I'll be putting some of your PCB's in a seperate box and I need to check if all the PCB's will fit.

Are you planning any mod's like you did for the Rim? That would be nice to know when making the panels.

Cheers,
Heya!

Let me get back to you on the dimensions (I'm making a page on my site for these shortly)!

As for the mods -- not with the clap, I do not think. I'll goof around with the circuit a bit once it's here but I cannot say for sure yet as I don't have one in front of me to mess with until the PCBs arrive :)

I have in the past prototyped the PCBs/circuits at home via home etching or breadboarding, but it simply takes too long for me to do that with all the other projects I have going nowadays. So, I have to wait before I can answer that for sure! I doubt I will be modding the clap at all though! :tu:

Do you think you are going to have all your drum pcb's in stock at some point, would like to buy one of all in one go....

Hiya!!! Thanks for your interest :)

At the moment, the only one I could possibly see not being in stock when the clap/toms/snare come in is the 909 kick. Otherwise, I should have them all within about a 1-1.5 months. It's just a matter of verifying the clap/snare/tom prototypes and sending out the new board order once the prototype boards are here (approximately 2 weeks from today)

Hope that helps you make your decision :) Cheers! :tu:

UPDATE: I have now updated my site with all of the board dimensions.

Scroll down to the PCB renderings and there is a new one with the board dimensions for ya! Here it is for posterity's sake.

Cheers! :guinness:

can I pay for them already? And you send when all arrive, don't have to pay shipping twice, don't have the time anyway right now to build anything....?

I would also like to buy all of your drum PCBs in one go!

Oops! Sorry, I missed this post until now somehow :(

Sure thing -- I can hold stuff, no problem! Just shoot me an email: hex[at]hexinverter.net and we will work things out.

I finished building the clap prototype today -- it works and sounds nice! :yay:

I also discovered a fun control to add to the front panel -- the 10k trimpot that tweaks the sound is actually really useful for adjusting the decay/intensity of sound being made, so, the panels from Re:Synthesis and myself will now have an "Intensity" control on the front panel as well for some unique tweaking of the clap sound that you won't get from a stock TR-909 :banana:

I will record a sound demo as soon as I have time! For now, I have to go sleep :( :bang:

Why thank you sir :D

I am at present experimenting with some other modifications to the circuit for more panel controls.

The 909 clap is such an iconic drum and yet it has NO control over the sound, so, I am experimenting with different mods to add control of the sound generated by the module. It seems somewhat of a shame to build a module out of it and not have actual controls for it :tu:

:tu: Definitely agree about controls. Modular is all about having MORE. 'Cause MORE is MORE!

So far I have added 3 more controls on top of the base volume control, for 4 knobs total. I think that's all that will fit into a small panel space in euro :cloud:

PLEASE NOTE:

The NeinOhNein CLAP BoM has changed! Please delete and re-add the Mouser cart to your order if you are planning to get parts for this project when it comes out! I have added 1x 50kB pot, 2x 100kB pots and 2x 1k resistors. I have removed a 47k and 39k resistor as well as the 10k trimpot from the BoM.

Stacy, about the noise daughterboard. i have the noise part already on my kick module. can i just hook them all up to that one output or is it better to make one of these too?

Yes indeed! There is a point marked "RAW" on the kick and all of the other boards that use the noise gen -- just daisy chain them all on that and they'll all share the same noise generator! :tu:

Hey Stacy, how many modules we can chain to share the same noise chip?

Theoretically speaking, you should be able to connect a LOT. More than are connected in the same way to one common noise generator in the TR-909, that's for sure. :)

Cool!

So, I will only need 1 4006 for all your drum modules!

Ah good to know . but i may keep them seperate anyway
just ordered a few more modules from you.
should just about round out my drum rack nicely.
if you end up doing the triggerhappy i will need a couple i think
It probably wont happen today but if it does it definitely wont go smoothly.

Yes indeed! :) Actually, there are 2x CD4006 per noise generator. You only need one noise generator though :banana:

Forgive the somewhat paradoxical question, but can the 909 clap, with mods installed, sound significantly un-clap-like?
