Sound Module for Thermal Detonator?

I picked up one of Wannawanga’s bunker bombs and I want to add a sound module to it that sounds like the thermal detonator. Anyone gots?
 
Not sure on where to get the sound file, but you can convert copy right free YouTube videos to mp3, for the module you could go with arduino or for a cheap option search greeting card or music box models, they take a little wiring but normally cost under $20
 
There use to be a kit on etsy… I can’t find it right now. But I’ll keep my eyes open
 
Yeah a kit would be awesome. I’m not the best with cobbling together electronics.
I’ve been checking monthly see if it ever reappears on Etsy.. it was a nice little plug and play electronics kit with lights and sounds
 
Get yourself a DY-SV17F module (available on places like Aliexpress). You can upload files such as wav or mp3 to the board using its usb port. Its capable of driving a speaker directly with its on board amp. More than enough for a small proper like the TD.

It has several different modes of operation. While its commonly used connected to something like an arduino to control it, so you can play back LOTS of different sounds it has a few stand along modes. However you can use Standalone Mode zero or stand alone mode 1. In those modes specific pins on the module when triggered via a switch play back specific sounds. So no micro needed.

You don't need to be a genius to use these, there are instructions here DY-SV17F/DY-SV17F module functions introduction.pdf at master · smoluks/DY-SV17F and the rest of the documentation is in the repository GitHub - smoluks/DY-SV17F: DY-SV17F (DY1703A) docs.

Essentially you need a ref 10K resistors to set the mode and a few more for pull ups on the input pins and then you can connect 1-8 switches up to play sounds 1-8.
 
Thank you Neophyl. I’ll take some time to read up on the info. Hopefully it’s not too complicated. In addition I’m sure I’ll need to get a different switch than the one provided with the prop since the one that came with the kit is a potentiometer and should be replaced with an on/off twist type.
 
If you want a real kit, perhaps:

I guess depends on how much you want to do?

I do Arduino based stuff.. and can use a DFPlayer board (which can also be used by itself/without an Arduino)... can help if you want.
