Dear @Antichambre,
This looks spectacular! And especially cool, since I was looking to build such a solution myself - without the OLED (but I'm quite the beginner at this so I'm at a far earlier stage).
Couple of questions - if you would be wiling to answer them:
- Which rotary encoder do you use? A standard "24 PPM" one with quadratic encoding? The reason I'm asking is that I was looking for a higher resolution solution, but that is hard to find (endless pot or hall-effect sensor was what I was thinking of)
- What is the exact part number of the LEDs you used? I had a certain bright LED in mind, but if you use a cheaper less bright one, that might suffice (judging by the video)
- Did you solder the LEDs on yourself? Reflow?
- Is there an update to your project site?
- Would you be willing to share schematics in a downloadable format? I'm sorry if this is considered rude (if it was not meant to be open source) - just don't know what your stance is on this.
Thanks for any info you might be willing to share!

Thanks for the quick response - especially after the thread is 'on life support' (not yet a zombie ;)
The LEDs are indeed super bright (~250 - 1000 mcd for the various colours). However, in the setup how I would like to design it, I would use only 4 multiplexed channels instead of your 32, so they would be approx. 8x as bright. Did I deduce that correctly? (I assume the duty cycle of each LED is 1/32 at the most because of multiplexing - or do I misinterpret they way your setup works?). That would mean that I can use LEDs that are 8x less bright than yours to achieve the same physical brightness (while the max duty cycle would be 1/4 in my case).
The PMMA mask is very cool! Did you create these yourselves? If so, with which method? (3d printing, molding, etc.). Again - only if you would divulge this information!
In total - I would be very proud of myself if - at some point in the future - I would be able to achieve something remotely as cool as what you did :)
Thanks again for taking the time to answer my questions!
