It's a little bit of everything really. It started off with me wanting to play with one of the PIC processors (18F4550) to do something useful but really to learn how to use them. Then I thought that I really needed a frequency counter (the board I posted is the log- amplifier and prescalar part so that I can get up to 500MHz). Then I thought about adding a frequency source and found the AD9958 DDS frequency synthesizer. By adding in the AD8302 IC I can get amplitude and phase difference values from a bridge. The PIC device as a USB port built-in and so would provide a nice controller for the whole thing - an LCD display and a few buttons for instantaneous or other 'in the field' use, with the USB receiving commands and sending back data for frequency-sweep analyses etc.. At night, when the thoughts run wild, would like to add a digital scope part as well but that will need its own ADC and memory to get the bandwidth up to something above a few MHz. Underneath it all, I was looking to fill in my time after my home circumstances changed an I found myself on my own. I returned to my old interests of ham radio and electronics and I was wanting something real to build, but would also be a real challenge and allow me to learn lots of stuff on the way. I think I might have got a bit carried away, but I'm having fun.
