Becky Stern writes, "Send your valentine a note through the net! This DIY electronics project uses a small vibrating motor to gently wave a tissue paper heart and flash an LED when it receives instructions over the internet from another device. I built two versions of the ESP8266 wifi circuit, also equipped with two buttons for triggering the two commands. The devices talk over the Adafruit IO cloud data service to communicate with each other from anywhere with wifi, and I'll show you how to activate your valentine with the API gateway service IFTTT as well, in case you only want to build one valentine circuit."

Trossen Robotics challenged the roboticists whom it serves to make junkbots out of grab-bags of surplus parts they had lying around. The three winners are extremely impressive! Read the rest
Julian Oliver is a playful and media-savvy security researcher; previously, he documented hidden cell-phone towers in bad disguises and produced a hand-grenade shaped "transparency device" that spied on everything going on in the room. Read the rest
The Elegoo UNO Project Super Starter Kit comes with a bunch of different components, including sensors, a servo motor, a stepper motor, a joystick, a breadboard, and lots more. Most of the reviewers say that the Elegoo UNO is a good Arduino Uno clone. The one thing people have complained about is the tutorials. They say they are poorly written. That's not a problem because there are lots of great Arduino books, and I have a video class on getting started with Arduino on Skillshare that is highly rated. At $32, the components alone are worth the price. Read the rest
Kyle writes, "The Volt is a fully open source, arduino-based, handmade analog clock that tells time with meters. Available in a DIY install kit, 2 pre-made models, and a mix & match hardware option. The clocks are but with solid black walnut and maple, with faceplates produced in brass, copper, and steel. Only on Kickstarter!" Read the rest
Arduino is an electronics prototyping platform that gives non-engineers the ability to add interactivity to their projects. (I teach an online Arduino course on Skillshare that 1,163 have taken with a 97% rating).
Amazon has a sale on the genuine Arduino Starter Kit for $72. It has the Arduino Uno microprocessor and a bunch of components, along with instructions for 15 projects that will give you a feel for all the things you can do with Arduino. Read the rest

Researchers at the ETH Game Technology Center of the Swiss national technical institute in Zürich, have applied their considerable talents to the critical problem of immersion in 2D side-scrolling, 8-bit era games. Witness in this video the splendor of a 360° projected Mario world that unrolls across the walls as players reveal each subsequent tile of the game map.
Robert Sumner, founder of the GTC explains:
...we observed that the 8-bit era of gaming had a huge collective influence on so many people, but the actual gaming experience was typically an individual one. We wanted to turn this idea upside down, and elevate the NES console experience into a group experience where the game surrounds a large event, allowing multiple people to play in a collaborative setting. The panoramic stitching and 8-way controller multiplexing hardware were the main ways we accomplished this task.
The group submitted the paper "Unfolding the 8-bit Era" to the European Conference on Visual Media Production, and then built the system to unveil at the Eurographics Conference. Utilizing a vintage 8-bit Famicom/NES system and a PC with a point-correspondence vision tracking algorithm, the researchers developed methods to detect the edge of each screen segment, adding it to a continuously expanding texture map in real-time. This panoramic texture is then seamlessly displayed on eight aligned projectors. The vision algorithm requires no prior knowledge about the game, so it is possible to play any side-scroller on this system, such as Super Mario Bros., Castlevania, Metroid, and the like.

Alan Turing and the codebreakers of Bletchley Park invented modern crypto and computers in the course of breaking Enigma ciphers, the codes that Axis powers created with repurposed Enigma Machines -- sophisticated (for the day) encryption tools invented for the banking industry -- to keep the Allies from listening in on their communications.

747 people have taken my online Introduction to Arduino course on Skillshare, and the class has a 95% positive review rating. The entire video course runs a bit less than an hour, and I explain what Arduino is, what you need to use it, how to get started, and how to build some simple projects. No knowledge of programming, engineering, or electronics is necessary. The class focuses on hardware to get you using the board right away.

"This is my first foray in the world of interactivity," says Grady Hillhouse. "It's an arcade-style puzzle box mini game. Powered by an Arduino with completely custom wooden enclosure and components, the goal was to make it look like something your parents told you not to play with when you were a kid. The object of the game is to adjust the knobs so each needle points at its respective LED, but it's not as easy as it sounds (or is it!?)." [via]
