LEDs used in Outdoor Digital Sign Boards
Hi - I recently got a project of designing an 'Outdoor' digital sign boards that can display color pictures etc. I know that the LEDs that are used in outdoor digital sign boards are not regular LEDs. They are very high power LEDs (or LED bulbs) that one...
embedded systems +job +market
Hi,
I am doing my Masters in Electrical Engineering (from US). Right now I have 2 options, either to do major in networking or in embedded systems.
I want know that whats the job market of embedded systems in US. What field would be better for me if i wanna work...
tems ericsson documents
Tems is a special phone desiged to investigate cellular network (like GSM or WCDMA). Parameters like call success rate, drop call rate, handovers, link quality and many more can be tested. I have manuals of Tems from sony ericson. If u want them, plz reply
Hi
I am working on a project of RF power meter (wattmeter) that can measure power of signal having frequency upto 900Mhz. I want to know that is there any IC (or circuit) available that can measure high frequency power (upto 900Mhz) and give output.
Thanks
microcontroller c51
start by making a project of Pulse generator of different frequencies. It is the basic that will be used in most of the projects. Then generate pulses by timers.......after that use timmer interepts for generating pulses. After learning the basics move towards projects like...
Sure it is possible to connect an I/O device to the 8086 CPU without PIC. U need buffers (like 74245) and latches (like 74373). U dont essentially need to use the interrupt vector table unless u have a HUGE task to perform. Simple IN and OUT instructions can be used to move data from I/O devices
USB microcontroller
hi
there are a no. of microcontroller that have USB port. Especially most of the newly introduced micros have buildin USB port. If u wanna use a micro-controller with USB, first of all look that which microcontroller u have worked previously (like Atmel, pic etc) then search...
avr versus arm what is the better
ARM micros are the best.....If u have a choice to choose between ARM and AVR and u want to do any ONE of them, then i suggest u to learn ARM. ARM micros can be used for big/complex projects and it can do every thing (as far as i know) that AVR micros can do but...
resistance evaluation
Such type of resistor is used as a jumper but be carefull abt the current rating. Every resistor has a certain range of current that it can handle....
how to make PCBs ?
Make the PCB design on the computer. Take the printout of the MIRROR image of PCB u have designed on the Press-n-peel sheet. Put the press-n-peel sheet on the the board and then hot iron (5 min approx) on the press-n-peel sheet. After that remove the press-n-peel sheet...
u have to go through a lot of books for getting some command over analog circuit design..start with simple networks consisting if Resistors and capacitors...then move forward to network consisting of diodes, transistors etc..i suggest "Engineering Circuit Analysis" by WILLIAM HYATT a nice book.
