Making Your Own Custom Shortcut Keyboard

Article Featured Image

Via Hack-a-Day comes this cool shortcut keyboard project. Alex, an engineer at SparkFun, wanted to create a keypad populated with shortcut commands for the Autodesk Eagle CAD software program he uses every day to design circuit boards. On his Github page, he describes the project:

The keyboard has a 4×4 matrix of cherry MX switches, which are connected to the SparkFun Pro Micro. Each key can send either a keyboard or mouse command to the host computer thanks to the improved HID Arduino Library. Rotary encoder support was provided by the Teensy Encoder Library. The software is currently configured as an Eagle shortcut keyboard, where each button corresponds to an Eagle command. The left rotary encoder controls the computer’s volume, and the built in encoder switch for mute. The right encoder controls the grid spacing, and the encoder switch will toggle between imperial and metric units.

The Cherry MX key caps were printed on a Lulzbot Mini 3D printer. The key caps Alex used he got from this Thingiverse page.

As you can see, he also has two rotary encoders at the top of the pad. The knob on the left controls the volume on his computer, with the push-button on the knob functioning as a mute. The knob on the right allows him to control grid spacing in Eagle and the push-button allows Alex to switch between imperial and metric measurements.

While this pad was purpose-built for Eagle CAD, you could obviously adapt this to any design or other software you work in that can be greatly optimized by setting up shortcuts and macros. And as Hack-a-Day points out, you could also upgrade the keys with capacitive touch sensors and Bluetooth could be added to make the pad wireless. You could even double the assigned functionality of the keys with a Double Action Keyboard upgrade.

Ancient Culture + Latest Tech = Maker Faire Xi’an

Article Featured Image

How much do you know about Xi’an, China? Perhaps the name is new to you, less commonly heard than, say, Beijing, Shanghai, or — particularly in maker circles — Shenzhen. This 3,000-year-old city was the capital city for 1,077 years, through 13 dynasties. Among other wonders, it’s home to the absolutely incredible Terracotta Army, a collection of full-size funerary statues including more than 8,000 soldiers, along with chariots and over 600 horses, belonging to the first emperor of China and dating back to the late third century B.C. In beautiful juxtaposition, this weekend the city of Xi’an will also become home to the first ever Maker Faire Xi’an, where thousands of years of making will meet and greet the Maker Movement.

We have to share at least one picture of the Terracotta Army:

The Maker Faire Xi’an team put together a lovely video that shows the international flavor of Maker Faire and announces their Faire:

We spoke with lead organizer and curator Kevin Lau, who is no stranger to the Maker Movement. Lau has worked extensively with electronics and hardware startups through Seeed Studio, co-founded the Guangzhou Hackerspace, was formerly CEO of Chaihuo Makerspace, and helped bring the first Maker Faire to China in Shenzhen. He shares, “Maker Faire is more than a party. It’s a seed planted in a city, striving to grow into a big tree that yields fruits for the local maker ecosystem. It helps to draw global makers closer. It creates a stage for potential partnerships. We can wait to see this ancient city unleash its power of making.” The inaugural Maker Faire Xi’an will consist of five parts: Maker Bazaar, Maker Forum, Maker Installation, Maker Workshop, and Maker Performance.

The amazing drawings featured in this post are by local young maker and artist Icy Tan.

1. Why did you decide to organize a Faire in Xi’an?
I chose Xi’an for a couple of reasons. Xi’an is a knowledge-based economic and innovation center in Asia, the starting point of the new silk road under the national “Belt and Road” initiative, as well as a magnet to more than 200 Fortune 500 enterprises who have established their R&D centers here. This includes Intel, IBM, Schneider Electric, Siemens, GE, Bosch, Applied Materials, Toshiba, Hitachi, NEC, Brother Industries, EMC, Emerson Electric, and more.

I believe holding a Maker Faire here will ignite new sparks between cutting-edge technologies, the maker spirit, folkcraft, and traditional Chinese culture. Maker Faire Xi’an 2017 is themed “Live to Make” because we want to give more attention to the grassroots makers who could spread maker culture even further and encourage more people to join the global league of makers. Here in Xi’an, there are so many people like this to be found.

2. What organizations are involved with putting on the Faire?
First of all, I want to thank Maker Media for allowing us to hold Maker Faire Xi’an and for creating one of the best events on Earth. I’ve definitely learned a lot from other Maker Faires. Those experiences later gave birth to the idea of holding Maker Faires in Chinese cities. I also want to thank the local government. Without the great support of the city of Xi’an, Maker Faire Xi’an would not be happening. I also want to thank the Publicity Department of the Communist Party Committee of Xi’an, Xi’an Administration of Science and Technology, and the Administration Committee of Qujiang New District. They offered a great deal of help to make this happen.

I have quite a bunch of strategic partners who have been taking care of the amazing content and details. They are MakerBeta, Midou Education, Maywa Denki, British Council China, Little Inventors, and OhMy Design. During the event, we’re going to have the involvement of ThoughtWorks, Sony, DJI, ProAdvance, and Fab Lab (Beijing). Media outlets including Vice, Modern Weekly, DesignBoom, 36Kr, CSDN, BGD Design, Xi’an Daily, and Sanqin News are going to cover this event.

3. Tell us about the maker community in Xi’an.
Xi’an has a great climate for makers. There are 63 universities and colleges, most of them with engineering, design, science, and technologies-related backgrounds. It’s the third largest education base in China, graduating more than 300,000 students annually. The culture of making has found its place here since a long, long time ago.

You will see “Dynamic Kites” manufactured by 79-year-old Zhang Tianwei [pictured above], listed as an intangible cultural heritage in Shaanxi Province; a paper-making mill originating from the Han Dynasty; the “Li Yi Cheng” Wooden Cart that has existed since 1897 in the Qing Dynasty; a mini Bell Town (Xi’an’s landmark) made of sorghum, a type of northern crop; and more projects with Chinese characteristics. You can also find a younger maker community here, featuring 3D printing, smart hardware, IoT, etc. Plenty of makerspaces are visible both outside and inside schools. Our local partner, MakerBeta, is a perfect example. They not only post videos about makers online, but they do offline activities as well.

4. What can we expect to see at the Faire?
We’ll have the creator of Maker Faire Dale Dougherty, British stylist Dominic Wilcox, Swiss bio-hacking master Marc Dusseiller, American futurist and artist Steven M. Johnson, and more. You’ll also see “Little Inventors,” which helps kids bring their ideas to reality; the Nerdy Derby no-rules miniature car building and racing competition; Ars Electronica winner, Eric Siu’s “Touchy” [pictured below]; Sino-Japan FPV racing; Japanese art design and performance band Maywa Denki [pictured above]; Canadian tech-fashion show MakeFashion; EepyBird’s Coke and Mentos performance, created by two American doctors, the most well-received activity at Maker Faire Bay Area; and The British Council, along with eight excellent British makers, will their experiences, which you won’t want to miss.

5. What has the community reaction to the upcoming Faire been so far?
Our event would not take place without the support from the local maker community and the government. The maker spirit that we celebrate and cherish resonates with them very well. We chose the theme “Live to Make” in the hope of inspiring more people to make and create. This is something they feel excited about.

6. How many maker exhibits and attendees do you anticipate?
This is a free event. Based on the scale we achieved in Shenzhen, we estimate that there could be more than 100,000 people attending. We will have 160 exhibitors coming from all over the world. We also have specially invited projects. The number of perspective attendees and projects continually rises.

Xi'an

7. What would you say uniquely defines the Xi’an maker community?
I think Xi’an is a city that embraces the past as well as the future. Xi’an is a very unique city. It’s geographically in the center of China and in the same timezone as Beijing. It has a rich history of being the capital for 13 dynasties. The most prosperous one was the Tang Dynasty, when China became the first country in the world to reach 1 million inhabitants. Many craftsmen have passed their skills down from generation to generation. You can still see traces from the far ancient time in many modern works by the local makers. And there are millions of talented young people here to create a better future. Here, you will see the past. And here, you will see the future.

Transforming a Game Boy Camera into a Tool for Astrophotography

Article Featured Image

Alex Pietrow describes the Game Boy Camera as “a monochrome, 2bit, 128×112 pixel CMOS camera from 1998 that was especially made to work with the Nintendo Game Boy. It is well known as the first affordable portable digital camera and was actually considered decent in its day.”

Now, nearly 20 years later, we have digital cameras that dwarf its capabilities. However, the venerable Game Boy cams are still readily available on the used market. As such, they are fun tools for experimenters to tinker with and use in ways that would likely surprise the original designers of this device. Pietrow, a master’s student in Astronomy and Instrumentation at Leiden University with a keen interest in old 8-bit games, decided to take this one step further and attempt to photograph celestial objects with it.

In addition to an academic interest in astronomy (he’ll soon be pursuing his doctorate in Solar Physics at Stockholm University), Pietrow gives tours of the Leiden University’s Old Observatory in the Netherlands, which was in use from 1860 to the 1970s and still houses its original telescopes. One perk of this job is that he can use the antique telescopes there for personal observation. Naturally, he set to work attaching his Game Boy Advance SP, along with its camera to an antique telescope, built in 1838.

Physically attaching the Game Boy to the scope was the biggest challenge of the build, since the camera doesn’t have a standard shape to fit into an eyepiece or normal photographic equipment, much less something built nearly 200 years ago. To compensate for this mismatch of parts, he squeezed the GameBoy into a mount meant to hold a phone, and lined it up after quite a bit of trial and error.

Another challenge to this build, is that the camera itself features only a 128 x 128 sensor—which is further limited to storing 128 x 112 pixels—and 2-bit color depth—which works out to only four grayscale values. Though this limitation is challenge in the sense of getting what most might consider “good” images, this type of limitation is a huge part of what makes hacking old hardware interesting and the results memorable.

The final challenge was the environment itself, which both amateur and professional sky observers are certainly familiar with. According to him:

The entire project took about 2 months, but mostly because bright, cloudless nights are rare and some trial and error. In a country with better conditions this should be a lot easier. This project made me appreciate the field of astrophotography more than before, as even seasoned photographers would have trouble with this. But it is great fun!

As seen in the photos below, the results are low-resolution, but spectacular for what they are. Due to a cloudy sky, the setup was first tested on a nearby church tower’s clock, which can be seen below next to a modern photo of it. In later photos he was able to photograph Earth’s moon, complete with craters.

Another photo seen here even allowed him was even able to pick out two of Jupiter’s moons, pointed out via red arrows in one of the images. The other dots in that photo are due to photographic noise caused by light pollution, which is a factor in any city.

Though perhaps Nintendo would be surprised at this modern use, one could only imagine the disbelief of the telescope’s original creators, who constructed it in 1838. Future plans for this setup include observing the Sun through a filter, as well as Saturn, so hopefully we’ll get to see even more spectacular 8-bit space images in the future.

Perhaps we’ll even see more Game Boy telescope setup images or black and white selfies!

San Diego’s Vintage Tech Makers Inspire Modern Educators

It’s well known in the maker community that Maker Faires are an exciting way to grab a sneak peak into what is new and exciting in the minds of tinkerers. While Maker Faires have been going on worldwide for several years, there is incredible value for teachers looking to shake up their classroom experience. The hands on project ideas that these makers create have the potential to be hugely beneficial in generating new curriculum ideas for the upcoming school year. Take the recent Mini Maker Faire in Vista, California that occurred over Fathers Day weekend. It was an amazing showcase and display of local makers doing what they do best — showing and telling.

These were not the makers who we know so well. Curators and connoisseurs of Raspberry Pi, Arduino, and 3D printing. Located at the Antique Steam Gas Engine Museum is a treasure trove of the lost arts of vocational training or now called career & technical education (CTE). This place serves as a great example of going back to basics when it comes to teaching innovation and invention through project-based learning. One attendee humorously said, “This place feels like we are in the time when ‘making’ was just simply called ‘living.’” He was on to something. What is unique about the Antique Gas and Steam Engine Museum are the collection of machines, many from the early 20th century, that hobbyists, engineers and mechanics have all rehabilitated and made operable. This wasn’t just a regular day for modern makers since it brought together new makers and old makers alike, a convenient theme of this year’s mini faire, “Where new makers and old makers join forces!”

We met John Sawyer from the Cigar Box Guitars. He created a DIY cigar box guitar kits that sounded superb and easy to make at a price point that didn’t break the bank. He demonstrated some of the ways he decorates his guitars but using the scientific Lichtenberg principle to create beautiful and unique patterns.

We met Jeff Sparksworthy of the San Diego Argonauts who discussed World War II battle ship replicas and the painstaking detail that they took to build these beauties, only to destroy them on the battlefield for our viewing pleasure.

Or take the handloom weavers guild at the museum, a collective of weavers who make textiles by using antique looms. They restore old machines, get them working, learn how to use them, and keep them working. I spoke with one teacher who hopes to bring her class to learn this old style of making one day. May of the weavers hope to teach the next generation the lost art of weaving.

There are also the California Blacksmith Guild, a workshop group that offers classes to teach the art of blacksmithing. The idea of using your hands and body completely in a way that makes you realize the hard work and effort you are putting into something is powerful to see. It makes writing this blogpost in the comfort of an air-conditioned airplane seem sad and pathetic. Where is the grit in that?

There are lessons, history, and curriculum associated with making that develop a truly authentic and meaningful student and teacher experience. Can we begin to teach through experience in a way that makes the lesson relevant to and would resonate with the student? Teachers can start on the path of project based learning and maker education by simply observing other makers in action. This will allow them to fully embrace the culture, spirit, and application of making inside and outside the classroom.

Come to a local faire and see what it’s all about. Guaranteed there will be some creative ways to reignite the energy, imagination and authenticity in your classroom.

Hack Your Car into the Future with an LED Heads-Up Display

Article Featured Image

Frank Zhao wrote in to show us about this deceptively simple looking modification he made to his car. He wanted to bring a bit of the future into his driving experience with a HUD (Heads Up Display). As you can see in the video above, the best example of these is the cockpit of a state-of-the-art fighter jet. There is additional data displayed directly in your field of view to allow you to keep your eyes on the target, or road.

This type of display is usually created by angling a piece of glass so that you can see through it, but also see the reflection of some lights or an instrument panel at the same time. Most cars have a windshield that is conveniently already tilted at an angle that works! Frank saw this and got to work.

His modification exists as an LED strip mounted to his dash in a custom 3D printed case. The case has walls to keep the LEDs themselves from being visible to Frank or other drivers. However, the top of the case is open, allowing Frank to see the reflection of the LED strip quite clearly on his windshield. He’s tapped into the OBDII port of his car to pull information, such as speed, and then written a bit of code to create a useful display from those LEDs.

It is programmed to have three different modes: voltmeter, tachometer, and speedometer. The mode switching is “context aware”: When the car is moving, the mode changes to speedometer. If I rev the engine without the car moving, the mode changes to tachometer. When the engine is off, the voltmeter shows me the car’s battery voltage. When transitioning between the modes, there’s a few preset transition animations that are randomized. When the car is off, the circuit goes into sleep mode.

Since this is mounted on his dash, he also has to take into account the amount of sunlight. Frank has added a photoresistor that can detect the amount of light and adjust the LED brightness on the fly. This is most important at night when the LEDs have the potential to actually obstruct his view and need to be dimmed considerably.

You can find more information about both using and building the system on Frank’s site. He’s giving away the plans and code as well!

Abstract Painter Builds Clever Machines to Deposit Paint

Article Featured Image

I have always been fascinated by mechanically-assisted forms of painting and other types of automated or semi-automated art production. For instance, one of my favorites is Giuseppe Pinot-Gallizio, an Italian painter who, in the 1950s, was part of the radical French art group Situationist International. A former chemist and inventor, Pinot-Gallizio developed a mechanically-assisted method of painting on moving rolls of canvas that he dubbed “industrial painting.”

Working in a similar vein of invention and experimentation (Pinot-Gallizio called his studio “the lab”), Callen Schaub creates his own mechanical means of depositing paint onto canvas (or onto people and objects). The YouTube description for a CBC Arts profile of Schaub explains:

Toronto-based artist Callen Schaub invites us into his studio to see how he uses swinging troughs, paint can pendulums, and bicycle parts to create his signature abstract paintings.

Callen Schaub’s practice draws from a rich history of artists using spinning and dripping techniques — from Damien Hirst to Jackson Pollock. But Callen has invented his own homemade devices that include swinging troughs, paint can pendulums and bicycle parts that help him create his signature works. In this video, Callen takes you inside his paint-splattered studio for a look at how he makes his dazzling works of art.

Callen using his paint bucket pendulum to swing paint onto canvas.

The spin machine, Schaub’s go-to device, is a hand-cranked canvas spinner he made out of bicycle parts.

With the swinging trough technique, Callen deposits paint into a trough hanging above the canvas and then swings the trough over the canvas to deposit the paint.

Cultivating a Neighborhood Garden as a Community Organizing Hub

Article Featured Image

Chickens are clucking, ducks quacking, and a group of kids are kicking a ball around on the schoolyard across the street. It’s almost easy to forget that Bottom’s Up Community Garden is in the middle of a major metropolitan area, nestled on a street corner in the Lower Bottoms neighborhood of West Oakland, California.

In San Francisco Bay Area’s patchwork of both affluent and disadvantaged neighborhoods, West Oakland is the latter. Jason Byrnes, one of the garden’s founders, says that in terms of food availability, the Lower Bottoms is a desert. There’s no grocery store. Even the 99 Cents Only store, which did have some produce, is no longer there. Seneca Scott, an organizer for the garden, explains that in West Oakland, “theft is rampant. You’ll see car windows that have been busted out, you’ll see tape over people’s windows.”

It’s not just food and community that the garden provides — it’s a haven. “I like to think we’ve added a lot to this neighborhood,” says Scott. “People tell us all the time that they feel safer.”

Plants with Purpose

Byrnes founded Bottom’s Up three years ago. He started with a few abandoned plant beds, now overflowing with produce on the roughly 3,500-square-foot plot. He also runs a few other community lots, with goats, chickens, and ducks (the animals will eat anything people don’t want to), and a beehive. They sell weekly batches of produce to a few local restaurants — The Cook and Her Farmer, Swan’s Market, Desco, and Flora — all in Oakland.

He says he had to do it. “I don’t really have a choice. If I’m not growing something I won’t feel right about myself.” Byrnes grew up gardening, but often felt like the “community” of community gardens was absent. “There were a lot of isolated beds — it was like the opposite of a community garden.” He would give his neighbors extra produce from his personal garden while living in Santa Rosa. “After a year or two, all the neighbors had small gardens and we all knew each other by name. I realized it could be a lot more than just a garden,” he says. “Every farm becomes a community farm if you’re in a strong community.”

Scott, on the other hand, used to be the East Bay director for the SEIU 1021, a labor union. He doesn’t have an agricultural background. He just likes to cook and wanted to get involved. “One of our philosophies” says Scott, “is to plant yourself and grow your roots.” It’s about consistently dedicating your time, about weathering yourself against the storm. That won’t happen overnight, but it will happen.

Cultivating Culture

Scott and Byrnes have few rules for the garden, if any. There’s no org chart; it’s not hierarchical. But they do have different levels of involvement — they’re the main organizers, they have about half a dozen regular volunteers, and 317 members on their Facebook page. Plus the neighborhood benefits from their work directly and indirectly.

“If you grew something, we will protect your investments and make sure you get something for your work, but it’s not yours. This is ours. No one has any excuse that their ‘ownership’ of this place supersedes the community,” Scott explains.

What you do at the garden is for the common good. Sometimes they conduct workshops, or volunteers will, if they have knowledge to share. It doesn’t have to be about gardening. That’s the totally inclusive, “sky’s the limit” model that Byrnes and Scott are following — anyone can come and get involved and initiate anything they want: yoga workshops, poetry readings, you name it.

For a brief stint, there was a café operating out of the garden that opened every single day at 7am. Scott pinpoints this as the tipping point that got the entire neighborhood involved. “People started coming as customers, we started throwing parties, and it became a community hub,” he says.

It got so popular, you can now search for the Bottom’s Up Café as a geotag, even though it doesn’t officially exist anymore — the city gave a warning due to lack of permits. After that came Oakhella, a recurring DIY hip-hop music festival put on right there between the planter beds. They’ve thrown six so far since the beginning of 2016.

“I think what’s great about this place is that it acts as a magnifier for anyone’s talent,” says Byrnes. “We couldn’t have started the café in a random abandoned lot. Oakhella wouldn’t have worked.” Not without the energy and vision that came from the group of people involved at Bottom’s Up. Scott remarks how special it is that everyone benefits from everyone else, that everyone adds value. “But we also hold each other accountable,” he says, “It’s not for the faint of heart. Don’t disrespect anyone, but we don’t always have to agree.”

And dissent can be good — productive, even. Byrnes and Scott are highly opinionated, and they’re thinking far beyond their plot of land. Scott says Bottom’s Up is very old school, but also futuristic in their philosophies. He mentions The Jetsons and The Flinstones: taking technology that’s valuable to us, and looking at what’s sustainable. He explains that the technological landscape is changing the way we work, and the way we view work. “Technology’s gonna move. It doesn’t have a soul or any empathy. We’re responsible for that. So if the path we’re headed is that people don’t work anymore because there’s no work to do … What do you do? You spend more time on your community. On your art. On your personal expression. We do that all day.” He says “the goal isn’t profit so much as showing people how localized agricultural systems work.” Right, agricultural systems. It must mean more to Scott than just growing plants, because they’re accomplishing so much more than that.

Organizing Organically

Sitting in the garden on a quiet Wednesday afternoon, under the baking sun on this tiny plot of land, it’s hard to imagine 500 people squeezed in here around a ramshackle stage for Oakhella on April 30th. (The Oakhella tag on Instagram proves it, though.) There was virtually no damage to the plant beds, a nod to the communal respect that governs this space.

“As an organizer, we help enhance what a community garden can be by bringing a music festival,” says Scott. “It really pushes the boundaries of what people consider as a community garden.”

Scott says he’s just sort of learned along the way — how to grow plants, how to build a table, how to organize. The organizing came from simply getting involved, and from observing other failed and successful attempts at social programs. He mentions “The Village,” a grassroots homeless camp at Grove Shafter Park that greatly benefited the homeless population — until the city of Oakland cited violations and tore it down at the beginning of the year. The city then backed its own homeless camp, which promptly burned down May 1. It’s a stark indication that sometimes what communities need aren’t administrative measures, but organizers from their own ranks.

Oakland, of course, has a long history of political and administrative clashes with community organizers. The Black Panthers and their Free Breakfast Program were highly influential in establishing West Oakland’s history of urban agriculture. “As long as [the government] controls a commodity,” says Scott, “they control the people. Anything that you can get to take control over your commodity is worthwhile. When the Black Panthers formed, this neighborhood was in the exact same place it’s in now.”

So what do Scott and Byrnes want next, exactly? “Getting organized will help, and involving more people, but what we really want people to do,” says Scott, “is go start your own garden.” “So we can come to your Oakhella,” chimes in Byrnes. “We’ll help you out,” says Scott, “but you gotta take the ownership. First of all, what is your ‘Why’? What are you doing, and why? Next,” he says, “you need to take a skills inventory. [Jason and I] can take a dozen people and figure out what everybody’s best at. When I first came here, you know how I contributed? I cleaned up. I brought water. I sweep up. Just get together and figure out what you’re good at and drop the ego.” He mentions, “we both have big egos. We’ve had some big fights here, cause we care about it.”

Byrnes and Scott are plenty aware of injustice, from the smashed windshield in their neighborhood all the way to the global consolidation of wealth. It’s all connected. The world is a scary place, and there’s a lot of uncertainty about what will happen next. “Until then,” Scott says, “this is what you do. Have parties. Invest in your neighbors. Celebrate. Live life. Grow some veggies.”

After all, everybody’s gotta eat.
