Raspberry Pi 4 project: Build a $100 PC - hillcating

For a short patc, PC building was gloriously affordable. The monetary value of graphics card game and RAM at length dropped afterward 2018's dark times, AMD unbroken cramming more cores into its CPU lineup without increasing prices, and SSDs could make up had for a bargain price.

Nowadays building a basic x86 PC is pretty expensive. Overwhelming demand, tighter supply, and tariffs mean that, compared to last year, you'll spend $10 more here and $15 more there across the display board—even as much American Samoa $40 more on a great power cater. It adds high to a steep increase for those WHO only browse the web, watch streaming videos, edit documents, and/or codification.

Fortunately, you can sidestep that financial outlay with an alternative: the base merely right Raspberry Private detective 4. This fourth-generation translation of the popular divorced-card computer starts at just $35 and packs enough punch to easily deal everyday tasks. Moreover, its simplicity substance building is ultra fast. We put together a Linux-supported desktop system for meet over $100 and in about an hour, including software installs.

Parts list

Actual street prices listed in parenthesis.

Bir Private detective 4 (Model B)

4GB version, $55 MSRP ($61)

raspberry pi 4 board — The Raspberry Pi 4 gameboard sports a quadrangle-core 1.5GHz Cortex-A72 processor; 2GB, 4GB, or 8GB LPDDR4 RAM; dual-band Wisconsin-Fi; Bluetooth 5.0; and gigabit ethernet, 2x micro-HDMI, 2x USB 3.0, 2x USB 2.0 ports, on with a 3.5mm linear jack.

The Raspberry Pi 4 has nearly all the elements you need for a PC built rightist in. The processor, art, RAM, Wi-Fi, Bluetooth, USB ports, ethernet, and HDMI are part of the board; you only need to provide power, storage, and (ideally) a case.

Three variants of the Raspberry Pi 4 exist—2GB RAM, 4GB RAM, and 8GB Jampack. The other spectacles remain the same, alike the quadriceps-center 1.5GHz Build up CPU and numeral of ports. We chose the $55 4GB version for this project, as it's a good balance between price and performance. The $35 2GB option works equally asymptomatic, but it will reduce the number of windows or browser tabs you can have undisguised and the build's ability to meet greater performance demands down the road.

MicroSD card (32GB)

16GB microSD card ($6) -OR-
16GB microSD card with NOOBS preinstalled ($15)

Our recommendation of a 16GB microSD card assumes you process both cloud-based and local documents. If you'll skew toward the latter and relieve many a large files to the system, consider a 32GB or large tease as needed.

Purchase a standard blank microSD posting if you have access to an alive Windows, Macintosh, or Linux computer and don't mind installing Raspberry Pi OS (antecedently known as Raspbian) yourself. Otherwise, buy up same that has NOOBS ("Untried Prohibited of the Box Software," a Raspberry Pi-specific OS installer) preinstalled on the microSD card

Heat sinks

2-pack, various sizes ($4) -or as part of… –
Slip / heat sinks / power supply kit ($15)

Heat sinks help dissipate heat from the Raspberry Pi 4's board and allow you to avoid performance issues related to overheating on warmer years. You don't even have to worry about messy thermal paste, thanks to viscous thermal pads. Just peel and stick.

You can choose to buy these a la carte or as part of an overall kit—go with the option that ends up cheapest for you given the supplies you already own (i.e., a spare 5V 3A smartphone charger).

Power supply

CanaKit Bronx cheer Pi 4 power supply ($10) -or American Samoa part of… –
Case / heat sinks / power add kit ($15)

The Raspberry Pi 4 accepts any USB-C exponent supplying that outputs 5 volts at 3 amps (5V 3A). That includes any smartphone chargers that run across these spectacles. If you need to buy up a top executive supply, we suggest buying it in a bundle or kit that as wel includes heat sinks and a case, to save money—you plausibly South Korean won't already have the last mentioned two items already available.

Short letter : To turn inactive the Snort Pi 4, you accept to unplug IT from the outlet. For convenience's sake, you may regard to purchase a office provision with an connected/off release or add happening a $6 outlet great power electric switch to unrivalled you already possess.

Case

MazerPi Raspberry Pi 4 case ($9) -operating theater As part of… –
Case / heat sinks / ability supply kit ($15)

To be precise, a case is nonmandatory for a Raspberry Pi, but using one will protect your board from dust, pet hairsbreadth, and some other hazards.

Uncounted options exist, ranging from simple $10 models with fans to fancy $25-plus enclosures made of laser-snub wood. We corresponding cases that attach to a sports fan—because Raspberry Pi boards want active cooling system, adding a casing restricts airflow. That fan summation adhesive heat sinks happening the RPi itself will protect against performance issues along warmer years.

Operating scheme

Raspberry Pi OS ($0)

Raspberry Pi Foundation

Based connected the Debian distro of Linux, Raspberry Pi Oculus sinister is a version of Debian 10 ("Baby buster") optimized for the Raspberry Principal investigator. Though you can install new operational systems onto your Raspberry Pi 4, we have to stick to Raspberry PI Atomic number 76 for this material body to to the full work equally a basic productivity Personal computer.

During setup, you'll install the full version of Hiss Pi OS, which drops even more than popular free desktop applications onto your system than the standard rendering of the OS does. Boss among them is LibreOffice, an ASCII text file computer software alternative to Microsoft Office. If you'Re in a travel rapidly and you put on't be after to edit some .docx, .xlsx, or other Office documents on the Hoot Pi itself, you can save or s clock and install the monetary standard version of Bir Pi OS instead. (You can forever install LibreOffice later.)

Note: Until recently, Raspberry Pi OS was known as Raspbian—so if you're other to this operating organisation and are looking for guides or troubleshooting assist, you can use the cardinal terms fairly interchangeably in search queries.

Keyboard and mouse

Basic wired 104-key keyboard ($8)
Basic connected 2-button mouse ($7)

These options are extremely basic, but they get the job done. You May be able to perk these for free done Craigslist, your local Freecycle grouping, or the /r/hardwareswap subreddit—oftentimes masses replace prebuilt computers' included keyboards and mice with more expensive power train.

Small-HDMI cable (or adapter)

Micro-HDMI to HDMI adapter ($7) -operating room-
Micro-HDMI to HDMI cable ($10)

To accommodate the Raspberry Pi 4's new endorse for multiple-monitor output, the respective HDMI port on the Bir Pi 3 got scrapped in favor of two small-HDMI ports. Accordingly, you'll need to buy a micro-HDMI to HDMI line, or an adapter for a standardized HDMI cable you already own.

Be aware that most adapters are too wide to correspond side-by-side, so if you plan to consumption cardinal monitors simultaneously with your Raspberry Pi PC, you'll need to buy two of the specialty cables.

Monitor

Freebee ($0)

Even in this time of COVID-19, you toilet bump the occasional free monitor available through sites like Craigslist, Freecycle, section swop sites, and the /r/hardwareswap subreddit.

If you have to bargain a monitor, your easiest cheesy option is a softly used indefinite from a goody-goody friend or family appendage. The next-outflank options are trusted companies selling via eBay with free shipping (e.g., HP, Acer, High-grade Grease one's palms, etc), or finding a great sale direct Newegg's newsletter, the /r/buildapcsales subreddit, and/or Slickdeals.net.

A 23-inch IPS 1080p monitor should carry between $75 to $90 connected sale these days. We've also seen 21-inch VA 1080p monitors A low Eastern Samoa $65 on sales agreement inside the last hardly a weeks.

Setup

OS / computer hardware

OS installation time: Upfield to 45 min Hardware gathering: 5 to 10 min Initial frame-up wizardly: 10 to 20 min

Assembling a Razz Pi system goes very fast—it's the operational organisation installation that consumes to the highest degree of the setup clock time. Fortunately, you don't need to babysit the process and can do other things while you await for the install to finish.

Raspberry Pi 4 with cables plugged in — You can run the Raspberry Pi 4 without causa, but we recommend using one to protect it from dust, pet hair, and other hazards.

If starting with a blank microSD card, habit the Raspberry Pi Imager application to install the full version* of Raspberry Pi OS onto the card. You'll need a Windows, Mackintosh, or Linux PC plus an SD card reader to accomplish this. (You can also do this on a Chrome Atomic number 76 gimmick by following these instructions.)
If starting with a microSD bill with NOOBS preinstalled, go directly to Mistreat 3. You'll install the operating organization after powering on the Raspberry Pi 4.
Insert your microSD card into the Raspberry Operative 4. The slot is on the underside of the board.
Attach to the heat sinks to the Raspberry Pi 4.
Install the Bronx cheer Pi 4 in its case.
- If applicable, remember to touch base the case's lover to the Raspberry Pi 4's general-purpose stimulus/output (GPIO) pins. Usually, the case will accompany instructions connected which GPIO pins to use.
Turn on your reminder.
Plug in cables for display output, USB devices, sound, and, if you prefer a wired connection, ethernet.
Eventually, plug in the power supply. (If yours has an connected/away interchange, don't leave to flip it on.)
- For microSD cards with Hiss Pi Bone already installed, quaternity Raspberry Pi logos leave appear along-screen as the machine begins to boot.
- For microSD card game with NOOBS preinstalled, you'll now commence the installation process for the brimful version* of Raspberry Pi OS.
Complete the initial setup witching's steps: Changing the default on word, connecting to the Wi-Fi network, etc.

*Alternative OS install: You can instead choose the standard version of Raspberry bush Pi OS if you Don't straightaway plan to edit out whatever .docx, .xlsx, or other Agency documents happening the Bir Pi 4 itself. (It makes for a faster OS installation.)

To install LibreOffice later, open a terminal window and update your system and its package repository by entering sudo apt update , then when that's terminated, sudo apt rising slope . Afterwards, enter sudo apt install libreoffice .

Additional required software installing

Streaming media support

Installation time: <1 min*

Unfashionable of the loge, Raspberry Shamus Osmium supports solitary pick out flowing video and audio services—primarily free sites with unaccredited contented. (Think YouTube and Twitch.) Big, fashionable platforms like Netflix, Hulu, Amazon Select Television, and Spotify don't sour.

Widevine error message in Netflix in Raspberry Pi OS

Why? Those services protect their licensed mental object with DRM, and the card that decrypts it isn't available for Hoot Pi OS's default browser. On top of that, ARM-friendly variants of desktop software that supports playback happening those sites (including browsers with that oh-then-necessary Widevine Content Decryption Module well-stacked-in) don't exist.

Luckily, there's a workaround—a Raspberry Pi residential district penis titled ventz discovered they could extract the Chromebook version of the Widevine CDM plug-in, then combine information technology with a user-agent switcher extension in Raspberry Pi OS's Chromium web browser.

You canful find detailed instruction manual and background data about this solution in their blog post, but they've since created an cushy, one-line statement to implement it:

Open a Final windowpane.
Paste in the undermentioned text, then hit Enter: gyre -fsSL https://pi.vpetkov.profits -o ventz-media-pi sh ventz-media-pi
Boot.

Chromium Media Edition workaround for watching or listening to DRM-protected streaming content — Afterwards implementing this workaround, you'll have two choices for a browser.

In the Coating Carte (found through the Taskbar connected your desktop screen), you should now see a new option for Chromium under Cyberspace: "Chromium (Media Variation)." Load this version whenever you bid to stream from Netflix, Hulu, Spotify, or other Widevine-dependent services.

(If you wish to make any adjustments to your browser settings in the future, do so by launching the regular "Chromium" shortcut, not the "Media Edition" one.)

* A note on security:

Using the one-line command fix does require trust in an cyberspace unknown—which you may not regard to give if this PC will be used for sensitive syntactic category business (e.g., banking). If so, you can instead try unmatched of these terzetto alternative options for media streaming:

Buy a second microSD wag, install Raspberry Pi OS, and leave information technology as is outside of regularly installing OS updates. Swap in this card whenever you have to handle with sensitive information.
Buy a separate flowing media device to secure into your monitor operating theater TV, like a Roku Premiere or Fire Idiot box Stick. You can commonly find these for about $25 to $30 on sale.
Rhenium-create ventz's resolution from scribble yourself. Indefinite individual-described "paranoid/inquisitive" Raspberry Pi residential district appendage has already done so with success; those experienced with Linux (or willing to learn on the fly) should Be able to do the indistinguishable.

User feel for

Gross, this little computer is fairly nipping for such budget hardware. You will notice pauses arsenic the system loads a new application or browser pill, and occasionally light screen tearing while streaming video. But once you're bump off and flying, the basics run smoothly.

For more specific details, we've disorganised out the experience in general tasks below.

Tip: Using speakers with the 3.5mm jack? Raspberry Pi OS defaults to HDMI for audio output, so you'll need to switch to Parallel and then reboot to get along sound.

Web browsing

Chromium in Raspberry Pi OS — Raspberry Pi OS's Chromium browser is au fond Chrome, but the open-source version.

Based on similar code to Chrome, Raspberry Pi OS's default on browser is virtually isotropic to Google's version. Chromium supports the same set of plugins and extensions, and has the synoptical layout for settings and bookmarks. In a nod to privacy and performance, IT comes preinstalled with uBlock Origin, an advertizement-block denotation, and H264ify, an extension that forces YouTube to stream potentially less strenuous versions of videos. DuckDuckGo is also the default search locomotive.

Lading webpages often have a second or two of hold up, only otherwise the experience is no different than on other devices. Adobe Flash works American Samoa unsurprising, as do television conference sites like Google Fitting and Zoom. (Raspberry Pi OS mechanically recognized our Logitech C920 webcam; no additional number one wood installation was necessary.)

Cyclosis video/audio

Netflix on a Raspberry Pi — Loading a TV program or movie can take a little longer than on faster devices, but the television playback is smooth.

All cyclosis of video and audio has to be cooked through a web browser—and only works for the big-advert paid services afterward applying the workaround outlined above.

For the most part, video playback is smooth at 1080p. You Crataegus laevigata notice subtle hitches in segments with debauched movement, only they stood out only when watching dance videos, a genre where the barest lack of synchronise between video and audio tracks becomes glaringly apparent. Foreign of occasional light screen tearing, watching movies and TV shows felt equivalent to other devices.

One leading light difference between the Raspberry Pi 4 and other devices is the delay when entrance and exiting fullscreen mode in videos. It takes various seconds before the system will actually make the switch. Playback remains steady finished the passage.

Desktop programs

LibreOffice on Raspberry Pi OS — LibreOffice is surprisingly parky. Hitch, in line, requires a little more longanimity—even off executing commands within the program can induce system cart.

Compared to x86-based Windows, Macintosh, and Linux PCs, a few desktop applications are available for Raspberry Pi OS. The options expand a runty for those familiar with compiling programs, but still not by much. Given that this PC build isn't meant to cover Sir Thomas More than the basic principle, you can install GIMP (an image editor) on a full version of Raspberry Pi OS, or some LibreOffice and GIMP on a standard edition, and leave it at that. Your bases will be moon-splashed.

Within those desktop apps, you will observance pauses as the scheme opens the curriculum OR a file, and sometimes even when executing a command. It's unquestionably slower than happening a pricier political machine, but for a budget machine that costs $100 in complete, we find it an unexceptionable live. Note that we did not test using very large spreadsheet files—our pretend is that those will drag on this car.

Final thoughts

At $100, this build's but downside is that you deficiency room to grow. For extraordinary folks, IT English hawthorn besides not represent as appealing as a Chromebook with a built-in screen out and webcam, or an older, used x86-settled system. Just as we always say, the beauty of the PC is the freedom of choice—and this project can be ideal Eastern Samoa the first electronic computer for a young tiddler, a comparative who dislikes the small screens and higher prices of tablets and Chromebooks, or a secondary computer for guests to consumption.
