BJT project ideas for first-year engineering students

[Usama Khurram]

I need help in making my project using Bipolar junction transistor. I'm Engineering student (Ist year). Can someone here suggest me a Funtastic project that i can make easily and impress my teachers as well using BJT transistor. I have rea the Cascade, cascode and Darlington technique to amplify signals. Microphone to speaker, temperature sensors to alrm are the general projects i think. but i want to make some special... please help me out. thanks
