Spintronic-Diode Sparpaket

The diode is kind of the missing component of spintronics. Although it can be improvised with a transistor and a junction, the actual diode works a lot better. The ratchet mechanism makes a sound, so you could even consider this diode an led! Some of the act 2 puzzles that Involve diodes actually rely on the 1.5v drop from the transistor junction combination, but the others do work better with the real diode.
So far I have only needed 2. This is because spintronics chains go both ways at once so the spintronics diode is more like a pair of diodes. Therefore I haven't built anything for which I needed more than 2 diodes yet

It's arguably louder than the ammeter, but the thinness of it compared to the alternative diode (junction + transistor) is much smaller and leaves more room for more components, and hence more complex circuits.

My 8year old son, had a fantastic time playing with the spintronic Act 1, and I plan to purchase a full set for ourselves.

My son borrowed this set from a friend of ours, unfortunately within the first 20min of play, he accidentally broke the rose gold looking connector, and the spring on the spintronic diode fell off, and got lost. I was very worried for him to continue playing with their toy, in case he broke more parts.

It’s great that we can buy replacement parts, but is it possible to purchase these sub-items separately?

Fun
