[sdiy] din clock variable shuffle

[gregory zifcak]

oops, i just found this in the archives, duh. funny, it must have worked its 
way into my mind when i wasn't paying attention, and jumped out now when i 
was trying to puzzle this out another way. sounds excellent, anyone want to 
suggest a vc clock schematic and a divide by 6 chip?
