Switchapalooza

I don't know if anybody else is as exited as me but I've been playing a lot with CMOS switching lately and it as open a lot of opportunities and ........ it's a lot of fun!

I've only played with CD4016 and CD4053 up to now.
I've learned what I know from sites like:
http://www.thetonegod.com/tech/switches/switches.html
http://www.geofex.com/Article_Folders/cd4053/cd4053.htm
http://members.shaw.ca/roma/switching.html

I would like to start this thread so people could post other switching tricks.

Like using CD4051, CD4052. Using counters like CD4518 and CD4520.

From my research (correct me if I'm wrong!) I gathered that using a CD4051 controlled by a CD4518 would give me a 8 position single pole switch and using a CD4052 controlled by a CD4520 would give me a 4 position dual pole switch.  Is that right?

I hope this thread works 'cause I'm sure there are lot's of fun ways to use these CMOS that I don't know off!

Good example here http://www.cgs.synth.net/modules/cgs28_seq_switch.html

The Echo Base uses CD4066/CD4016 in the switching http://www.aronnelson.com/gallery/main.php/v/slackers-stuff/album170/echobaserev2.png.html I used the same sites you linked to for inspiration.

Thanks for that link slacker!

After looking at the link I realized that my previous statement:

From my research (correct me if I'm wrong!) I gathered that using a CD4051 controlled by a CD4518 would give me a 8 position single pole switch and using a CD4052 controlled by a CD4520 would give me a 4 position dual pole switch.  Is that right?

This is true but not exclusive. I realized that both the CD4518 (BCD counter) or the CD4520 (Binary counter) could control the CD4051 and CD4052 since you only need the first 3 bits (from 0 to 7) and that's all we need.

Man...learning if fun!!!

indeed, you have to watch how you mix your binary and your BCD ... you can cascade BCD counters for multiple digits ... what is a real pain is trying to display hexadecimal. The easiest is likely going to involve microcontrollers.

This is a cmos switching scheme for having two effects in one box, and when both bypass switches are on, you get a parallel mix of the two effects rather than a more traditiona; series arrangement.
