#2Fully compressed I believe the opposite poles fields begin to attract each other, counteracting the matching poles repelling one another, and explaining the alternating pull force.

#3TL;DR Yes but not very well. A spring made from magnets doesn't have a close to linear spring rate like a traditional coil spring does.

#4could some kind of conical shape offset the different power curve?

#5Loved the video. Didn't love the loud beep near the end, that's at about 3x the volume of the speaker the whole video...

#6Seems like electromagnets could help compensate for distance by drawing more current when far apart, and less when close together. A microcontroller could essentially make the force linear like a spring. Of course, then you need wires hooked up to your pogo, and that might be scary if the microcontroller has a bug (or somehow fails) since you are now essentially hopping onto a railgun.

This is the best comment I have ever read

#8They should try this with electromagnets, and make the curve linear using electronics (and perhaps find the optimum curve in terms of fun when jumping around).

Coil spring + magnets = success?

#10The core issue that's not mentioned is that we want a certain kind of a curve for deceleration because that what determines how the spring works. Little resistance first and lots at the end means it's not much different from just falling down!
