Nice junk-yard find! (PIC)

so my dad-in-law brought back a big box of junk from the scrap heap, I dug through it and pulled out this:

oh, and top-left is a Nixie tube - never saw one of those I.R.L. - they look so cool without them glowing! You can see all the lovely art-deco numbering all lined up inside :-)

you'll be right for switches for a while then! :hihi:
If there were sliders, that panel would be almost perfect ready built for a Klee.
What's on the underside of it?

check it out, it's 32 switches AND 32 LEDs, all wired neatly to a board with DIL headers - it's PERFECT for a sequencer project!

I figure a long row, but split into 4 independent 8-step gate sequencers.... nice, right? If you look at the lower right it even has a start/stop setup!

Those rotary counters are fucking awesome! I love those kind of read outs. Those and the old-school alarm clocks, where the numbers flip down. :party:

Does it have the circuitry in tact? It may already be able to be used as a pattern generator as is!

they're actually a fancy kind of 0-7 switches - like big-ass funky-looking digital switches - each of the 6 numbers in each case has 4 lugs; input and 3 outputs, so a binary readout, should be perfect for a lot of the weird stuff I mess with on the protoboard, hehe.

no, the circuitry has been surgically removed - we found it, I think; a nice wire-wrapped board with 4 sockets named "4017a" through -d - it definitely used to be a counter unit of some sort - and it shall be again!

It'll be dead-easy to interface with; LEDs already have resistors mounted, everything is in place - I just need to un-bend a few pins on the connectors and I 'm off :)

yeah, I'm leaning towards a gate/trigger sequencer - it could comfortably be split into 4 8-step sequences, side-by-side :deadbanana:

Will try to snap a pic of the inside, it's wonderfully done, sort of semi-diy, in that B&K have some of the best techs this side of Hamburg ;-)

*drool*
That's a beautiful front panel... It would make for a great gate sequencer. Can't wait to see what you come up with.
I've always thought that Nixie tubes and modular synths would go well together. At a chemistry lab where I used to work, we actually used a pH meter that had five or six small-ish Nixies as its display. They're amazing to look at when turned off, and even more-so when powered up.

Looks like Boba Fett's enjoying hanging out with those electronics parts. :nana:

- interesting... even when there's 32 steps?

It sure would take a lot of the "oh balls, now I have to wire all THAT?" out of a Klee...

the trick would be to design a panel components pcb
which would connect to the klee pcbs by pin connectors / ribbon cable

if i didnt have a circular sequencer design i may have done this

If that thing was bult for a bunch of 4017s I'd re-use it for that, doesn't the klee deserve a dedicated UI?

I read an article on getting 19 steps from 2 4017s on EDN the other day, I didn't realize you can clock those guys from the + & - edge of clocks! This has had me playing with a bunch of ideas. A counter that outputs two pulses for each clock! :drunkhomer:

I did a double-take when I saw that panel. The company I work for still produces a XPDR/DME test set that uses thumbwheel switches, believe it or not. The panel looks vaguely similar to your lucky find.

We used to produce a discrete ARINC bus breakout box - sadly it was discontinued a few years back. I say 'sadly' because it was so cool looking in an extreme synth-geek way. Finding a discarded panel for one of them would be a banana-jackers dream come true. Here's a pic of it:

I got those same switches in my Sphere 900 equalisers.
It seems these are VERY expensive when new. (hundreds of dollars each)
good find!
Cheers!

Another way:

but I think the trick with getting two counts from one clock via the clock enable pin is pretty neat.

or maybe;

SOOOO many good ideas!

I'll definitely use the slick plasticky encoder-panels for something neat - perhaps as some sort of logic-toggles.
