Light to Frequency Generator Update

Sometime ago I posted code and a schematic for the LTF Generator.  Well, here's the board for those interested!  Perhaps I'll upload a video, and attach a link for batchpcb should there be enough interest...As a recap, this unit takes data from two tls230r light to frequency converters, and uses an arduino to create simple syncopation, outputting on a standard headphone jack.

Although, if i get around to it, i may just pair it all down to the essentials: boot the arduino for an attiny, throw in a power amp, and reduce the size threefold.  I should do that right now.
