FireFly WSN Platform

The main Firefly board uses an Atmel ATmega1281 8-bit micro-controller with 8KB of RAM and 128KB of ROM along with Chipcon’s CC2420 IEEE 802.15.4 standard-compliant radio transceiver for communication. The maximum packet size supported by 802.15.4 is 128 bytes and the maximum raw data rate is 250Kbps.

FireFly WSN Platform

FireFly Power Monitoring and Control Board  - In this project, we design and implement a remote switch control and power measurement system by using CMU Firefly wireless sensor board. The basic function for the system is that one central node can remotely switch on or off electronic devices and get the information, e.g. power, back from the switches. The basic design includes three parts: switch module, power measurement module and CMU Firefly board.



The demonstration shows that central node can wirelessly control the four lamps individually and the accurate power from each of the node is transmitted back instantaneously. The functions such as power-save and autoswitch pattern are also implemented. The power measurement ranges from 10W to 1000W, which is suitable for most industrial electrical system.

Internet and Intranet of Things - IoT

When Intelligent Devices (embedded systems) are privately and securely networked, it is called the Intranet of Things. This is like a Home-Office-Business private closed Cloud. This is ideal for Home and Infrastructure Automation and even Big Business or SMB Automation.

The Internet of Things - IoT is the Superset. It could be Secure and Private but still vulnerable to security lapses and breakdowns. This could send devices, robots and machines Berserk.

In all Networked Environments we have to have fallback arrangements when network fails or is compromised or even slow due to peak hour internet traffic.



WSN - Wireless Sensor Networks and M2M - Machine to Machine Data Communication;

M2M and WSN is a closed private Intranet network that is used in Manufacturing and Industrial Automation. Here we could use data sync to Interface it with the Web or Internet. This enables passive controls and monitoring of SCADA or Machine Status, yet very Secure.

COR - Collaborative Online Robotics - This is like team work for bots. Big tasks can be accomplished by very small and weak robots. Example - Observe Ants and Bees.

All these only mean Wireless Networked Intelligent Embedded Systems. They could be machines, appliance, robot or gadget. The brain is both on the device and in the Clouds.

BlackBoard - Circuit Layout.and Simulation

An Open Source "Learning EDA" Software which can setup circuit layouts. You may use it for stripboards, perfboards, breadboards, and even for plain circuitry or simulation. Creation and editing of symbols and elements on-the-fly using an integrated editor

BlackBoard - Circuit Layout.and Simulation

The Library has more than 300 different elements and symbols. Has an Integrated SPICE simulation support with netlist generator. NGSPICE Frontend (comes along with NGSPICE for Windows).

These are some of the Components in the Library. Makes Setting up a circuit layout fun.
