I’ve been recently thinking about the circle drone of doom and a potential modification to make it a bit more sonically variable.
The idea I had was to add a push button (one that doesn’t lock) after the central switch for each oscillator. The idea I had was to have this switch behave based on the switch position. If the oscillator switch is off, when you push the button it turns that oscillator on for as long as you have the button pressed. If the switch for the oscillator is on, then button mutes (turns off) the oscillator for as long as you hold the button.
I enjoy the circle drone of doom, but wish it had just a little more variety in how I can interact with it. The idea is largely based on the idea that by pressing the button with effects on the output, things like reverb and delay can have a more interesting impact. Also worth mentioning, I don’t intend to modify my existing circle drone PCB, I know that’s just asking to destroy the PCB.
So the question I had is if anyone has any ideas for how to achieve this? A few ideas I had was to use maybe a flip-flop circuit or a timer IC. But I couldn’t work out how to make the button behave opposite dependent on the switch position. Any ideas on how to do this would be appreciated!
By my understanding of the two way switch, that usually uses 2 latching switches, is that how you suggest achieving this, or can this work with non latching switches. Sorry if it’s a dumb question, I’m still learning electronics.
If you use one latching switch and one non-latching button(=momentary)
It will work the way you want. The position of the switch will determine the effect of the button.
If the switch is in one position, then pusing the button will activate the ‘light’. If the switch is in the other, the light will be permanently on but goes off when the button is pressed. I would suggest just putting it together on a breadboard to get a feel for how it works.
Btw the button does need to be SPDT with one side momentary for this to work. Using a SPDT (ON) - ON switch instead of a button will work exactly the same
Okay, I think I understand what you mean, and yes 100% plan to try it on a breadboard first. I built a single oscillator from the oscillator of doom schematic today, but am short on the correct buttons or switches to make this work for now. I’ll have to wait until an order arrives to continue. Based on what you said, it sounds like I would need an SPDT button as well right?
Appreciate your help, and will comment back if/when I get it working.
Any suggestions for components you know of for this? I’m struggling to find a SPDT button with an ON-(ON) arrangement. I might not be searching the right thing, but I have so far only found OFF-(ON) buttons and most seem to be SPST.
Thanks a bunch both of you for your help, I managed to mock up the circuit successfully using some of my leftover components. The switches works the same way an SPDT button would work, so it proved exactly correct. Such a simple modification for a little extra fun! I took a quick video of the circuit in case anyone would like to see and hear the result. Really appreciate the help even if it was quite a basic thing!
