UV916-tuner Radio Receiver 45-860MHz To build a Spectrum analyzer I needed a tuner. I also needed to learn how to control the tuner. In some old broken TV I found the tuner UV916. It is a common used tuner. The tuner is PLL synthesized controlled and the frequency can be set from 80-900MHz. The tuner [...]
Notes In this circuit, the 7815 regulatates the positive supply, and the 7915 regulates the negative supply. The transformer should have a primary rating of 240/220 volts for europe, or 120 volts for North America. The centre tapped secondary coil should be rated about 18 volts at 1 amp or higher,allowing for losses in the [...]
Build your own a cheap simple Microcontroller learning board S-52. The board is based on ATMEL’s new ISP chip AT89S51, AT89S52, or AT89S53. This board can be used by beginners for learning Assembly and C language programming. Single sided PCB file included. Introduction I have designed this leaning board to be used as a tool [...]
