My build progress

I see a Daisy Seed, what could be a quad op amp, a couple of trimmer pots, another couple of pots, and two more devices at the top that could be audio, and a sprinkling of passive components. And in pride of place you have a miniature breadboard.

I think you’re building a digital semi-modular using the breadboard as a kind of patch board.

DIY midi controller v2.

Progress is slow, but mostly due to motivation. Corralled the cables, all hooked up right. Prolly not going to go with this method again. Its a bit too impermanent. I should be able to get everything in there without it popping loose. Not too big a deal since this is a prototype. Once i get this on pcb it will be a lot better.

The good news is all of the serial devices check in, so thats one worry i can put to bed. I know the cabling could have been simpler, but w/e.

Now im off to code the firmware for this thing. I have tested these in different isolated instances, but you know its a whole different thing when you do it all together. Im looking at all of those unused pins on the arduino and shaking my head. I COULDA ADDED MORE INPUTS!!! If i could only fit them in this enclosure…

Seriously, the MCP23017 could support 3 more rotary encoders, 1 digital, and 10 analog pins on the Teensy 3.2. Id be curious how much delay there would be adding more MCP23017 and how much that delay can be alleviated by using the other hardware interrupt. Im thinking this isnt nearly close to what you can push out of this thing.

Been talking with Tayda to see if they can start stocking rotary encoders, because yall know how much i prefer sourcing from them.

So rad! Certainly is a lot of wires :grin:

Get a Mega Pro, then you have even more inputs unused you could use :wink:

A trio of new modules finished over the weekend - the quad vca and splashback delay along with the MFOS state variable VCF using the PCBs on soundtronics. All working first time! That never happens for me!

Quad VCA is undoubtedly very useful, and the MFOS filter sounds great. I bought the splasback because I can’t say no to delays but I’m not really sure where it’s going to fit into everything - it’s even harder to control than I thought (I know we were warned) and between my boss space echo pedal and my quadraverb I don’t know if I’ll find a huge amount of use for it. Ah well, can’t have too many delays.

Only the midi-CV converter to build and the first case is done!

Hey all, started on my first module, first time pcb-ing. Thanks to the forum members, I’ve already learnt heaps and have started to rekindle my childhood love of electronics.

If you lower the volume of the signal going into the triple Splashback, it becomes pretty reasonable to use.

aaaaah good to know! makes sense tbf

Number of inputs on are less important than the brain. The teensy is just better for my application than the arduino.

This can work with an arduino nano, but i would need to use midi 5pin din and power via usb, and the speed might bottleneck. I am considering a variant that uses a nano to reduce costs though absolutely, since thats what I used before in v1.

Sturdier case! But yeah, hopefully wont sit on it until after i get the firmware written and am happy with it at least. :slight_smile:

That is a good idea do this myself. Thanks.

the only problem in my situation is that there are only a few threads coming through the face plate on most potentiometers , nuts hold ok but no washers can be used . this depends on the thickness of the face plate and bracket you use .

Made a protection/travel case for my SHNTH and a Pedal.

Also built this Little Mix from Analog Ordnance (far left)

Ladies and gentlemen, here we have another module that works the first time. And it does its job really well! It’s the MS20 filter WITH HP / LP switch that I built a few days ago. Today I was finally able to test it. I’m really happy not to have to look for mistakes for once :slight_smile:

Next Project is the 5 Channel Mixer from Niklas Rönnberg

What’s that in the background, a SPICE simulation?

:laughing: This is a cutting board made of glass with these motifs on it. Is very practical as a soldering pad, etc.

So to be absolutely clear, you didn’t just lay out your finished module on a worktop strewn with nutmeg and whatnot? It’s actually a trompe l’oeil?

Finished a Barton Waveshaper today:

I added a few LEDs to the original design so that I can see that there is an input signal and the counter is running.
