After listening to what everyone said about my first one, and looking at what you all came up with, here's my latest one. Another chain in the chinese whisper. Hand drawn and then heavily filtered.

just want to contribute something, so here is my slightly different approach (obviously it has nothing to do with paul klee but it follows the organic route):

scribbled just a little bit more...

here we have a expressPCB footprint with real thru holes. on a probably manufactured PCB it could look like this:

I really like this one too. It seems to sum up a lot of the ideas which have been bouncing around, but draws them back towards a more recognisable font. Well done Photon!

[Uncle Krunkus]

In fact I like it so much I had to tweak it!
It's a blatant rip off of Photon's, with squashed EEs and freehand through hole effect.

I like the last one, but it isn't abstract enough for me. I would think flipping the K around the vertical axis would make the design more abstract and more symetrical.

Hi,

As some of you know; I've been working for a few weeks now on a Scott Stites approved version of the Klee. Based somewhat on the older version and this thread, it's a little thing I've been calling the Mini-Klee.

It's natively made to fit the Frac/Euro Format; and is pretty cool at 6" wide. It is designed to both supplement and interact with the K2 as described in this thread. I asked Scott how soon the PCB's might be available for the K2 and he was unsure;

EDIT: PCB's are in the works and now announced by Scott and Andrew. See related thread!
so I need to build one of the K2's to go with my Mini using the Uncle Krunkus stripboard layouts so I can ensure that they play well together!

I've been waiting on parts to populate a set of the Krunkus boards. Some of those arrived with today's mail pickup so I began the task of checking out the K2 schematic and layouts more completely. Since the Mini-Klee uses different shift registers and methods for selecting and recirculation; I haven't had need to consider the schematic for the K2 Stage encoder until now.

And I think there is a problem with EDIT: No, it's just you, Randal.

Hope this is useful and accurate. Please let me know if the latter is not!

EDIT: It wasn't and you have been, Randal

BTW, The mini is not designed to replace the Klee; it is a complement that does things the K2 does not and likewise the Super-Klee does things the Mini does not. The Mini provides a full Klee experience in a smaller space.

Accessory modules were designed for the mini which will work with both versions of the Klee; and are based on Emails with Scott about additions to and needs of the K2; and also on comments and ideas expressed in this thread.

These add-ons include the SLO (Sample Lag Oscillator: an LFO geared specifically to Klee needs and providing some useful outboard processing.) The MOD (Modulation inputs and CV processing), and the G-ABL (Gatebus Analog Boolean Logic module) This adds Gatebus logic options, pattern storage and retrieval, and a couple other items I'll announce in a new thread.

Scott is right; these Klee's are fun!

EDIT: At least you have this part right, Randal!

Hey Randal,

Thanks for checking - it always helps to have another set of eyes.

The schematic is correct. The breadboarded prototype is wired as per the schematic, and works as described.

Take for example the 8X2 Pattern Mode. In this mode, both switches are closed, which puts the A, B and C selection pins at ground (low).

When A is low, pin 14 is connected to pin 12. When B is low, pin 15 is connected to pin 2. Bit 8 of Register A goes into pin 2, passes out of pin 15, enters pin 12, and exits pin 14 to feed the serial in of Register A. Thus, you have recirculation of the data around Register A.

When Pin 9 is low, pin 4 is connected to pin 5. Bit 8 of Register B enters pin 5, exits pin 4 and enters the serial input of Register B. Thus you have recirculation of data around Register B. Recirculation of both registers = 8X2 Pattern Mode.

Another example would be the 16X2 mode:

SW1 is low, so A is low. Switch two is high, so B and C are high.

Therefore, pin 14 is connected to pin 12.
Pin 15 is connected to pin 1.
Pin 4 is connected to pin 3.

Bit 8 of Register B goes into pin 1 and exits ouf of pin 15. It then goes through pin 12, out pin 14 and into the input of shift register A.

Meanwhile, bit 8 of Register A enters pin 3 and exits pin 4, which feeds the serial input of Register B. Thus, bit 8 of Register B feeds the input of Register A, and bit 8 of Register A feeds the input of Register B, forming a recirculating 16 bit shift register.

Using those examples, take another look at how the other modes work.

Scott,

Thank you.

I found my error. I am(WAS! ) using a transcribed truth table for the 4053. I have two; much dog-eared databooks on the 4000 series chips. Unfortunately each has a different layout to the truth table. I've been using one at work and one at home. One has abc xyz columns; the other is cba zyx.

I know they're different; but got caught in seeing what I was "used to" seeing in one book; whilst looking at the other during the transcription..
So my transcribed truth, isn't.

Thank you again; sorry for the bandwidth.

Like Steve Ciarcia says; solder IS the best programming language!
(or in your case, spring clips )

It is hard to find two data sheets that jibe on the terminology of the CD405X pinouts. My data sheet, the CMOS Cookbook, and Express schematic all call them slightly different things. And I couldn't lay out that section of the schematic more confusedly if I tried. I should have broken it up into its three sections, which would have made it a bit clearer.

Cheerios,
Scott

Cant wait! =D
Another thanks for all the hard work.

So...has anyone taken a pass a a front panel for this? In any format?
21 pots, 17 jacks, 22 LEDs, and 43 (!) switches... the front side is going to be a busy place. I'm not sure I can grok it yet.

click!

[Randaleem]

Hi Mike!

see Fonik's page and site for Klee info. Here's a link to his early panel design:

http://www.klee2.fonik.de/#Panel13


As mentioned in another thread: I am working on several versions of the EM Klee front panel (all the popular formats, and desktop unit) which I will post next week.

[Scott Stites]

I fired up the Klee breadboard today for the first time in several weeks. Man, once you get that magic combination of pot settings going, it's almost better than sex. I'm nowhere close to maxing out on this thing - I can't wait to have it behind a panel.

Anyway, I had this idea of a patch that hadn't occured to me before - it was during a conversation with Randal that it struck me.

It's quite possible to chain the shift registers of two electro-music Klee Sequencers together without any modification to the Klee or the panel. For those of you who are planning on more than one Klee Sequencer, or are considering Randal's Mini-Klee, this ought to be very interesting.

The patch works by simply setting one of the gate bus merge switches on and patching that bus's gate output to the random input of the second Klee, and then connecting the second Klee up to the first in the same manner. Now you have two gate busses sharing a pattern of up to 32 bits, with six unique voltage patterns derived from this pattern. Even more interesting, you can alter the length of the shift register by selecting which stage is selected for the gate bus that's providing the loop signal - on both Klees. The permutations drive me mad to even consider it.

(Ron Popeil voice) But wait...there's more! This same patch is very useful even if one only has a single electro-music Klee Sequencer - in this case, you patch the afore-mentioned gate bus output into the random input of the same electro-music Klee Sequencer. This allows some very interesting changes to occur in a pattern. I'll write it up in the manual.

Cheers,
Scott

Does this mean that once these PCB's are distributed and assembled that they will become self aware a la Terminator 2? I can see it now:
All our base are belong to Klee!

[Scott Stites]

I sometimes wonder if the one I have here is self-aware.

Here's another couple of apps for all the soon-to-be Klee-ites:

The electro-music Klee can also function in a one-shot mode. In other words, if you send it a pulse to its load input, it can generate a single repetition of whatever is programmed into it. This, I suppose, would be sort of like a burst generator. Say you've got it set up in a patch in conjuction with another Klee, or sequencer, or divider, or random generator, or just a button with your finger on it (it could even be the manual load switch). At certain times, when you want to hear that series of notes, or generate that series of pulses, or whatever your Klee is bent on doing, the load pulse will trigger it to load up and shoot its wad.

It's done simply by putting it in the random mode and syncing it to some clock, but with no signal applied to its random input. The Klee will cycle the pattern off into oblivion and will generate nothing out of gate bus 1, gate bus 3, and the voltage outputs - no pattern is cycling. As soon as it gets that load pulse, it loads it pattern and slides that off into oblivion, generating however many steps are programmed into it in the process. In fact, if it's in the 8X2 mode, it can still generate either an 8 note (or 16 note with invert B on) repeating pattern with Register B, and generate an up to 8 note burst with register A when the load pulse is detected.

Note that above, no mention is made of Gate Bus 2. Gate Bus 2 goes into a special state when no pattern is present and the Klee is receiving clock pulses. If you recall your days of nodding off during Klee 101, Gate Bus 2 is derived by NORing Gate Bus 1 and Gate Bus 3 - if either of those two busses generates a gate, Gate Bus 2 remains silent. Well, with no pattern present, neither of those gate busses produce a gate, so Gate Bus 2 will generate a constant stream of gates and triggers in sync with the clock, regardless of the gate bus switch settings.

This leads us to special application number 2: Gate Bus 2 can be used to generate intervals of "silence" within a patch. Let's say you have the Klee with no pattern loaded and you're clocking, say, a sequencer, from the output of Gate Bus 2. When a pulse goes to the load input of the Klee, the pattern that is loaded can be used to "blank" the clock signal for a specific number of steps (up to 16). Moreover, the pattern can be set up so that the clock is not blanked, but attains some different sequence of timing during those 16 steps - a pause here or there, etc. At that time, Busses 1 and 3 could be set to do some other task in time with that event. In fact, it could be set to alternately clock something else, then generate its burst, then clock something else (ad nauseum).

I'll write it up (this is going to be a long apps guide).

Cheerios,
Scott
