Review of Raspberry Pi's 7-inch touchscreen display

The Raspberry Pi Foundation recently introduced a low-cost  7-inch touchscreen display for the Pi (compatible with all models expect the Pi 1). It's a great display for retro-games and other projects. Here's a quick review from ETA Prime. Read the rest

Making a flying saucer clock (with data storage) controlled by a Raspberry Pi

I love this strange and wonderful project on Hackaday.io. It is digital clock which uses a ring of 60 NeoPixels in a 3D printed flying saucer and 12 lights on the inner ring to indicate the hours. It also does backups. And light shows. All it needs is a cow being sucked up into it.

At the end of November 2019 my trusty old iomega StorCenter NAS (Network Attached Storage) started behaving eratically and would keep disappearing from the network and locking up every few hours. I immediately made sure I had several copies of the data and started the search for a replacement. But it dawned on me that whatever I would buy would ultimately go the same way: unsupported and unfixable.

So, with the new Raspberry Pi 4 having USB3 ports and a long running desire to make a circular neopixel clock at some point, it dawned on me that there are two devices that run 24 hours a day: my NAS and my trusty old Tix clock that I bought several years ago.

Why settle for another boring NAS when I can make the ultimate NAS come Clock combination? So began the flying saucer clock project...

So, how does it tell time?

The inner ring of the saucer contains 12 LEDs behind diffusers made from a ring of transparent PLA with black PLA colour separators, which are lit according to the current hours. The minutes and seconds are shown on the outer 60 LED ring. This also displays the hour as a series of 5 LEDs lit blue and also hour markers shown at spacing of every 5.

Video tutorial on how to play retro video games with a Raspberry Pi

In this video from Pi My Life Up you'll learn how to install and use software called RetroPie on a Raspberry Pi. RetroPie lets you emulate a bunch of different game platforms, like Atari 2600, Sega Genesis, Game Boy, and so on.

By the way, I co-wrote a book with Ryan Bates called Raspberry Pi Retro Gaming: Build Consoles and Arcade Cabinets to Play Your Favorite Classic Games, which has instructions for building a tabletop arcade machine. Read the rest

Low price on a Raspberry Pi 3 B+

This is the lowest price I've seen for a Raspberry Pi 3 B+ single board computer. It has a 1.4GHz 64-bit quad-core processor, WiFi, Bluetooth, and Ethernet. These Pis are great for playing retro video games (emulators for almost every game platform from the 80s and 90s you can think of are available). This Amazon deal is 16% claimed so far. Once it's fully claimed the price will go back up. Read the rest

Raspberry Pi 4

The fourth incarnation of the wonderful Raspberry Pi is upon us. A faster quard-core CPU, up to 4GB of RAM, gigabit ethernet and dual HDMI outputs are the upgrades; there's USB-C too, but just for power. The CPU boost is a big deal, say early users, but dual-4k displays and 4x the RAM bring it squarely into the realm of everyday desktop computing. Still $35; the 4GB model is $55.

Life goals: stick a Raspberry Pi in an old TV, stereo or clock

Christian Cawley listicled 10 old devices upcycled to house a Raspberry Pi (including the Tomy toy dashboard OutRun previously at BB).

Embedded above is a Pi, with a wee LCD monitor, embedded in a 1975 mini TV by Martin Mander. Perfection!

This is a Hitachi I-89-311 portable TV that I've converted into a retro wall-mounted information station! It displays useful content in a series of full-screen Chrome tabs, and turning the TV's tuning dial switches between the pages. The volume button controls scrolling, the on-off button refreshes the page, and the TV has a PIR motion sensor so it turns off when you walk away.

I made this cool desktop video game arcade machine with the help of a Glowforge laser cutter

This post was sponsored by Glowforge. Click here to get $100 off a Glowforge Basic, $250 off a Glowforge Plus, or $500 off a Glowforge Pro.

This is the second of two videos on how to make a Raspberry Pi based tabletop retro-video game arcade machine. (Here's the first.)

Once we bought the components and made sure everything worked it was time to design and cut the cabinet.

Any graphics program will work with the Glowforge. You can even use a hand-drawn image because the Glowforge has a built-in camera that scans your drawings and converts them to cutting, scoring, and engraving lines.

Cutting

Once we had a design we liked, we uploaded it to the Glowforge app. It’s as easy as dragging and dropping the image file onto the page, then placing the design on the photo of the material You can move the images around the material in order to fit multiple components onto the same piece of stock.

The first prototype we made had sharp corners, and they poked into our palms when we used the buttons and joystick. So for our second design, we used a living hinge, which is a cool way to bend wood. With these kinds of hinges, you can make beautiful and functional things.

Customization

The Glowforge not only cuts material, it also engraves designs - even photos - in high resolution. We engraved one of our favorite characters  -- Q*Bert, the famous cussing cube-hopper. And my daughter and I took a cue from the original Macintosh team and engraved our names on the inside of the cabinet. Read the rest

Play thousands of retrogames with this DIY table arcade game player

[This post is sponsored by Glowforge. To get $100 off a Glowforge Basic, $250 off a Glowforge Plus, or $500 off a Glowforge Pro use the link glowforge.com/boingboing.]

My 15-year-old daughter and I love retro video games. We often go a retro video game arcade in Pasadena, California, and we also play a lot of computer games from the 1980s and 1990s. We thought it would be fun to build a dedicated machine at home that we could use to play these retro games.

After a bit of online searching, we found out it’s easy to use a Raspberry Pi, which is a $35 single board computer the size of a credit card, along with a free Linux based operating system called RetroPie that has emulators for every arcade and console imaginable. We could use a Raspberry Pi and RetroPie to play every arcade game we want. And with our Glowforge laser cutter, we could easily make an arcade cabinet for ourselves as well quickly make them for friends and family.

In this 2-part video series, which was underwritten by our friends at Glowforge, I’m going to show you how we did it.

Parts and Materials

First, we bought all the parts and materials we needed to make the cabinet. We got a Raspberry Pi Model 3 B+, a 32GB MicroSD card, a power supply, a 10-inch HDMI monitor, a set of arcade buttons and a joystick, a pair of speakers, some cables and a box of various machine screws and nuts and standoffs.

Karaoke casemod: it's surprisingly easy to hook up a karaoke machine's CRT to a Raspberry Pi

Brett writes, "As a critique of the IoT buzz, I hacked a portable karaoke machine, stuffed a Raspberry Pi in it, connected it to the internet, and installed Docker on it." (tl;dr: he needed a portable CRT for an installation, found one embedded in a thrift-store karaoke machine, and got it wired up to the Raspi on the first try and discovered it made a perfect and delightful casemod).

Mice can get into amazingly tight spaces

I spent the last few days fighting off a mouse infestation in our RV. So far I've trapped and tossed six of the furry little bastards out on their asses. As I began the search for where they were getting into our rig, yesterday, I got to wondering how much space they can actually squeeze through.

According to this video, I'm doomed. Read the rest

Linux for Makers, by Aaron Newcomb

I've had very little experience with Linux but now that I'm using Raspberry Pis (a cheap single board computer that runs Linux) I need to know how to use Linux. Online how-tos are good, but Linux for Makers, by Aaron Newcomb, is better. In fact, this book is pure gold. It assumes zero prior knowledge of Linux. Everything is clearly explained. I learned how to install Raspbian Linux on an SD Card (Raspberry Pis use SD cards as their hard drive), log the output of a script, schedule jobs with cron, use lots of different commands, write scripts, use PI with IFTTT, and lots more.
