Voice Assist Puck

Updated 1/15/24

changed the dev board to an esp32-s3.

redesigned pcb for new dev board

redesigned puck to be simpler to put together and thinner, looks a lot better too I think!

This puck uses an esp32-s3 dev board with esp home to be a satellite for voice assistant in home assistant.
The .yaml I provided in zip file is based off of github.com/esphome/firmware/blob/main/voice-assistant/quinled-dig2go.yaml. with a few changes for gpio and LEDs.

For whatever reason, I think it's because an esp32 might be a little under powered, the device will crash every once in a while, and will need to be unplugged and re-plugged in, hopefully this gets fixed in the future, but for now this is really just something to play around with.

The design intent for the diffuser and body is to be printed at the same time as an assembly with a multi material printer.

The white material I use for the diffuser is this. it's basically the same stuff you would use for lithophanes.

Any color can be used for the rest.

Body and diffuser should be printed solid, or with enough perimeters and top/bottom layers so the diffuse is solid.

No parts should need support when orientated correctly, orientation should be self explanatory.

The foot isn't necessary, if you want it, it can be printed in a soft TPU and glued onto the bottom.

Non-3d printed parts:

1X 24 led ring

1X MAX98357 I2S Audio Amplifier 

1X 4Ohm 40mm Diameter 3W SPEAKER 

1X INMP441 I2S Microphone 

ESP-32-3s dev board

Connectors if you want them, or you can solder the speaker and LED directly to the PCB 

2X M3 x 30mm flat head cap screws

Gerber zip located in the other files can be uploaded to any PCB manufacturer, I've used both JLCPCB and PCBway, should be about $4 for 5 boards, plus $20 shipping if you want them sooner than months

the esp32 board and the speaker amp board get soldered directly to the pcb, the microphone uses header pins on the other side of the board. see the included pictures of the board itself.
