Hello everyone. I am a first year freshman in BE electronic engineering. We have a project to handle. The project is to build any electronic circuit of our choice. Better to make it on PCB. The project can be any circuit doing any work. Kindly suggest which circuits i can build. Circuit references will be apprecaited. Thanks in advance.

Er... You seem to be fresh on the internet as well. Ever heard about Google? Can be found on

CCD -> FPGA -> 100M-PHY .. for sub 100 USD in component costs ;)
Hi, Irfan. You've been in your classes -- you surely have some idea what you've been studying, and hopefully are starting to get an idea of what area of electronics engineering specifically interests you. The idea of the underclassman project in an EE program (sometimes done during Soph year) is primarily to give some experience in electronic construction techniques and hands-on experience rather than doing anything ground-breaking.
You might want to ask yourself what areas of your studies interest you. Or, if that fails you, talk with your adviser or an upperclassman. You could get info about some previous successful freshman projects to give you some ideas as to recommended circuit complexity, recommended writeup, and other requirements.
Your question is way too broad to give any kind of a helpful answer. You might want to post back when you've got something more to go on.
A couple of pieces of advice:
1) Hurry early. Work hard now to get a defined project, and get a start on purchase parts and the process of making a circuit board. Today. Make timelines with milestones. Check with your adviser to see if they're realistic. Stay on schedule.2) If you're looking at an existing design, make sure everything is still available before you commit. Parts do become obsolete.
3) If you're not familiar with any circuit board CAD software, and your school doesn't have a recommended package, it might be a good time to download the free Eagle layout editor:Make sure you know the restrictions of the free package.
4) Resist the temptation to just use a canned project with predesigned board. Take the time to learn the CAD software.5) As a Frosh, you probably don't have enough RF background to get yourself out of trouble, so stick with something slower-speed for a first project. Also, for the same reason, avoid home-brew switching power supplies for now.
6) Don't forget the presentation aspect. Your project will probably need a box or enclosure, and possibly an external power supply. Establish project constraints early, build around the constraints of the project, and get those items as soon as possible.7) Avoid biting off more than you can chew. Unless you're familiar with a particular microcontroller, don't make your grade here dependent on obtaining a development system and learning it. You will have to do this before you graduate, but underclassman project isn't supposed to be an enormous thing.
Have fun Chris
Irfan, I teach EE courses, and I run into this question a lot. Build something you want to have; build something that you will use. And, build something simple. If you are a freshman, you probably don't much circuit design experience. But you can get many projects right off of the internet. I have seen musician students build effects pedals for their guitars (surprisingly simple). One guy built a push-button siren to be used at basketball games (it wasn't loud enough). And one guy built a temperature activated fan. He would put this on his desk, and if it got warm, the fan would turn on. Anyway, there are thousands of useful circuits to build. Just pick one that you want to build.

Irfan, The demo version of Cadsoft's EAGLE *is* very usable but is has a limitation that you might find troublesome: maximum board size for their trialware is 80mm x 100mm. (The limits of 2 copper layers and 1-sheet schematics are less likely to be an issue--if you take Foley's advice to "stick with something slower-speed".)
Another package that is getting a lot of notice recently is KiCAD. It was started by some French academics and because it is open source software (gratis and libre), it doesn't have any purposely-crippled features.
Yup. Getting familiar with the mechanics of your CAD package will make life much easier. . . As others have said, *find something that interests YOU*.
How about a versatile graphics viewer? You could call it irfanview
How about a hand help pong game. Use the an up/dn binary counter(4029) and a 4 to 16 decoder(4514) to drive leds in the play field. Say 10 x 16 grid and then use a 4017 to randomly shift the row. You can have 16 push button switches at each end of the field that has to correspond to the ball and paddle. Implement s score counter etc. What you think, too hard / too simple ? JTT...
Thank you all of you for your great replies. I will be building an AM/FM/SW active antenna, and a simple FM transmitter and reciever. Great replies and great help from you people.
