7 Awesome Uses for an Old SD Card
Do you have any old SD cards or microSD cards (with a suitable adaptor) lying around? If so, don’t throw them away – there are plenty of projects that you can complete with these compact flash storage devices.
Whether your old SD card is a meager 64 MB or a massive 64 GB, various projects exist for you to make use of these storage cards. Smaller cards may be used as portable media storage, printing from SD and building a digital photo frame. Larger cards, meanwhile, might be used for providing emergency boot support to your PC, modding a Nintendo Wii or even installing CyanogenMod on your Android device.
Emergency Boot Device
Perhaps the most important use you can find for an old SD card is as an emergency boot device, to assist with problems when your computer won’t start up.
Now, you’re probably thinking to yourself, “Hold on, these links are for USB flash drives,” and you would be right. However, with a device like this one below, you can turn your old SD card into a USB stick, something that proves pretty useful in a number of different situations.
Portable Media Storage
The more space you have on your spare or old SD card, the more suited it will be for various multimedia-related projects.
One popular use is to store your favourite photos on it, and view them on a suitable digital photo frame. You might even use the card to install an operating system and add photos, ready to be used in a custom-built digital photo frame, one that perhaps started life as a notebook or netbook.
If you use a digital camera, you might use a spare SD card as a means of quickly checking your photos on your phone or tablet (assuming you have a suitable card reader).
There are also a couple of ways in which an old SD card can be used to create a media centre…
Softmod A Nintendo Wii
Using an SD card with the useful Letterbomb software installed, you can softmod your Nintendo Wii to allow various homebrew software applications to run.
You might, for instance, use the device as a DVD player (standard DVDs cannot be read as standard by the Nintendo Wii; this mod will work on the older models, however), or to play homebrew and retro games.
Alternatively, you can use the mod to turn your Wii into a media centre , capable of playing movies from your SD card or a storage device on your local network.
Print from SD
Another use for an old SD card is printing. You don’t need to have a wireless card or a wireless printer to send print jobs over your Wi-Fi network – you could just save the job to be printed to the SD card and then use your printer’s card reader (assuming it has one) to find the file that needs printing and begin the print job.
Depending on the printer, this will probably work universally for images – although some printers can print documents without a connected computer. If you have any local photo printing booths that accept SD cards, this is a useful thing to be aware of.
Run a Raspberry Pi
Do you own a Raspberry Pi? If so, you’ll probably be aware that an SD card is required as the primary boot device, and can also be used for storage.
With multiple storage devices you can have access to different operating systems, customised for particular projects; you might, for instance, have RaspBMC installed to use the little computer as a media centre, or a RetroPIE installation for retro gaming .
The Raspberry Pi can be used for so much more, however; who would have thought that an SD card could form part of a low budget space programme ?
GPS Expansion Card
If you regularly use your GPS device for travel and have found it seemingly running out of space, you might use the expansion slot to provide the space you need to download new maps and voices.
Surprisingly, GPS systems are still widely used as distinct units, as opposed to the various smartphone-based systems such as Google Maps and Nokia HERE.
Given the price of a new GPS unit, it makes sense to get as much use as possible out of these devices, so if you have a suitable slot for your SD card or microSD card, this might be a great way to solve two problems at once.
Install CyanogenMod On Your Android Device
Finally, if you’re using an Android phone or tablet and are less than happy with the installed version of the popular mobile operating system, you might take advantage of your SD card or microSD card (depending on the size of the card reader slot) to change this.
Perhaps the most popular alternative to stock Android is CyanogenMod , and you’ll find the details for installing this to your Android device (the initial steps for which often require a one-time installation to your SD card) by searching for the appropriate hardware on a site such as XDA-developers.com.
