| Titre | Some notes on the Raspberry Pi |
| Texte | I keep seeing this article in my timeline today about the Raspberry Pi. I thought I'd write up some notes about it.The Raspberry Pi costs $35 for the board, but to achieve a fully functional system, you'll need to add a power supply, storage, and heatsink, which ends up costing around $70 for the full system. At that price range, there are lots of alternatives. For example, you can get a fully function $99 Windows x86 PC, that's just as small and consumes less electrical power.There are a ton of Raspberry Pi competitors, often cheaper with better hardware, such as a Odroid-C2, Rock64, Nano Pi, Orange Pi, and so on. There are also a bunch of "Android TV boxes" running roughly the same hardware for cheaper prices, that you can wipe and reinstall Linux on. You can also acquire Android phones for $40.However, while "better" technically, the alternatives all suffer from the fact that the Raspberry Pi is better supported -- vastly better supported. The ecosystem of ARM products focuses on getting Android to work, and does poorly at getting generic Linux working. The Raspberry Pi has the worst, most out-of-date hardware, of any of its competitors, but I'm not sure I can wholly recommend any competitor, as they simply don't have the level of support the Raspberry Pi does. The defining feature of the Raspberry Pi isn't that it's a small/cheap computer, but that it's a computer with a bunch of GPIO pins. When you look at the board, it doesn't just have the recognizable HDMI, Ethernet, and USB connectors, but also has 40 raw pins strung out across the top of the board. There's also a couple extra connectors for cameras.The concept wasn't simply that of a generic computer, but a maker device, for robot servos, temperature and weather measurements, cameras for a telescope, controlling christmas light displays, and so on.I think this is underemphasized in the above story. The reason it finds use in the factories is because they have the same sorts of needs for controlling things that maker kids do. A lot of industrial needs can be satisfied by a teenager buying $50 of hardware off Adafruit and writing a few Python scripts.On the other hand, support for industrial uses is nearly nonexistant. The reason commercial products cost $1000 is because somebody will answer your phone, unlike the teenager whose currently out at the movies with their friends. However, with more and more people having experience with the Raspberry Pi, presumably you'll be able to hire generic consultants soon that can maintain th |
