Is the BOM for 12V or 15V operation? :)

Where can I find info on adding pitch control to this module?

Thanks

It works perfectly fine at either voltage!

hello stacy,

some trouble here (i'm newbee diyer), maybe you'll can help me to fix that ?
there's no action when i send a trig in trig/gate input. but :

it's seem the noise work good, but it's endless when i up the intens. (and level) knob. the noise a and noise b affect this noise. and the volume up correctly when i send a trig in the accent input.

like if an adsr doesn't work.
any idee, please ?

thanks

Hiya Maxime.

Sure, I can try and help but I have to admit it is quite difficult to solve any problems without seeing the boards in person!

Can you please check and double check for shorts on the back of the PCB? Sometimes even just a hair of a wire can short out stuff and make it not work. This happens to the best of us and is usually the cause of 90% of problems!

Also, please take a photograph of the front and back of the PCB for me (high resolution in sunlight so I can see properly), making sure I can see the part numbers on the components you used. If they are not legible, please tell me the exact part numbers you used for the ICs instead!

It is important that the CD4069 is "UB" suffix, NOT "B" suffix.

thanks stacy, all seem to work finally.
i just don't understand the clap have to receved trig + accent. i just send a trig on it.
is it right ? is it the same snare, kick, and rimshot ?

thanks

Hello Hex. Sorry if this has been asked but when will you be restocked?

Hey Maxime,

Hmm, no, you should be able to trigger the drum with just a trigger signal! They all work like that :) The accent is tied up so that by default it is as loud as possible, but if you plug in an accent signal, you can vary it yourself.

As a matter of fact, PCBs just arrived today! :) Go ahead and order!

I will have Jupiter Storm PCBs likely on Monday or Tuesday of next week if you want to wait -- there will be plenty of clap/snare PCBs in stock until then so there's no risk of them going out of stock if you choose to wait to bundle up and save on shipping.

Oh. Strange.
When i plug a jack into the acc (without any signal) everything work.
But if nothing is connected to the acc nothing work :(
I'll check and sent you a photograph tomorow.
Thanks for the infos ;)

Haha! And rimshots (with pitch mods), and 808 toms!!! It's a whole world of crazy analogue percussion instruments in my DIY offerings these days.

I have more of my own design in the works as well! :yay:

Hello hex !
Clap, snare vcnoize and batery acid work perfectly here !!!
I finally find my newbie mistake, i connected the ground on the second signal inlet...

I've just restocked PCBs and added some eurorack panels for this project in my shop :cloud:

the clap sounds great and worked first try (with Re:Synthesis panel)
right now i'm waiting for a bunch of pots that i hope will be here before the weekend and once i've completed the rest (and they work too, fingers crossed) i'll make a video. it's just the kick and clap so far.
looking forward to the mutant cowbell and hats of course.
are you planning to do some more of the ateohate sounds (or other drum legends)?

I wanted to box up my Bananeurysm/Anesthetic Audio 808 kick drum module and my neinOhnein clap in the same box to create a "sidecar" type expander for my TR606 - giving it what it lacks (flexible kick and clap!)

curious to see if i could run them off the same supply I put bipolar 9V to the clap and can confirm it works great. I don't know if it sounds identical to higher voltage becuase I haven't tested it with that supply yet but, it sounds like a 909 clap to me but something I can make 'my own.'

So if anyone was curious to power it at a lower voltage....it works.

I used a little power conversion circuit too to get +/-9V from a positive 9V supply. You can find these for 'effects pedal' circuits - like this one: http://www.generalguitargadgets.com/com ... gory_id=23

Uses a MAX1044 chip to do the conversion. So you can have a unique drum sound or several powered from a typical guitar pedal supply. Some loss of headroom but not very noticeable in my opinion

Sweet! That's awesome. You should photograph your project! It sounds cool.

Very nice clones from hexinverter, after some troubleshooting all of them are up and running smoothly in the modular. The exception is the 909 clap. I have a problem with the Intensity, which isn't effected by the 50k pot voltage divider at all. It seems to be at full intensity all the time with much too much decay. The voltage on the collector of Q7 is changing though. I have made an adapter for using ½ 13700 instead of CA3080, but this shouldn't bring any noticable effect or what? Before I substitute any transistors, I wonder of any one has a clever idea what could be the problem. The PCB is thoroughly checked for errors.

Thanks!

Sorry, I've got nothing for ya!

But yes, the LM13700 should be a perfectly fine substitute for the CA3080. I'd go over your connections and make sure that you've connected it right. The pinouts are of course nothing alike :omg:

Thank for reply. The adapter for 13700 works just just fine. When listening to samples from the Clap, I got the exact same sound as when in full Intensity. Ive spent many hours checking connections, orientations and discreet components, all seems fine. Perhaps I must try substituting transistors :(

I'm working on this build right now. (my first eurorack build)

Just wondering if anyone knows off the top of their head what size drill bits to use the for the alpha pots and the 3.5mm knobiconn jacks?

Since resynthesis is down I ordered blanks for synthrotek

Also on Hex's pcb mounting video, the sheet metal screws look quite long for attaching the PCB to the metal bracket. Do you typically just hacksaw off the screw to the right length once installed?

Thanks!

EDIT: I figured out the drill bit. Still wondering if people just cut off the screws?

What kind / size of header pins do you use for connecting the noise board? I'm having a hard time figuring out the right ones to use.

I pulled these from a different hex project:

http://www.mouser.com/Search/ProductDet ... 1-124-20LF

http://www.mouser.com/Search/ProductDet ... 0-01-20-RB

but the male pins say they are .48 inches and I'm worried that won't be long enough to clear the socketed ICs

If anyone can let me know what size they used that would be great!

Thank you
