It's great to see a teardown that also analyses the product engineering going on. Very nicely done.

The actual toy moving:<a href="https://www.youtube.com/watch?v=-1Y2WfcCb4M" rel="nofollow">https://www.youtube.com/watch?v=-1Y2WfcCb4M</a>My dog would love it.

We have one and I think myself and the kids played with it most of last weekend. I was hoping that the Bluetooth sequences might be able to be decoded so one could emulate commands (or create new ones) from a Bluetooth equipped broadcasting PC. If anyone has any info on anyone attempting this, please post.

Very interesting to see how it works in there. Though it is sad that it had to be cut apart though, it would be fun to upgrade it.

> Also note the lead weights used here to make the product feel more substantialAre these weights really made of Lead? Or is "lead weight" just an industry term for anything heavy? If they're actually Lead, how do toys like this conform to RoHS?

what are good resources to learn more about the product/material engineering they discuss in this article?

I start scrolling to read the article, and -- okay, what is this dev doing? I'm outta here!

Someone please make someone stop using large fonts on my phone that are hard and slow to read
