Hi:
Here is my PCB design for the Craig Anderton Hip Bass Drum, I etched the
PCB some time ago, but never had the time to finish it, so is UNTESTED.
If someone get it to work, or find an error, please let me know.
The scan of the article was posted here at electro-music before, but I think
the files are lost, so I re-post it.

** edit: stinkebeest tested it and it worked for him **

Is there any quick way to turn the eagle file into a stripboard layout?

I don't think so, you could build it on perf board by following the PCB layout.
I might have a crack at a stripboard layout, it doesn't look too complicated.

Hey Sebo,

I used your layout for my Hip BD, and it works great ! So, thanks a lot !

I added the trigger led circuit that you left out on a little piece of strip board ,cause well, me likes the blinky lights Wink

So, did anyone else build this ? cause i'm having a litlle bit of a problem
with the PW (or "thud") control. all the way CCW, the device stops being
triggered all together, and all the way CW, it gets into some sort of spastic,berzerker trigger frenzy. in between it sounds great, awesome circuit, but still, kinda wierd this thing.

Cheers,

Rudi

Hi stinkebeest:
I just noticed the last 3 post in this thread, I didn't received any notification,
for some reason it's happening very often to me.
I'm glad the layout worked for you, I didn't finished mine, it's floating around
with some resistors soldered an nothing more. I will work on it soon.
I have no idea what could be causing your problem, but a simple solution
could be to add a small value resistor at each end of the pot, this way you
never reach the problematic points.
If you could post some samples (of the good working sounds) it will be great,
as I'm very curious about how it sounds.

I think bbob is correct concerning the Hip Bass Drum ....sort of. I seem to remember a review of it in Polyphony Magazine and the reviewer mentioned that it was a compromise between low parts count and functionality of the controls.

Hi Sebo,

But you know what's really weird ? i didn;t get a topic reply notification
from your post either. but then i did when dan replied.

Dan,you're absolutely right. after looking over it some more, and getting
to know a lot more about electronics... this thing really gets the most out
of VERY few parts, and therefor has some minor disadvantages.

Sebo, that's exactly what i did ! adding some series resistors, works like a charm now. i'll try to make some samples soon !

Cheers,

Rudi

Hi! I know it's an old post, but I think it's better resurrecting this one than starting another.

I've just build the Hip Bass Drum in a piece of stripboard and I can confirm it's a very nice and easy circuit. As the other people have said, there's some minor weird interactions between the controls, but nothing terrible. It's working great here with a +/- 12v eurorack power supply.

The thing is that I want to use it in my modular, and I would like to install a pushbutton to trigger the drum, so you can tune the sound and play it without a sequencer, etc... I haven't studied electronics; the few things I know I have learned it myself, and this is the first time I deal with this trigger thing.

So I've tried a couple of things I found in the web: one of them involved the pushbutton, a capacitor and a resistor; the other one added a 2n3904 transistor to the circuit. This are classic debouncing circuits if I am not mistaken, but they are not working for me. Ok, they work, but not perfectly. When you push a little fast, sometimes the button triggers more than one sound. On the other hand, sometimes it doesn't trigger anything or the drum sounds different between pushes. This happens only with fast presses, but it's a little annoying. I've tried using higher capacitors 2'2mf, 4'7mf, and it seems to get better but the behaviour is not perfectly predictable or consistent.

Is there other things I can try to solve this? I thought it would be less complicated to sort this out...

I didn't finished the Hip Bass Drum yet (a shame really).
But I think you can try some of this circuits to trigger it:

Thanks Sebo for the help! I will try these, and the CGS gate to trigger converter as well. Let's see...

Hi!

Great thanks to author!

I have some no-name pad (with simple microphone inside), i've been wondering if i can use this DIY to make electronic BD?

I belive so. But, if yes, is there any chance to record how does it sound?

Regards!

Hi there.. i'm finishing my hip bass drum soon, its great.. i'm still having some problems mounting it.. cant wait ro record it... Sounds great!

Keep u updated!

Sorry for being delay, too much work here..
Here are the samples, remember, i'm still working on it... i have to check the click level connection, it is working as a whole volume pot.. so maybe i´ve made a bad wiring work... also need to check the compressor seems to be not working at all...
As you see if the resonance go hi it oscillates and can generate longer tones...
ii'mreally happy with the sound Smile
Now its working on two 9v batteries and have been recorded with a fast track pro soundcard.. had to put the pad at the input.. the gain is really HIGH!
Hope this samples gives you an idea of how it sounds, and also i hope to be doing things right here !! jjejejejej
cheers!

You did overdrive a bit your sound card i think. Try to lower it a bit.

Hello !!

HIP Bass Drum, that sounds good to me.
Good article and thanks for the layout.
This is what I made off it so far, ready to ets the pcb board and make the front panel.

Grt,
Chris

Any chance of getting this to work with a resistor voltage divider.

Iam really not fond of +/- voltage personally i feel if the circuit can work with just positive voltage it should be designed that way.


Although this might just be me not wanting to get a +/- PSU ;D

Here is a stripboard layout for the Hip Bass Drum. I made a working one from this layout but check it all the same as it was a long time ago and it might have errors.

I builded this Module after the Layout KRS1972 posted here. Unfortunately its not working yet. Though i am not sure if its the fault of this circuit or the Trigger, wich is not working properly. Maybe you can help me find the error? I try to describe how i trigger it:

The clock is a CD40106, giving out a squarewave with a high of 7,7V(checked it with the multimeter). Afterwards its going through this Gate to Trigger Converter:
Posted Image, might have been reduced in size. Click Image to view fullscreen.

I have built just one of the Converters, using just one Half of the Op-Amp, and i obtained the Transistor-parts.
The signal wich comes out of the Converter, when i check it with the multimeter, is just 0,22V! But it could be, that this is just because the high is so short, that the multimeter doesn't have enough time to trace it.
When i listen to the output of the Converter it gives out a click in sync with the clock speed. its as loud as the click from the clock itself, so i think its probably also the same amplitude.

The Bass Drum itself, is giving out mostly Humming, but you can hear the rythm of the clock through it. none of the Controls actually change anything. The Trigger-LED is iluminating with every trigger. But the LEDs mounted to the Limiting-Switch are not glowing.

Do you think the problem is the Drum or the Trigger-part? And any idea on problem shooting?

Thanks a lot

For what you said, I'm pretty sure the problem is in the Bass Drum circuit.
Also I think you don't need the gate to trigger converter because the input of the Bass Drum have a very similar circuit...
First try to connect the output of your clock circuit directly to the Bass Drum.

Oh okay, good to know. Seems you are right. at least according to the trigger-LED its working without the Converter-Circuit. Still no Sound though. I am off, troubleshooting Smile thanks so far!

edit: I found an Error: When i have the drum circuit disconnected from everything, i can measure 10V at the output. when i connect it to the Converter-Circuit, i can just measure 7V. when i connect it straight to the Drum Circuit, the Output-Pulse is just as low as 0,5V.
I placed two resistors as a voltage divider after the clock-output, to lower the pulse to 10V, since 15V (wich is the original amplitude) might be to high. Could this Voltage Divider be the problem? Do i need a more sophisticated way to lower the amplitude of the pulse?
