MEET THE ARDUINO KILLER: ESP8266

Wi-Fi is an essential bit of kit for any Internet of Things (IoT) DIY projects, but our favorite Arduino doesn’t come with Wi-Fi, and adding in a Wi-Fi shield can bring the total cost to around $40. What if I told you a there’s an Arduino-compatible dev board with built-in Wi-Fi for less than $10? Well, there is. Meet the Arduino Killer: ESP8266. It was only a matter of time before the crown was stolen from the shiny head of our dear Arduino development board. Is it possible to fall in love with a circuit board? Catchy names aside, the ESP8266 (also known as NodeMCU) was originally marketed as a   Read More…

THE FUTURE OF DELIVERY DRONES

The Skynet concept offers a solution to the problems posed by drone delivery Image Gallery (8 images)  With drone technology progressing so quickly, it may not be too long before they start dropping packages at our doorsteps. But proposals for how the vehicles can safely navigate fences, pets and small children haven’t been entirely convincing so far. A pair of Australians believe they have the answer, with a system that sees drones zero in to drop deliveries into a purpose-built net, guided by LEDs to ensure centimeter-perfect accuracy. The Skynet concept won’t attract the publicity of big name announcements like those of Amazon and Google, but it may help shape   Read More…

.NET 2015 – .NET AS OPEN SOURCE, .NET ON MAC AND LINUX, AND VISUAL STUDIO COMMUNITY

It’s happening. It’s the reason that a lot of us work with Microsoft technologies, and I think it’s both the end of an era but also the beginning of amazing things to come. Here’s what’s happening and Microsoft announced it today in New York. There’s a lot here, Microsoft is serious about open source and cross platform. .NET Core 5 is the modern, componentized framework that ships via NuGet. That means you can ship a private version of the .NET Core Framework with your app. Other apps’ versions can’t change your app’s behavior. Microsoft building a .NET Core CLR for Windows, Mac and Linux and it will be both open source and it will   Read More…

THE RASPBERRY PI MODEL A+ IS SMALLER, THINNER, AND JUST $20

The Raspberry Pi Foundation released a new model of the Raspberry Pi. Dubbed the A+, this one’s just $20, has more GPIO, a Micro SD slot, and is a lot smaller than the previous model. Like the Model A, this one still just has 256 MB of RAM and no Ethernet port, but it’s now just 65mm in length and manages to consume less power. The new model comes packed with 40 pins on the GPIO, a Micro SD slot, and a new audio output with a low-noise power supply for better quality. Even better, this one’s just $20. You can snag one from MCM in the US today, and   Read More…

CANNOT GET MOTOROLA MC3190 TO ASSOCIATE WITH WIFI ACCESS POINT ?

Using the Wireless Fusion management tools for the Symbol / Motorola MC3190, we cannot get the handheld to associate to the WiFi access point. Using the Find WLANs feature in the Fusion software, we can see that the device is detecting the access point, as it does show up in the list of detected WLANs. So since it can see the available WLANs, the radio / hardware is seemingly working just fine. The access point is using WPA2 AES for security and other devices have no problem associating to it. It is a non-Enterprise level access point, so the Security Mode selected in the Fusion WLAN profile is “WPA2 –   Read More…

PLASTC, THE ALL-IN-ONE CARD THAT COULD REPLACE YOUR WALLET

  You already keep an array of cards in your wallet: Debit card, credit card and gift cards. Several developers are working on reducing all those cards to just one. Last year, it was Coin, the super card that holds eight cards and allows you to swipe between them at will. But Coin is still only available for pre-order. And now Coin’s worst nightmare has arrived in the form of Plastc, which promises to outdo Coin in every way. For starters, Plastc holds more cards: 20, to be exact, interchangeable via the card’s E-ink display. It also has upgradable firmware, allowing for new features as the technology develops. Plastc comes   Read More…

COMBINING RFID AND DRONE PLATFORM COULD SAVE MILLIONS OF DOLLARS

Inventory tracking across large open yards presents a serious challenge to many traders and distributors in the world, resulting in higher operational costs To address this challenge, a application can be developed to accumulated RFID tag signal data via an RFID reader mounted on their customized UAV. This would then be transmitted in flight, in real-time, back to their bespoke inventory management system using a GPRS connection. The inventory system then processes the RFID data and accurately determines the location of the individual bundles to within 2 square meters 98.2% of the time. locations are then updated by inventory system and graphically available on a map overlay to Yard managers, as   Read More…
