cybex Anoris-T) is "only" £599, your thing is significantly more and I don't see why it's any better. Edit: sorry, let me rephrase that - not insane, just hard to justify.

I am always entertained by the extra amount people are willing to pay for the tiniest bit of risk reduction (or appearance thereof) for baby and kid related products. For example, paying an extra $900 for a car seat, but then taking the kid on unnecessary car rides, which are magnitudes riskier than not taking the kid in a car. If you are willing to pay that much for such an immaterial decrease in risk, surely you sh…

Why use dextrose instead of glucagon for lows? B/C patient liver function may be compromised more often in the in patient setting?

In addition to liver function, you can't always rely on patients to have glycogen stores to draw from. Additionally, dextrose is inexpensive, more available (rural county hospitals don't stock glucagon), easier to mix and store, has a longer shelf life, and most importantly, has a far quicker response time. Glucagon has promise for outpatient work, where the volume of fluid is much more of a factor, though the stabil…

Cool - check out my company: https://replica.health - We automatically log a bunch of data for diabetics based on things like activity and location, and provide an LLM powered search engine for that data. You can ask our system questions w/ natural language like "show me data about whenever I get low post-exercise". If theres any crossover, I'd love to chat about it.

#handWaveEmoji. Hello from Tapster Robotics, where we make small shoebox-sized robots for testing phones and other touchscreen devices (like payment terminals). Kind of an extension of my web and app testing work with Selenium and Appium.

We make the world's best baby car seats. https://www.kioma.us Fatherly Magazine calls it "The Car Seat of the Future". It's been crash tested, flight inversion tested, flammability tested and mom tested. It is full of patented innovations to make kids safer and parenting more enjoyable. It required lots of material science, production techniques, supply chain adjustments, and a surprising amount of software (to model…

The strap is a single point of failure. Each mount should be attached to the seat brackets individually. Those brackets need to be braced and not just bolted through plywood. Having patents on innovations is necessary, but if you have innovations that will save kids lives, you should find a way to make those broadly usable by all. https://patents.google.com/patent/US10967762B2/en?oq=1096776... This this TOS usual for…

if you have innovations that will save kids lives, you should find a way to make those broadly usable by all.

One way would be for you to buy or license the tech and give it away. Is that something you're considering?

Regarding safety, do you have any links around the test results for the Kioma, or other car seats? You've mentioned a lot about the safety scores/test results in comparison to other car seats, but I couldn't seem to find a single mention of that stuff on the website? I also tried to see if something like Consumer Reports had a review of a Kioma car seat (either the current one or the carbon fiber one) but they had no…

Test Results > NHSTA used to publish their test results of all car seats, but no longer do so. FMVSS 213 (the US standard) tests for Head Injury Criterion (36 millisecond), Excursion, and Peak Acceleration in a frontal car crash. So keep in mind the utility of the results has limits, and doesn't test for a whole lot of things that are part of real-world usage in and out of a car. *Big grain of salt.*

I'll give you some real numbers and leave the comparison for you to do (lawyers get itchy if we do the comparing directly). Our carbon fiber seat's best result is HIC 197 in FMVSS 213 testing with a Crabi 12-mo old test dummy. Our friend Eli at Magic Bean's reviewed it in a video at https://www.youtube.com/watch?v=fGaU9R6jHCQ The current car seat for sale is of a similar class but doesn't have the $2500+ price tag of a carbon fiber seat.

If you're still curious, we can take this off HN: drop me a line at support@kioma.us and just mention HN and your HN profile name.

We've built Matic - A privacy-preserving autonomous home robot

5.5 years ago, we started building an autonomous home robot with these goals:

* Reliable autonomy — no user interventions, it should just work * Everything on device — no cloud storage or compute, robot-to-app data through local WiFi * Usefulness — solve a genuine problem that will impact real people

To achieve this, we * wrote the robot's software stack in Rust * used only RGB cameras and Mics as input — humans can navigate with only these sensors, so why can’t a robot? * developed SLAM and computer vision algorithms that run on-device, in real time, with centimeter-level precision and semantic understanding * gave our robot a purpose — starting with floor cleaning allowing us to develop specialized hardware for vacuuming and mopping w/o chewing up wires or getting stuck.

We're a small team of Let us know what you'd be interested to learn! We'll also answer questions here and look forward to your feedback :)
