Add DePHY vending machine example

[jasl]

This is DePHY vending machine example.

We have a mocked online demo https://balance-payment.pages.dev/program

DeCharge decentralized charging network started from here.
Here is the show https://x.com/DeCharge__/status/1894414572414751215

And it also supports a Ghacha machine in our Denver DePIN event https://x.com/dephynetwork/status/1895176260919419141 (sorry I don't have a video)

@jasl is attempting to deploy a commit to the Solana Foundation Team on Vercel.

A member of the Team first needs to authorize it.

Cool stuff! Would you have time to add a bit more explanation to the readme about how the example works and how people can build and use it? And maybe a short video making people excited to try it out themselfs?

Sure! I'm collecting photos and videos and will add to the readme so people will know what they can build.
As you know, DePIN software requires people to have the same sensor, board, or device.
So, in the demo, we mock the actual interaction with them, so that people can reproduce it on their computer.

Maybe a BOM of how people could build a vending mashine with a raspberry for example would be really cool.

Haha, Gacha machine is this one

The demo is about you pay on Solana, the gacha machine give you a ball which contains a random prize

The whole demo can be reproduced on any ARMv8 SBCs or x86 computers.
Maybe we can replace the gacha machine with a more common device?

Yes maybe a raspberry pico and a servo. Then ppl can 3d print their own vending machines.
