This is a nice little twist in the speaker; they are light and come in flat pack form which is great for sending to people.

These are made from a thick paper which can then be folded into the cube shape that we relate to as a speaker box.

I doubt if the quality of sound is that brilliant, but it is a great idea though.

I like steam punk stuff, but this is not one of the better ones, but the good thing about it, is the fact that the mp3 unit was actually found on the ground outside a bus station, which means if the designer had not recycled it into this it would have then been added to the land fill.

It is hard to describe something like what Khan wore on his wrist in the second Star Trek movie, but for just an mp3 player isn’t this going a little over the top or maybe not, most of the parts have been recycled too so at least they did not even end in the trash.

This is a pretty cool device, which is handy if you watch DVD’s or listen to music on your laptop.

Arrow, Enter, Back and Page keys to navigate Error! Hyperlink reference not valid. Media Centre and give PowerPoint presentations.
Volume Error! Hyperlink reference not valid. To crank the volume up and down in any Windows Program. E.g. PowerPoint, Windows Media Player, RealPlayer, Power DVD, Winamp…
Media Controls to Play, Pause, Fast Forward and Rewind videos, DVD, live and recorded TV, even music. Eliminate lost remotes by storing it inside your laptop (PCMCIA Slot), that way it is always available when you need it.
The remote protrudes slightly from the slot, making it easy to pull out and use.
Support user custom key setting Support Windows Vista, XP, 2000, ME
Powered by a (CR2025) battery
Dimensions: 85.8 x 54.2 x 5.0mm

There is nothing flashy about this device, but it does a good and useful job, obviously this is not going to be used all of the time, but it will be handy when using the computer for watching media etc.

Priced at a very neat price of $30!

The Apple is so small now that is it quite possible that is can be lost, so the logical thing to do is to build furniture around the iPod, that way it will always be safe and sound.

These sofas are great they look stylish and will go in with any interior design, and yet they have a purpose, this is where the music comes from. There is a little place for the device, and the sound and other features can be controlled by buttons and switches on the furniture itself.

The prices are not too bad; the dearest item is only $399!

Check out the Part 3 of “HOWTO make sounds with Ardunio” and learn to play melody.

Bit-Banging Sound
To bit-bang sound we toggle an output pin at the desired frequency. To play a musical note, we need to use specific frequencies and play the sound for a specific amount of time.

Generating the desired frequency big-bang style means figuring out what the period or cycle time of the desired frequency is. This is easy to calculate, it’s the reciprocal (1/F) of the frequency. As we found in part 2, 1KHz is 1000 cycles per second. So, one cycle takes 1 one-thousandth (1/1000) of a second or 0.001 seconds (1 millisecond). We need to toggle the pin at this rate so we want to keep it low for 1/2 the time then high for 1/2 the time. Therefore we want to set the I/O pin low for 500uS, then high for 500uS and do this over and over for as long as the duration requires.

Here’s a cool audio and video controller DIY using Arduino.

We all know that software is used to track users and what they do, and therefore why should Apple be any different, well it simple really there are a lot people around the world who think that Steve Jobs is god and Apple is his religion of which they all follow.

This is why spying leave all of these folks with a bad taste in their mouths. So how does this work? When you use the iPhone and press the weather application, data is sent along to a web address at Apple and some details too, like the IMEI number etc, this can track where you are and what you are doing at the time.

This could also be used by Apple to find all of those unlocked phones, but users should check out their agreement if they don’t this and see if there is anything on there that will stop this from going on!

This takes you back to when the iPod was just figment of Apples little eye, this steampunk version dates back to the nineteenth century, which must have been when they were designed.

But on a more serious not, these are actually covers, these give an inside look into what an old and ancient iPod would have looked like, but the music may have been a slight probe, back then!

Prices are from $14.95

So, you want to make some sounds with the Arduino you just bought last Friday? Check out uCHobby as they show you how to do some basic stuff with sound and Arduino including how to make “Hello World” sound using a PC speaker.

This is the second in a series of articles about generating sound with an Arduino. The first article covered the various methods available for sound generation with an Arduino. In this article we take a small step; “Hello World” for Arduino sound. We prepare for our future experiments by hooking up a PC or powered speaker so we can hear the Arduino sing.
