Open IP over VHF/UHF #PiDay #Radio #RaspberryPi @Raspberry_Pi

Fri, 14 Aug 2020 13:40:43 GMT

The Rowetel blog discusses sending Internet Protocol (IP) traffic over VHF and UHF radio frequencies.

My initial goal for this work is a “100 kbit/s IP link” for VHF/UHF using Codec 2 modems and SDR. One application is moving Ham Radio data past the 1995-era “9600 bits/s data port” paradigm to real time IP.

I’m also interested in IP over TV Whitespace (spare VHF/UHF spectrum) for emergency and developing world applications. I’m a judge for developing world IT grants and the “last 100km” problem comes up again and again. This solution requires just a Raspberry Pi and RTLSDR. At these frequencies antennas could be simply fabricated from wire (cut for the frequency of operation), and soldered directly to the Pi.

See the article here and the GitHub repo for this project.

CurveBoards: Integrating Breadboards into Physical Objects @MIT_CSAIL

Fri, 14 Aug 2020 13:30:52 GMT

CurveBoards are breadboards integrated into physical objects. In contrast to traditional breadboards, CurveBoards better preserve the object’s look and feel while maintaining high circuit fluidity, which enables designers to exchange and reposition components during design iteration.

Breadboards are widely used in early-stage circuit prototyping since they enable users to rapidly try out different components and to change the connections between them.

While breadboards offer great support for circuit construction, they are difficult to use when circuits have to be tested on a physical prototype. Since breadboards are box-like shapes, they distort the look and feel of the prototype when attached onto it and can interfere with user interaction during testing. In addition, they limit where electronic components can be placed on the prototype since the area for circuit construction is limited to the size of the breadboard.

We present a new electronic prototyping technique called CurveBoard that embeds the structure of a breadboard into the surface of a physical prototype (Figure 1). In contrast to traditional breadboards, CurveBoards better preserve the object’s look and feel while maintaining high circuit fluidity, which enables designers to exchange and reposition components during design iteration.

Increasing Swap on a Raspberry Pi #piday #raspberrypi @Raspberry_Pi

Fri, 14 Aug 2020 13:00:56 GMT

via PiMyLifeUp

The swap file is used to increase the system’s total accessible memory beyond its hardware capabilities.

This means that when all of the Raspberry Pi’s RAM is exhausted, it can start using the swap file as memory instead.

The addition of more virtual memory allows the system to deal with more memory intensive tasks without running into out of memory errors or having to shut down other additional packages.

Processing Raw Image Files from a Raspberry Pi High Quality Camera @Raspberry_Pi #PiDay #RaspberryPi

Fri, 14 Aug 2020 12:00:37 GMT

Here’s a walkthrough on how to process raw image files using Raspberry Pi and a Python utility called PyDNG, available on github. Here’s more from Raspberry Pi Blog:

The raw image is sometimes likened to the old photographic negative, and whilst many camera vendors use their own proprietary formats, the most portable form of raw file is the Digital Negative (or DNG) format, defined by Adobe in 2004. The question at hand is how to obtain DNG files from Raspberry Pi, in such a way that we can process them using our favourite raw converters.

Many readers will be familiar with the raspistill application, which captures JPEG images from the attached camera. raspistill includes the -r option, which appends all the raw image data to the end of the JPEG file. JPEG viewers will still display the file as normal but ignore the (many megabytes of) raw data tacked on the end.

Rainbow Metaclock #piday #raspberrypi @Raspberry_Pi

Fri, 14 Aug 2020 11:00:27 GMT

via ferrithemaker on instructables

Some time ago I saw a Tweet from the arduino official account talking about an amazing project called “clockception!”, the project seems to be a digital clock created using 24 analog clocks! The video run for a few seconds and I did not have the tech details, but I was amazed! So, I decided to create a new project from scratch inspired in a similar concept and visuals but more colorful using processing and a Raspberry Pi.
At first, maybe it’s difficult to understand what is “a digital clock formed by 24 analog clocks”. A picture is worth a thousand words.

This Office Bell Ringer is Controlled by Slack #piday #raspberrypi @Raspberry_Pi

Fri, 14 Aug 2020 08:00:21 GMT

How great is this project from Alex Meub!?

Have you made a Slack / Raspberry Pi project? We’d love to hear about!

At my company, it’s a tradition to say “ring the bell” when we sign a new customer, release a new feature or receive other positive news, big or small. When we hear the large bell ring in the center of the office, we know that something good just happened. It’s been a great way to celebrate the wins we have together.

The problem is that our remote team members are completely left out of this experience.

Experimental Resin 3D Printer Updated! #piday #raspberrypi @Raspberry_Pi

Fri, 14 Aug 2020 06:00:00 GMT

Clem from Element14 has some fun trying out a unique 3D printing set up based on the Raspberry Pi 4!

From Element14 Presents:

Clem has built a giant resin based 3D printer concept in a previous video, and today it is time to put the concept upside down! The people on the element14 community gave him a lot of advice and ideas to make his idea finally work as it should! Clem builds a second iteration of his 3D printer using daylight resins and easily obtainable parts. The new Raspberry pi 4 8 GB reduces slicing times and makes for a more responsive GUI on this experimental 3D printer! Now its time for the community to take his findings and iterate for a bright future of cheap huge 3D printers!

Native American Code Talkers Day #NavajoCodes

Fri, 14 Aug 2020 05:30:23 GMT

Established in 1982 by President Ronald Reagan, National Navajo Code Talkers Day honors the service of the Navajo Code Talkers and their efforts in World War II.

For thousands of years, American Indian men have protected their communities and lands. “Warrior” is an English word that has come to describe them. However, their traditional roles involved more than fighting enemies. They cared for people and helped in many ways, in any time of difficulty. They would do anything to help their people survive, including laying down their own lives.

Warriors were regarded with the utmost respect in their communities. Boys trained from an early age to develop the spiritual, mental, emotional, and physical strength they would need to become warriors. Many tribes had special warrior societies, which had their own ceremonies, songs, dances, and regalia that they wore. Usually, a warrior had to prove himself before being asked to join a warrior society. It was a great honor to be chosen in this way.

Despite everything that American Indians had endured in the past, the warrior tradition—the tradition of protecting their people—called many of them to serve in the United States military. They cared about their communities and the lands on which their people had lived for thousands of years. Many of them also served out of a sense of patriotism, wanting to defend the United States. For some American Indians, the military offered economic security and an opportunity for education, training, and world travel.

More than 12,000 American Indians served in World War I—about 25 percent of the male American Indian population at that time. During World War II, when the total American Indian population was less than 350,000, an estimated 44,000 Indian men and women served.

In World War I, Choctaw and other American Indians transmitted battle messages in their tribal languages by telephone. Although not used extensively, the World War I telephone squads played a key role in helping the United States Army win several battles in France that brought about the end of the war.

Beginning in 1940, the army recruited Comanches, Choctaws, Hopis, Cherokees, and others to transmit messages. The army had special American Indian recruiters working to find Comanches in Oklahoma who would enlist.

The Marine Corps recruited Navajo Code Talkers in 1941 and 1942. Philip Johnston was a World War I veteran who had heard about the successes of the Choctaw telephone squad. Johnston, although not Indian, had grown up on the Navajo reservation. In 1942, he suggested to the Marine Corps that Navajos and other tribes could be very helpful in maintaining communications secrecy. After viewing a demonstration of messages sent in the Navajo language, the Marine Corps was so impressed that they recruited 29 Navajos in two weeks to develop a code within their language.

Meet the impresario behind the DJ-as-coder music revolution #piday #raspberrypi @Raspberry_Pi

Fri, 14 Aug 2020 04:00:00 GMT

Quick profile from Fast Company about Sam Aaron of Sonic Pi. Its rad to see the growth of, not only the Pi, but Pi based products!

Via Fast Company:

He had hoped that his creation, developed in conjunction with the Raspberry Pi Foundation, might inspire kids to code, but instead he accidentally breathed new life into a small but avid artist community of live-coder DJs, who until then had to use complex tools and code that bore no obvious relationship to the sounds being produced. Sonic Pi, however, is so expressive that many live coders actually pro ject the code on a big screen during sets so everyone can see how the music is being generated.
