/diy/ - Do It Yourself

Hello guys

So I'm building my own MIDI controller.

http://www.instructables.com/id/A-Framework-For-Making-Affordable-Stylish-Modula/?ALLSTEPS

I'm going to build it following this guide.

I already have ordered my Teensy 2.0++ and more or less understand the whole thing.

The problem is that the electronics stores are very lacking as I live in a small town in Mexico.

It says I should get a CD4067BE Multiplexer, but I can't find that in any of the stores. They do have other multiplexers though.

My question is, can I find a different multiplexer that does basically the same thing? I'm just starting in electronics and am pretty uneducated in the matter.

I also can't find them online as they sell them in bulk (I would have to buy 315 at least).

Also I'm in a bit of a worry here as I have no idea of how much wire I'm supposed to buy. Any input would be appreciated.
