I made Franken - Bluetooth speakers. Works better than I thought. One 3rd party ryobi battery is enough for a festival week. The second Bosh lawnmower battery adaptor works fine too.
A couple years ago I got an electric lawnmower super cheap. I only discovered earlier this summer the lawnmower and accompanying weed whacker were being discontinued, and if they break in ways I can’t fix, I’ll have a 60v, 5 amp battery to recycle play with.
It hasn’t occurred to me to reuse the battery for some other fun project. There will be shenanigans.
Oh my, you’re who I want to talk to. I have been thinking about making a speaker probably for the opposite reason you did. I want it to be quiet. Quiet as a little mouse. Do you mind guiding me towards your method? Because I am just at the beginnings, but I was wondering if the hardware does the work, or if you get the fixings and then load the hardware up with something open-source. So if you’ve got the time, please let me know!
Ah, I was seeing it as some kind of project in wait and figured I could get some advice from someone who’s been there. I don’t actually have a speaker system of any sort currently. I just wanted to make one for when I did the dishes or take showers. But I really dislike bass so I figured putting together a little 3 watter or something small would be fun and interesting. I also didn’t realize you could just add a resistor to dampen sound but it makes a lot of sense. I haven’t done anything with electronics in a long time. But I figured no better time than today to pick something back up. Ty either way, and keep on keeping on =)
I’m not the person you replied to in the first place, I’m sure they have a lot more to say than my simple advice
The volume of a sound is its amplitude, which correlates to its kinetic energy. Kinetic energy in a sound comes from the electrical energy in the speaker. You can lower electrical energy with a resistor.

What amp you use? Is it stereo?
Love it!
I still had a Tda7492p board laying around. That’s a stereo Bluetooth 4.0 board with 2x50W (8-25V).

Also GJ on the frankenspeaker!
Just throw a resistor on it to make it quieter.
