In 2015, Valve released Steam Link, a small computer that allowed you to stream video games over your network to your TV, tablet, or phone. In 2018, Valve announced that they’d be discontinuing the hardware.

Later that year, they officially released Steam Link for the Raspberry Pi, allowing you to continue streaming your favorite video games across your network.

You don’t need to spend hundreds on eBay to mess around with vintage computers. Our guide on Raspberry Pi retro computer emulation features the most popular vintage computers that can be emulated on the Pi; check it out (and if we’re missing your favorite, let us know in the comments section).

Many systems can be emulated directly in RetroPie; other systems require their own image to be loaded in order to run. Either way, it only takes a few clicks and keystrokes and you’ll be in monochrome heaven. While you’re there, you can even play some of your favorite retro computer games. 😉

Pi-Hole is a free network-wide ad blocking library.

What does this mean? While traditional ad blockers block ads after they’ve already passed through your network, Pi-Hole essentially allows your Pi to act as a DNS server, blocking ad network scripts before they use your precious network bandwidth.

Many users report seeing as much as a 25% reduction in network traffic — in other words, 25% of their former traffic was ad-related. Check out our Pi-Hole setup guide to get started!

Have you seen those Raspberry Pi magic mirrors making the rounds? A clever two-way mirror setup overlaid over an old computer monitor creates a holographic effect; a futuristic display showing the day’s weather, traffic, calendar, and more!

The magic mirror is then mounted on the wall or set on a table. The most popular platform for building the smart mirror “dashboard” is MichMich’s MagicMirror^2.

You can also install the Magic Mirror dashboard and display it on your normal computer monitor without the mirror effect.

Why not talk to your mirror and have it talk back? Google Assistant can be installed on any Raspberry Pi using the Google AIY Voice Kit; so a Google Home-enabled magic mirror is an obvious choice. 🙂

Clap on! Clap off! Pi Clapper! 👏👏

As annoying as that commercial was, you have to admit The Clapper was pretty cool. Now you can control your Pi (and other things) with your very own Raspberry Pi clapper.

Shut down your Pi, send a Tweet, turn off your lights, activate a servo motor, or anything else you can come up with — all with a clap or two.

A Raspberry Pi is mounted inside the housing. Holes are then drilled through the housing and plexiglass to securely mount the buttons and joystick. Finally, the buttons are connected directly to the Pi via USB.

You can use the Retrobox as a normal USB device as well — on your computer or another Pi (this means you can even build a second one for a second player). This is definitely a cool project and one of the most fun ones we’ve ever created.

When thinking about home automation, controlling your garage door is a pretty obvious first. This guide will teach you how to create your own Raspberry Pi garage door opener so that you can open and close your garage door remotely using your phone!

This is indeed a neat approach — one of your original garage door remotes is connected via a relay directly to the Pi. A small webpage running on the Pi can be accessed via your phone or computer.

When you tap the button on the webpage, the Pi triggers a relay connected to the garage door opener and your garage door opens or closes. A sensor monitors your garage door’s state (open, closed, or partially open) so it knows which command to send.

If you have an outdoor project that you’d like to run continuously (or just think alternative energy sources are really freaking cool), then you might want to power your Pi using solar power.

In a nutshell, a rechargeable battery pack and power management board are connected to your Pi; then, a solar panel is connected to the power management board, allowing your Pi to operate in rain or shine. You can also connect the solar panel directly to the Pi but depending on the size of the solar panel and the cloud cover where you live, this might lead to continuous, unexpected shutdowns.

Either way, this is a fun project that will teach you a ton about electricity, solar panels, batteries, and powering DC electronics portably.

The Gamepad Zero is a Raspberry Pi Zero inside an original NES controller. The original controller is soldered directly to the Pi’s GPIO pins, meaning the original NES controller’s printed circuit board is used as the controller. Additional controllers can also be connected for multiplayer action!

You’ll need access to a 3D printer for this project! Don’t have one? Check out the guide for other options to get your model printed.

Similar to the Gamepad Zero, but with more buttons! The Super Gamepad Zero uses a Super Nintendo controller in place of the original NES one, giving you access to better ergonomics and more buttons, allowing you to emulate more games than the original Gamepad Zero.

Once again, you’ll need access to a 3D printer for this project. If you don’t have one, check out the guide for other options to get your model printed.

If you run into trouble, post in the comments section for the particular guide and we’ll help you out!

Access the Raspberry Pi terminal using SSH or by connecting a keyboard, mouse, and monitor to your Pi.

Use the following command to access the full list of configured wireless networks:

/etc/wpa_supplicant/wpa_supplicant.conf 

You’ll be prompted to enter your Raspberry Pi password—the default Raspberry Pi password is raspberrypi. If you haven’t already, I highly recommend you change your Raspberry Pi’s password after logging in by running the following command:

passwd 

To forget a specific Pi wireless network, delete the corresponding network block, surrounded by opening and closing {} curly braces. For example, deleting the following will “forget” the serenity network:

network={ ssid="serenity" psk="shepherdBookHasScaryHair$1" key_mgmt=WPA-PSK } 

If you want to forget a network but keep the configuration in place for later, you can uncomment the block instead by adding a # symbol to the beginning of each line. For example, uncommenting the following will “forget” the serenity network while keeping the details in the file for future use:

#network={ # ssid="serenity" # psk="shepherdBookHasScaryHair$1" # key_mgmt=WPA-PSK #} 

When you’re done, save and exit by pressing CTRL-X, typing Y, and pressing enter.

A recommendation before deleting

Of course, if you’re connected to your Pi via the network you want to remove, you’ll be disconnected from the Pi as soon as your Pi forgets the network.

Therefore, I recommend adding a new network before deleting the other network—this makes it slightly easier to add your “new” network. If you need to, finding which network your Pi is connected to is easy.

Connecting to a new network is as simple as generating a new wpa_supplicant.conf file or by running the raspi-config utility.
