For some time now I have considered building a 5U synth. Given the price of wood for building a case, the need to build a power supply, dealing with mains power, and +/- voltage, AE modular already solves all these problems. I just bought a new house, and I have no desire to burn it down!
Also I have two Teensy micro controllers with audio shields. Well, 0-5v is perfect for the 3.3V Teensy! Yes, I might need an op amp to get it down to 3.3v, but the audio library that Teensy offers is astounding.
Sometimes you don't realize the brilliance of a design until you look at other designs.
One of my favourite children's books that I read to my kids a thousand times was about a little tiger and a little bear who lived in a lovely little house right next to a lovely little brook. One day, while fishing in the brook, the tiger saw a wooden box drift past in the water which had "PANAMA" written on it and smelled just deliciously of bananas. That induced an intense longing for adventure and far away lands in the little tiger and when he came home to the house (without a fish, because he forgot all about fishing that day) he couldn't stop talking about how beautiful this far away land Panama was and how everyone there would eat bananas every day and everyone was happy all the time. So they took off, locked the house and made their way to Panama. Of course they had no idea where this land was or how to get there, so they asked all the animals in the forest. They asked three different animals who weren't that much the wiser, but being proud citizens of the forest and wanting to be helpful, these animals pointed to the left and said "that way". So the tiger and bear walked many days and turned left three times when suddenly they came to a little house by a little brook which had a wooden sign lying next it and the sign read "Panama". That's when they knew that they had finally reached their destination. And indeed this "Panama" was a beautiful place to live and after they've fixed up the little house (which needed some repair after its inhabitant's prolonged absence) they lived there happily ever after.
My children are now probably sick of this story, and any way they are 19 and 15 so definitely no longer in the mood to listen to children's stories. But to me this story always comes to me when I get bored, or start taking things for granted and find my mind drifting, seeking other things, other places, other shores. One way to remind myself that the best things are the one's you've got is that my home WIFI is called "Panama".
I did electronic engineering at uni. But whenever I think about designing or building anything I get PTSD. I think having a formal education in it can just destroy any enthusiasm for DIY. Making patches and all the infinite possibilities of that is enough for me now. Euro rack seems just too big and clunky. And expensive.
I have a feeling a lot of people with AE systems contemplated the DIY route at one point in time. I know I did! It really is the perfect solution.
Congrats on the house btw!
For me it was the opposite route: I was trying out DIY first, but the hassle of making a power supply, creating an enclosure, searching good ways to test eg An lfo, it was all such a hassle! AE solved all these problems for me, its not only a fantastic instrument, it's also an easy prototyping tool giving you a steady PSU, infinite 'function generator' options, and just connecting over breadboard makes it so much FUN to prototype 💖
The only major downside i can think of is the limited space: it can make the diy aspect challenging, as a lot of the 'classic' diy resources use chunky protoboard with big components.
