Story

Overview

Playing funny sounds at random times always amused me. With a smartphone this is an easy task. But what's better than an app? Time to create some hardware to play annoying sounds!

This device is easy to operate and holds place for 16 soundboards, each containing 16 sounds. The soundboard can be choosen by pressing button 1 and 16 simultaneously. Now it's in soundboard selection mode. Simply press the desired soundboard button (1-16) and confirm with the same button.

Also the volume can be adjusted, simply by pressing button 1 and 16 simultaneously. Now it's in volume set mode. Simply press the desired volume button (1-16) and confirm with the same button.

Fabrication time!

Step 1

First, start by printing all the enclosure parts.

While the printer creates all the parts, start assembling the custom PCB and solder the 16 led's for the trellis board.

Custom PCB

First solder the headers on. Then start connecting the Trellis pad, OLED and Amp.

Assembled PCB

please note, this version of the pcb has some wrong text. This is corrected in the supplied design.

Take the enclosure mid part and slide 8 nuts into the nut holders.

Step 2

Now take the enclosure mid and put in the PCB holder. After that you can slide in the speakers and the Oled.

PCB holder, speakers and oled into place

Attach the PCB on the PCB holder using 3 screws and nuts. Then attach the speakers to the amp (in series). After uploading all your sounds to the Audio FX board, you can put this board on the PCB.

Attached PCB and connected Audio FX board

Step 3

Now you can attach the Micro USB connector + cable to the bottom of the enclosure. Also screw the bottom to the mid part of the enclosure. Attach the USB to the feather and slide it into place on the PCB.

Now put the trellis holder on top of the speakers.

Trellis holder

Put the trellis board on top of the trellis holder.

Trellis board

Step 4

Now put the silicone buttons on top of the trellis board. After that you can put the top cover on the enclosure. Secure with 4 screws.

Silicone buttons

Top cover

At the end, put the speaker covers and the feet into place.

Speaker covers and feet

Last but not least, insert the soundboard and audio file names in the code and upload it through the USB connector on the rear side.

Have fun!
