Craig Anderton Hip Bass Drum PCB

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?

Sorry, I don't know.

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!

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
