I made an audio thing
(lemmy.world)
0.25mm nozzle, clear PETG, Prusa, 6mm standard headphone jack, upcycled broken bluetooth headphones, three times larger battery, snap fit with no hardware, FreeCAD, 2nd print iteration, listening to it now, no tricks - it holds together firmly and is usable and actually sounds better than the original by a long shot from better headphone drivers I guess or proper soldering, oh and power button built into the flex of the design, OC only posted on Lemmy
I can see that it is an audio thing and details of its make, but what does it do?
It does what Bluetooth headphones do but with regular headphones. More usefully, it is a Bluetooth line-output to plug into an amplifier which is what I am actually working on. This will go into an amplifier that can connect to my laptop and is integrated into my bedside laptop stand (I'm physically disabled so in bed most of the time). I'm working on making several parts of my laptop stand more modular. I want this to be removable to use elsewhere if I want and charged when not in use. It therefore has a use, a place of storage, and is always available.
It’s the guts of a pair of headphones, retrofitted with a battery and audio jack. Consider it a Bluetooth audio receiver and DAC with standard audio output.
Based on the post, I think it already had a LiPo charge unit on the board and they just slapped a higher capacity battery on it? Still hella sweet.
Looks like it receives audio wirelessly and to the headphones.
Audio stuff.
