Your work is straight up addictive to anyone with an interest in physics, robotics, and coding. I'm legitimately thinking about reading up on PID controllers, because imagining the FIR/IIR (I think these are appropriate) diagram of literally rerouting the output of the gyros to the set point is just satisfying, regardless of the hackyness. I remember having a terrible time trying to develop a balancing robot with my childhood NXT, and this would have been just the encouragement for me to go more advanced.

I can see that most people are unable to spend 1000 bucks on a model, no matter how detailed and well made it is and that spreading that out to 100 payments will make it affordable. I for myself would never subscribe to such a thing. The waiting time would kill my motiviation and I would always fear that the company might go out of business before I have gotten all the parts.

The end product is never as good as advertised as they don't have to worry about quality - most people will never get to the last stage as they get tired waiting and realize how much money they were drained of, and those who do last already spent their money so there's no point for them to regret their investment as it won't change anything.

They're trying to get people hooked on the subscription because the longer you have been subscribed the more you "lose" on not completing the thing all the way. The only real expensive they have is tooling cost (all the injection molds, pretty pricy) and the licensing fees. They are offloading one of the most expensive steps in something like this, the assembly, to the customer. I'd bet the first 50 stages you receive are pure injection molded landfill junk. Actually, thinking about it, the entire thing is landfill junk. Pretty disappointed that James is promoting deceptive stuff like this, the website is deliberately vague on the amount of stages and total cost, and people do fall for stuff like this.

Whether or not you could fit that into a cane, idk :P

I was hoping you would make it a one wheeled robot and then you mentioned it. Would be cool to have both gyro and motorised wheel to balance in the different axes. But With one single wheel wit will probably spin around the vertical axis as well with only a single point of contact. So maybe a reaction wheel for a 3rd type of rotational control so you have 3 different rotational cotrol mechanisms for the 3 axes of rotation?

Could you build a Segway that is stabilized by a gyroscope? I had this idea several years ago and don't have enough knowledge of physics to have a clue about size, weight or speed of the gyroscopic wheel/s that would be needed. I imagine that you can stand on the thing and that it is somehow obvious that the stabilization doesn't come from electronics. If this worked with a lawnmover engine or something like that (steampunk like) or (even cooler) if you sat on it and would produce the energy by pedalling.

If you turn the flywheels 90 degrees so that one is in the front and one is in the back and gave the enough room to be able to spin all the way around 360. You could use them as reaction wheels and then once the are saturated rotate the flywheels purendicular to the spinning axis and get even more force once they have been turned you could slow them down like a reaction wheel and reverse them and the cycle continues. Theoretically it will always be able to balance and never saturate. If you try this please mention me.
