What Is Raspberry Pi and How Can I Use It for My Home Internet?
A Raspberry Pi computer can do a little of everything, including keeping you occupied if you need a new project (or distraction). This teeny-tiny computer not only clocks in at a low price, but could potentially help you trim costs by becoming a DIY router. Saving money is appealing: A recent CNET survey showed that internet costs spiked for 63% of US adults last year.
When our budgets are tight, having a device that can cover the gamut is appealing, from hosting your home internet to providing a platform for your next gaming experience. What was once a simple tool for teaching students about computers has become a fun tech experience for computer lovers everywhere. Not familiar with a Raspberry Pi computer? Let's take a closer look at these pocket-sized machines.
What is a Raspberry Pi computer?
Raspberry Pi is a tiny, inexpensive computer about the size of a credit card. It was initially developed in the UK to teach school kids about computer science. As the single-board computer has become more popular over the years, people have used it for various projects. It has evolved into newer, better versions with Bluetooth and Wi-Fi capabilities, and its price has kept falling.
Raspberry Pi computers don't have hard drives — they don't have much at all — but this is why they're great starting points for people who want a project. They have ports so you can plug in a monitor and keyboard, as well as a microSD card, and once you've installed an operating system, you can use the Raspberry Pi as a full-fledged desktop computer.
The Raspberry Pi 5 is the most recent iteration, with a 16GB model that launched in January. It has a 2.4GHz quad-core 64-bit ARM Cortex-A76 CPU and a VideoCore VII GPU, a significant upgrade from the Pi 4. It's also available in 2GB, 4GB and 8GB, with prices from $50 to $120. The Raspberry Pi Zero is the most minimal model, retailing for only a few dollars. While it can still run many of the same functions as the other Pis, it doesn't run nearly as smoothly (or as quickly) as the ones with more RAM.

What is Raspberry Pi mostly used for?
Raspberry Pi isn't most people's first choice for a desktop computer. You're most likely getting this computer if you want to tinker with it or have another project in mind. However, Raspberry Pi can function as your primary computer. Popular ways people use their Raspberry Pi include as gaming consoles, running their smart devices and as internet routers. In terms of gaming, one option is to configure your Pi for throwback games with RetroPie, an open-source software that works with any Raspberry Pi.
You can also link a Raspberry Pi computer with your smart devices to conveniently control your lighting, TVs and more. You can also use it as a router for home internet (more on that later). The uses and capabilities of this tiny computer are endless, and a quick Google search will turn up even more ideas you can do with it.
Why would I use a Raspberry Pi computer?
Many people use Raspberry Pi computers because they enjoy the thrill of building a computer and like the uniqueness of what Raspberry Pi provides. Truthfully, there is no specific reason to use a Raspberry Pi computer versus any other computer or machine. Various other devices exist in much the same way. It is often about the novelty that this one provides.
If you surf through the Raspberry Pi subreddit or the Raspberry Pi Forums — both of which are packed full of Raspberry Pi folks, from novices to pros — you'll find thread after thread of people discussing their Raspberry Pi projects, big and small. Within the discussions, you'll see notes on how they're using the pocket-sized computer, why they're doing it, advice and more.
All of this is to say that you'll often use a Raspberry Pi computer because it's fun and a challenge. It was originally created as a teaching tool, and it continues to be a great learning device for anyone who wants to understand more about computers without breaking the bank. Plus, you can do some cool things with them.
As you figure out all the uses of your Raspberry Pi, you may want to reward yourself with some raspberry treats.

Is it safe to use a Raspberry Pi computer?
Regarding security issues, a Raspberry Pi computer is relatively safe, though it has risks. Then again, so does any desktop or laptop. Where you run into some trouble with a Raspberry Pi is the Linux operating system it runs on, because it uses a microSD card. That leaves your computer a bit vulnerable (though the open-source Linux is quite solid and many prefer it to any other OS) because someone could simply walk away with the microSD card, as a DZone report points out.
You can ensure that your Raspberry Pi is more secure internally and physically by encrypting the device and making it more difficult to steal your information. It's highly recommended that you do this (much like you'd do with any computer to prevent hacking or data breach) but, in general, Raspberry Pi is no more vulnerable than other computers.
Can Raspberry Pi help my home internet?
Your Raspberry Pi can be used as an internet router on your home network, though admittedly, the Pi is better equipped to handle smaller networks. Some Raspberry Pi users have found more success as a travel router because it functions better as a Wi-Fi tool or hotspot in small use cases.
But don't worry, you can still use it at home for your internet. There are a few handy guides to set up your Pi for internet access at home. These will essentially walk you through the process of ensuring your Pi is up to date, has the right software and can bridge between networks. This guide on Medium turns your Raspberry Pi into a Wi-Fi router, and this Raspberry Pi YouTube video shows how to add Ethernet to your Pi. Finally, a Raspberry Pi 5 can also be turned into a Wi-Fi extender using this handy guide.

The Jetsons Promised Us Jet-Propelled Cars of the Future. Here's Why That'll Never Happened
Automakers are on a massive quest to find alternative fuel sources. Some believe batteries are the future, while other, more skeptical minds are exploring hydrogen , synthetics , and other alternatives in hopes of keeping the combustion engine alive . However, they might have overlooked a far more exciting alternative—jet propulsion. A new Garage 54 video attempts to find out if you can propel a car entirely by high-pressure steam, and it turns out that yes, you can. However, it doesn't appear to be an efficient, effective, or safe alternative to gasoline, electric vehicles, or walking. In fact, it's quite the opposite. The crew outfitted an old Lada with external braces to hold the high-pressure tank that they filled with water. They then built a fire around the tank to create the necessary steam inside, but it took them several attempts to get it to work right. However, the system finally worked, propelling the little Lada across the field before running out of steam. The pressure was strong enough to deform the vehicle's structure, revealing the tremendous power water and fire can create in specific conditions, but it's a short-lived source of propulsion. It took the Garage 54 team several hours to get it working, and in a world where our cars must be reliable, waiting around to create enough steam to make it all the way to work would take too much time. Sadly, jet-powered cars are not the future, no matter what the Jetsons promised. The massive jet of steam out the back isn't practical or safe, even if it looks cool.

Elon Musk biographer says major Tesla merger could be imminent: 'I think it's going to happen'
Could Tesla eventually merge with another of Elon Musk's companies, xAI? A prominent insider thinks such a move is increasingly likely. Walter Isaacson, the prominent Musk biographer who has received unprecedented access to Tesla's CEO, recently said he expects the two companies to eventually merge, Not a Tesla App reported. During a CNBC interview, Isaacson said combining Tesla and xAI would ultimately better serve each company's mission. "I think it's going to happen," Isaacson said, per "Because Musk, even in my book when he's starting xAI, [was] talking about [how] these chatbots are fine, but what you need is real-world AI. You need to be able to not only take all the texts and tweets that have ever been written, but all the videos from Teslas and all the Optimus robot [is] seeing and hearing." Tesla was a pioneer in electric vehicles and still has the top-selling vehicles in the space — although its sales numbers have dipped this year. But Musk has repeatedly said that the future of the company is tied in more than just cars, including "vast numbers of autonomous humanoid robots." That makes xAI seem like a natural partner for Tesla. It is behind the artificial intelligence assistant Grok, which will reportedly power Tesla's upcoming smart assistant. Musk has also said he expects Grok to be incorporated into Tesla's Optimus humanoid robots, with hopes of sending them to Mars in the near future. In May, Musk said in a CNBC interview, per Business Insider, that "there are no plans" to merge the companies, but that "it's not out of the question." Tesla's sales may have had a bumpy start to the year, but there's no denying the role it has played in bringing millions of cleaner cars onto roads around the world. Studies have shown that driving an EV can reduce carbon pollution by two-thirds compared to gas-powered cars. EVs can be even greener when paired with a renewable energy source for charging, such as solar. In addition, if you have solar panels, that energy is considerably cheaper than relying on the grid or public charging stations. EnergySage allows homeowners to save thousands on solar-panel installation costs by comparing quotes from local, vetted installers. And if the upfront costs of solar are too daunting, Palmetto's LightReach program allows people to lease solar panels, providing locked-in, low energy rates, and a lower carbon footprint, with no down payment. Do you think electric vehicles are efficient enough to replace gas cars? Totally Definitely not They're almost there They need a lot more work Click your choice to see results and speak your mind.

What Investors Should Know As Meta Gets (Back) Into Crypto
Meta (formerly Facebook) is getting back into crypto Markets and investment trends tend to move in cycles, and the cryptoasset sector is no exception to this rule of the marketplace. As TradFi institutions continue to deploy blockchain affiliated projects, including the launch of a stablecoin by SocGen running on the Ethereum blockchain, the adoption and acceleration of cryptoassets continues virtually unabated. Even as the sentiment toward crypto improves, prices of bitcoin and other cryptocurrencies increase, and the policy landscape pivots toward a pro-growth outlook there remain significant obstacles to mainstream utilization. For example, the tax treatment of crypto is an inhibitor to retail utilization of crypto as a method of payment, and the lack of insurance available for crypto and crypto-adjacent products can make it difficult for institutions to allocate substantial funds to cryptoassets. Against this landscape, exemplified both the increasing adoption and understanding of cryptoassets and applications with the continued limitations to institutional usage, one company stands apart for several reasons. Meta (formerly Facebook) recently has been questioned by Senators Warren and Blumenthal related to its support for the GENIUS Act, and specifically whether or not the firm would block a prohibition on Big Tech firms from owning stablecoin issuers. The specifics of the questioning by the senators will most assuredly change over time, but the letter that has been made publicly available detail that the senators desire specifics as to what the stablecoin plans for Meta are. Let's take a look at why this letter and these questions are important, not only for Meta, but for the cryptoasset marketplace at large. Meta, then operating as Facebook, already attempted to launch of a native stablecoin in 2019 via the Libra project which was subsequently rebranded as Diem. This previous effort occurred during an entirely different economic and policy landscape, and occurred as the organization was still contending with intense scrutiny following the 2016 U.S. Presidential election. Issues that were raised at the time dealt with the potential of a stablecoin issued by Facebook serving to weaken competition, compromise user privacy, and lead to continued fractionalization of which entity or organization sets policy for U.S. monetary and fiscal policy. While the cryptoasset landscape and policy outlook for crypto projects has definitively shifted to a more permissive stance the very same issues that were raised during 2019 loom large as Meta returns to the stablecoin marketplace. Specifically, the letter from the Senators cited the track record of privacy violations, scams, and fake news that continue to occur on the platform as risks that a native stablecoin could amplify. Even as stablecoins increasingly become more mainstream, and are approaching a market capitalization nearing $300 billion, Meta might find many of the same issues that stymied earlier efforts being dragged back to the surface. Since Meta is one of the few returning players to the stablecoin space this provides an opportunity for crypto native stablecoins such as Circle, which continues to ride high following its IPO in June. As Meta edges closer to launching its own stablecoin, the spotlight on Big Tech's role in digital money is about to get a lot brighter, especially as these same tech firms continue to invest billions in AI initiatives. For crypto-native firms like Circle, that's not a threat - it's an opportunity. Meta's sheer size and complicated history with data privacy all but guarantee it will draw intense regulatory scrutiny. And that scrutiny will set a new bar for how stablecoins are viewed and governed both in the U.S. and abroad. That's where Circle can shine. Unlike tech giants pivoting into payments, Circle was built in crypto — with regulatory engagement and transparency as core pillars. While Meta faces inevitable trust questions and regulatory hurdles, Circle can double down on its position as the safer, more compliant alternative. In the coming months, expect firms like Circle to lean into this advantage, especially as institutional partners and consumers alike grow more cautious about Big Tech controlling their money. Notably, the ongoing partnership between Circle and Coinbase – two of the largest crypto native firms that are publicly traded in the U.S. – can also serve to assuage concerns of policymakers. Regardless of this specific stablecoin project plays out the following reality is becoming increasingly clear, and some would say urgent, for the crypto marketplace. With tens of billions flowing into the sector, TradFi firms deploying blockchain based solutions and native stablecoins, and policymakers actively debating the GENIUS Act, the crypto audit and attestation narrative continues to seem stuck. While the AICPA continues to issue guidance and updates related to digital asset attestation, controls, and valuation, the authoritative standard setters remain behind the proverbial curve. As stablecoins become more important and integrated with payment, treasury, and lending systems the urgency for definitive and standardized auditing best practices will continue to elevate in importance.
