Whether you’re lodged in an apartment with a poor view of the sky like [Becky Stern] or are looking for an at-a-glance report of the current weather, you might consider this minimalist weather display instead of checking your computer or your phone every time you’re headed out the door.

The first order of business was to set up her Feather Huzzah ESP8266 module. [Becky] started with a blink test to ensure it was working properly. Once that was out of the way, she moved on to installing a few libraries. Temperature data fetched by an IFTTT feed is displayed on a seven-segment display, while additional feeds separately retrieve information for each basic weather type: sunny, overcast, rain, snow.

All it took to create the sleek display effect was a few pieces of cardboard inside a shadow box frame, a sheet of paper as a diffuser, and twelve Neopixel RGB LEDs hidden inside. Trimming and securing everything in place as well as notching out the back of the frame for the power cable finished the assembly. Check out the build video after the break.

Pair this weather frame with a shoe rack that spotlights the appropriate footwear depending on the weather to really streamline your exit.

Screen Shot 2015-12-04 at 1.45.57 PMThe purpose is clear. You don’t want your kids to steal your food from the cupboard, or from the fridge, or someone to open your locker. Or maybe you want to take pictures of your pet stealing food. Or maybe you are Dwight Schrute and you want to finally unmask […]

Build an IoT Gauge with Arduino Yún and IFTTT

Tomas Amberg shared with us the link to an Instructable he published on how to build a Web-enabled, Arduino-based IoT Gauge with a REST API, and connect it to the IFTTT mash-up platform, via the Yaler.net relay service he founded.

The cool thing about this project is the connection with the Maker Channel  of IFTTT which supports custom Webhooks, to integrate DIY IoT projects: 

Inspired by WhereDial, a DIY Internet of Things classic, the IoT Gauge shows the current location of its owner. A bit like the Weasley Clock in Harry Potter. The design and code of the IoT Gauge is generic and could be used as well to display e.g. weather conditions. The logic resides in the Cloud, the gauge is just a servo with an API.

Check out the five-step tutorial and the ingredients you need at this link.

Better than an Xbee and cheaper Hobby King 433Mhz Radio Telemetry Kit 100mW

IFTTT, YouTube Commenti disabilitati su Better than an Xbee and cheaper Hobby King 433Mhz Radio Telemetry Kit 100mW 

Ran this wee puppy at 57,600 full duplex no issues at 1/4 mile with the RX inside my neighbors brick post box. Seems to penetrate the masonry better than a 2.4Ghz Xbee and its half to a quarter of the price the price especially if you buy from Sparkfun. 

Like the Xbee it resumes comms very quickly after a power cycle which is pretty essential for RC usage. 

Arduino Xbee Receiver Arduino Nano V3.0 Microcontroller Board from hobby king



Features:
• Very small size
• Light weight (under 4 grams without antenna)
• Receiver sensitivity to -121 dBm
• Transmit power up to 20dBm (100mW)
• Transparent serial link
• Air data rates up to 250kbps
• Range of approx 1 mile
• MAVLink protocol framing and status reporting
• Frequency hopping spread spectrum (FHSS)
• Adaptive time division multiplexing (TDM)
• Support for LBT and AFA
• Configurable duty cycle
• Built in error correcting code (can correct up to 25% data bit errors)
• Demonstrated range of several kilometers with a small omni antenna
• Can be used with a bi-directional amplifier for even more range
• Open source firmware
• AT commands for radio configuration
• RT commands for remote radio configuration
• Adaptive flow control when used with APM
• Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller

A quick test at 57,600 Baud seems like a great product and well priced at US$29.99






XBee Pro 60mW Wire Antenna - Series 1 (802.15.4) 

US$37.95 AND YOU NEED 2



FPV 433Mhz Radio Telemetry Kit 100mW
US$29.99 AND YOU GET A PAIR





An interesting price point comparison between Sparkfun and HobbyKing on another useful and in this case identical product. HK are almost 80% cheaper





Arduino 9DOF ArduIMU Controller ATmega328 (ACCEL/MAG/GYRO)

 US$29.99




Same product from Sparkfun 9 Degrees of Freedom - Razor IMU 

US$124.95



So HK sell this identical device for almost 80% less

But it get worse if are a Kiwi you buy from our local Sparkfun reseller





9 Degrees of Freedom - Razor IMU - AHRS compatible NZ$180.49


To be fair on Mind Kits they do buy from Sparkfun but that said the bloke at Mind Kits has a way worse supply deal then Hobby King
