Ray Wang has been experimenting with the ESP8266 Serial-to-WiFi module, which has gained much hype recently. “The module is very compact, easy to interface with, and inexpensive. I wrote an Arduino program to show how to use the Arduino to communicate with the WiFi module and set up a very simple web server.” Check out the blog post at RaysHobby.

I’m in the very early stages of prototyping a nixie clock. I picked up some MJE340 power transistors to switch on some IN-3s. I can then use a digital pin on my Arduino to turn on the IN-3s through the transistor. I’ll then have myself a blinking colon for my nixie tube clock.

The Arduino and Cloud-based homebrewing controller by Martin Kennedy of TheBedroomLaboratory:
It’s just a basic site, based on this Scotch.io tutorial, which is currently plotting the temperature in my sitting room. It’s got a PHP backend (Laravel framework with RESTful API), MySQL database and an AngularJS frontend with (n3-chart/d3 for the graph). In the house, I’ve whacked together a quick breadboard circuit which comprises of an Arduino clone, a DS18B20 Temperature Sensor (with resistor for the i2c connection) and an ESP8266 module. Every minute, this wireless sensor POSTs the temperature to our REST API. This value is saved in the database and will appear in the graph whenever the page is opened. To hook it up to a fermenter, the sensor would just be placed in a thermowell in the fermenter bucket so we can see the beer temperature over time.

It’s Like a Shield for your Shields! Makes debugging your Arduino projects super fast! by Guido Bonelli Jr @ kickstarter.com:
Do you love Arduino development BUT dread testing your hardware because there is no easy way to attach things like your meter, oscilloscope or probes?
Well fear not, ArduinoNaut, Dr.Duino™ is here to the rescue!

Arduino, known for creating an easy-to-use microcontroller revolution, is about to launch its own 3D printer.
The Arduino Materia 101 made its global debut earlier today on the official Arduino twitter account with a photo of a boxy white and teal FDM printer and a note that Arduino co-founder Massimo Banzi is showing the printer live on Italian TV. It also states that the printer will be presented next weekend at Maker Faire Rome.
In the image, the printer appears to have an LCD screen, a control knob, and a switch on the front plate. A filament spool holder with a matching color scheme sits attached to the right side. The mechanical bits are obscured, so details about its extruder or print bed size aren’t clear, but we’ll be looking forward to learning more shortly.

Microduino-Joypad is … an 8-bit game console + open source + UPin27 + AVR,STM32,MSP430,51 compatible + smart controller == Awesome! by Microduino Studio:
Microduino studio launched the first kickstarter in September 2013, introducing the brand new Arduino-compatible development board—Microduino. We achieved success with the unique Upin27 interface, compact size, rich expansion boards as well as many applications. Over the past year, Microduino community has been growing rapidly. Now we have nearly 10,000 players worldwide.
At the 25th anniversary of the Gameboy console, we are now releasing Joypad – 8-bit multi-functional game console to show our respects to Gameboy–the most classic game console in the history.
With this elegantly designed little Joypad, we are hoping to bring you the greatest joy from your childhood memory. The best thing is it’s completely open source and you can even create and develop your own game to inspire your imagination. Moreover, it’s not only a game console, it’s also a remote controller for other devices, such as Quadcopter, robot and cell phone, etc.

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v projects. The Maxim DS1339 however, features a wide tolerance of voltages from 2.97V-5.5V with the typical voltage as 3.3v, a battery backup, two alarms, and a trickle charger. The breakout board here packages the DS1339 with the components and connections necessary to use with your Arduino projects easily.

You may be familiar with a website in the UK called Colour Clock (http://thecolourclock.co.uk/) which converts the time into a hex value and then uses that value to update the background color. It’s very hypnotic and once you get used to how it works you can actually tell where you are in the day just by glancing at the screen from across the room.
I had an Arduino Uno R3 and an Adafruit 1.8″ Color TFT Shield w/microSD and Joystick that I was trying to use for another project that kept stalling out. One night just for fun I decided to see if I could recreate the Colour Clock and it only took a couple hours. If you’re familiar with Arduino you could easily swap parts out for a simple TFT breakout board and something tiny like a Beetle and make a very compact unit. You could even wear it as a badge.

Arduino hacked Ericsson T65 mobile phone GSM remote control. By Konstantinos Kokoras @ youtube.com:
Accepting incoming call from predifined caller and after 2 rings hungs up and turns on a device through a relay.
Also accepting incoming SMS’s from predifined caller and depending from text tuns on or off a device through a relay.
After each command execution it sends back a confirmation SMS.
Unfortunately Ericsson T65 has only PDU mode for SMS.

A recent press release from Atmel has announced the introduction of the Arduino WiFi Shield 101 which can be connected to any modern Arduino R3 board to give connectivity to the Internet via any traditional Wi-Fi access points. This new Shield is said to offer secure, cost-effective, high-performance Wi-Fi connectivity. The new board is targeted at Arduino IoT applications and incorporates Atmel’s WINC 1500 wireless network controller offering IEEE 802.11 b/g/n (1×1) at up to 72 Mbps and supporting IEEE 802.11 WEP, WPA2 security enterprise.
