CLK2A - Divisions

Introducing the new CLK2A Division module. This is the first of a range of CLK Clocking modules - yes, it does seem strange to start with CLK2A but that's because CLK1 will be some form of 'Master' VC-Clock and there should be a CLK2B with binary divisions.

This show-cases two new setups:
  1. The Clocking 'Bus' - internal connections are made between CLK Clocking modules allowing 'Master' controls of Clock and Reset (eg. with CLK1 VC-Clock as Master)
  2. SMD (Surface Mount) construction - in a bid to make designs easier to fabricate many parts are being moved to surface mount and thus eliminating hand-wiring. New banana sockets now securely fix the front-panel to the two parallel-mounted PCBs and the result is an incredibly compact module. (this also, for now at least, rules out the possibility of mini-jack modules -- a whole new PCB footprint would be required)
[Not shown in the images above: - one IC has vanished from the 2nd picture (?!!) and mounting pillars are not fitted to join the PCBs together -- these are initial Proto pics!]

CMOS Modulars

The 4000 series CMOS logic series holds some wonderful chips for clocking (ie rhythmic) and audio generation (squarewaves). There's a very inspiring new forum at electro-music.com that's dedicated to / inspired by Stanley Lunetta..
Lunettas - circuits inspired by Stanley Lunetta

Here's my first module - clocking and XNORs - pretty much the heart of a Weevil but without body contact and power starvation..
Quite a few more designs in the pipeline now - the rhythmic possibilities are really exciting.
I'll be posting more details such as panel layouts and schematics shortly. The whole idea behind these circuits is that they're meant to be quick and dirty -- its actually the panel making that seems to take the longest!

Edit:: more schematics and details now on my electronics page
