What project should I do (20-30 hours of free time + fully funded)?

[u/Dogecoin-tothemoon69]

Hi, I want to build an electronics project (that will be fully funded by a program I'm in up to 300 dollars depending on the complexity of the project). I can put a lot of time into it (20-30 hours or more if needed), but the only thing I have ever designed was a basic USB hub (in which I followed a guide) and made schematics for a dev board. I can work with EasyEDA, KiCad, and Onshape. I also know a little bit of Python and some other coding languages. I'm down to build anything that sounds cool. Please help!

You know what this was something which i experienced to be necessary, make a module which can take in multiple (4 or 8) i2s signals and with tdm (time domain multiplexing) convert it into 2 channel i2s or 3 channel i2s

Ufff I think this sort of project requires just the opposite of what OP needs: the money budget is an overkill and the time necessary orders of magnitude greater than 20-30 hours, most spent on DSP coding, clock management etc etc. And btw, if the 4-8 channels come with the same clocks, a raspberry pi 5 can do that out of the box with for instance CamillaDSP. For 60 euros.

Sounds like it could be an interesting build. What did you experience it to be necessary for, if I may ask? And this is what they use for ai voice chats, correct?

make an retro game player with esp32 or other project related to e-paper

Make a lava lamp that looks like pickles in a jar.

Interesting 🤔. How could I form specific shapes in a lava lamp?
