But the Galaxy Tab doesn't have a paper-like screen ;)

True, but it can also do almost anything instead of just being a calendar and a picture ;) Any chance of having mini HDMI input to use it as something like an Onyx Boox Mira?

Probably not, I'd like to keep the device as simple as possible. The Onyx Boox already exists and it's great ;)

Hardware is hard:founding hardware engineer, we were acquired 4 years ago by a corporate. We place WiFi sensors around your network that behave like typical clients. We report on user experience and show when there are issues in your network. WiFi technician in a box. The fact that it’s subscription based is what made us float. The initial capital outlay, supply chain, compliance and design work is so funding intensi…

Does it actually connect or just measure the signal? If the former, have you had to deal with all the various auth schemes that companies use? I know that Cisco in particular loves to create their own schemes.

We're building Hoopfit, the most advanced basketball shooting machine ever.

It's battery powered and ultra portable so it can be used in your driveway hoop or you can take it to the park. It's powered by iPad Air so we heavily leverage the cameras for computer vision and AI to automatically track a players shooting stats and provide real time feedback on shooting form.

I'm a software engineer but I have to admit, designing and building a physical product is so rewarding and a ton of fun :)

It's the product I wish I had as a kid and desperately need as a recreational hooper trying to continue playing basketball as I get older!

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…

What counts as an unnecessary car ride for you? If I'm going to the grocery store and there's someone else to watch my toddler, I don't need to take her with me, but I think the bit of stimulation of getting out of the house and seeing a new place, new experience, and new people has a benefit that outweighs the almost inconsequential odds of a major car accident as I drive there and back on roads with a speed limit of 35 MPH.

I'm working on the world's brightest lamp: https://presale.getbrighter.co/ There has been a lot of writing about the benefits of bright light in your house and how to set up your own rig (e.g. https://www.benkuhn.net/lux/ ), but nobody has built a mass market consumer product (one that's easy to set up, has all the right features (dimmable, adjustable color temp, high CRI), and looks aesthetic). Feel free to contact…

Can you talk about the power consumption?

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…

I wonder if there would be a market for in-built hard modular mount points for the back seats. Like, let's say I'm Tesla. I build in mount points for the back seats. And then I sell accessories for the mounts. Tesla branded baby seats. Child seats. Storage/shelf solutions. Dog cages. Pizza delivery rack. Who even knows how many things one could put back there

It is called Isofix and most modern cars are have those (mandatory in US and EU):

We make a camera system for construction sites. Using computer vision, we can identify when and for how long subcontractors show up as well as notify our customers of unwanted behavior on site. https://bedrockwireless.com/ Fun fact, we probably have the best port-o-potty detector in the world.

How does knowing someone is on site lead to an increase in anything production wise? All they'd have to do is wander around and look busy. Some people are willing to do this over real work despite it being a task in itself.

Subcontractors are businesses, if they're paying people to wander around on site, they have big problems.

It's more about the fact that GCs struggle to get accurate schedules around when their subs will show up, the subs are in too high of a demand (think plumbers, electricians, framers). So they ask the subs to come out and complete a job and the sub responds with, "we'll be there sometime next week." Sometimes they show up, sometimes they don't. GCs need to know when and if they are showing up.

We're working on riderless and balance-assisted bicycles and motorcycles. We're working to ship our flagship bike and we're about to launch a balance-bike for kids that helps them learn faster and sets up virtual bumpers while they learn. Cool video of moto carrying stuff (just like the 2016 google prank vid) https://www.youtube.com/shorts/sqyjag9yRUA

You should track down the one-man team from the first DARPA Grand Challenge who made an autonomous motorcycle. I was on a team with a real truck, so I didn't have to figure out how to balance a two-wheeled vehicle while also trying to figure out how to autonomously make it through an obstacle course. From an insiders view, we all thought he was the star of the show.

I come from a traditional full-stack engineering background (web frontend + backend) and recently founded a smart toy company[1], the first product built on ESP32-S3. I took a few weeks for me to get comfortable writing firmware (although there is another more experienced engineer doing the primary work and electrical). I'm really excited for Espressif (the chip maker) to roll out newer versions of their microcontrol…

I have a similar background as you. How are you finding handling the mechanical side of things? I assume your toy is more than a PCB.

There are no motors, so more simple. There are mics, speakers, LEDs, LCDs, buttons, etc. I have a firmware engineer who also does electrical engineering, and a mechanical engineer who works with manufacturing, compliance, and industrial design.
