iVCS3 controller

I’m surprised nobody’s invented the vernier slider

Metal work complete. 1mm thick steel plate. Took quite a bit of work.

Awesome. I wish I had the patience and skills to even attempt building a controller. Good luck.

I think this is the same guy who made the epic Animoog controller.

I'm just learning as I go.

Inkjet printed transparent film applied to metal work.

Wondering if I should have gone for white background. Hmmm 🤔

Looks lovely 🙌

Pots fitted. Starting to look like a controller.

Are you gonna attempt to recreate the pin matrix too?

I can't. The app doesn't allow any midi messaging to control the pin matrix.

A so-so workaround could be to use iOS Accessibility Control and map a single tap gesture on each matrix point to a MIDI note for example, but these would be "blind toggles", maybe best controlled by momentary pushbuttons.

Thank you,
for your good information, and lots of love.[SIZE=1][URL="https://gbplus.net/download-gbwhatsapp-apk/"][COLOR="#FFFFFF"]g b whatsapp download[/COLOR][/url][/SIZE]

Yes. I spent a good week working out a way to reliably send out 14bit NPRN messages. I'll use those for the 3 VCO frequencies and the filter cutoff.
Have tried both 7bit and 14bit for the joystick but could not detect a difference.

The tedious joy of soldering

More soldering.

So is it a giant voltage divider in principle? I’ve never looked into how these things work…

Basically yes. There are 3 pins on each potentiometer which act as a voltage divider. All the red wires are joined together and so are all the black wires. The left one (red wires) goes to + voltage, the right one (black wires) goes to ground and the middle leg will go to the input of the microcontroller that has an analogue to digital converter.

I've not attached the middle leg wires yet. That will be tomorrow night as it takes me quite a while but once that's done then that's the majority of the soldering done.

Ah, I see, that makes sense 👍

More soldering. Nearly done on the main wiring.

Only just clocked this… that is some nice, clean drilling. Skills!

I just did this (16 x 9mm holes into copper pipe x 2)… what a pita!

Nice work Kewe_Esse. What is it?

It’s lighting for a market stall/pop-up shop. Builds into a bigger structure for displaying signage/clothing/other stuff… part of an ongoing project. Bit off-topic, hands up, but I feel you on the drilling, surprising amount of work involved.
