Frequency Divider

Turns Gnome Into "Super-Gnome"



Here's the schematic for the frequency divider that I've been using with my Gnome.

This is a fairly straightforward approach and the diagram shows interconnection with points in the Gnome.

Make note of the 10K, .047 Low Pass on the output for a "mellow" sound.

The 50K level pot has to be a miniature type to fit in the Gnome case. The rotary switch is likewise miniature and has a small rubber grommet for a knob.

The only real challenge is getting everything to fit into the Gnome case. Mine ended up having the control about where the "Gnome" logo was on the case. Assembly was accomplished via perf board, wiring pencil and epoxy.

EDITOR'S NOTE;

Some of you may recognize John's name. He has published additional items on electronic music in other magazines.

When we were in San Francisco for the Computer Faire, John dropped by the booth and whipped his trusty Gnome out of his backpack. He showed me this nifty "divide by N" circuit which allows you to do pseudo-tracking VCO sounds.

The switch positions corresponding to "divide by 2, 4, and 8" will, of course, provide octaves below the original Gnome signal range. However, the "divide by 3, 5, 6 or 10" provides a really full bodied harmony which you somehow don't expect from a little Gnome.

This circuit is definitely worth the 5 bucks or so for the parts. Hopefully, we'll have more goodies from John in the future.
