I am looking for some very good projects for master's degree in VLSI design.Can anyone suggest?
I keep seeing this qn so often from grads of VLSI design ...VLSI design is such a big ocean, unless you tell me what course work you did and what your skillset is , its really hard to say. 1. Analog IC design : Just do a bandgap reference design or design a ECG sensor 2. Digital IC : Tell me whether it CMOS or ASIC or FPGA. Try Home :: OpenCores for some ideas...Design a architecture for ECG or EMG sensors. Write RTL for the same. Do the simulations. Search Internet of Things on google and build the hardware part of it...3. VLSI Manf : Try doing some yield characterization or DFT or IC Testing ..Much of this can be done only through univ-industry partnerships or if you get an internship at TSMC or UMC etc...4. VLSI CAD : Develop a simple router or clock tree implementation algorithm which does asymetric skew balancing and/or reduce buffer count etc...5. VLSI systems design : For extra kicks, implement a whole architecture like circuit, embedded micro controller programming like ARM CortexM3 etc...design a smart meter, program the microcontroller, read data from it, find the energy trends and send email alerts...Use Arduino/Raspberry pi to test and build prototypes....There are many interdisciplinary VLSI areas but really out of scope of the answer now and I can talk on each of them for whole day :) ... Good luck...
What are some sensor based embedded system projects that can be implemented in real life?
Basically you are looking for the real time embedded system sensors projects that are useful in day to day life.Though i am not a person belonging to this field of technical expertise. But if some sensory system that can be made to determine the fatigue rate of a driver via eye blink.Or sensory system to conserve the energy in one form and that can be further used into other. Solar energy consumption and combined with some sesory processor that detects if this useful energy can be used to drive motors , fan, light at home.Or sensory automation that can be utilized for women security , by embedding it with some app and genral features added to it. Any intelligent sensory automated system integrated with a smart phone app.These are just ideas, i am not sure of the complexity or the practical implementation. So if found vague then please ignore.. :)
Finding a Sensitive Hall Effect sensor or equivalent?
I just had a "Doh!!"-moment when I tried using a A1302 hall effect sensor and basically got a DC signal at a very steady 4.7V. Looking at the specs I see this thing is never going to directly pick up anything at 1 or 2 mV per Gauss (the earth's B field is typically on the order or 1/3 a gauss) by itself. For applications where I want to resolve 1/10 gauss on my oscilloscope how can I get this done? Is there any way to make this work using a simple op amp circuit? What would be more sensitive commonly available Hall effect sensor or equivalent IC, and where would I get one?
How do I learn the algorithm when doing an Arduino project without looking up existing projects online?
A really nice question (even I myself had the same thing on my mind a few months back)1. To make something fly stably:You really need to learn and understand control theory!The astounding athletic power of quadcopters - see this video! This one served as an inspiration to me. Depending on the type of drone you are making, you have to mathematically model it first. And using the sensor data from the drone, implement a PID controller or any other control methods to stabilize the system.2. Building from scratch:Building it physically won't take much of your time, but coding it from scratch will really take a lot of time! You need to perform several trials and then fix your tuned PID constants.3. Algorithm:Regarding the programming! Try to learn about state machine design and also try to code efficiently. Assuming that you will be using Arduino Uno you'll have to use many libraries to interface with sensor modules and storage modules which is going to increase the weight of your program!4. All the best ! :)
I'm in need of SS49E, a linear hall effect sensor for flux measurement in my final year project. It is not easily available. Where shall I find it?
You can always look for alternative sensors. Instead you can use Winson wsh49e linear hall effect sensor which looks like a direct replacement for Honeywells SS49E. Check wsh49e datasheet and compare the sensors. You can also use wsh315 Linear Hall effect sensor as well.
How can I get large datasets collected from sensors? For example thermo dataset like (temperature, humidity, wind speed, etc)!
I suggest you start at a page such as this List of citizen science projects or Where can I find large datasets open to the public, and look through them for open data sets around topics which require sensors, such as monitoring of air, water, or light pollution, or other ambient conditions. (Of course, you'll be disregarding a tremendous amount of wildlife counts, transit ridership, or crime rate reporting if they're not relevant to you.) The governments of the world and citizen science projects produce large amounts of open data. I imagine some academic efforts also produce and publish open data, and the trend is growing. If you have a particular topic or measurement in mind, search for "open data" or "open dataset" and the topic or measurement of interest. If you're looking for sensor-generated data in particular, here are some topics you might explore, with a such a search: climate/weather, pollution, seismic activity, solar intensity, pollen count, traffic speeds, usage of electricity or water.
How can I build a color sensor without using microcontroller?
Of course you could use something more complex than a micro controller like a raspberry Pi with the camera module, but I don’t think that’s what you were thinking of.You can infer colour from tone using something as simple a light dependent resistor. I managed to make a Lego brick sorter using early mindstorms kit that only had a very basic light level sensor. This only really works when you know what the colours are going to be.If a non digital solution is what your looking for, colour sensors that don’t require a digital interface are available. You could get one that outputs voltage for example and then interpret the output using a number of comparators, or frequency output and a number of filters. This information could then be used to light an indicator for example in the colour your trying to detect.Color Sensors | DigiKey
What are the types of sensors used in underground water detection?
For a project of this type, you would be looking to use Sonar or Ultrasonic Sensors. One particular recommendation that I have if you are looking for this type of sensors is BTIC. They specialize in the development of advanced sonars and underwater acoustic systems.I am not affiliated with them, but have worked together on projects with them in the past.
