The plushy controller I made is smaller and more compact then the layouts provided. It fits nicely in my hand and responds with minimal delay. All the buttons work perfectly
I made an additional line with conductive yarn from the GND port to the side of the controller. This allowed me to touch the yarn with my finger to ground the circuit in an elegant manner. This allowed the controller to be fast and responsive without making the grounding work to clash with the overall design aesthetic.
One finger must always be touching this line in order to ground the circuit.
