The Brazilian businessman Ricardo Reis, wishing to demonstrate one more example of the potential use of the first cryptocurrency, created his own bitcoin-espresso machine. This is reported by CCN.
According to the businessman, he doesn't work directly with cryptocurrencies, but he has been investing in bitcoin since 2016. He also says that the bitcoin-coffee machine was created to study the potential of the market, and to show that the first cryptocurrency has various potential uses, including as real "programmable money."
I developed a device that powers the coffee machine with Bitcoin transactions to study and have fun. Dealing with technology, for me, besides work, is a hobby. My intention was not to create something to explore commercially, I wanted to simply explore the technology’s capability and show other people how BTC is ‘programmable money.

The machine starts when the bitcoins arrive at the purse connected to it. The device has a QR code that allows users to send money and pay for coffee.
As creator says, he used the Raspberry Pi processor and encoded the machine with PHP. At the moment, the coffee machine does not use the Lightning Network protocol, but in the future Reis plans to use this technology to create another device.
