A poorman’s oscilloscope
The result summarized on this web page is a fully functional (memory)scope that samples the analogue input signal and subsequently displays it on a normal TV. Unfortunately the µSCOPE works only on 625 line PAL standard TVs, and It was never the intention to build a sophisticated measurement instrument. Nevertheless, signals up to a few kHz are reasonably well displayed by this simple circuit that can be build for only a few euro.
