Why not lay everything on a pcb and have the factory solder boards for you ? Jlcpcb can do this. I believe pcbway can do that too. Your product will also look a lot more neater. I would also suggest to add a video of your product in action. I believe it is about jumping on your chair to play the game but it is unclear to me.

A PCB in my case can only be used to replace the NodeMCU board but that might exasperate my woes without adding any value, Because any custom PCB solution isn't strong enough to replace the switch(button on 170 point bread-board) which goes under the butt cushion.

A new video is coming soon, There's a old video showing the setup if you scroll a bit. I thought leading directly to the game made more sense, Perhaps I should interchange manual trigger and 'connect to the butt trigger' so that people can try manually first?

Edit: The game now suggests manual trigger first instead of connection to the Butt Trigger.

I'm skeptical that a PCB is less strong than a breadboard. Have you tested this? If you use an SMT button you can always add a reinforcing layer of plastic under the PCB. If anything, surely it would be more comfortable to sit on a low profile button? Or some kind of strain sensor pad.

I've tested numerous methods over past two years; But the simplicity, reliability, structural integrity and cost of 170 point breadboard is hard to beat as its an inch thick(built like a lego).

I even tested with velostat fabric, but the resistance varies a lot and so there are numerous false triggers or missed triggers since we don't sit still on a chair.

No matter what's the thickness of the setup is, Any solid material under the butt is uncomfortable and so we need butt cushion for the setup. But with butt cushion, SMT button doesn't function as there's not enough travel, So we need a momentary button with button cap for enough surface area and travel to push into the cushion when we get up.

I think you could simply make a big switch on a pcb yourself: make your circuit on the pcb and have two exposed metal pads as the terminals of your switch. Then have another metal plate, put some springs in between for separation. When the person sits, the metal plate closes the circuit, which acts as a switch

Exactly what I’ve done before, if components are all on one side then this is the easiest route
