Just wanted to share an idea. It’s basically 3xCadet VI faders smashed together with Slider Potentiometers and Normaled inputs. I’d like to be able to crossfade between two 2RGB signals.
I don’t expect anybody to go through the schematics (it’s the first time I draw one, and its a bit chaotic).
But I would appreciate any tips on sandwiching? It’s probably going to be a 10HP sandwich design with smt components DIY friendly.
I’ll try to order a test pcb over christmas and start the new year with this new exciting project
Wish me luck.
Something like this for the interface:
First three columns of thonkiconns are In-A, xFade, In-B , the last column is out RGB.
did you add capacitors around the powerheader (10uF electrolythics) and 100nF capacitors next to the IC’s? I don’t see them on the schematic. Look at Cadet schematics for examples on this.
True! the power section is not there yet. Thanks!
Nice!! I want one… my recommendation make the INPUT normalizations cascade (similar to Passage) that will be the most flexible o all combinations :), including both A/B inputs and CV. Also dont be afraid of doing it SMD 0805 is big enough and ICs are ez to solder even the inexperienced.
A1 > A2 > A3
B1 > B2 > B3
CV1 > CV2 > CV3
I use my current 3x Faders for this task and this layout looks ideal. Agree with normalizing inputs, it makes patching way less messy. Hope you can turn this into a DIY project for the community!
Normalized inputs are already in the schematics, I think that part is correct.
Should I buffer the first inputs because of the cascading? Or is it ok like in the original cadet circuit?
The idea of this project is threefold: give back something to the community, enrich the video DIY universe and learn the process of creating a module. That’s why I chose this ‘easy’ design. I have more ideas, but let’s test this one first.
What about adding a flipflop to each fader? So you can switch A<=>B with triggers for animation…
I would LOVE to have a fader with either some flipflops or a simple AD. Thats basically a LZX Pendulum but with triggers input.
Thats very interesting.
An analog switch would do the trick, maybe this: https://www.maximintegrated.com/en/products/analog/analog-switches-multiplexers/MAX4760.html
Didn’t really check the bandwidth and other specs, but some chip in that direction.
That will change the layout, though. I didn’t want to go bigger than 8hp…
But if the analog switch is fast enough, it could even work as a threshold.
I’d be interested in one of these. It looks really handy.
This looks super cool. I would be interested as well if you did a run of them.
