A sine wave generator that works by using a counter and using preprogrammed values for different steps of the sine function (Defined by the potential divider on the bottom, although it hasn't been fully tweaked yet) and some passive smoothing elements to make it a bit better on a small scale such as 3 bits of resolution.
The 555 Timer on the bottom is just to keep the peace because Everycircuits's sine wave element fixes the simulation speed, which I absolutely hate >:(
