You found it! Stuck in the back of your craft box, a Raspberry Pi Model A or B that you put away years ago, possibly when the Raspberry Pi 2 was released. Since then, he has done nothing, his time has passed.
Or is there?
Just like an old computer, you can still get great results from an old Raspberry Pi. Here are some ways you can use your old Raspberry Pi Model A or B.
Limits of older Raspberry Pi models
While you won’t be able to run Windows 10 IoT, there’s still a lot you can do with an old, forgotten Raspberry Pi.
But don’t get carried away: the 2012 version of the Raspberry Pi has a modest 700MHz single-core processor and 256MB of RAM. GPIO is smaller too.
Also, you need to think about improving your peripherals. The new power adapter will provide reliable power to the device, avoiding unnecessary freezes and restarts. Similarly, you will need a good quality SD card to store the operating system.
You won’t be streaming high-definition video or playing Dreamcast games on a Retropie with a first generation Raspberry Pi, but you can still have fun and maybe learn something new.
1. Run the latest version of Raspbian
Most of the same features are also available, with the exception of a few hidden options (such as USB boot and PXE boot). To use the latest version of Raspbian (rather than leaving the old install running), it’s probably best to use a fresh install on an existing SD card.
Alternatively, you can run an update from:
sudo apt update sudo apt dist-upgrade
Wait for the latest version of Raspbian to download and install, then reboot when you’re done.
Alternatively, try a really lightweight OS like piCore, a build of TinyCore Linux for the Raspberry Pi. This can help you manage the limited resources of your old Raspberry Pi more efficiently.
2. Camera home security system
With a low spec Raspberry Pi computer, you can even build a motion detection security camera. While there is a dedicated Raspberry Pi Camera module that you can use, many USB cameras are also compatible.
The result is a system that will detect motion and record the results, ready to be reviewed later. Note that a network connection is desirable for this project, so make sure you have a Wi-Fi dongle or ethernet cable.
