Raspberry Pi 3 And The Small Computer That Keeps Growing

The first Raspberry Pi was exciting because it made a computer feel inexpensive enough to experiment with. The new Raspberry Pi 3 continues that idea, but the small board is becoming much more capable. A faster processor, built-in Wi-Fi, and Bluetooth make it easier to use without adding several external devices.

I still think the most important feature is not performance. It is permission to experiment. A normal laptop contains important documents, accounts, and daily work. We usually do not want to turn it into a strange hardware project. A small board creates a different feeling. If the operating system breaks, we can rewrite the memory card and begin again.

This makes the Raspberry Pi especially useful for education. Students can learn Linux, programming, networking, and electronics on the same device. A Python program can read a sensor or control an LED. A small web server can run beside a simple robot project. The distance between software and physical computing becomes very short.

The growing power of the board also creates a small danger. It is easy to turn the Raspberry Pi into only a cheap desktop computer and forget why it became interesting. The GPIO pins and the ability to connect the machine to the physical world are part of its personality.

I like computers that invite us to open them, connect things, and make mistakes. Many modern devices are becoming more polished and more closed at the same time. The Raspberry Pi moves in another direction.

A small computer can be useful because it is not precious. Sometimes learning becomes easier when we are not afraid of breaking the machine.
