Bendable Color Epaper Display has Touch Input too

The Interactive Media Lab at Dresden Technical University has been busy working on ideas for user interfaces with wearable electronics, and presents a nice project, that any of us could reproduce, to create your very own wearable colour epaper display device. They even figured out a tidy way to add touch input as well. By sticking three linear resistive touch strips, which are effectively touch potentiometers, to a backing sheet and placing the latter directly behind the Plastic Logic Legio 2.1″ flexible electrophoretic display (EPD), a rudimentary touch interface was created. It does look like it needs a fair bit of force to be applied to the display, to be detectable at the touch strips, but it should be able to take it.

Looking at Things From a Different Angle

This robot inspects objects from different angles to classify them with a high degree of accuracy in real world scenarios.

Object recognition is a critical piece of many machine learning applications. Whether the goal is to create an autonomous car, a warehouse robot, or a package delivery drone, in each case, the devices must be capable of recognizing the objects that are around them. There are many proven models that classify a wide range of objects with a high degree of accuracy; however, these models do not always perform as expected under real world scenarios.

Print Infinitely-Long Parts on the New Infinity3D Belt 3D Printer

Belt 3D printers are just now starting to hit the market and Infinity3D is a new option with an extra trick up its sleeve.

Most 3D printers’ build volume is a function of their size. To get a bigger bed, you need longer X and Y axes rails. To print taller parts, you need longer Z axis rails. There are exceptions, such as SCARA robots equipped with extruders, but even those have limits. Belt printers are unique in that they can print parts of infinite lengths — at least in one axis. Such printers are just now starting to hit the market and Infinity3D is a new option with an extra trick up its sleeve.

Ubiquitous Energy tech turns any everyday glass surface into a solar cell

With the continuous creativity of humans, solar batteries have “escaped” from the familiar gray photovoltaic cells. With surprising ways of “transforming,” solar cells not only help to utilize the energy from nature, but they also have applicability and high aesthetic efficiency.

Now, a young California company Ubiquitous Energy has developed a “ClearView Power window” with transparent solar cells that selectively transmit light visible to the human eye while absorbing only the ultraviolet and infrared light and converting it into electricity. The company, which emerged from the Massachusetts Institute of Technology in 2012, hopes to use that technology to turn virtually any everyday glass surface into a solar cell.

Waterproof Sensors Designed for Submerged Wearable Applications

The flexible, waterproof design could be used for many applications, including wearable healthcare devices and scuba diving equipment.


Researchers from Soongsil University in Seoul have developed a flexible, waterproof sensor that can be used for submerged wearable applications, including scuba diving gear, healthcare devices, smart textiles, and more.

According to their recently published paper, the team demonstrated using the pressure sensor to control a phone, such as playing music and taking pictures, while fully immersed in water. They also incorporated the sensor into a flexible face mask, which could track the breath rate of a wearer by detecting air movement inside the mask.

Bay Area man uses 3D printer for good in hopes of restoring coral reefs impacted by climate change

OAKLAND, Calif. — A Bay Area design technologist is using 3D printing and calcium carbonate to help restore coral reefs and marine biodiversity that has been impacted by climate change.

Coral reefs are currently threatened by pollution, overfishing, and climate change.

According to SECORE International, fifty-percent of the world’s coral reefs have died in the past three decades. Ninety-percent of coral reefs could die within the next century.

Speak4Me is an eye-to-speech module designed to assist those unable to communicate verbally

People who suffer from physical disabilities that leave them unable to speak or communicate effectively can end up frustrated or largely ignored. In response to this issue, Hackaday users MalteMarco, and Tim R wanted to create a small device that can turn small eye movements into simple commands and phrases for easier communication, which they call the “Speak4Me.”

At the most basic level, the Speak4Me consists of an Arduino Nano board that controls a set of four infrared sensors which are pointed at the user’s eye within a single glass lens. Then once every 100 milliseconds, a measurement is taken to determine the location of the pupil and thus the direction being focused on. The word or phrase is chosen by first selecting a profile containing four groups of four elements each, for a total of sixteen possible combinations per profile. As an example, the caretaker profile has elements such as “yes,” “I want to sit,” and even “I need medical treatment.”
