Yes, I fully understand the time problem. I put off building the crib until my son was 4 months old expecting to be able to finish it in 2-3 weeks. It took over 8 weeks and by the time it was done it was at least 1-2 weeks overdue. And a lot of the work was done between 10pm - 2am when everybody was asleep, which took away from my sleep! I'm still glad I built it (now that it's done!), but yes, outsourcing it certain…

Got a picture of it?

Please, please, do not use something like this as the only method of monitoring a child’s safety. This sort of thing has given me honest to god nightmares. My day job is managing development and infrastructure of internet connected cameras, with motion detection, notifications, and all the rest of it. Every now and again someone new will start on the marketing team and put together something about using them as baby…

I've been an SRE before, and have kids. I don't think there's any real expectation that a baby monitor is a reliable alerting system that can be depended on. There are definitely people in the thread who believe that's the case, and it also looks like some products are built to those high standards, it's not legally required, and I don't think it's even desirable. I don't hold the people who care for my children to t…

Even if you get the perfect training data, the state-of-the art neural networks will not be 100% reliable. Convolutional neural networks work by recursively recognizing shapes. In theory, the first layer should match the picture on something like this and conclude "it's probably an eye": o o X o o o X X X o o X X X o o o X o o (above, "X" denotes low relative brightness, "o" denotes high relative brightness). The nex…

I don't know your woodworking experience, but I don't think building a crib is dangerous at all. The safety standards are pretty straightforward and they are very clearly spelled out. And for me at least, no mass manufactured piece of furniture is even close to a minimum quality that I'd build myself. On the other hand, a crib is a particularly annoying piece of furniture to build. First, it has to be able to break d…

Where my partner usually steps in is not safety, but time. It is great if you're able to build some things yourself. But the kid and in particular your partner need your hands on deck, not on the workbench for days on, just to end up with an unfinished crib. And there are so many other, more important things to do that cannot be outsourced that easily. And once the first kid is in the house, expect interruptions. Oh,…

This is great and all, but it has to be 100% utterly completely reliable with no false-negatives. If it doesn't tell you (i.e. false negative) even once , then you can guarantee that it will never be trusted ever again, especially by the birth parent. We've gone through a range of frankly awful monitors and cameras that simply were not reliable. E.g. cameras that would regularly go offline for maintenance between 3am…
