here is the complete schematic. Even though every looks about right. I'm getting some weird problems. it used to work just fine, but now for some reason it doesn't function properly. It may be the jum ...

great to hear that works Very Happy

btw you can probably leave out U1c. I forgot that the 4040 counts on a high to low clock transition and I added U1c
so that when you push the button you immediately get ...

You got damn genius. It finally works the way I wanted to work for the longest time. Now I can add the rest of the circuit. And I'll post the completed circuit once I'm finished with it.

Here is a schematic.

This issue has been driving me nuts. So, I have a push button gated 4093 connected to a 4040 IC. The issue i've been having is that whenever I release the button.

The output of the 4040 randomly s ...

Figured out a solution. All I needed was a dpdt switch.

After looking at the schematic on page 157 of Nicolas Collins book Handmade electronic music. I made a few changes to it, like using potentiometers of various values instead of light resistors and add ...

That makes sense. I kinda figured that, but just wasn't too sure about it. Oh, btw that toy organ is from Forrest Mims book. I just then added the debouncing circuit to it.

Hopefully you can see these images. So, as you can see. I tried to mix the 4093 debounce circuit with the 555 timer toy organ. But from trying this out, it doesn't work. I've tried different configura ...

I've been reading the CMOS Cookbook for the past few days and just had a thought. How could I make a sequencer that can record inputs and with a flick of a switch, play it back infinitely? And maybe h ...

So, since then. I've gotten a few new ICs, rotary switches, buttons, toggle switches. Also i finally found some joystick potentiometers, not to be confused with analog sticks.

So a 24 pack? If the pricing is decent, there could be some interesting ones to play with.
