I have planned to integrate haptics to the power station too, though traditional ERMs felt too cheap and unreliable, therefore I made something called the “Haptic block”, an LRA (Linear Resonance Actuator)-based haptic actuator, similar to the ones found in flagship smartphones (I’m looking at you, iPhone 6S!). Used a 12V, 6N solenoid along with a MOSFET, resistor and a flyback diode for switching the solenoid with the Arduino board.

It works great, started with the coding process, the timings have to be perfect, else, it feels like metal and plastic colliding (though that’s exactly what’s happening XD).

With perfect timing though, it enhances the user experience by a lot!
