I am making and selling an eink smart screen. It can display a google calendar. You can also point it to any url that serves an image. Is it okay to post a link? https://shop.invisible-computers.com/products/invisible-cale... I am planning to release more applications for it and I am opening the platform for 3rd party applications.

Love this idea, been waiting for you to ship to Canada and now finally purchased :)

Currently your Android app isn't available in Canada yet though

I'm guessing since it's plugged in, there was no way to make it last long enough on a battery? Love the idea, will bookmark it for the future office!

Battery is harder to make safe and harder to certify as safe. Plus, I like the idea of plugging it in and never having to worry about it. Still, I am thinking about adding a battery about twice per week, so it's definitely on my mind.

Consider a "bring your own battery" option where you have an interface that's moderately standard.

Just ordered. Looking forward to getting it!

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...

Not sure what you are referring to about a strap being a single point of failure. Patents > We don't work for free, and we can't buy groceries by giving away years of R&D. Companies are welcome to license our safety innovations, and they know how to reach us. The invitation to do so is on our website. TOS > Kioma seats come with an industry standard 1 year warranty. The website TOS are different than the product warr…

“We don’t give years of R&D away for free” is a pretty flippant response. You make money selling car seats, and if another company can produce better seats at a lower price then consumers win and lives are saved. Which is ostensibly exactly what you want to happen? Otherwise why even be in the car seat business?

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…

Fascinating. It’s like a cross between a Teku glass and a white wine glass. Gorgeous.

Thanks! I like seeing how many folks know about the Teku beer glass. Very different use case, but the shape philosophy is similar.

With Bennuaine it was really about fine-tuning the dimensions through a ton of research and prototyping to reduce ethanol burn while at the same time highlighting finer notes.

We make an e-commerce subscription that uses a smart scale to trigger re-orders at the perfect time. The timing is dynamic for each customer’s usage patterns.

The scale lasts 1.5yrs per battery charge. Our customers cancel subscriptions at a way lower rate compared to typical subscriptions because their experience is way better.

We bootstrapped to over 100 customers. We 3D printed the devices and hand soldered dev boards for the internals.

We manufacture the device ourselves in China, now.

Company is bottomless.com, though we are now focused mostly on integrations with third party e-commerce sites over direct customer acquisition.

I see that shipping to Europe is not yet supported. Do you have plans soon?

CE certification is extremely expensive for a bootstrapped startup. Plus there is Elektroschrottverordnung and Verpackungsrichtlinie and all that stuff. You can send me an email at info@invisible-computers.com

Wait, you are situated in Flensburg but not shipping to EU? That seems rather interesting... Do you also manufacture in germany or have you sourced that out?

Why are you driving them inside a car that has literally all of these in the first place then?

GP's asking a legitimate question about chemical outgassing etc. Parents have concerns like this, and some parents more than others. let me go pedantic and teach: "The customer is always right" does not mean that no matter what a customer says, you give them a false smile, and pretend you agree with them. "The customer is always right" means "you are hearing actual feedback from your target audience; somebody giving…

The user you're replying to appears unconnected to Kioma, so I don't think they have any winning-over to do here.

Not mine, but was impressed with IceWhale technologies. They shipped a custom SBC (Zimaboard) during the covid electronics supply chain shitshow. Was delayed as a result but they came through with solid execution eventually.

We are building the world's highest temperature heat pump. It can reach 1000℉, when other commercial heat pumps usually reach a maximum of 320 ℉. It is a big deal because factories have to rely on polluting natural gas to produce their process heat. We estimate that it represents 3% of the world’s annual CO2 emissions and a $10B+ annual market opportunity. We are currently building a 5kW prototype at 480℉/250C to coo…

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 problems, and ended up selling the software we use internally to DENSO (a large japanese company) which funded the development. See https://tanatloc.com

- tackling a market that doesnt exist yet with a seasonal energy storage solution (a change of engine architecture allowed us to use the same engine but for industrial heat pumps, an existing market much easier to tackle)

- finding the right industrial space,

and so on :)
