Yes sir! Turning the knobs one way make perfect 909 claps, but, turn them the other way and it sounds like hell :)

I will be doing a little demo soon hopefully!!!

Will there be pcb+panel combos on you online shop for the snare, clap and rim anytime soon?

Looking forward to hearing some audio of these :party:

cool stuff hex, the clap is my absolute favourrite 909 sound, and the mods sound great.

Ill have to pick one or two up at some point, even though i have a 909.

Yes! Audio soon :D I am just knee-deep in other project obligations at the moment :waah:

I am hoping to get some panels in, but, right now Ben is slagged with orders and hasn't the time to make them yet. EVENTUALLY there will be, but it may not be for a couple of months or more!

Things will come around with panels though...you may just have to wait a bit x__x I want them really badly too! hehe

Here's a standard question: Can I use 2906/2904 or BC558/548 for the transistors? That's all I have right now.

Go right ahead! The pinout is different though, I am quite sure...so make sure to account for that when stuffing the board. I think they're swapped around. DON'T hold me to that though. Verify yourself! :)

It is on my (massive) to-do list! :) :cloud:

Unfortunately, more pressing, time-sensitive matters are at hand right now that I must plow through first! The I Dream of Wires module, for example, and, sympleSEQ/other project documentation that I am behind on (shame on me!)

That, and, I don't have a nice panel made to show it off yet. All things in good time :D Sorry for the wait!

I will report back here once that happens :tu:

Hi,

can i remplace the CA3080"AE" by a CA3080"E" ? only the temp range change :
-55 to 125 for AE and 0 to 70 for E.

is it importante for this case ?

Can anyone recommend knobs for the pots in Hex's mouser cart for this project?

I use Davies 1900H clones with these pots :) They work great.

Indeed sir! The IDOW team came to me and asked me to build a fundraising module for them. I am doing this not for profit -- all of the proceeds are going to them to help with completion of the film (post-production costs). It is a completely revamped version of batteryACID that adds voltage control and a compressor. It can act as a basic hardware analogue compressor when the distortion is turned off.

Go here and click the "batteryACID" menu item to see the module :)

EDIT: Oh, yes, it will eventually be DIY project from me as well. I'm not planning to release the DIY PCB or schematics until after the documentary module preorders are over and done with though :)

Stacy, the mouser BOM and the web bill

list 4 47K resistors. However, the ID column only lists three: R3, R32, and R44.
I pulled out 4 for my build and was left with one. I spot checked a couple times and don't see the fourth, but you know how it is when you are staring at the same thing over and over. Is there really only 3 or is there 4 and I have a blind spot!?

Hey Brian!

Good eye :)

There are only three 47k resistors needed. Somehow I wound up with an extra in the BoM/etc.

EDIT: Sorry, I lied. There is a fourth 47k for the noise generator. All of the Mouser carts have the stuff filled for the noise generator as well :tu:

The one line on the Google Doc BoM was wrong though! I've changed it to three, now, but, if you look below at the noise generator partslist in the Google Docs BoM, there is a fourth one there.

Cheers!

Got my 909 clap working today!

There's one minor thing that I'd like to fix, but I doubt it's possible without messing with the balance between transient and noise: the overall volume of the un-modified sound (that is, with standard settings) is very low. Is there anything I could try? (100k "level" pot?) Boosting the intensity obviously amplifies the sound, as does increasing noise2, but those also change the sound, somewhat. I guess that's the point. I can certainly live with that!

Thanks for the great projects. I'll probably pick up a snare and BD PCB and make a nice, self-contained drum-box!

If you've had functional hearing over the last 20 years, there's no doubt you know the 909 clap sound, from its appearance in every techno song, ever. But you've never heard it like this! It's like a "Devilfished" version of the 909 clap sound. Read the annotations and watch your ears! It can get pretty intense.

Note that the first couple claps of each section are pretty low in level. I didn't want to normalize the softer hits to match the louder ones or affect the natural sound in any way.
