Sounds of Motion

These X-mini speakers have become a great addition to my technology collection.  I wish I could share a video or something that would allow you to appreciate the kind of sounds they kick out.

Small. Durable. Compact. Portable. Versatile.

And about half the size of a can of Coke.

They interconnect using magnets and they can each expand to provide better bass.

Additionally, each speaker has its own battery (which charges off a USB plug), allowing you to use the speakers anywhere you go, like the ocean front, for example.

Mixing Old and New Batteries

Many battery-powered electronic devices come with a warning like this:

BATTERY WARNING:

Do not mix old and new batteries.  Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium) batteries.

One device I noted this warning on was an automatic card-shuffling device. It seemed entirely out of place, since the machine only used ONE nine-volt battery.

Of course, the advice is sound and should generally be followed.  However, in this case I don’t think the warning necessary, as it would be practically impossible to use multiple batteries at once in this device.

According to Duracell, the reason to avoid mixing old and new batteries is that doing so will reduce overall performance and may cause battery leakage or rupture.  If you’re curious, for a more detailed explanation take a visit here.
