Vortex lets kids program their own robotic toy

Atmel | Bits & Pieces

Vortex is a smart and responsive robot that kids can play with and program themselves. 

The emergence of robotic gadgets have inspired a new generation of toys that are not only fun but educational as well. Joining the likes of Sphero, Hackaball, Kibo, LocoRobo and several others, Shanghai-based startup DFRobot has introduced a smart and responsive device for kids. Named Vortexthe robot enables its young users to play various games, learn about programming and even create their own via an accompanying app.


Designed with the novice Maker community in mind, Vortex works right of the box and simply pairs to a smartphone (iOS and Android) over Bluetooth. Thanks to its built-in computer and a dozen sensors, it is capable of maneuvering around the floor, desk or table with a touch of the screen. Vortex features four pre-installed, multi-player games, which allow kids to compete against one another in sumo-like bumping fights, play a round of virtual golf, race throughout the house or partake in an immersive match of robot soccer.

While Vortex will certainly prove to be an…

Part Search Engines – semiconductors, chips, mcus, 부품검색, 가격비교

아이디어만 있으면 부품 제조까지 참 폄리한 세상니네요 ㅋ

Internet Life

컴퓨터, 가전제품, 휴대폰 등 우리는 제품을 사기 위해서 많은 사이트를 비교하고, 최저가를 찾기 위해 노력한다.

하드웨어 설계자들이 회로를 구성하고 시스템을 만들기 위해 쓰이는 부품들도 이런 과정을 통해서 경쟁력 있는 가격에 구매를 하고 싶은데, 가능할까? 일반 소비재 처럼 구매자가 일반적이지 않기 때문에 일반적인 가격 비교 사이트에서는 찾아 볼 수 없다. 물론 중국의 알리바바는 모든 것이 있다고 하니 찾을 수 있을 듯 하다. 그래도 한 번 찾아보자.

구글 검색을 하니 떡 하니 많이 방문하던 Adafruit 에서 관련 글을 하나 찾을 수 있었다. 원본글은 다음과 같다.

In general, we use findchips.com and then back that up with octopart but whichever you use they’re pretty similar in functionality. We think that if you’re good with component naming conventions, findchips is a little more powerful – you can search and compare multiple packages/tempgrades. If you’re just starting and images help you out, octopart has that going for it.

Introducing the SmartConnect SAM W25 module for edge nodes IoT applications

SmartConnet SAM W25 is a Atmel WiFi module with standalone MCU

Atmel | Bits & Pieces

Now on display at Electronica 2014, the SmartConnect SAM W25 module is the industry’s first fully-integrated FCC-certified Wi-Fi module with a standalone MCU and hardware security from a single source. The module includes Atmel’s recently-announced 2.4GHz IEEE 802.11 b/g/n Wi-Fi WINC1500, along with an Atmel | SMART SAM D21 ARM Cortex M0+-based MCU and Atmel’s ATECC108A optimized CryptoAuthentication engine with ultra-secure hardware-based key storage for secure connectivity.


With nearly 5 billion connected devices expected next year with another 25 billion predicted by 2020, designers are now demanding more flexible, cost-optimized modules that provide a complete end-point solution from a single vendor. The fully-integrated SAM W25 delivers a secure ‘plug and play’ solution integrating wireless technologies with the design flexibility required for these IoT developers.

The billions of devices in edge nodes IoT applications will be powered by an embedded processing unit such as an MCU, and connected through a secure…
