Bringing makers back to the Lab
Scientists working in a lab are just folks. Like motor heads with cars, we have our favourite makes and models—except with scientists, it's all about the lab equipment.

Smart Remote Control Doubles as Super Simple IR Sniffer
Want to sniff a remote control or other IR device's control codes? The Smart Remote Control will make quick work of that, combining an Arduino Yún with a simple solderless breadboard circuit.
A simple light follower with Analog 180° Micro Servo
Servos are composed of an electric motor mechanically linked to a potentiometer and they are able to translate the width of the pulse into a position. When you command the servo to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.
Today we’d like to share with you a tutorial with the aim of showing how to make a simple light follower made of cardboard using Arduino Uno and a microservo, in this case the Analog 180° Micro Servo.
Follow the step by step lesson to build one yourself.
Arduino sensors let ballerinas 'paint' with their pointes
What if you could paint with your shoes? Electronic Traces is a pair ballet pointe shoes that sends a dancer's movements to a nearby smartphone. Using Lilypad Arduinos, they record pressure and movement whenever they touch the ground. This data can then be visualized by an accompanying app, allowing dancers to view their performances after the fact, or compare them to others'.

MOMA Adds Arduino, Makey Makey, And More
I've always said that one day I'd wake up and the Arduino would be in a museum. However, I'd sort of expected it to take a bit longer. 
Medical Tricorder Mark I
A handheld tricorder is as good a reason as any to start a project. The science-fiction-derived form factor provides an opportunity to work on a lot of different areas of hardware development like portable power, charging, communications between sensor and microcontroller. And of course you need a user interface so that the values being returned will have some meaning for the user.
[Marcus B] has done a great job with all of this in his first version of a medical tricorder. The current design hosts two sensors, one measures skin temperature using infrared, the other is a pulse sensor.
For us it’s not the number of sensors that makes something a “tricorder” but the ability of the device to use those sensors to make a diagnosis (or to give the user enough hints to come to their own conclusion). [Marcus] shares similar views and with that in mind has designed in a real-time clock and an SD card slot. These can be used to log sensor data over time which may then be able to suggest ailments based on a known set of common diagnosis parameters.
Looking at the image above you may be wondering which chip is the microcontroller. This build is actually a shield for an Arduino hiding underneath.
There’s a demonstration video after the break. And if you find this impressive you won’t want to miss the Open Source Science Tricorder which is one of the finalists for the 2014 Hackaday Prize.

The KIM-1 Computer Minified
The KIM-1 wasn’t the firs microcomputer available to computer hobbyists and other electron aficionados, but it was the first one that was cheap. It was also exceedingly simple, with just a 6502 CPU, a little more than 1k of RAM, 2k of ROM, a hexadecimal keypad and a few seven-segment displays. Still, a lot of software was written for this machine, and one of these boards can be found in every computer history museum.
[Oscar] thought the KIM-1 was far too cool to be relegated to the history books so he made his own. It’s not a direct copy – this one uses an Arduino for the brains, only breaking out some buttons, a pair of four-digit seven-segment displays, and the I2C and SPI pins on the ‘duino. The KIM-1 is emulated by the Arduino, allowing for the same interface as an original connected up to an old teletype, and [Oscar] got his hands on the original code for Microchess and the first 6502 disassembler from [Woz] and [Baum].
[Oscar] put the schematics for his version of the KIM-1 up, and has the PCBs up on SeeedStudio. If you’re looking for an awesome replica of a vintage computer and a nice weekend project, here ‘ya go.

MoMa welcomes Arduino
We are really happy to share with you that at the beginning of the week Paola Antonelli (Senior Curator Department of Architecture and Design) and Michelle Millar Fisher, (Curatorial Assistant, Department of Architecture and Design) published on the Moma blog a post announcing the acquisition of Arduino and other DIY electronic devices in the collection of the Museum of Modern Art of New York City, with this explanation:
As design curators, we have an instinctive response to designs we find compelling, and when that feeling survives the passing of time, we know we’re on to something worthwhile. We believe our new acquisitions will withstand that test. All promise to make a difference—not just in the utopian “design can save the world” kind of way (always good, but often a high bar for any one object), but at the very micro level. We all know what it feels like to master a skill previously thought completely outside our abilities, or to unlock new possibilities of experience and thought. It’s exhilarating, life-changing, and (healthily) addictive, the same reason people keep coming back to see MoMA’s Pollocks and Picassos—and, we hope, this new group of humble masterpieces.
That’s how they are describing Arduino:
A tiny but powerful microcontroller, the Arduino is an open-source, programmable microchip housed on a circuit board that fits in the palm of one’s hand—an apt metaphor for the control over design functions that it allows its user—and a pillar of contemporary maker culture and practice. Designed by a star-studded team, the Arduino can be programmed to drive components such as sensors, LEDs, and motors in order to build and develop all kinds of interactive objects. This new building block of design has resulted in applications as diverse as light sculptures, digital pollution detectors, and tools to help people who are unable to use such common interfaces as a computer mouse. Beyond its concrete applications, the Arduino acts as a platform for the interdisciplinary practice that lies at the heart of so much compelling contemporary work across science and the humanities.
NYC MoMA adds five maker devices to its permanent collection
If you've ever been to a Maker Faire, you know its as much of an art show as a technology showcase. Builders debut everything from robotic bands to educational circuitry kits at these events, and the NYC Museum of Modern Art is about to immortalize five maker products into its permanent collection. Early next year, the Arduino, Ototo, Makey Makey, Colour Chaser and a DIY Gamer Kit will be on display in the MoMA's design galleries, serving as representatives of the maker culture to the museum's visitors. MoMA is excited about the new additions, but it's not the first time technology has found its way into the museum's collection: in 2011 both Botanicalls and Little Bits found its way into MoMA's galleries. Check out the announcement at the source link below.

E-Traces: Ballet Slippers That Make Drawings From The Dancer’s Movements
