The Freeky Wobulator kit is a mid level kit that features a bare board Arduino shield for the ATMega 328P chip driving a direct digital synthesis (DDS) module containing AD9850 chip. A Nokia LCD display provides the user interface. The functions are all menu-driven and frequencies, modes, sweep rates are simply selected using the 6 push button interface You can’t break this device by pushing the wrong buttons! The kit is supplied with sockets for the ATMega and modules

I was experimenting with the DDS9850 board and it led to this creation.

It has two Frequencies A & B and can sweep between, over time, or by a control voltage, or front panel knob. Its a useful test function generator for experimenters from 1 Hz to 40+ Mhz.
