Portable speaker in a bowl

thingiverse

First there was a bowl you can use to eat your breakfast and now you have a speaker! Who needs breakfast anyway? What you need to buy / scavenge yourself: - A bowl with a 155mm outside diameter (mine is from https://www.blokker.nl/blokker-schaal-melamine---15-5cm---lichtgroze/3440440.html ) - a PAM8403 mini amplifier with volume and power knob like this one: https://www.tinytronics.nl/shop/en/audio/amplifiers/2x3w-stereo-audio-amplifier-mini-5v-pam8403-volume-control-v2 - 5v bluetooth module that is compatible with the PAM module (I used https://www.icstation.com/mobile/audio-module-bluetooth-compatible-receiver-universal-audio-module-p-12506.html) - 2x 2 inch full range speaker https://nl.aliexpress.com/item/1005004819270926.html?spm=a2g0o.order_list.order_list_main.25.59e879d25uR6u2&gatewayAdapt=glo2nld - 18650 battery with holder - an USB-c styled charger board with protection - step-up module to 5v - Speaker cloth to decorate the front of the speaker How to put it together: There are 3 parts. - The faceplate is where everything is connected to. - The ring fits around the inner ring of the front and can be used to secure the cloth around the front. Use glue to fix the cloth and the ring in place - The inlay for amplifier and usb-c power fits on the front. To get it in place you need to cut a small hole through the cloth and glue the part on top of it. It will fit snug in the hole. - only after securing the parts and the cloth you can start assembly on the electronics You want to create the whole speaker?
