Feel the pull of voltage and see the flow of current. Electronics is abstract, but Spintronics makes circuits tangible, irresistibly touchable, and deeply intuitive.
Learn to bend raw energy: split it, store it, multiply it, reverse it, and shape it to your will. It’s what electronics is all about, and with Spintronics, you can finally experience it.
Lose yourself building circuits without getting bogged down by math. Build a deep, intuitive understanding of circuitry through 145 fun and fascinating puzzles.
The spintronic battery powers your spintronic circuits.
The spintronic inductor builds momentum.
The spintronic capacitor stores energy like a spring.
The spintronic junction allows current to branch, like an electrical junction of three wires.
The spintronic ammeter lets you hear the current.
The spintronic transistor is a voltage-controlled resistor.
The spintronic switch opens and closes circuits.
The spintronic resistor resists the flow of current.
Novice or expert, you'll never see electronics the same way again.
Parallel Circuit
A junction branches one loop into two.
Series Circuit
Two resistors add together to slow current from the battery.
Buffer Gate
The output voltage is the same as the input voltage.
NOT Gate
The output voltage is the opposite of the input voltage.
Capacitor Backup
Capacitors provide stored power for a short time when the battery is turned off.
Voltage Divider
Two resistors in series divide the voltage to a lower value.
NAND Gate
The output voltage is high if one or both switches are off.
Voltage Amplifier
A transistor amplifies a small voltage into a larger voltage.
Darlington Pair
One transistor amplifies a small voltage into a larger voltage. Then a second transistor amplifies that into an even larger voltage.
Biased Transistor Amplifier
A small voltage (a "bias") is constantly applied to the transistor's gate, putting it in the middle of the active region. This makes it respond to both positive and negative input voltages.
Full Wave Rectifier
Both halves of an AC signal are turned positive (i.e., they both turn the ammeter clockwise).
Full Wave Rectifier (Smoothed)
The rectified DC output is smoothed by a low-pass filter.
Buck Converter
Efficiently converts a higher voltage to a lower voltage.
Boost Converter
Efficiently converts a lower voltage to a higher voltage.
Delayed Feedback Oscillator
Converts a DC source to an AC source.
Relaxation Oscillator Circuit
Two transistors flip each other on and off in turn.
Constant Current Source
This circuit automatically adjusts the voltage to keep the current through the load constant.
Flip-Flop
The basic unit of binary data storage. Press one button momentarily to turn it on, press the other button momentarily to turn it off.
Pulse Generator
Press the button and the ammeter turns a short while before automatically turning back off.
You become Natalia, a master clockmaker who stumbles across an alternative technology that could change everything. Your job is to help her build increasingly sophisticated spintronic circuits to meet ever-more-challenging needs.
Each puzzle begins with an objective. Players build the starting setup and then determine how to add the available parts to build a circuit that meets the objective.
