    Why do electrical engineering students have to study computer programming

    I think it depends which area of electrical engineering you want to concentrate on. Let's say that you are interested in solid state devices, then you might not ever use traditional HLLs like C or python, but you would definitely need good programming skills with mathematical software like...

    Are There Better Antennas for Tx433/RX433 RF Modules?

    HI, I am using tx433/Rx433 RF modules to transfer some data between two AVRs. I know that we have to use 30-35 cm simple wires as antennas. I send out out two bytes. The second byte is the actual data , and first byte is to get rid of unwanted information. However, I have a hard time...

    Troubleshooting DS18S20 and Atmega16: Data Pin Not Pulling Low

    Thank's a lot! Turns out I was using bottom view as top view and messed up Vcc and ground pins. It works fine now. I am surprised the chip didn't blow up.

    Troubleshooting DS18S20 and Atmega16: Data Pin Not Pulling Low

    Hi, I checked the resistor to make sure it was 4.7kohms. So, if Vdd pin is connected to 5v and ground pin to ground , the data pin (center pin) has voltage of ~5v ( after disconnecting the resistor). Does it mean the chip is bad?

    Troubleshooting DS18S20 and Atmega16: Data Pin Not Pulling Low

    Hi, I am trying to use digital temperature sensor DS18S20(http://datasheets.maxim-ic.com/en/ds/DS18S20.pdf) with Atmega16(http://www.atmel.com/dyn/resources/prod_documents/2466S.pdf). I am using it in a non-parasite mode i.e. Vdd is connected to external power source(Vcc) and Data pin is...

    Analog to digital conversion for a project

    This sounds interesting. So I am trying to use as few digital components as possible just as a challenge. Do you think it would work if I used R2R ladder http://en.wikipedia.org/wiki/File:R2r-ladder.png instead of DAC ( the problem I run in there is that apparently: "On a printed circuit...

    Analog to digital conversion for a project

    Hey guys, I am trying to do analog to digital conversion for a project. I don't want to use the digital chip, but want to do it in analog. I need 8-bit resolution. I found one approach: string resistor ladder. It uses 2^n-1 resistors. For 8-bit conversion I will have to use 255 resistors...

    Building a Quadcopter from Scratch - Tips & Resources

    I am planning to build a quadcopter from the scratch. I tried to do some research online, and am not happy with what I found. Everyone used Aurdino boards, and just connected the parts together. eg. http://aeroquad.com/ I want to build all electronic components myself like wireless FM...

    What's Next in Hybrid Analog/Digital Projects Beyond Ultrasonic Rangefinders?

    I am looking for suggestions for a hybrid analog/digital project. I have built an ultrasonic rangefinder before, and am now ready to tackle something more difficult and exciting. I found a lot of examples of such projects, but I am looking for something new and innovative.

    How Can I Land an EE/CE Internship and Develop Marketable Skills on a Budget?

    First of all you should identify a field of EE/CE that excites you. Are you looking for more computer engineering oriented internship where you will get to work on CPUs, graphics cards, FPGAs , etc. or are you looking for more electrical engineering side where you can do analog design, signal...

    Getting started in electronics for non-EEs? Basics?

    I would recommend https://www.amazon.com/dp/0867204826/?tag=pfamazon01-20. Its an excellent book to get hands-on experience with various experiments. The labs are exciting , and you will feel like you accomplished something by the time you go through it. It is used for intro phys lab courses in...
