The cookies we create are temporary. Besides the basic ones that let us store your site preferences, some let us analyze site behaviour and some let us determine the impact of our advertising. That is, which types of ads are working and which types are not.
These cookies are essential for proper site function. They include things like the language you prefer, the country your IP address is from (so you can view the correct version of the page), and whatever cookie preferences you choose here.
These cookies help us understand behavior on our website and are critical to help us see which of our advertising and marketing efforts are working.
We advertise on a variety of platforms including social media and internet search providers. These sorts of cookies and the information we share lets platforms match you with your social media or internet search account (we can't see that information, only the platform can). That's helpful because it allows the platform to indicate whether our ads resulted in purchases or not. Then we can optimize the way we serve ads so that we aren't wasting money on ineffective ads. The platform also isn't driving you crazy with completely irrelevant ads. This doesn't make you get any more ads, it just makes the ads more relevant to you.
**Important: Choose the resistance value you want**
Overview
Spintronic resistors resist the flow of current. The higher the resistance value, the harder they are to turn. Resistors help keep circuits under control by limiting the flow of current.
Resistors come with fixed values that cannot be changed. You must choose the value of the resistor before you can add it to your cart.
Detailed description
Resistance is generated from shearing of silicone oil inside a sealed chamber. This gives a very stable resistance with low stiction. To make resistors of different values, the factory mixes silicone oils of varying viscosity.
Resistances are accurate to +/- 10% at the reference spin voltage. Note that there is a significant dependence of resistance on the spin voltage applied across the resistor due to the slight non-Newtonian behavior of silicone oil. See the datasheet supplied with the part for more information.
We LOVE this! My 13 yr. old has spent hours already since opening…

Quick help and very nice support
Our battery broke down after a while. The support was very friendly und helpful. They sent us a replacement within a couple of days (really very quickly!).
That was a very good customer experience and we already have the next products on the kids whish lists!

THANK YOU Upper Story
I bought my first Spintronics for my daughter. Then, I thought about giving it as a prize for our Erasmus+ robotics competition. Upper Story showed us what caring about pupils means and gifted our prizes ! This is a TRUE story about learning and care !

Beautiful story
I ordered Act One for my 6 years old son, he is really happy with it. Everything is perfect, but the shipping in my case to Poland was too expensive (100zł)

He hasn’t stopped playing with it since he got it. His favorite birthday present!
Das nenne ich Service! Ein defekter Artikel wurde kostenlos und in kürzester Zeit ersetzt! Herzlichen Dank für den tollen Support!

CODIGO ACTIVO
Perfecto para entender los conceptos de electrónica de forma mecánica.
Ya es la tercera vez que compramos este producto como regalo para un concurso de informática para niños que hacemos en León. Nos parece un regalo genial porque explica de forma sencilla y eficiente los principios básicos de la electrónica y la corriente continua, seguro seguiremos contando con este producto en futuras ocasiones. Además, la gestión del envío, facturas y problemas es genial, solucionan cualquier problema de inmediato. Muchas gracias.

Buen inicio
Llevamos solo 16 desafíos, que todavía son los más sencillos. Mi hijo tiene 7 recién cumplidos y acostumbrado a los Legos quería ir enseguida a las instrucciones para armar, pero valió mucho la pena iniciar con toda la historia aunque le costara trabajo leer todo. Hasta el momento puedo decir que es un juguete increíble, diseñado con muchísimo esmero. Algo importante es que con los niños que son más pequeños requiere de que papá y mamá se involucren, al menos al inicio. Estamos seguros de que una vez que pase todos los desafíos nos pedirá el Segundo Acto.
