Christmas isn't the only holiday that can be improved by paper clips. At Easter time, they can be recruited into service for dyeing eggs. Twist a paper clip into a spoon-like shape with a base big enough to keep an egg stable, and then use it to dip the eggs into the dye. No more worrying about staining your fingers!

Paper clips can double as temporary hangers for lightweight items, such as strings of decorative lights or small picture frames. After securing each object to a paper clip, attach the clips to a string and use tape or hooks to display the collection on the wall.

Tailoring for loudspeaker selection has cascading effects through the rest of the system. For best sound, they will need matching audio amplifier modules, which will have their own power requirements, which dictates battery performance, and so on. Catering to these desires, components are excluded from the tightly integrated mystery black boxes. Fortunately for hardware hackers, such an architecture also makes components easy to reuse:
Once the circuit board has been extracted, the Bluetooth interface module should immediately stand out as the most sophisticated component sitting close to an antenna. A search for ATS2823 confirmed it is a module designed and sold for integration into Bluetooth audio products. Its MIPS M4K core and associated flash storage could be a promising start for firmware hacking, but the point of this example is to demonstrate how to hack a speaker utilizing existing firmware. So we will leave the module as-is.
The power budget for our hack would be constrained by power figures for those two components. Most microcontrollers consume maximum power during bootup. So as long as the audio source stays quiet during this time, we would have a little extra power to support boot. Somewhere between the regulator and the amplifier is also the best place to tap power. It allows us to piggyback on the existing power management circuit that shuts down the amplifier when entering low power mode, cutting power to our hack at the same time.
A few pieces of internal plastic reinforcements for ruggedness were cut away to create enough volume for an Arduino Nano inside this enclosure. It is no longer quite as rugged, but now it is far more interesting as a platform for sound hacks. To conclude this proof of concept, the Arduino Nano is using the Mozzi audio library to play the classic Wilhelm scream whenever our repurposed button is pressed.
I recently hacked up a bluetooth speaker when I discovered it was only mono output. It had stereo speakers and a passive sub, but mono sound all the way through.When I needed an external speaker for my 2-meter amateur radio I pulled the speaker apart and discovered the drivers were 3-ohms, so I did the logical thing and connected them in series for 6 ohms.I lopped off the 3.5mm stereo plug from one end of the included cable and wired it direct.I ditched the PCB and kept the lithium battery, as it has a protection circuit in it, but added a small ferrite inside to help mitigate RF.I blocked off the holes in the enclosure and plugged it in!Nice!I tried it on my HF rig and it is great there too.I remain impressed with the warm tones I get from this dumb hacked up little speaker. It is very clear and not bright at all, which is preferable for a communications speaker that is subjected to static and noise. 2ff7e9595c
