Very nice! If it were for more permanent use, it looks like the lid is deep enough for at least some modules. I love the idea of a test case.

Unfortunately with clearances the knobs would probably clash, the is a little room under the main part which could have been dropped a little but its still very close.
Its proved useful already. there’s enough space to get a fullish simple setup.
when my 2.5 ADSR turns up, that my join the permenant crew…

Ok, a bit more soldering, some drilling, and some solder bridges later, and the first production run is finished.

Not synth related, but I wanted more space so I built another lighter weight workbench. Also planning on putting up more pegboard. A bunch of the containers for synth parts come in boxes with hang tabs. Might as well take advantage.
I also got two buffered multiples in the mail and built one yesterday. I’m finally getting to hear what this synth can do. The other is waiting on more 10 M resistors.
I went with red/blue LEDs. Love it. Might even swap the green oscillator tuner LEDs out for blue (and more accurate 10k resistors).

I’ve been at it hard the past couple of weeks. AR - Delay -Dual Sub Oscillator - MS20 Filter - Buffered multi - Tuner - Bass++ - Wave Shaper. Also Steiner filter with no panel. Working on a sample and hold and a Sync Lfo now.

Still assembling components, but i am taking what i learned from my ass-crushed diy midi controller and making a v2.
This is the current layout i am thinking of using. The marker is to help me not place components where molding is. I have tried to use all of what my ambition wanted to include in this project, but this leads to a pretty compact area. Once i have the physical components in my hands it will be easier to tell if this is feasible.
The 16 knobs at the top will be the pcb mounted alpha pots (knurled style).
The five knobs at the bottom are rotary encoder modules. The top two will interact with the OLEDs above them, and the other three will be for other functions.
The OLEDs are some SSD1306 modules. Small, but big enough for my purposes i wager.
The keypad is a 4x4 module. This one has clear caps that lets you label them. Snazzy.
The brain is a teensy 3.2 this time. This is because i wish to use the onboard usb as power and midi interfacing. V1 used a 5 pin din midi and the usb with an arduino uno. One less cable. More money, but i think worth it here.
This layout is far from final, but this is my ambition and latest project. I simply cannot find any midi controller that does what i want, and even the ones that come close like the ones faderfox makes are outta my price range right now. Even if i fail, i feel that the experience from this will be more valuable to me. Sides, i learned my lesson from last time and will forgo the “sit on the project” stress test. Also bought a proper box for the project this time.
Along with all this, i got proper tools, i didnt even have a dremel before, yet i wanted to cute squares. I was banging rocks together, and i feel a lot better equipped now.
Wish me luck yall.

nice collection of parts…
rotary encoders are one thing i need to work out… without the expensive i2c modulse they seem tricky to do in any number other than one or two…

I usually dive head first into these things. I will of course share all of the details should it go well.

After last time, i figured that i should at least go with a junction box or something a bit more posh. They arnt that expensive, and in fact i saw some neat “sloped console” types that really remind you of a space ship. Prolly will go with one of those one day too.

Ouch! Pretty sure that’s solving the wrong problem

For the encoders you need hardware interrupt pins! I don’t know how many the teensy has, but the Arduino Nano only has two and I had troubles with running my two encoders with it… it worked great with two interrupts for a single Encoder, but I needed two encoders, so only a single interrupt pin per Encoder and it misses steps quite often… :-/ could probably improve on it by making my main loop faster… maybe it works better on teensy because it is faster!
Just keep that in mind, I am sure you are going to solve this much better than I did!!

Be careful-this one looks like it has a little less give than v1.0. Don’t injure yourself. But if you do, you’d have the least embarrassing reason ever to buy a hemorrhoid donut.
