Things You Can Build With the CD4049UBE

[H5N1]

I have some CD4049UBEs lying around and am tying to make a plan for them. 
Could you all help me make a list on this thread?  Maybe you could post the project name and a link or a photo for each one.
Thanks,
-H

You Beat me to it!    Yeah, I'd totally recommend that one too.

Thanks all, keep 'em coming!

Loads of good stuff here http://www.runoffgroove.com/articles.html and here http://www.geocities.com/tpe123/folkurban/fuzz/snippets look at the 4069 based circuits and just sub the 4049 in.

Another good one is the MXR Envelope filter.

Finally some ideas from the forum http://www.diystompboxes.com/smfforum/index.php?topic=48815.0. The Twenty Two Sevenths is a killer

2 effects come to mind: runoffgroove.com double d and the Hot Tubes circuit at gaussmarkov.net

Although the 4069 is also a hex invertor, I doubt that one can simply pop in a 4049 wherever a 4069 is called for and vice versa.

So, with that qualification, note that the MXR Envelope Filter and mini-theremin use a 4069 not a 4049.

also note that there are many brands of 4069 that are known not to work in the MXR env. filter.

That's right.  The 69 has 14 pins while the 49 has 16.  However, I've built a socket to convert a 69 to a 49 pinout and there's really no significant difference in sound.  The 69 consumes a bit less current, though.

If anyone is interested, I can post the diagram for making the socket.

Good shout Mark... I should pay more attention. Sorry! I thought we were discussing a 4069UBE. Since I have checked the pinout of the two devices and it appears that they DO NOT have the same pinouts. I'm not sure, but despite this maybe in the minimum theremin it may still work with a new layout. Probably not worth the hassle even if it would work mind. You'd be better buying two 4069 chips considering they are pretty cheap and time is money.

Please do.  I have a box full of 4069's and only a few more 4049's. Thanks for runoffgroove. com too! I've spent a lot of time there.

Good point Mark, I should of explained myself better, you can't just physically replace a 4069 with a 4049 or vice versa, because of the different number of pins. However in my experience you can happily substitute one for the other on the breadboard or if you make your own layout, I've tried most of the Tube Sound Fuzz type circuits and they work fine with either.

I haven't tried the MXR EF with 4049s, but I'm pretty sure Steve Giles has.

I should of added a big YMMV to my post

Hi
I would definitely go for the Runoffgroove Double D. I have built it my self and really like it. I have also tried the 3 legged dog and the Red Lama but the Double D beets them both in sound versatility since it has two channels.

Link to my version, the Viper. It shore has got a bite with a fang

The minimum theremin, oops sorry, I did that because I mistakenly built my min theremin using 4049 chips, even with the different pinout, and it works fine... well to quantify that, it doesn't sound like the soundclip that Mr Harrison has on his site but it's definitely a theremin. His sounded kinda OOHee as opposed to mine which sound kinda AAHee. I didn't even use CD4049UBE either. Mine are MCI4049BCP's so the leeway, on that particular circuit, with these things may be alot larger than previously imagined. So I'm thinking that different hex inverter arrays maybe offer different voicings.

Different pinout meaning I designed the PCB from scratch to use the 16pin 4049.

Re: the 4049/4069 equivalence/inequivalence.

Comments about the use of adaptor sockets and breadboard/perfboard/vero builds are entirely appropriate.  I'm just glad we staved off a bunch of "it-doesn't-work" threads that resulted from someone using a PCB layout for the one while employing the other.

Yes I did, but on breadboard, it worked very well
