October 24, 2014 at 16:47Raspberry Pi - what can be done on the basis of “raspberry”?
Raspberry Pi mini-PC was able to quickly become a popular platform for various projects - both commercial and not so. There are several reasons for this, among which are the low price of the computer, its relative universality and openness.
As a result, interesting projects began to appear with enviable regularity, and some of these projects are presented in this collection. There are quite serious systems, and projects that can be called entertaining, from the series “why not?”.
Supercomputer based on Raspberry Pi and Lego
One of the most interesting raspberry-based projects is a supercomputer of 64 Raspberry Pi. As elements for creating "server cabinets", the usual Lego constructor was used.
As ROM for this system, SD memory cards of 16 GB were used. Such cards were installed in each "raspberry".
How to do something like this? Detailed instructions from the creator, professor of the University of Southampton Simon Cox - at this link .
Pi-based weather balloon
Computer enthusiast Dave Ackerman decided to use his own mini-PC to create a weather balloon, with the possibility of obtaining photos from the stratosphere. Detailed report here .
After several months of work, Dave was really able to launch his probe, which flew over 30 kilometers, worked at temperatures of -50C in a very rarefied atmosphere (1% of the standard).
The probe recorded all the necessary parameters, including temperature, humidity, density, altitude. The coordinates were also fixed. Among other things, the camera was also used, with the help of which it was possible to get many excellent pictures.
Internet phone
Based on the “raspberry”, a regular landline telephone with a disk dialer was improved. Instead of the usual board, the developer installed the Raspberry Pi.
After a series of manipulations, the developer managed to create a Skype-phone as a stand-alone device, without the need to use a connection to a regular computer.
Here's how it looks and works:
Game station
This is the wabakabobik user’s project . An interesting device that allows you to play a number of old games for a large number of consoles, including NES, SNES, Sega Genesis, PlayStation, as well as SCUMMVM, zxspectrum.
The author wrote that "the entire system is based on the RetroArch port, based on the libretro library, which allows the use of emulators of various consoles." As for the graphical shell, we used EmulationStation , also RetroPie .
Raspberry based tablet
This tablet has an interesting name - PiPad, and wood was used as the material for the case. It all looks like this: The
tablet’s display diagonal is 10 inches. Well, all the other characteristics coincide with those of the raspberry itself. True, there is no longer a couple of hours of work, but thorough work. Detailed instructions for creating a tablet based on the "raspberry" inside .
The OS used is Raspbian Linux with XBMC.
Wall calendar organizer
Instructables user with the nickname Piney created a useful gadget for himself - an interactive wall calendar, with the ability to add tasks and events.
The software platform is the regular Google Calendar, all the data from which is broadcast via WiFi to this wall-mounted device.
Detailed instructions on how to create something like this - here .
Own radio station
I don’t know how legal this is, but the project is really interesting. Dedicated to those who always wanted to become a DJ at their own radio station.
True, the coverage of such a radio station is relatively small: an area equal to the area of the stadium.
DVD changer
The person who created this thing just got tired of constantly changing DVDs. As a result, this project appeared, which was done simply because it could be done. Why not?
Lighting System for Christmas
Before the New Year and Christmas there is not much time left, therefore, if there is an extra "raspberry", you can create a lighting system for your own house or apartment. How to make such a system is described here . And below is a video showing how it works.
In general, the scope of use of the Raspberry Pi is very wide, much wider than the creation of photo frames and laptops. Developers are trying to improve their device by releasing new, updated versions of the mini-PC and additional modules for it. For example, the Raspberry Pi B + came out in the summer , the other day the company introduced a display for the raspberry . And after some time (unfortunately, it is impossible to say more definitely), the release of the Raspberry Pi A + is also planned.
