For many gamers of a certain age, the first experience they had with a first-person shooter was the iconic game Doom from iD Software. Graphics and game developer Sylvian Lefebvrehas designed a device called the "Doom-Chip" with the sole purpose of running the first level of Doom. Lefebvre said in a tweet announcing his creation that it would run "E1M1 till the end of times" or until it runs out of power. Lefebvre was able to get the game running on an Altera Cyclone FPGA board. The feat means that the first level of the classic shooter is embedded directly in hardware rather than being software as gamers remember it. The developer said in the tweet that the algorithm is burned into wires, LUTs,...

Rather than go stir crazy while social distancing, some people are busying themselves with fun and unique projects involving the Raspberry Pi. Eben Kouao is one of those folks. He took a Raspberry Pi 4 Model B (2GB) and built himself a smart mirror, which is exactly what it sounds like—a mirror with smart capabilities and touch support. It also features facial recognition capabilities, giving his Smart Mirror AI (SMAI) project some added depth and usability. "With SMAI, you can now keep track of your daily tasks, control your home appliances through its touch interface. With its facial recognition, you can now load up your personalized information—ranging from your daily commute to...

We've seen several cool projects during the coronavirus pandemic that people have designed using the Raspberry Pi platform. Over on reddit, another very cool project has turned up from someone going by balmy-summer, and the project is called the Pi MixMakr. The project has five bottles of liquor on top along with five dispensers inside the cabinet. The drink glass is set on a sliding platform that moves under the bottles to mix a cocktail and inject cola or other flavorings as desired. The whole point of the machine is to mix a drink without the drinker actually having to do it themselves. The parts list for the project includes: Raspberry Pi 3B FSR406 (FSR sensor, checks glass is on platform)...

Fully-assembled MiSTer FPGA DIY console It seems like it wasn't too long ago that we crowned the Raspberry Pi 4 as one of the best retro game consoles around. Indeed, the Raspberry Pi foundation's latest single-board computer still a low-cost DIY powerhouse. However, retro gamers are picky about one thing that haunts many software emulation solutions that run on the likes of the Pi 4 or an NVIDIA SHIELD Android TV -- and that's lag. Thanks to a talented group of developers and some off-the-shelf parts, the MiSTer project aims for a lag-free, higher quality, more accurate retro gaming experience. Built on the Terasic DE10-nano (an Intel-based System-on-Chip (SoC) FPGA board), the MiSTer...

Business cards are a staple in the business world and can help make a good impression. What kind of impression would you make if your business card not only shared your contact information, but also ran Linux? One embedded systems engineer did just that. George Hilliard created his own business card that can run Linux and shared the process on his website. According to Hilliard, his idea for the business card came to him when he thought, “These processors are nearly cheap enough to give away.” He noted that he had seen electronic business cards before, but their functions tended to be rather limited. He believes that his own Linux business card could be a great idea for larger business,...

There's no shortage of options in the DIY micro-PC market, one that Raspberry Pi arguably spearheaded over five-years-ago with the release of its first unit. Since that time, a lot of competition has risen to the surface, including none other than Taiwan's GIGABYTE, a company that knows a thing or two about developing motherboards worth using. The GA-SBCAP3450 is an iterative design that builds on the initial release last year. Notably, the biggest upgrade includes the boost to a quad-core processor, a rather gargantuan leap from a dual-core. That chip, Intel's Celeron N3450, can boost up to 2.2GHz, so it has a fair amount of oomph for such a small form-factored PC. While this 14.6cm x 10.2cm...

Intel has always been an interesting company to watch, but lately, we've been looking at how it's adjusting focus to better handle the current competitive landscape. On the CPU side, the fact that AMD is more competitive than ever has been well-documented, both on the desktop side and in the enterprise. Intel has already reduced its focus in some key places, such as wearables. In one example of readjusted focus, the company is now targeting augmented reality as the next big thing it can play a part in. But we're not through with the deaths yet, as today we learn of yet another in the Intel product family: Arduino 101. This DIY tinker board was first revealed a couple of years ago, and with a...

The Nintendo Switch is selling like hotcakes, but that does not mean that the console is without its fair share of imperfections. Some have complained that the Switch’s dock is a little too big and cheaply made. Nintendo fan Alexander Blake’s solution was to turn his old Game Boy Advance SP into a custom Switch dock. Blake remarked, “In the process of tinkering with a second Nintendo Switch Dock, I realized the circuit board was pretty much the exact same size as a Gameboy Advance SP. And then I remembered one of my old SPs doesn’t work anymore. So I got to work.” He replaced the inner workings of the Game Boy with the guts from the Switch dock. Blake then used an X-Acto knife to carve a hole...

In many regards, the Raspberry Pi family of computers is quite modest, which is of course by design. For a relatively small price, you can pick up a fully-functional RPi single board computer that can be used for many purposes, whether it is for learning, creating homemade bots, or cobbling together your own purpose-built media player or server solution. Given RPi's flexibility, it should come as no surprise that the open source Linux-power min PC has proven to be such a popular computing platform for scores of consumers, businesses and educational institutions. Just how popular? Well, while RPis themselves might be "modest", their sales figures are anything but. In fact, the total number of...

Hot on the heels of our coverage of an in-depth guide showing you how to make your own "NES Classic Edition" with a Raspberry Pi, ASUS strikes with a DIY kit that it says is about twice as fast as the RPi 3. The DIY retro gaming arena could be heating up with more powerful options! The Tinker Board, as ASUS calls it, sports a Rockchip RK3288 SoC clocked at 1.2GHz. According to ASUS, and its GeekBench test, this chip is almost 2x faster than the RPi 3's Broadcom BCM2837, which is also clocked at 1.2GHz. Both chips are quad-core, but the Rockchip could help significantly with more processor-intensive tasks. ASUS has other one-ups to talk about, too. Versus the RPi 3, the Tinker Board...

Retro gaming made a major resurgence this past holiday season, with the release of Nintendo’s ultra-hyped NES Classic, a scaled down clone of the original Nintendo Entertainment System. Out of the box, the NES Classic has thirty preloaded game titles, though some recent hacks exposed a method for uploading more if you're willing to mess with it. That's all well and good, but if you weren’t able to get your hands on one this past holiday season -- like the majority of people -- getting your retro-gaming fix isn't happening any time soon, unless you fork out an unreasonable sum, paying hundreds to scalpers, for a product that retails for $60.But, why not roll your own? The Elusive NES Classic...

The Raspberry Pi foundation has found great success with the latest iteration of its mainline product, the RPi 3. Now, the time has come to see that RPi 3 converted to become CM3, or Compute Module 3. Whereas the mainline Raspberry Pi can be easily tinkered with by anyone, Compute Modules are even greater DIY devices, most appropriate for vendors to use in their own products. One such example is NEC, which is deploying a CM into an upcoming display. Compute Module 3 shares the same basic specs as the RPi 3, which is to say it includes a Broadcom BCM2835 SoC clocked at 1.2GHz, 1GB of memory, and 4GB of on-module eMMC flash. The company is also releasing a "Lite" version (CM3L) that moves the SD...

When services are provided for free, it's important to evaluate whether or not there's a major caveat that comes along with it. According to an investigation by CBS News, the free "PC Health" checkup provided by Office Depot carries a big one: you could be encouraged to shell out money to fix a nonexistent problem. If this sounds like a shady mechanic or cars salesman, it's essentially the same thing. Office Depot is accused of telling customers that there are serious issues on their PCs, such as installed malware, even when that's not the case, and can charge them upwards of $180 for the privilege of "removing" it. To test the ploy, CBS purchased a handful of computers and brought them into...

The Amazon Echo has been a pretty hot gadget to have around the home. At its core, the Echo is a smart speaker system which can respond to voice commands care of Amazon's digital personal assistant named Alexa. Alexa can queue up your favorite playlist, remind you about your meetings for the day, re-order toilet paper, or even help set some mood lighting with the right integration. For all the fun and convenience the Echo can offer, though, it doesn't come cheap with a current price point of $179.99.Fortunately, Amazon has provided a solution to this cost problem, provided you are willing to get your hands dirty. Amazon released instructions on GitHub this week on how to setup...

It's beginning to look like Raspberry Pi's developers are keen on releasing newer models a lot quicker than before. The second generation unit was released just last February, and already we're being treated to a tease of the third iteration. Well, by "tease", we mean that the FCC has a public filing now of all of the important bits of info - including photos. At first glance the RPi 3 looks similar to the Raspberry Pi 2. With top-down images side-by-side, it took us some serious effort to spot the differences, and the differences we did see turned out to be some modification to the traces and filter cap arrangements on the board, not the ports, headers and slots. The only thing the...

Typically when you hear of someone wearing an electronic device around their ankle, your first thought may they made a bad decision that led to house arrest. You may not have considered many other scenarios, though Netflix did, and so the concept for Netflix Socks was born. Will it spread? That may be up to you and your sleep habits. We've all been there, fighting off sleep like a grumpy child, only we're doing it because we're trying to power through yet another episode of Orange is the New Black or catching up on Breaking Bad (both are awesome shows, by the way). Eventually we succumb to our inevitable fate, drifting off into la-la land while Netflix continues playing in the background. What...

Sometimes, it's enlightening to see what people are willing to do in order to bring the rest of us joy. Take stop motion animation, for example. It can take tens or hundreds of tedious hours to produce something that's worth watching. When watching a video like that, though, it's easy to have an idea of what to expect. Other times, you might have no idea what's coming, such as with a video posted at the end of October by YouTube user Mickey W. To give people a chance at winning one of its 34UC87C ultra-wide monitors, LG hosted a contest to get people to build computers out of cardboard. You no doubt already have some images springing to mind. Mickey W took things to the next level, though. His...

It might have taken nearly an entire year to arrive, but the official touch display for the Raspberry Pi is here. Fortunately, the long wait isn't being met with an overpriced product - that'd be rather atypical of the Raspbery Pi foundation. Instead, you'll be able to get a very capable 7-inch touch screen for about $60 USD. With a resolution of 800x480, this is far from being a "high-resolution" panel, but the feature set more than makes up for that. It takes advantage of the RPi's DSI connector, which allows users to continue using the HDMI port for other purposes - and it is possible to use both the touchscreen and external display at the same time. Another cool perk: the chassis can be had...

It might be hard to believe, but the Raspberry Pi finally has an official case, and it's one that's had quite the journey to come to fruition. While a case might seem like a simple endeavor, RPi's Gordon Hollingworth notes that the beginnings of this one began two-and-a-half years ago. It's a good thing that the end result looks great: One of the biggest design goals of this case was to make it attractive, but affordable - two aspects that are sometimes rare to be see together. After all, no one really wants to use an "ugly" case, but if you're going the RPi route to begin with, you probably don't want to pay as much for the case as you did the hardware. In this "case", you won't have to, as...

As part of its 'Make it Digital' campaign, the BBC will be giving a staggering 1 million mini DIY PCs, called 'Micro Bit', to year 7 (sixth grade) students across the UK later this year. The goal is to help students become familiar with product development, which will be aided by the launch of coding-based programs at the same time. These Micro Bit PCs are similar in context to the Raspberry Pi, although they are much simpler in design. That being the case, the BBC is not considering it a competitor to existing products, but instead something that might spur kids to want to make the jump to more complex DIY boards and likewise, projects. When the coding programs go live, students will be able...
