There’s no better introduction to signals and systems than a modular synthesizer IMO - the combination of tactility and audibility for multi-sensory learning is so great at building intuition - and more importantly, excitement! - for signal processing. This looks like a cool project in the same spirit!
I was going to say the same - does this follow 1V/octave standard, and is this available in Eurorack format? ;-)
TL;DR: No.
I looked into it hook one up to my rack and ultimately decided that even with the high price of euro modules it's still not really sensible/useful for what it includes. There's a lot of more useful modules you can try the same vibe with for euro though.
For analog logic, Maths from Make Noise is the obvious. ANA from Mystic Circuits is pretty neat too.
For digital logic (Combining both types of logic is very fun IMHO) O_c (or uO_c) running hemisphers has a mode to construct complex logic gate changes in the module, which can be fun.
Also, consider that a LPF is effectively an integrator and a HPF a differentiator and you already have 90% of it already, probably.
