A DIY Raspberry Pi vending machine has been created by Christopher Natan using a little Arduino programming and hardware. Full instructions on how the project is created have kindly been published to the Hackster.io website available via the link below.
Project Capabilities and Features
The Raspberry Pi vending machine is capable of sending Top-up to any prepaid mobile (Globe, Smart, Sun) networks and can also serve as a wireless hotspot. This dual functionality makes it a versatile and practical solution for various environments, such as schools, offices, and public spaces. The project uses a number of programming languages including Android Java, CakePHP Framework, PHP, MySQL, nGinx, Python3, NodeJs, and Shell Script. This diverse range of technologies ensures that the vending machine is robust, scalable, and efficient.
In addition to its primary functions, the vending machine can be customized to dispense various items, such as snacks, drinks, or even electronic accessories. This flexibility is achieved through the use of programmable hardware components and software scripts that can be tailored to specific needs. For instance, the machine can be programmed to recognize different coin denominations or even integrate with digital payment systems for a cashless experience.
Hardware and Software Components
The hardware used in the build includes:
- Raspberry Pi 3
- Coin Acceptor
- APEX 7000 Bill Acceptor
- Channel Relay
- OptoCoupler
- Android Modem Router that supports flashing to OpenWRT firmware
- 10 inch Android Tablet which has been rooted and only allows one application to be run
The Raspberry Pi 3 serves as the central processing unit, managing all the inputs and outputs from the various hardware components. The Coin Acceptor and APEX 7000 Bill Acceptor are responsible for handling cash transactions, while the Channel Relay and OptoCoupler manage the electrical signals that control the dispensing mechanism. The Android Modem Router provides the wireless hotspot functionality, and the rooted Android Tablet serves as the user interface, displaying options and processing user inputs.
The software stack is equally impressive, utilizing a combination of Android Java for the tablet interface, CakePHP Framework and PHP for the backend server, MySQL for the database, nGinx as the web server, Python3 for scripting, NodeJs for real-time communication, and Shell Script for various system-level tasks. This comprehensive software suite ensures that the vending machine operates smoothly and efficiently, providing a seamless user experience.
