Here are some pictures of a frequency counter i contructed entirely on breadboard and some day i hope to rebuild it on some real PC board. Schematics will be coming eventually.
Here is the function generator measuring the waveform seen on the handheld scope you can see that the measurement is just as accurate s the meter.
Here is the power supply now that i have a dual power supply built I no longer will need to have one on bread board.

And here is the whole mess sprawled across my workbench.
