The holiday season is supposed to be a happy time. But lets be honest, between the stress of picking out gifts, racking up credit card debt you can't afford and being forced to spend time with your creepy uncle there isn't a lot to smile about. Enter the JöLLY Tracker. It's a wearable of a different kind -- one that monitors just how much you smile. And, if you're not keeping that frown turned upside down, it gives you a gentle "reminder" to smile in the form of an electric shock... to the face.

The post Arduino Announces New IoT Board, Gives Away 1,000 appeared first on Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers.

It’s a great pleasure to introduce the new member of the Arduino and Genuino family: MKR1000 is a powerful board that combines the functionality of the Zero and the connectivity of the Wi-Fi Shield.

It’s based on the Atmel ATSAMW25 that is part of the SmartConnect family of Atmel Wireless devices, specifically designed for IoT. It offers the ideal solution for makers seeking to add Wi-Fi connectivity with minimal previous experience in networking.

The new board will be available for purchase from February 2016 but starting today #1000 MKR1000 can be won in the World’s Largest Arduino Maker Challenge in collaboration with Hackster.IO and Microsoft.

We want to celebrate the maker community so we thought there’s no better way to do that than encourage inventors, artists, makers, hobbyists or professionals and developers to create on Arduino. The contest is very flexible – choose anything you want to build from environmental sensors to gaming, augmented reality, robotics or UAVs using the power of Arduino.cc boards and Windows 10.

The 1,000 makers who submit the best project ideas will receive the newly released Arduino MKR1000 (US only) and Genuino MKR1000 (Outside US) boards. Then three finalists submitting the best completed projects will be awarded with a fully-funded trip to Maker Faire Shenzhen, New York or Rome; a chance to present their creation at the Microsoft and the Arduino and Genuino booths; a professional video production of the project; and a whopping $500 gift certificate to Adafruit.

Contest starts today,  December 9th 2015, when participants can sign up or log into Hackster and enter to win the new MKR1000 board by pitching the idea. Idea submissions close on January 15, 2016 at 11:59 PM (PT).

If you watch much science fiction, you know that in the future, there’re plenty of 3D holographic displays. From Princess Leah’s distress call to the Star Trek holodeck, there’s no shortage of computers that can make realistic images. It might not be up to holodeck standards, but [freedscript] created a 3D display for an Arduino using a chopstick, a motor, some paper, and a LASER. Of course, it isn’t actually a hologram, but neither is half the stuff you see on TV (Star Trek’s holographic characters were disturbingly solid for standing waves). The display is a type of volumetric display.

The idea is deceptively simple. A paper corkscrew spins and a laser spot perpendicular to the axis of rotation can create a point that appears to be anywhere in a slice of the volume enclosed by the outer perimeter of the corkscrew. You can see in the video below that the device is simple to build, although the results are not overwhelming. If the corkscrew is too big, the edges will have to move too fast. Also, you need a lot of LASERS, including one to sense the index point of the corkscrew.

Still, it is impressive to see an Arduino driving a 3D display, and the system is simple enough to hack if you’d like to experiment. We’ve looked at other optios for 3D displays before, both using lasers and using computer projectors. Maybe Princess Leah’s distress call will soon be a reality.

A picture might be worth a thousand words, but for an interactive sound work called GRIDI a picture is worth infinite midi loops!

The post You Can’t Touch This! Arduino Yún Alarm System appeared first on Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers.

It’s no secret that hackers like to measure things. Good numbers lead to good decisions, like when to kick your wastrel teenager out of a luxuriously lengthy shower. Hence the creation of this wireless Arduino-based water meter interface.

We’ll stipulate that “wireless” is a bit of a stretch. Creator [David Schneider] chose to split the system into two parts – a magnetometer and an Arduino to sense impulses from the water company meter, and a Raspberry Pi to serve the web interface. The water meter is at the street rather than in his house, so the sensor is wired to the Pi with some telephone cable. But from there the system is wireless.

[David] goes into some good detail on the sensing problem he faced, which relies on detecting the varying magnetic field due to the spinny-bits inside the flowmeter and cleaning up the signal with the Arduino; he also addresses aliasing errors that occur when flow rate approaches the sampling rate of the magnetometer.

We like the fact that there’s a lot of potential to leverage this technique to monitor other processes with rotating magnetic fields. And like this optically coupled gas-meter monitor, it’s not invasive of the utility’s equipment either, which is a plus.
