5 Clever Ways To Use Your Old Raspberry Pi As A Travel Companion

A Raspberry Pi might be the very last thing you’d assume to deliver on a visit, particularly when your bag is already filled with telephones, cameras, and different important devices. But you is likely to be shocked to find out how helpful this tiny laptop really is on the go. Designed for versatility and portability, the Raspberry Pi is light-weight however highly effective sufficient to deal with all kinds of travel-related duties. For occasion, it may well aid you again up your journey photographs and movies and provide you with instructions on the place to go with out requiring web connectivity.

If you are on the lookout for sudden sensible makes use of in your Raspberry Pi, we have rounded up 5 initiatives you possibly can tackle to take care of the Pi’s usefulness whereas on the transfer. From journey routers to transportable community connected storage (NAS) options, these nifty Raspberry Pi setups would possibly simply be what it is advisable to make your subsequent journey within the metropolis (or the wild) a complete lot smoother.

The final thing you need to occur when touring is in your baggage to go lacking. It’s irritating to take care of the airline’s reps, and you are not even certain when, and if, you may get your belongings again. For your peace of thoughts, take into account packing a baggage tracker together with your belongings. You haven’t got to purchase an costly one, although. If you have already got a Raspberry Pi mendacity round, you possibly can flip it into a wise baggage tracker in your travels — one of many many Raspberry Pi initiatives that may prevent cash.

A Pi-powered sensible baggage tracker is basically a GPS tracker that sends location updates through mobile community in actual time. To get the GPS knowledge, you will want a GPS module just like the Neo 6M. It makes use of satellite tv for pc alerts to find out the present latitude and longitude. Once you have got that knowledge, the Pi then must ship it to the cloud to get displayed. A SIM800L GSM module with a SIM card would work properly for this job. What it does is present mobile knowledge that lets the Pi connect with the web. For stronger reception, strive including antennas to the GPS and GSM modules.

Once within the cloud, the info will get displayed utilizing the free GeoLinker software by electronics web site Circuit Digest. GeoLinker creates an interactive map, the place the previous and present GPS knowledge are plotted in actual time to indicate a route. It’s accessible out of your browser, so you possibly can monitor your baggage simply. When the system goes offline, although, the GPS knowledge is saved domestically on the Pi for the interim. The board nonetheless uploads that saved location knowledge as quickly because the web connection is restored. You can choose to suit the parts in a compact case for handy attachment to your baggage.

During your journeys, you might need encountered lodging that cost per machine for Wi-Fi entry. This can put fairly a dent in your journey fund, particularly if you happen to’re with household or are utilizing your pill and laptop computer, on high of a number of telephones. Instead of paying for a raft of related gadgets, you possibly can simply use a journey router. It connects to the lodging’s Wi-Fi community after which broadcasts that connection in your different gadgets to make use of. This saves you cash, and even reduces privateness and safety dangers when on unsecure public Wi-Fi networks. While you possibly can simply purchase a journey router, a DIY one powered by Raspberry Pi can work simply as properly.

For this challenge, you will want any Raspberry Pi with an on-board Wi-Fi chip and a third-party USB community adapter that helps connection to a Raspberry Pi. The Pi’s on-board Wi-Fi will connect with your lodging’s community to achieve web entry, because it usually does. On the opposite hand, the exterior USB community adapter will function the hotspot in your different gadgets to hook up with. This setup is made doable utilizing wi-fi router software program like RaspAP. RaspAP permits the Pi board to operate as a Wi-Fi consumer (that connects to the community) and an entry level/router on the similar time.

Setting this challenge up is fairly easy. As quickly as you have got the Pi prepared, with the Raspberry Pi OS put in and the USB dongle inserted, you possibly can proceed with putting in RaspAP (or your most popular wi-fi router software program). Then, merely configure the software program — connect with the lodging Wi-Fi, change the hotspot SSID and password, and arrange a VPN and advert blocklist — through its net interface, and also you’re good to go.

Some locations you journey to will lack an web connection. Some types of public transportation do not provide free Wi-Fi, or a landmark you might go to is likely to be too distant for dependable cell service. Instead of relying in your cellphone for offline navigation, you need to use a Raspberry Pi-based offline GPS navigator to save lots of your cellphone’s battery — and your sense of course.

Just as you would possibly count on, what this offline GPS navigator does is aid you decide your present location on a map, even with out connecting to Wi-Fi or mobile knowledge. It’s powered by a GPS module just like the Reyax GNSS, which collects GPS data from a satellite tv for pc community and sends it to the Raspberry Pi. The Pi then shows your present location as a dot on the map. As you progress within the space, the map will get up to date together with your new location. This means you possibly can simply discover the realm with out worrying about getting misplaced. While the machine can work offline, the map must be downloaded and loaded onto the Pi first. It’s fairly much like the way you obtain offline maps on navigation apps like Google Maps for later use.

Hardware-wise, you possibly can technically use any Raspberry Pi for this challenge. But if you happen to’re seeking to make it light-weight, you would possibly need to go together with a smaller Pi board that additionally consumes much less energy — just like the Pi Zero 2. Any Pi-compatible display screen will do as properly, though an e-paper kind can be extra appropriate for out of doors use because it’s extra readable within the daylight. For portability, go together with a long-lasting battery to energy the challenge. For the software program, you will want data of terminal instructions, Python, and Flask.

When you are out on an journey, you are in all probability taking as many photographs and movies as you possibly can. But whereas snapping footage and recording clips, it is simply as vital to again them up — particularly if you happen to’re recording on an motion digicam or drone, the place the one copy you have got is on the SD card. A laptop computer works completely positive for backups, however to keep away from lugging it round, you possibly can simply make a journey NAS out of the extra transportable Raspberry Pi.

This setup requires just a few {hardware} parts: a Raspberry Pi, a big sufficient Pi-compatible exterior storage drive (for holding your footage and movies), and an SD card reader (if you happen to’re backing up an SD card). This makes the transportable NAS top-of-the-line fast and straightforward Raspberry Pi initiatives for brand new customers. To construct it, you need to use CasaOS, which basically features as a private server/dashboard and allows you to set up and handle net apps.

From right here, it is advisable to pair CasaOS with the free net app Syncthing. The latter software program syncs the folders on one machine (like your Pi) with a distant machine (like a NAS you already configured at house). That means something you add to your Pi will routinely be copied over to your at-home NAS in just some seconds. The system works through the web, so throughout backups, maintain your Pi related to Wi-Fi or cell knowledge. To make it much more handy to repeat recordsdata to the Pi itself, you possibly can run a script that routinely imports the contents of a USB drive/SD card reader to a Pi folder. This approach, you will not have to attach the board to a monitor, keyboard, and mouse.

Your cellphone already does a strong job at translating from one language to a different, letting you simply discuss to locals in another country. But what if you wish to save your cellphone’s battery for extra vital issues like making emergency calls? In that case, it is likely to be higher to make use of a separate translator machine — possibly one powered by a Raspberry Pi.

A Pi-based pocket language translator works like most translation apps on the market: It takes in what the speaker says, after which responds with the spoken translation. In the background, although, the method really takes 4 steps. First, the Pi data your voice and saves it as a WAV file. That means you will want a microphone related to the board. It’s faster to make use of a USB mannequin you could merely connect with one of many Pi’s USB ports. Next, the WAV file is transcribed into textual content with the SpeechRecognition Python library. That output textual content is what the Google Translate Python library then interprets into the goal language. Finally, the translated textual content is transformed again to speech utilizing Google Text-to-Speech and performed by means of the 5W audio system paired with the Pi. For clearer audio, you would possibly need to add an amplifier module like PAM8403.

The challenge contains two push button switches to manage the interpretation course. One button interprets from Language A to Language B, whereas the opposite does Language B to Language A. To let you already know what’s taking place behind the scenes, a show is related to the Pi. It relays the progress updates, similar to when the Pi continues to be recording, or whether or not it is performed changing the audio to textual content. The challenge runs on a 5V 2A energy provide, however you possibly can strive changing it with a battery for portability. Make certain you additionally connect with Wi-Fi or mobile knowledge, as the interpretation requires web entry.
