Digital Analog Power Junction

Human Beings are helped or hampered by many types of Microbes. From the Sub-Microbe virus to animal like Bacterium and plant like Fungi.

An Affordable Portable Electronic Microbe Detector using Mass Spectrometry; may be very useful for Small HealthCare Centers and Homes. If a Person Breathes into an adapter in the instrument, it should show a simple analysis of the Air Microbe Levels. It can also be used for CleanRoom Air Purity Indication.



This is just an idea for an urgent need, this may prevent spread of flu to escalate into an epidemic; due to early detection of microbe, at the root, in every home.

Here are some Mass Spectrometry Resources that students can study and attempt to research to Develop a cost-effective consumer flu-detection device.

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.

The DLM2000 is a bench-top oscilloscope for electronic design or debug.  It's ergonomic and easy to use, and packed with features. (product has upgraded to DLM3000)

DLM2000 Series Digital Oscilloscopes Yokogawa

The flexible MSO input lets you measure both, including mixed signal triggers and decoding of parallel or serial bit patterns.



Using logic input, up to 11 input signals can be observed simultaneously as 3 ch of analog and 8-bit logic. It is not only possible to use logic input for observation of data and control signals, or as a trigger source, but also for logic

The product range of Yokogawa include digital oscilloscopes, energy/power analyzers, data acquisition systems and Optical Instruments like Optical Spectrum Analyzers and Optical Reflectometer.

E-flite Mini Pulse XT - Brushless ESC Waveform

This waveform shows the square waves that drives one of the three phases at a relatively low throttle setting (coming from the brushless speed controller). The peak amplitude is constant for all speeds.

"Much more than just a self-serving video of my new R/C airplane flight agility, this model represents a plethora of modern electronics. Although the radio control system in this plane is a standard narrow band FM variety on 72.170 MHz (as opposed to my 2.4 GHz, spread spectrum system), the motor is a state-of-the-art 3-phase brushless model (E-flite 450)with a sensorless electronic speed control (E-flite EFLA331, 20 A)."
