The Raspberry Pi Hub: 45+ Tips, Tricks, Tutorials, and Guides

https://ift.tt/2wBc98P

We have all the tips, tricks, tutorials, and guides you’ll need to become a full-fledged master of the Raspberry Pi. Newbies and veterans, welcome!

The Raspberry Pi is a single-board computer, a fancy term for any tiny-yet-fully-operational computer that’s built on a single circuit board. It can do everything that a normal computer can—such as run software, connect to the internet, control USB devices, and more—although the computing power and speed of a Raspberry Pi falls short of modern desktop CPUs. Its main selling point? Small size and cheap price!

Still not sure what a Raspberry Pi is, exactly? Want to know why it’s called Raspberry Pi? Who invented the Raspberry Pi and when was it launched? Why are there different Raspberry Pi models and what are the differences? Learn all of that and more in our newbie’s introduction to the Raspberry Pi.

Camera Records Critters Crossing a Log in the Woods for a Year

https://ift.tt/2xkhm52

On each day of our lives, we have time to spend. The way we choose to spend that time varies, and the value of our minutes depends on how each one is spent. I contend that spending five of your minutes watching this video is a good idea.

YouTube channel “Bush’s Pennsylvania Wildlife Camera” placed a game camera on at a log crossing a small creek for an entire year to capture all the wildlife using the log — then they compiled it into one five-minute video.

Viewers see all sorts of critters crossing the log, including raccoon, black bear, chipmunk, bobcat, coyote, squirrel, fox, turkey, porcupine, muskrat, and a host of many different birds. Heck, there’s even a whitetail deer that comes along to feed on some stuff growing from the log.

To their everlasting credit, the makers of this video did not pollute it by adding a song. There is perhaps nothing more obnoxious than a bunch of manmade racket rattling around in the background of a video. Instead, we get the calming sound of flowing water and natural sounds made by some of the creatures. Nice.

I admit I did enjoy seeing the big bear’s paw slip off of the log and into the water. Doh!

Water levels vary, with the creek’s level usually pretty low — but at one point there was water roaring over the bridge log. Watching the squirrel leap over some flowing water was fun.

I think you’re going to like this.

USPTO launches the Expanding Innovation Hub, a new online platform to encourage greater participation in the patent system

https://ift.tt/2WHEiWK

The following post is republished from the USPTO Director’s Blog and is authored by USPTO Director Andrei Iancu and Deputy Director Laura Peter.

Red, yellow, and blue silhouettes of heads look left and right.

“To maintain our technological leadership, the United States must broaden our innovation ecosphere demographically, geographically, and economically.”—USPTO Director Andrei Iancu

Today, as part of Women’s History Month, the USPTO has officially launched the Expanding Innovation Hub (“the Hub”), an online platform available on the USPTO website that provides resources for inventors and practitioners to encourage greater participation in the patent system. The new platform is yet another step the USPTO has taken to broaden the innovation ecosphere, to inspire novel inventions, to accelerate growth, and to drive America’s global competitive edge. It builds on our SUCCESS Act report to Congress of 2019, as well as our Progress and Potential report on women inventors.

“Expanding Innovation” is part of the USPTO’s effort to inspire more women, minorities, veterans, and geographically and socioeconomically diverse applicants to join the innovation economy. Important pillars of that effort include education and mentorship. On the Hub, you will find the new Demystifying the Patent System Toolkit, designed to help innovators understand the process of obtaining a patent. Additional resources on the Hub include the Mentoring Toolkit, intended to assist organizations in establishing an infrastructure to connect experienced innovators with the next generation in their organization; and Community Group Resources, designed to help organizations establish an infrastructure to connect groups of employees with shared characteristics, interests, and goals.

These new tools are in addition to many other efforts at the USPTO to help expand the innovation ecosystem. We will continue to host a wide variety of events to amplify this message, such as Invention-Con and the Women’s Entrepreneurship Symposium. We have a pro se assistance program to help inventors who are not represented by counsel apply for patents. We have a pro bono network, and we also work with 60 participating law school clinics, all to help inventors and entrepreneurs secure free or discounted legal services. We provide a host of other online resources to help guide and educate inventors as well.

We also continue to expand our reach geographically. In addition to our headquarters in Alexandria, we have four regional offices in Detroit, Denver, San Jose, and Dallas, and 83 Patent and Trademark Resource Centers located in public, state, and academic libraries across the country. These centers not only offer a physical connection to valuable government resources, but they also offer regular programming, office hours, and staff trained to assist inventors and entrepreneurs with intellectual property (IP) research.

The USPTO also supports dozens of STEM-related programs that provide education about IP to young men and women. These include programs in partnership with the National Inventors Hall of Fame, such as Camp Invention, which is offered in school districts in every state, and the Collegiate Inventors Competition, which takes place each year at the USPTO; the National Summer Teacher Institute, which brings invention and IP into the nation’s classrooms; collaborations with historically black colleges and universities; the Girl Scout IP patch, which is available to Girl Scout troops across the nation; and so much more.

Now, with the new Expanding Innovation Hub on our website, inventors will have a central location to find information about all of our programs and resources.

America’s economic prosperity and technological leadership depend on a strong and inclusive innovation ecosystem. That is why it is so important to make sure all Americans have the opportunity to develop and protect their inventions, build thriving businesses, and succeed. It is therefore critical that industry, academia, and government work together to broaden our innovation ecosphere demographically, geographically, and economically. Please visit the Expanding Innovation Hub and check back often to engage with us in this critical endeavor.

There are many different ways you can go with your logo. you have probably identified a business by looking at its logo before, even if their name isn’t on the logo. There are some business logos that when you see them, you can immediately guess what that company does.

Your logo is a huge part of your brand’s identity, it’s probably the first impact on public perception and having a bad logo design could affect your business. World’s multinational companies can spend millions of dollars on their logos – like UK-based oil group BP. They’ve spent £136m back in 2000 when they introduced their current sunflower design.

Okay, we understand that there are people who don’t have enough budget, and they are just starting out. You want to get the most out of your business, and logos play an important role, especially if you are just starting and trying to get your name out there.

10 Must-Haves For Your Custom eCommerce Website

https://ift.tt/2vLFqgQ

Whether you are starting an eCommerce website or already have an existing one, it is crucial for you to provide quality service to your customers. Many people think that implementing cutting-edge features to the website can lead to conversions growth.

However, only an integrated approach is the key to converting your leads into customers. You should take into account all the details to provide an unforgettable customer journey for your user. Here are ten must-haves for your eCommerce website that can help you with it. Let’s get it started!

User-friendly interface

According to the research, you have up to 0-5 seconds to grab your customer’s attention. Take so much time and the customer decides to leave your website or not. Make sure that your website has a beautiful and modern design. However, more often than not, it is not enough to have a fresh look.

To engage with your customers, one has to think about usability and how easy it would be for a user to make their purchase quickly and effortlessly. Your website should be convenient and easy to use. Try to make it as simple as possible, avoiding unnecessary pages, buttons, or long business flows.

Moreover, following a “mobile-first” rule, your online shop should have a responsive design that works on all devices like tablets, mobiles, desktops, PC, or laptops and runs on all types of browsers.

Filtering and easy search

If you offer a wide assortment of products, it can be hard for customers to find products that meet their needs. The clear search capability is a must-have of every user-friendly eCommerce website. To make the customer experience better, provide the ability to filter products by categories, prices, sizes, colors, etc.

These things can help your visitors to find and purchase products in a few moments. The latest artificial intelligence technologies also allow you to render a tailored catalog using predictive algorithms based on previous purchases and views.

Informative pages

make a good ecommerce website
When customers get to your website, they expect to understand what you do and what kind of products or services you offer in a few minutes. No one wants to waste their time looking for the right information. The homepage should be the clearest and should be catchy, allowing your customers to feel like you know what they are looking for.

Besides, product pages should include all kinds of products you sell with photos. If you sell custom products, it is essential to have an interactive design tool that will provide your customers with a design proof. Also, include a short description of every product, size, colors, and prices.

It is also helpful to include information about available shipping methods — how long does it take and how much delivery costs. These are must-haves that come with any eCommerce platform.

Contact page

When we talk about an eCommerce business, it is essential for you to build trust with your customers. The contact page is one of the methods to create strong relationships with them. It is not necessary to create a separate page for the “contact us” feature.

You can place it in a visible part of your most visited page. It would be a good idea if you add not only your email or contact form but also your skype, phone number, and links to your business’ social media. The more ways to contact you, the faster customers will do it. Chat software where you can quickly contact your customers and even assist them with the choices on the site would work best.

Web to print tool

Do you know that personalization is a trend nowadays? Web to print tool allows your customers to buy custom things like t-shirts, business cards, jewelry, stickers, and other promo items. Furthermore, the whole process becomes automated.

You do not need to make many calls or send emails to discuss the ordered goods. Thanks to the automation, you can save costs and get more satisfied clients. Moreover, using the web to print tool makes you more competitive in the market.

Advanced payment

good ecommerce website
A wide variety of payment methods is a must-have for modern online shops. Customers value this because it is straightforward. They can pay in a few clicks and save their time. You can provide payment via PayPal, Apple Pay, or Amazon Pay — the most common, but it would be better to know your audience and consider adding those payment methods that they use regularly.

FAQ

If your customers face the same problems every day, try to make their life more comfortable and provide them the list of answers to frequently asked questions. FAQs can be helpful to make them feel more comfortable during the buying process. Plus this will build your customers’ confidence towards your business

Do not forget to add answers about the return process, how to recover a lost password as well as available discounts, coupons, and promos. People always check on products with limited offer discounts.

Client reviews

More than 85% choose an online shop or a certain product after reading reviews. Would you agree to deal with an online store that doesn’t have any review or one that only has bad ones? Adding this feature to your website can build trust, but it also does not mean that all reviews must be positive.

Negative reviews are more valuable than positive ones as they can also give you feedback whether certain product builds overall customer satisfaction. It shows transparency to your prospects, and you will not seem like a fake. You can send emails and ask to add reviews or use ready plugins.

Good site speed

If your site loads more than 3 seconds, you are a risk-taker. People do not like to wait. Low website speed has an impact on your online shop visitors’ experience. Besides, it can harm your ranking factor, and your Google positions will leave much to be desired.

Pay attention to speed on mobiles. You can consider adding AMP to your website as well. It loads faster than the regular HTML page and can lead to sales increase by more than 20%. Moreover, AMP provides a better user experience due to being mobile-friendly.

Similar products

Adding “you might like this” feature to your eCommerce website can increase your sales. If you provide this to your customers, it will work like magic. They would think then, “Oh, this company really knows me and my preferences,” and get more excited. Hence, customers’ loyalty and engagement increase. In most cases, they click on the related products you offer and buy them. Isn’t that what you want so much?

Now it is time to try making some changes and adding innovation to your eCommerce website to create an unforgettable shopping experience. Imagine how your visitors will be shocked when they see a user-friendly, convenient, fast, and modern website. They will order once and get back for returning orders building a long-term commitment. It can be the beginning of your business prosperity!

You Can Virtually Tour the Winchester Mystery House For Free While It’s Closed Due to COVID-19

https://ift.tt/399PD4q

Like many other places around the country, the Winchester Mystery House is closed now due to the COVID-19 pandemic. Instead of physical tours, the house is offering a 40-minute video tour of the property for anyone that’s interested.

The house’s website says that it is offering free video access until April 7th, the day the Bay Area’s current “shelter in place” order is set to expire. For those that still want to visit, the house is also offering a ticket voucher that can be used anytime in the future, with no blackout dates or restrictions, so it can continue to pay its employees while its doors are closed.

The Winchester Mystery House is a mansion located in San Jose, California. Constructed in 1884, the property is said to be haunted by the ghosts of people killed with Winchester rifles, which were the creation of its original owner’s widow Sarah Winchester.

The house was under construction constantly from 1884 to 1922, some say without interruption 24 hours a day, until Sarah Winchester’s death in September of 1922. As you might imagine, the house has a rather unusual construction.

Before the 1906 earthquake, it was 7 stories high, but now it is only four. There are 1616 rooms, including 40 bedrooms, 2 ballrooms, 47 fireplaces, two basements, and three elevators and is made out of a variety of materials, some more unusual than others.

It’s definitely a peculiar thing to look at, especially in person, but if you’re looking for a way to kill a bit of time while you’re at home it can be a fun and odd piece of history to look at.
