I agree, I ended up putting two panels on it for this, but current consumption is probably the biggest concern still. I will probably replace it once I get my parts off of back order.

I highly recommend esphome if it covers your use case. And MQTT can be implemented in esphome if you prefer that

Upon reading more I really thought I2S had more in common with I2C but turns out it does not. I2S is still a good protocol and there are probably boards that can bridge the gap between i2C or usb

If you have I2C access available there is a protocol called I2S that is specifically for audio.

Having tried both which do you prefer between the influx dashboards and graphana?

This is fantastic. I have been doing something similar but this just has such a nice tech stack all put together. I had no clue cargo existed and this will a good push to try rust.

These are absolutely fantastic, 3D printed aids helped tremendously in my physical chemistry classes and these take it to the next level.

If your bed isn't unlevel then you may be under extruding due to a clog in the tip.

I would really recommend getting your buck converter up off the bottom. It looks pretty lush where you are at and condensation may pool in your case and short out your board. Super clean build and very cool. I might build one myself!

Why not just cut out the chip and tape it onto third party spools. At least the ones on the Bambu ams are just RFID so I have seen people order normal sunlu filament of the same color and just reuse the chip.

This is super cool! Is it particularly loud at all? I always see the spinning hologram things but as cool as they look I imagine they sound like a helicopter. I bet the enclosure helps a lot.
