I need to get one of these. Err, for my kids, I mean.

The term "spintronics" already has a definition, and it has nothing to do with gears, but with electron spin angular momentum, a fraction of the reduced Planck constant ħ. Re-appropriating long-established scientific and engineering terms does not help children with science.

It is mechanics, not electronics.

It does look cool, but as a physiologist and child development specialist, it just keeps kids sitting on their asses a little bit more.

Why? It is a dead end educationally. The entire scientific and engineering world uses fluid flow as the analogy for electricity, & this conflation to chain drives seems like a really terrible idea. Fluid flow much better and more intuitively describes voltage and current.

The basics of Ohm’s Law. Ohm’s Law explains the relationship between voltage, current, and resistance in an electric circuit. Where: V = Voltage, measured in volts I = Current, measured in amperes R = Resistance, measured in ohms In simple terms: Voltage is the push that moves electricity. Current is the flow of electricity. Resistance is what opposes or slows down the flow. So, if voltage increases, current increases. If resistance increases, current decreases.

The toy meeting at the beginning of Toy Story introduced the characters in a fun and memorable way and set the table for what will become an iconic film franchise.

I recommend this toy Snap Circuits - It taught me more about electricity - Many of the projects are fun for both father and son - It gave my son a sense of electric circuits and taught him to persevere through instructions for the reward of seeing his electrical machines work

Filmmaker Öner S. Biberkökü shares his "screenshot strategy" for building a full narrative from a single starting point during this In the Flow interview. Thanks Oner for the partnership! "At the end of the shot, you can take a screenshot, give it again [to Flow], and you now have a new image of that character in a different situation... So I think, with one image, you can stay in the flow, and make a story." Watch his breakdown:

You can almost feel the stampede of thousands of horses bursting out of the screen any second now! This is the Huangguoshu #Waterfall —Asia's largest—at peak flow. It's only when you set foot in Guizhou that you truly grasp the magic of this land. #AsiaNo1 #Epic #Majestic

Here's a comparison of a rough draft vs the final edit. Back in October I posted the first version of this video, but after touching it up, now it feels like the scene came to life. You can feel emotion for the raid and the camera angles flow better with the song GW2 comes out in less than 30 days, more sneak peaks coming soon

Check out this cool encoder I found (on sale!) at LCSC Electronics. I love the idea of a mechanical part that just spits out binary, especially when the pins are nicely in order like this.
