Sine Wave Synthesizer
Posted on Tuesday, March 15, 2011   •   Category: Miscellaneous


Every group wants their final project to be something that will be remembered long after they're gone. Some do highly sophisticated and complex projects that entail upwards of a hundred hours to complete. Yet others go out of their way to develop something 'cool' and 'fun'. Luke and I decided that we wanted to be in this second category, because developing something that's 'cool' would also be fun to do. So in deciding what to design we tried to think of something that would catch the attention of the people in the lab. The easiest way of doing this is to create something that would make noise or play music so everyone in the lab could enjoy it. Realizing this would be the best way to go, we decided to create a synthesizer that could record and playback notes, 'teach' the user how to play a simple melody, and also play some prerecorded tunes. After all, don't you think being remembered as the group that played back the Imperial March theme from Star Wars is cooler than a paper tape reader? (no offense to those groups doing paper tape readers)

Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
