Very Happy
It works , hooray (after sorting some silly mistakes on my part).
The pattern switches i initially thought made an "on" when switched to ground but it's really an open circuit is "on" & ground = "off".
All a good learning proccess Smile .

A very satisfying project from start to finish, very happy customer !.

Here are some pics of the construction......

You never showed a picture of the panel wiring completed LOL.

It's supposed to look like a plate of spaghetti.

Looking forward to hearing what you do with it!

About a week of evenings & a weekend to strip / crimp / solder the looms together .
Used a crodless drill to twist the wire looms together then snip off length needed.

Klee hooked up to 3 MFOS VCO's / 3 VCF's / 3 VCA's . externally clocked from a MFOS 16 step sequencer. with a CGS psycho lfo patched to the external range input & MFOS S&H patched to load in & MFOS Grainy noise to the random in switching the external ins on and off during the sequence No FX (dry as a pharaohs sandal) .
this mp3 just a patch up & try some switches as it runs .

Dave, very nice work man. Looks great and I am sure some great music will be made with it. I can't wait to hear it. Cool

A drill with "crod" can reek havoc with a project. This is the secret to success and should get me one to. Laughing Laughing

(Sorry ... he he)

Seriously, NICE !!!!!

You rock! Very Happy
Seems like a lot of work, 5 evenings and a weekend. But the result is great Smile
So you twisted the wires first, and then soldered the crimps to it? Did you use stranded wire?

Yes , stranded wire , should have used 16/0.2 wire for the crimps but i had a few drums of 7/0.2 to use up , tinning them first got a good hold for the crimp then tin after crimping to secure them....

Nice Dave! Good technique there. I don't use a crimp tool now. Do you recommend to use one? Are they expensive?

I got my crimper from Rapid uk , i think it was about £20.00, it's done well to do this & the complete ASM-2 crimping as well and you can change the crimp teeth as well .

What Model/Make is that crimper tool there Dave? I have been soldering my wires to the crimp terminals but just thinking I should start "crimping" the wires, then tinning as you do. Probably a better method really.

On another note, the one thing we probably should have added to the base design of the Klee is a VC controlled INTERNAL CLOCK. I see you added one to yours. Had you used the CD4046 PLL chip or another method? I am thinking about adding them as an option for my custom builds.

Hi Bill , i think it is Rapid's own brand crimper... http://www.rapidonline.com/sku/Tools-Fasteners-Production-Equipment/Hand-Tools/Tacking-Crimping/Crimping-tool-for-PCB-connectors/30535/85-0262


The internal clock i had success with a simple 555 clock circuit ( im sure it was an old Velleman kit timer diagram).

Dave.

Looks and sounds great!

Please tell me there's more supporting the pcb's than what's in the pictures.

One would be concerned at first glance but considering the size of the gear rack this is going into, I doubt Dave will be going out on the road with it. Thus, the lack of support under the boards. I am just guessing here. Very Happy

Personally, I use more supports since my racks are meant to be portable.

All my stuff is built for at-home use - I never take it out. However, I always build it sturdy enough for potential road work, just in case the next owner is so inclined. At least in my case, I probably won't be around forever, but I figure the stuff will end up with somebody - I'd prefer my legacy to be one of robust, working modules instead of busted, non-fixable pcb's. Just saying.

Having spent some time on the road, I've gotten to see road cases fall off loading docks. It happens all the time. In most cases, the road cases do what they're supposed to, and the gear survives. What I like to visualize is a road case falling off a dock, and the modular in the case hitting the ground sideways, and whether the pcb inside there is supported well enough so that all the connections will survive the fall. This is why I've stopped using pcb mounted pots - they never survive my visualizations.

Sorry for the rant!

Hey , that's cool , my fixings are sufficiant for my purpose , legacy wise ... theres no fun in obtaining a hand made modular , you really have to put the hours in to make it a personal machine, when i'm about to pop off , i'll order it to be destroyed Very Happy .

I played live ( 60 or so shows) in a Death metal band for 6 years in the early 90's and the assholes (the public) that purposely spill things or knock items over or stand on your ultra metal pedal has made me untrusting of a live audience . So no it will not leave the house , even if there's a fire ( great chance to re-design & make it better ) .

Very Happy
Dave

Congratulations on your completed Klee Sequencer. The demo was great, too!

I am currently designing my Klee panel... I really like your panel so I hope you don't mind if I borrow the design.

In order to fit my Aries synth, the panel must be 9" tall... I anticipate a 9 x 12 panel.

Hi Kevin

Klee is a really fun sequencer to use & build, I think it will integrate well with your impressive system.

You'll find the panel design in the post your klee panels Though i took a good handfull of influence from "sduck's" professional and cool looking Klee design when i started to think about my layout, Thanks sduck ( no hard feelings about pcb fixings, Wink ).

The skrog panel size is my standard 10" (250mm) high by 12" (300mm) to slip in where my soundlab used to be (soon to be soundlab ++ ).

Hope the project goes well for you Smile

Dave.

Thanks for the kind words! Although I think your panel looks a lot more "professional" (and cool!) than mine does!
