Ako ste poput mene, vjerojatno ste čuli za Raspberry Pi i kako se on može koristiti za izradu vlastitih DIY projekata poput postavljanja kućnog medijskog poslužitelja ili upravljanja robotom ili praćenja vremena. Ako se volite petljati oko elektronike, Raspberry Pi je izvrsno polazište za početnike ili napredne korisnike.

Ako ste inženjer elektrotehnike, vjerojatno već znate kakav Raspberry Pi kupiti, kako ga postaviti, programirati itd. Ako ste štreber poput mene, ali se nikada niste petljali s nečim poput Raspberryja Pi^{(Raspberry Pi)} ili Arduino , izbor može biti malo zbunjujući.

Koji Raspberry Pi kupiti?

Ovo neće biti opsežna usporedba modela jer već postoji mnogo stranica koje su obrađivale tu temu. Umjesto toga, rastaviti ću ga na vrlo jednostavne pojmove. Od danas, ako pogledate službenu stranicu Raspberry Pi^{(Raspberry Pi website)} , imate sljedeće modele:

Najnoviji i najsposobniji Raspberry Pi proizvod je Raspberry Pi 3 Model B , koji je objavljen u veljači^(February) 2016. Prethodni model bio je Raspberry Pi 2 Model B , koji je objavljen u veljači^(February) 2015. Postoje samo tri razlike između Pi 3 i Pi 2 model B :

1. Verzija sustava na čipu (SoC).
2. 1,2 GHz 64-bitni četverojezgreni ARM Cortex-A53 na Pi 3 u odnosu na 900 MHz četverojezgreni ARM Cortex-A7 na Pi 2
3. 802.11n bežični i Bluetooth 4.1 na Pi 3

Sve ostalo je potpuno isto, uključujući i cijenu! Pi 1 Model Model A+ objavljen je u studenom^(November) 2014. i još uvijek se koristi jer je uređaj vrlo male potrošnje, što je uvjet za neke vrste projekata. Raspberry Pi Zero , Sense Hat i Compute Module su svi namijenjeni industrijskim aplikacijama ili naprednim hobistima.

Dakle, u osnovi, po mom mišljenju, ako ste novi u Raspberry Pi i DIY projektima općenito, najbolja opcija je Raspberry Pi 3 Model B jer košta isto kao Pi 2 Model B , ali je mnogo brži i ima više tehnologije na ploči.

Također je najjednostavniji za početak u smislu postavljanja i jednostavnosti korištenja. Ploča sama po sebi košta 35 dolara, ali to je samo ploča i doslovno ništa drugo, čak ni napajanje.

Raspberry Pi Kit vs No Kit

Opet, ako znate što radite, kupnja ploče može biti sve što vam treba. Međutim, ako nemate pojma kako započeti s jednom od ovih ploča, poput mene, možda bi bilo vrijedno potrošiti nešto dodatnog novca i kupiti komplet.

Sada ako tražite Raspberry Pi 3 komplete na mreži, dobit ćete hrpu rezultata u rasponu od 60 do 150 dolara. To je zato što postoji sve, od početnog kompleta do kompleta za medijski centar do kompleta za kameru do kita za vremensku prognozu. Dakle, koju biste trebali kupiti?

Pa, ako želite potrošiti najmanje novca, a nemate pojma kakav projekt želite pokrenuti, onda predlažem kupnju samo početnog kompleta. Svi početni setovi uglavnom dolaze s istim bitnim dijelovima:

• Raspberry Pi 3 model B ploča
• 1 microSD kartica s prethodno učitanim NOOBS-om
• 1 kućište
• 1 napajanje
• 1 HDMI kabel (ne svi kompleti)

Nakon toga, to stvarno ovisi o početnom kompletu ili pakiranju. Neki su malo skuplji i dolaze s cijelom hrpom drugih dijelova poput matične ploče ili žica za kratkospojnike. Ako planirate kupiti komplet, evo moje četiri preporuke od najjeftinije do najskuplje:

1. 59,99 USD – MCM Raspberry Pi 3 početni komplet^{(MCM Raspberry Pi 3 Starter Kit)}
2. 69,99 USD – Virlos Raspberry Pi 3 Kompletan početni komplet^{(Virlos Raspberry Pi 3 Complete Starter Kit)}
3. 74,99 USD – kompletan početni komplet CanaKit Raspberry Pi 3^{(CanaKit Raspberry Pi 3 Complete Starter Kit)}
4. 99,99 USD – Početni paket Adafruit Raspberry Pi 3 Model B^{(Adafruit Raspberry Pi 3 Model B Starter Pack)}

Za mene sam na kraju uzeo Vilros Starter Kit jer je također uključivao kvalitetan HDMI kabel i dva aluminijska hladnjaka.

Kako postaviti Raspberry Pi 3 model B

Kada dobijete svoj komplet, idemo dalje i postaviti ga. Prvo^(First) otvorite paket i izvadite sav sadržaj. Ovdje je moj početni paket s pločom i priborom.

Prva stvar koju želimo učiniti je instalirati dva hladnjaka na vašu Pi 3 ploču. Imajte na umu da nije uvjet za korištenje hladnjaka i mnogi kompleti ih čak i ne uključuju. Međutim, ako planirate održavati svoju ploču u radu tijekom duljeg vremenskog razdoblja dok obavljate intenzivne CPU ili grafičke zadatke, hladnjak će smanjiti mogućnost pregrijavanja ploče.

Iznad^(Above) je pogled izbliza na Pi 3 ploču. Za ugradnju hladnjaka, samo odlijepite traku na dnu i zalijepite ih prema priloženim uputama. Za referencu, evo kako izgleda moja ploča s dva instalirana hladnjaka.

Nakon toga trebate izvaditi microSD karticu i umetnuti je u utor koji se nalazi na dnu ploče na suprotnoj strani od USB i Ethernet portova. To je mali utor, stoga budite oprezni pri umetanju kartice.

Zatim moramo staviti Pi 3 u priloženo kućište. Ovisno o vrsti kućišta koja dolazi s vašim kompletom, upute će obično biti u zasebnom dokumentu. U mom slučaju s Vilros kućištem, morao sam ga otvoriti i zatim umetnuti ploču u donji dio kao što je prikazano ispod.

Nakon toga sam stavila s dvije strane pa poklopac na vrhu. Nakon što je vaša ploča sigurno u kućištu, možemo početi spajati kabele na nju. U osnovi postoji pet stvari koje je potrebno spojiti: USB tipkovnica, USB miš, HDMI kabel, Wi-Fi ili Ethernet i kabel za napajanje. Vrijedi napomenuti da ako imate SD karticu s NOOBS-om^(NOOBS) , zapravo ne morate biti povezani s internetom^(Internet) .

Dakle, što je NOOBS? To je skraćenica od New Out Of Box Softwar e i u osnovi čini instalaciju operativnog sustava na vaš Pi 3 stvarno jednostavnom. Uskoro ću o tome. Prvo^(First) , ovdje je moj Pi 3 spojen i spreman za uključivanje.

Imajte na umu da će se Pi 3^{(Pi 3)} odmah uključiti kada uključite napajanje, pa to učinite zadnjim. Također, provjerite je li monitor postavljen na ispravan HDMI ulaz. Ako vaša ploča nije slomljena ili oštećena, nakon nekoliko trenutaka trebali biste vidjeti sljedeći zaslon NOOBS .

Imate nekoliko opcija kada je u pitanju instaliranje OS-a na svoj Pi 3 . Raspbian je Linux operativni sustav temeljen na Debianu, ali optimiziran za Raspberry Pi . Kodi Entertainment Center je softverski paket otvorenog koda za kućno kino, a OSMC je medijski centar otvorenog koda. Ako želite koristiti svoj novi Pi 3 kao mali prijenosnik medija za streaming povezan s vašim HDTV -om , odaberite bilo koji od njih.

Lijepa stvar kod NOOBS- a je da ostaje na vašoj SD kartici čak i nakon što instalirate operativni sustav. Kada dižete Pi, samo držite pritisnutu tipku SHIFT kako biste ponovno otvorili NOOBS^(NOOBS) izbornik. Možete jednostavno instalirati drugi operativni sustav kad god želite. Stoga slobodno testirajte stvari i ne brinite da ćete u početku napraviti pogrešan odabir.

U mom slučaju, želim na kraju pokušati programirati svoj Pi, pa sam instalirao Raspbian, iako možete instalirati i Windows 10 IoT Core , ako ste Windows osoba.

Može potrajati neko vrijeme da se operativni sustav instalira zbog brzine prijenosa podataka. Nakon^(Once) dovršetka, uređaj će se ponovno pokrenuti i pokrenuti operativni sustav koji ste instalirali. Kod mene je sve prošlo dobro i bio sam na Raspbian desktopu oko 45 minuta nakon što sam uključio svoj Pi 3 .

Radna površina je vrlo jednostavna i laka za korištenje. Postoji gumb pod nazivom Izbornik^(Menu) koji vam omogućuje pregledavanje instaliranih aplikacija i konfiguriranje postavki. Pored toga je gumb web preglednika, gumb za upravljanje datotekama i gumb Terminal . Ovaj post je bio uvod i samo je trebao da vas pokrene s novim Pi 3 . Budući postovi pokrivat će naprednije teme dok ih ja istražujem! Ako imate pitanja, slobodno komentirajte. Uživati!

How to Get Started with the Raspberry Pi 3 Model B

If you’re like me, you’ve probably heard of Raspberry Pi and how іt can be usеd to create your own DIΥ projects like setting up a home media server or controlling a robot or monitoring the weather. If you like to tinker around wіth electronics, Raspberry Pi is a great starting point for beginners or advanced users.

If you’re an electrical engineer, you probably already know what to kind of Raspberry Pi to buy, how to set it up, program it, etc. If you’re a geek like me, but have never messed around with anything like Raspberry Pi or Arduino, the choice can be a little more confusing.

Which Raspberry Pi to Buy?

This is not going to be an extensive comparison of the models because there are already a lot of sites that have covered that topic. Instead, I’ll break it down into very simple terms. As of today, if you look at the official Raspberry Pi website, you have the following models:

The newest and most capable Raspberry Pi product is the Raspberry Pi 3 Model B, which was released in February of 2016. The previous model was the Raspberry Pi 2 Model B, which was release in February of 2015. There are only three differences between the Pi 3 and Pi 2 Model B:

1. System on a Chip (SoC) Version
2. 1.2 GHz 64-bit quad-core ARM Cortex-A53 on Pi 3 vs 900 MHz quad-core ARM Cortex-A7 on Pi 2
3. 802.11n wireless and Bluetooth 4.1 on Pi 3

Everything else is exactly the same, including the price! The Pi 1 Model A+ was released in November of 2014 and is still used because it is a very low-power device, which is a requirement for some types of projects. The Raspberry Pi Zero, Sense Hat and Compute Module are all geared to industrial applications or advanced hobbyists.

So basically, in my opinion, if you are new to Raspberry Pi and DIY projects in general, the best option is the Raspberry Pi 3 Model B because it costs the same as the Pi 2 Model B, but is much faster and has more tech on the board.

It’s also the easiest to get started with in terms of setup and ease of use. The board by itself costs $35, but it’s only the board and literally nothing else, not even a power supply.

Raspberry Pi Kit vs No Kit

Again, if you know what you’re doing, buying the board may be all you need. However, if you have no clue how to get started with one of these boards, like me, then it might be worth spending some extra money and purchasing a kit.

Now if you search for Raspberry Pi 3 kits online, you’ll get a bunch of results ranging from $60 to $150. That’s because there is everything from a starter kit to a media center kit to a camera kit to a weather kit. So which one should you buy?

Well, if you want to spend the least amount of money and you have no idea what kind of project you want to start, then I suggest purchasing only a starter kit. All starter kits pretty much come with the same essential parts:

• Raspberry Pi 3 Model B board
• 1 microSD card with NOOBS preloaded
• 1 enclosure
• 1 power supply
• 1 HDMI cable (not all kits)

After that, it really depends on the starter kit or pack. Some are a bit more expensive and come with a whole bunch of other parts like a breadboard or jumper wires. If you plan on purchasing a kit, here are my four recommendations from cheapest to most expensive:

1. $59.99 – MCM Raspberry Pi 3 Starter Kit
2. $69.99 – Virlos Raspberry Pi 3 Complete Starter Kit
3. $74.99 – CanaKit Raspberry Pi 3 Complete Starter Kit
4. $99.99 – Adafruit Raspberry Pi 3 Model B Starter Pack

For me, I ended up going with the Vilros Starter Kit because it also included a good quality HDMI cable and two aluminum heat sinks.

How to Setup a Raspberry Pi 3 Model B

Once you get your kit, let’s go ahead and set it up. First, open the package and take out all of the contents. Here is my starter pack with the board and accessories.

The first thing we want to do is install the two heat sinks onto your Pi 3 board. Note that it’s not a requirement to use heat sinks and a lot of the kits don’t even include them. However, if you plan to keep your board running for long periods of time while performing intensive CPU or graphical tasks, then the heat sinks will reduce the chance of the board overheating.

Above is a close up look at the Pi 3 board. To install the heat sinks, just peel off the tape at the bottom and stick them on according to the instructions provided. For reference, here is what my board looks like with the two heat sinks installed.

After this, you should take out the microSD card and insert it into the slot, which is located on the bottom of the board on the opposite side of the USB and Ethernet ports. It’s a tiny slot, so be careful when inserting the card.

Next, we need to put the Pi 3 into the provided enclosure. Depending on what type of enclosure comes with your kit, the instructions will normally be in a separate document. In my case with the Vilros enclosure, I had to open it and then insert the board in the bottom section as shown below.

After that, I put on the two sides and then the cover at the top. Once your board is safely in the enclosure, we can start connecting cables to it. There are basically five things that need to be connected: a USB keyboard, a USB mouse, an HDMI cable, Wi-Fi or Ethernet and the power cable. It’s worth noting that if you have an SD card with NOOBS, you don’t really have to be connected to the Internet.

So what is NOOBS? It stands for New Out Of Box Software and it basically makes installing an operating system onto your Pi 3 really easy. I’ll talk about that shortly. First, here is my Pi 3 connected and ready to be powered on.

Note that once you plug in the power, the Pi 3 will turn on immediately, so make sure you do that last. Also, make sure that the monitor is set to the correct HDMI input. If your board isn’t broken or damaged, you should see the following NOOBS screen after a few moments.

You have a couple of options when it comes to installing an OS on your Pi 3. Raspbian is a Linux operating system based on Debian, but optimized for the Raspberry Pi. Kodi Entertainment Center is an open source home theater software package and OSMC is an open source media center. If you want to use your new Pi 3 as a tiny media streaming box connected to your HDTV, then choose either one of those.

The nice thing about NOOBS is that it remains on your SD card even after you install an operating system. When booting up the Pi, just hold down the SHIFT key to bring up the NOOBS menu again. You can easily install another operating system whenever you like. So feel free to test stuff out and don’t worry about making the wrong choice in the beginning.

In my case, I want to eventually try to program my Pi, so I installed Raspbian, though you can also install Windows 10 IoT Core, if you are a Windows person.

It might take a while for the operating system to install because of the data transfer speed. Once complete, the device will restart and boot into the operating system you installed. All went well on mine and I was on the Raspbian desktop about 45 minutes after powering up my Pi 3.

The desktop is very simple and easy to use. There is a button called Menu that lets you browse installed applications and configure settings. Next to that is a web browser button, file manager button and Terminal button. This post was an introduction and only meant to get you up and running with a new Pi 3. Future posts will cover more advanced topics as I explore them myself! If you have any questions, feel free to comment. Enjoy!
