  • Shaping waveforms gets turntable in a spin

    What is Gadget Freak about, if not the creative reuse of existing components? Thanks to Bernard Green, of Syemon Electronic Solutions, for sending in his ingenious self-built solution to a problem.

    He writes that he had a need to generate a single cycle of a very low frequency near sign wave, which was to be used to test software that measured the parameters of a waveform generated by a sensor.

    Several ideas occurred to him - using digital devices and a digital to analogue convertor - but these needed analogue filters with some big capacitors, which were absent from his 'junk box'. Then he had a brainwave...
