Create a powerful home PC with 3D printer and Raspberry Pi

If you only need a basic computer for typing, sending emails, and browsing the internet, buying a second-hand PC might seem like the obvious choice. However, there's an even smarter and more cost-effective way: building your own with a Raspberry Pi and a 3D printer. According to Tiangong News Agency, this DIY approach not only saves money but also offers a fun and educational experience. Recently, Adafruit, a popular open-source hardware site, published a detailed tutorial on creating a powerful mini-computer using a Raspberry Pi. The total cost is around $225 (excluding the 3D printer or printing expenses). The project was developed by the Ruiz Brothers, who have shared all the necessary materials, including 3D-printable STL files. You can access the full guide online. This project may sound complex, but it’s actually quite manageable thanks to modern technology. The Raspberry Pi is a small, affordable computer—about $30 in price and roughly the size of a credit card. It can be connected directly to a monitor or TV, along with a keyboard and mouse. It handles tasks like playing HD videos, word processing, gaming, and web browsing. It's widely used by makers and is great for learning programming. The main components needed for this DIY project include a Raspberry Pi, power supply, display, and optional built-in audio. While the process involves some wiring and programming, the instructions from the Ruiz Brothers are thorough, and you can always seek help from the Adafruit community or meet other enthusiasts along the way. Regarding the 3D printing part, the shell design provided by the Ruiz Brothers is somewhat large. It may not fit on smaller 3D printers, such as the PrintrBot Simple. A printer with at least a 100 x 168 x 30 mm build area is recommended. Alternatively, you can use a third-party 3D printing service if you don’t have the right equipment. If you've ever dreamed of becoming a real maker, this project is a perfect starting point. It covers everything from planning and coding to electronics and 3D printing. It's a hands-on creation that develops essential skills for any aspiring tinkerer. The Ruiz Brothers have listed all the parts and tools you’ll need before starting. These can be purchased from Adafruit’s online store, including: - Adafruit DPI Display Kippah - Raspberry Pi 2 - Raspberry Pi B+ - 5-inch TFT display, 40-pin - PowerBoost 100C - PAM8302 amplifier - Thin plastic speaker - 2500mA lithium battery - Slide switch - Right angle 3.5mm stereo plug Tools and consumables include: - 3D printer - Wire - Wire stripper/knife - 30/26AWG cable - Soldering iron and solder - Panavise Jr. light vise - 6#2-56 3/8 flat head Phillips screws - 8#4-40 3/8 flat head Phillips screws - 1/4" to 3/8" threaded adapter Whether you're a beginner or an experienced maker, this project offers a rewarding blend of creativity, learning, and practicality.
