Yes, I'm planning to make a wireless, Bluetooth and rechargeable version. I'll buy online a USB Bluetooth audio receiver and a Li-ion rechargeable battery with it's charging circuit but I'm still not sure if it's gonna fit in an altoids tin.

Hi! Yes it's exactly the same parts and schematic just replace the USB connector for a 9 volt battery clip so you can easily connect your 9 volt battery and change it when necessary (also it's a good idea to use a rechargeable 9 volt battery)
Thanks! Don't worry it's really simple the positive of the USB connector goes to the middle pin of your switch and then solder a wire from the other pin of your switch to the positive of your circuit board. I'll let you a picture so you could identify which pins to use of the USB connector and in the 3.5mm audio jack you'll only choose one (left or right) and ground because it's a monophonic audio speaker if you want to make it stereo you need to duplicate the circuit amplifier.
Thank you so much! Haha well about that drill I found it useful for this project because I powered it with my bench power supply with different voltage to adjust the speed because my drill has no variable speed. My plan is to use this DC motor to make a mini bench drill press. I only remove the metal part of a electrical connector (picture 1) and use it as chuck drill bit but probably I'll buy a propper one online later (picture 2).
The sound is actually pretty good! You should try it and please share a photo in the comments. Thanks!

Thanks! I bought the components in my local electronic store I spent no more than $5 dollars.
Thank you so much! It 's a very cheap project I spent no more than $5 dollars. If you build your own I would love to see a photo. Thanks
