| jose347:
So you own a power supply, an oscilloscope and a function generator. Whats next? what are you suggestion for fun and simple projects to start the ball rolling? |
| jose347:
I'll start for the shy people, I think an oscillator is a cool and simple project to make, making an AC signal out of DC and be able to look at it from the oscilloscope is gratifying. |

Measure the resonant frequency and quality of a LC-tank circuit using the ring-down method: http://www.giangrandi.ch/electronics/ringdownq/ringdownq.shtml And's here's a video: |

If your generator is stable enough and can be micro-adjusted in frequency, you might try to find resonant frequency of a crystal. I did that with a rather large batch of crystals and was disappointed in how inaccurately they were marked. A crystal has two resonances, you hope, and they are very close in frequency. One is parallel and is sensitive to circuit loading. The other is series and is probably a better check. Many of the crystals I tested had multiple resonances, some dangerously close to marked frequency. They are probably products of sloppy manufacturing but since I never manufactured one I don't really know. |
