One day you will look at that same module and know how to do it!Pr0fBi0 wrote: ↑Thu Jun 10, 2021 7:01 pmfirst off, i really appreciate you two helping me out and pushing me towards building modules from scratch. I really liked the clock divider module posted earlier, but i saw the schematic and picture of it and instantly said....nope....that's way above my skill level
Exactly. You're already doing it!I can sort of do this now. When something isn't working i do have to dig into the schematic to find the part that isn't working (usually outputs or pots) and trace back in the signal flow and check those parts.
Th what will come before why for many things. But all of it will depend on what you add to the mix from a resource standpoint. I always suggest reading old synthesizer service manuals. The two online for the ARP 2600 are very good. The service manual for the moog MG-1 is also very good for learning. Reading about how these old mostly simple circuits work will help. Try to read the circuit descriptions provided with any good kit. And if you can't find those read the old ones from MOTM kits or anywhere else you can find them. All the old PAIA manuals are online at their PAIAtalk forum and since these were written for raw beginners, and are very simple circuits, they're easily understood.where my knowledge stops is understanding what each thing in the signal flow does and why.
But you will also want to begin learning something about electronics in general. For that the forrest mims booklets are good, and RadioShack also has a very good book called Basic Electronics by Gene McWhorter and Alvis J Evans. Their SKU is 62-1394. It doesn't have a Bowkers ISBN but you can still probably find it online at amazon or a place like abebooks.com.
The second book I strongly recommend is Understanding Basic Electronics by the ARRL here:

https://www.amazon.com/Understanding-Ba ... 0872590828
Both of these are simple enough and yet detailed enough to get you on a solid path. They also both avoid some of the mistakes I've seen online in many learning electronics websites. Sometimes these aren't technical mistakes, just poor explanations that confuse more than help.
Books are only part of the answer though. You're doing the right thing by building modules! Keep doing that.
Yes. It will get easier as you use your modules more. That's the REAL beauty and benefit of DIY. It's not a one-time-have-to-get-it-right-forever thing.i did build the AI synthesis 002 mixer which does both cv and audio. i could try to use that as a basis to make my own design, but i wouldn't know where to begin to make changes to add the features i'd want. the complicated thing about modular is it seems like you don't know what you really want/need out of a module until you get further in and can use some things and start to understand how it all works.
You can re-do modules with new panels or kludge in new mods as you learn both what you need or want and also how to do it. A man stranded on a raft at sea once said hunger is a good spice. In the same way having actual modules which are lacking something you want is good reason to learn how to add it!
it's all good. and it's all driving you towards understanding more. As you get more modules -even dup0licates of the same ones- your choices and options greatly increase. As you fix your mistakes -and sometimes the mistakes of the module designer!- you will gain confidence in your ability to fix things which will increase your ability to patch in ways that might have seemed scary before. <--Another big benefit of DIY. If i break it, I can fix it!i'm still trying to understand how mixing cv works. because when i've tried it with the modules i have it did not produce anything like what i was expecting. but i have only messed around with it a little. i've mostly been using the mixer to do boring things like plug my volca sample in and use it for drums.
This one. Start with the easiest ones there for you and see how it goes. Do some of the REALLY simple ones too. You might begin to see how these can be used with the more complex modules you're building from kits. Or PCB-Panel sets which introduces the next level of learning and understanding. How to choose and order parts.<--This can be especially intimidating. But it's not as bad when you're doing the layout too, so many mistakes beginners make in size and type can still be used.which pages were you referring to? the only ones i could find were these two:
were those the ones you mean?
I attached a simple EG that I bet you could wire up from the drawing? And once you do, you might wish it could work from a lower gate voltage. Where you might compare it to the AR in the ARP 2600 service manual and see that theirs also needs 10V gate for 10 V output. Which might lead you to look for comparators and what they do. Let your need an curiosity drive you.
Or you might want to skip some of that and try this one using a 555 or 7555 that I bet you can also wire up from the drawing. It's simply begging to be a dual module. <--Why do i say this?
EGs are great for learning because:
- They're mostly simple circuits.
- You can tell whether they're working -or not- and how well -or not- pretty easily.
- They make use of typical circuit blocks that you will see in other modules.
- The end result is useful no matter what size system you end up with.
^Mixers too. For the same reasons.
I also attached Nicolas W's EG. Vero or Stripboard is a nice intermediate step between kits and full PCB layout. At the Electro-music forum there are *many* stripboard designs posted. Look for those whose build is verified.
And finally two simple min max circuits to play with. I bet you can wire these up too!
Rene Schmitz has a bunch of simple and good module designs on his website.
The real key is to keep going. Know that things will start to come together for you as you do more. And also that you don't need to know how it all works. At all. <--Many just buy kits and ask questions here about what to do to fix it when it doesn't work. They don't care about the why or how, they just want a module that works. You want that too. But by wanting more, you put yourself on a different path. We'll notice that you care about the why and not only the result. We'll help you get there.
