Yeah, as I say, more details (schematic!) shortly - reckon over the weekend I'll have some time....
The switches are just SPDT centre off ---> the Up position ties the control input to V+, the mid position (ie no connection on the switch) makes the control low due to a 100k pull down resistor, and the Down position connects the external input socket.
The board is mini - just a little bit of stripboard with a few resistors and jumpers. So quick and easy to build! If you see the screw in the centre, near the bottom - that's affixing a mounting post which holds a home made little metal 90degree angle which holds on the stripboard. Yeah, I'll do a pic and you'll see how simple it is behind!
Yeah, and I do make my own banana cables - its really quick and easy (no soldering) - I tend to make 'em in batches and can make 60 in 60 minutes or so. That's a LOT quicker than you could do for 1/4" or 1/8" cables! Loads quicker, loads cheaper - hmmm, gotta love those bananas! _________________ http://www.bugbrand.co.uk

Ok, I got a bit of updating done (though its maybe still a bit sketchy...)
Just put details of a few things up on my electronics page:
http://bugbrand.co.uk/pages/electronics.htm
Including schems and front panel files
Here's the schem for the 4089 implementation::
Having investigated the outputs a little more, I figured why I was getting confused --- at audio rates you do hear the output as binary divisions (octaves) (and this can be great because you can turn off/on each sub-octave!), but at lower freqs you realise that things are a bit different to other binary dividers because of only getting a Hi pulse for one clock pulse (ie 1/16th of the sequence).. Umm, that's already sounding gobble-di-gooky!
-- basically, each division fits its pulse(s) within the spaces of the other divisions --- hmm, there's a pic on the datasheet
I don't know how to describe this! _________________ http://www.bugbrand.co.uk

YIPEEE~~~~!!!!!
this is exactly what i have been messing around with this week so i am so glad to get these schematics! great panel designs too. you are a serious diy guru.
i made a module this week where i took a big stripboard, and stuck a 4070, a 4020, and a 4040 all on the damn thing and then put every pin out to a jack. its on a 3wide frak panel and its so full of jacks!! but its been great! _________________ -------------------------------------------- check out various dan music at: http://www.myspace.com/lossnyc
