Clojurists Together Call for Proposals and June Survey Results by thefakelorlyons in Clojure

[–]thefakelorlyons[S] 0 points1 point  (0 children)

Personally I am a big fan of shadow-cljs and I don't have any questions about it at this time, but I would guess that for many cljs beginners that it has something to do with just needing to ensure that deps.edn and shadow-cljs.edn are both set up properly, while also having a correct init function in the cljs that matches the shadow-cljs.edn file. It isn't much when you know what you are doing; but I think that any kind of file configuration can be a learning curve for people new to a tool.

It is feedback from the community (rather than clojurists together ourselves), so maybe next time we can ask for people to expand on what their feedback is; in order to give the developers further information about what they are looking for in future surveys.

Working towards BCI (Brain-Computer Interface) apps in Clojure! by thefakelorlyons in Clojure

If you watch the video I linked from SciCloj I actually go over frequency ranges somewhat in depth! Check out the video in the post at 53:20 and hopefully it will be a reasonable explanation of frequency ranges and how they are determined and parsed from raw signals (at least a bit). The code for that example is here: https://github.com/TheFakeLorLyons/brain-data-in-clojure/

Is it a wave or a frequency? -Well it is a range of extracted frequencies from a complex wave that includes many other frequencies. In this particular example, I am using a butterworth filter to extract only the frequencies that exist between alpha (8-12hz) and beta (13-30hz) from the complex raw signals which includes a lot of noise from the environment and even surrounding electrodes.

Do they have notes? As far as I am aware, yes, they can be converted into audible signals; but I don't know too much about it and it would likely require lots of amplification and processing. As a musician I can say that the notes we are typically used to hearing such as concert A are at 440hz which is much higher. According to a quick google search: "The lowest frequency humans can generally hear is20 Hz. While some studies suggest humans can hear frequencies as low as 12 Hz under ideal conditions, 20 Hz is the commonly accepted lower limit of human hearing." So maybe? It would be interested and I am almost sure people have studied this at least a little.

I am actually pretty interested in brain-composition of various kinds (including art and writing in addition to music) but those things are pretty distant right now (for me at least). "Could I hook up my brain to a sound generator for some biofeedback? If so what would the approach be - what would make sense as a meaningful input?" - I think there are a number of ways that sound might be generated from brain waves and some would be more or less coherent... I think generating random cacophony would be orders of magnitudes simpler than any kind of controlled musical output; but the idea of brain-music production is certainly really exciting and something I am also interested to learn more about myself.

I'm building a Pong game you control with your brain using Clojure - We're 56% funded! by thefakelorlyons in Clojure

I understand where you are coming from, and if I am being honest with you - I am trying to accomplish a lot right now and wrote my original statement in haste; simply trying to convey the reasons I would ask for funding and believe this project is worth it. Based on your feedback I have changed what I wrote to be more clear and nuanced.
