Hello all,

I must admit I like the Simmons Analog ClapTrap Sound. (Also as demoed on Dubka's Simmons Clap Trap thread.)
There is some very nice stand alone device, which for me the PCB takes too much hp's in my Eurorack.

As for myself, and kind of 'per request' of
Dubka

I don't have the know-how or the schematics but that would be a great little module...

This is a great box, there should definitely be a clone done...someone help!

Great work, is this going to be available for sale as a kit or prebuilt unit

and so on... on this thread: https://www.muffwiggler.com/forum/viewtopic.php?t=82424

Given the above, I decided to build a 'clone' of the Simmons analog Clap Trap.
I will further refer to it as the Clap'a'Trap ('a' from analog).

I've been able to lay my hands on a bunch of NE566, so I can build quite some.

Humaniser has been built in, not copying any of the clone's circuit on the forums.
Auto and Humanizer leds are buffered not to draw 20 mA from a CMOS device.
Audio, Synth(trigger), Footsw and Out are ESD protected.
It's all on a single PCB, thus able to be put in an depth limited Eurorack.

I haven't decided yet whether I will sell the PCB with or without SMD (about 140 components). That will probably depend on the requests.

Current status:
Proto design is done and PCB has been ordered today.
FrontPanel is designed. (all comment welcome)

Given the other projects I'm running, I expect it to be available in about 8 weeks (exclusive summer holidays).
I will provide the FPD and Overlay design files, so you can decide whether it's a FrontPanelExpress panel or manufactured by e.g. Julian who was so kind to provide a FP for evaluation on the MP7 'fully loaded version'.

Pls feel free to start a request list.

All comments welcome.
As I'm on a businesstrip till june 8th, I can not reply very fast.

Interested and watching thumbs up

ohhh ace, I'm def in for one

The Minipops project was a bit large, and out of my price-range, unfortunately, but I'd definitely be up for one of these!

Wow! Claptrap season on MW?!

Definitely interested but my SMD skills are crap at the moment. Either way, exciting!

Not sure how useful it will be as modular given there is no trigger or CV inputs?
But it could fit nicely in my SDS-V

The synth input is the trigger input. That's how the Simmons one was labelled.

Is http://snw.lonningdal.no/ your site?
makhho
very much in it for one of these!

I'm in for one. Maybe two.

Interested in two

thumbs up snw. sub domain is short for my username yes

I will update that when I'm back home.
Thanks for informing me.

@Boogie Could you explain the purpose of the inputs?

YES!

interested SlayerBadger!

any estimations on price tag?

thx

There are three kinds of trigger inputs.
Synth to be renamed to Sync. this one uses an externally generated sync puls (Voltage to be applied)
FootSw is the next one and is a switch to GND
Then there's the audio input which triggers on external audio.
Indead there are no CV inputs.

As above.
Here's a nice demonstration of the function of the audio inputs. (starts at around 20 sec.)

No not yet.
Will depend on the number of interested people and mainly SMD populated or not.

For SMD population,
I discourage to use this project as a first trial for SMD soldering.
It's all 0603 (that would still be doable) but then there are multiple chips with a 0.65mm pitch meaning just some 0.3 mm isolation between the pins.

Hiya Boogie,

Looks great. I would love a PCB/panel set. Will you be creating a specific thread for that?

Thanks and hope all is well!

I would be interested in a PCB/panel. I'm pretty comfortable with 0603 parts so I wouldn't need a populated PCB.

Once debugged I'll calculate the costs and place the results in this thread.

Let's see where this thread leads to.
Anyhow, if the proto is OK, I might sell some unpopulated PCB's and provide a comp refdes printout. The density does not allow for well readable RefDes placement on the PCB.
If I have to run a next 5 pieces after initial debug, There will be some PCBs left for SMD population.
I a bunch of people would buy the thing, I will do a SMD populated PCB in addition.

And here's the first real FP by Julian

Great job done !

If it will sound as the FP looks like, it's going to be great Rasta-nana

right on!

As with the minipops - what do you think about an expanded version with more cv options for modulating the parameters? thumbs up
aragorn23
I'd be down for an unpopulated PCB and panel.

Let's do a poll and see where it goes.

I'll start a list to keep track of all requests.
