Every Raspberry Pi in\u00a0the cluster<\/h2>\n

\"\"<\/a>Here are the 7 initial Pi’s that are to become part of the cluster. Each have been given a codename to designate\u00a0its position in the cluster.\u00a0The Raspberry Pi designed “M” will be the initial master Raspberry Pi as this is a Raspberry Pi 1 B+. Nodes 1 to 4 are all Raspberry Pi 1 revision 1.2 (512 MB version). The unlabelled one with the blue SD card is “chewpi” the original Raspberry Pi I have been using. This is again a Raspberry Pi revision 1.2 (512 MB). The final node, Node 5, is an original Raspberry Pi 1 (256 MB) which wont sit in the cluster stack but will be joined eventually.<\/p>\n

Shots of casing assembly<\/h2>\n

\"\"<\/a><\/p>\n

Here you can see the master node sitting in its casing. I have decided to mount this one at the top for ease of accessing its USB ports.<\/p>\n

\"\"<\/a><\/p>\n

Here you can see the modifications to the casing means that I am able to easily stack the older Raspberry Pi’s with the newer ones with the mounting holes.\u00a0I described how to modify the case in an earlier post.<\/p>\n

The open sides of the case should allow for good ventilation as when the Raspberry Pi’s are running they are expected to generate some heat.<\/p>\n

\"\"<\/a><\/p>\n

Here the final cluster sits in all its glory. In this configuration all the needed ports (power, USB and Ethernet) are accessible out the side of the case. If I want to access some of the GPIO ports I may convert the cluster into several stacks of 2 or 3. However I wont be doing this initially as this suites current my purposes fine.<\/p>\n","protected":false},"excerpt":{"rendered":"
