If you want video support on your project, you might start from a device like a Raspberry Pi that comes with it built in. [Kevinhub88] doesn’t accept such compromises, so he and his Black Mesa Labs have come up with a whole new way to add video support to devices like the Arduino and other cheap controllers. This project is called Mesa-Video, and it can add digital video at a resolution of up to 800 by 600 pixels to any device that has a single serial output.

The video is created by an FT813, a low cost GPU from FTDI that offers a surprising amount of video oomph from a cheap, low power chip (he has demoed it running from a lemon battery), meaning that he is hoping to be able to sell the Mesa-Video for under $50.

However, Mesa-Video is just the beginning. [Kevinhub88] wanted to get around the problem of stacking shields on Arduinos: add more  than one and you get problems. He wanted to create an interface that would be simpler, faster and more open, so he created the Mesa-Bus. This effectively wraps SPI and I2C traffic together over a simple, fast serial connection that doesn’t require much decoding. This means that you can send power and bi-directional data over a handful of wires, and still connect multiple devices at once, swapping them out as required. You could, for instance, do your development work on a PC talking to the prototype devices over Mesa-Bus, them swap the PC out for an Arduino when you have got the first version working in your dev environment. Is the Arduino not cutting it? Because Mesa-Bus is cross-platform and open source, it is easy to swap the Arduino for a Raspberry Pi without having to change your other devices. And, because all the data is going over a simple serial connection in plain text, it is easy to debug.

It’s an ambitious project, and [Kevinhub88] has a way to go: he is currently working on getting his first prototype Mesa-Bus devices up and running, and finalizing the design of the Mesa-Video. But it is an impressive start and we’ll be keeping a close eye on this work. Hopefully he can avoid that head crab problem as well because those things are as itchy as hell.

05emile

Julian Hespenheide is an interaction designer based in Germany who submitted to Arduino blogpost a writing machine called émile. It’s an interactive installation created in collaboration with Irena Kukric, David Beermann, Jasna Dimitrovskais and using Baudot code - a binary 5-bit code, predecessor of ASCII and EBCDID – intended for telecommunication and electronic devices, representing the entire alphabet.

It runs on Arduino Uno and  translates the bauds (/?b??d/, unit symbol Bd) into moving objects that are being sent over physical tracks in order to illustrate  a simple computational process of 5-bit binary information transmission:

The machine was built in six days with four people. In our group we came to the conclusion, that not every process in a computer is really transparent and it already starts when you type a simple letter on a keyboard. To unwrap this “black box” of data transmission, we set our goal to build a small writing machine where you can literally see bits rolling around. After some research we got back to the beginnings of Telefax machines and data transmission using Baudot-code. We then quickly designed punchcards and mapped them to a slightly altered baudot code table and cut them with a laser cutter from 5mm plywood.
Whenever a marble hits a switch, a short timer goes off and waits for input on the other switches. If no other marbles are hitting those switches, we finally translate the switches that have been hit into the corresponding letter.

Take a look at the machine in action:

Measure time like an egyptian with an Arduino hourglass

Todo is the italian design consultancy and creative agency taking care of Arduino and Genuino brand identity and interviewed in this previous blogpost.

Last year, among other projects, they worked on an unconventional communication campaign to narrate the re-opening of the well-known Turin’s Egyptian Museum, displaying a collection of over 30,000 ancient pieces.

The campaign’s goal was to hold people’s attention over six months before the official opening of the Museum and be able to speak to a broad national and international audience.

TODO created an open air installation composed by an almost-4-meter-tall hourglass (with a hidden mechanism running on Arduino) that had to work day and night, for six months and over the winter. According to Wikipedia, this hourglass could be the 4th biggest of its kind in the world!

The main challenge was that they had to make sure that the very last grain inside the hourglass would fall on the day of the Museum’s inauguration.

The installation was created thanks to many collaborators among which Gabriele Gambotto who developed the electronic part based on the Arduino Yún on which they added a custom shield ( See pic below), connected to various sensors and a precision scale. The sand-like material passed through a valve and a long screw conveyor controlled by a mot

Take a look at the video of the ‘Hourglass Countdown’ and to see it in action:

In an indoor area of the museum an interactive display case was the other face of the campaign revealed to the audience:

A series of replicas of ancient Egyptian finds were covered in sand, and users could interact with the system by choosing the spot they wished to unveil, blowing into a microphone, and having their breath converted by a small robot arm, which placed itself in the exact spot, blew away the sand and revealed part of the find.

The experience came to life in two different contexts. Locally, a roadshow with several stops made the display case accessible all around the city. Online, through the campaign’s website, you could blow away the sand from anywhere in the world, seeing the live streaming video of the robot moving and unveiling the find.

The installation was running on a ROS system, Arduino Mega, using blow sensors and controller, and an iPad to allow interaction with the visitors of the museum.

If you are a fan of cosplay, props and hand built creations you can’t miss the work of  James Bruton. Based in Uk he’s got a personal project YouTube channel with a new video every week describing his work in details. At the end of June he posted the 34th “episode” of the project started nearly a year ago about  building an Iron Man Hulkbuster giant suit you can actually wear!

In the video below you can follow how he’s sorting out the arm mechatronics for the elbow, hand and cuff weapon with some 3D printing with Lulzbot and controlling the interaction with  Arduino Uno (electronic part starting around minute 10):

Make your first wearable with Arduino Gemma

gemma_mindfulnj

Like the LilyPad Arduino boards, the Arduino Gemma is designed to create interactive projects you can wear. It can be sewn into clothing and other fabric with conductive thread and be connected to sensors and actuators.

After you explored the Getting Started page and learn how to move the first steps with it, it’s time to explore its features with a real project.

Becky Stern from Adafruit recently created a tutorial for making a vibrating mindfulness bracelet and learn the basics of wearables with Gemma! It’s like that “stand up every hour” feature you find on smart watches, but DIY.

The guide shows you how to solder up the circuit using an Arduino Gemma microcontroller, small pager motor, as well as how to whip up a cute linked leather bracelet to hold everything.

Build yourself a buzzing bracelet for subtle haptic feedback as time passes! It’s great for reminding yourself to get up and walk away from your desk for a few minutes each hour, or just as a way to have a new awareness of how the perception of passing time varies based on what you’re doing.

You’ll whip up a vibrating motor circuit using a transistor, resistor, and diode, and use GEMMA to control the frequency of vibration in between low-power microcontroller naps. The circuit lives inside a linked leather/rubber bracelet, but you could build it into whatever you please. This project involves some precision soldering, but is otherwise quite easy!

Read the bill of materials, follow the steps and create your Buzzing Mindfulness Bracelet on Adafruit.

Last month Massimo Banzi gave a lecture at the Computer History Museum in Mountain View (California, US). It was titled The Arduino Experience and covered the historical origins of Arduino, including a explanation of the process of designing tools which make digital technology accessible to people who are not experts, and the essential role of the larger Arduino ecosystem that supports it. After the keynote Len Shustek, chairman of the board of the Museum, curated a session of Q&A. If you didn’t have the chance to be there, the recorded video is online and you can watch it now:
