Bend all audio files to your will with the Adafruit Music Maker shield for Arduino! This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM). It can also be used to record audio in both PCM (WAV) and compressed Ogg Vorbis. You can do all sorts of stuff with the audio as well such as adjusting bass, treble, and volume digitally. All this functionality is implemented in a light-weight SPI interface so that any Arduino can play audio from an SD card. There's also a special MIDI mode that you can boot the chip into that will read 'classic' 31250Kbaud MIDI data from an Arduino pin and act like a synth/drum machine - there are dozens of built-in drum and sample effects! But the chip is a pain to solder, and needs a lot of extras. That's why we spun up the best shield, perfect for use with any Arduino Uno, Leonardo or Mega. This version of the shield includes an onboard 3W/channel stereo audio amplifier that can drive 4 or 8 ohm speakers.

It's the same amplifier as in our TS2012 breakout, a great class D amplifier that sounds good and is power-conscious for portable/battery usage. Volume control is handled by the VS1053 chip. We also have a version without an amplifier, when only line/headphone out is required. We believe this is the best MP3 playing shield you can get, and at a great price too. Here are some specs: Features the VS1053B codec chip - decodes Ogg Vorbis, MP3/MP2/MP1, MP4, AAC, WMA, FLAC, WAV/PCM, MIDI. Encodes Ogg or WAV/PCM Stereo audio out with proper audio filter caps and ground reference so it can be safely connected directly to headphones, a stereo system or other powered speakers 7 extra GPIO's that can be written or read through the Arduino Library for reading buttons or lighting LEDs MicroSD card socket, for any FAT16/FAT32 formatted SD card from 64Mb or greater. Full 3.3/5V level shifting for SD and MP3 chipsets Works with Arduino Uno, Mega, or Leonardo Built in MIDI synth/drum machine with dozens of instruments

Plenty of optional breakouts for pins like the card-detect and microphone input Each order comes with one fully-assembled and tested shield, 2 2-pin terminal blocks, a stick of 0.1" male header and 2x3 female header for the ICSP connection. Some light soldering is required to attach the through-hole headers to the PCB for plugging into the Arduino as well as the terminal blocks for the speakers. Speakers, $1 headphones, SD card and Arduino not included! We're wrapping up the full tutorial with photos of the shield, but for now we have a detailed tutorial with lots of information about the VS1053 as well as instructions for how to use our Arduino library that will get you playing sound effects in under 30 minutesecho 755 backpack blower /officeworks and the youtube channelf-stop loka ul backpack

Free running is all very well, but we've all got different goals and circumstances. Some run to lose weight, others to boost their aerobic fitness, while speed is the top priority of the more experienced.Either way, there are gadgets that can help you get through the run - from tiny MP3 players, wireless headphones and the latest in running-centric trainers, armbands and backpacks - to those that help you monitor your progress. Think activity trackers, GPS watches and heart rate monitors.strange phlogistinator backpackDon't load yourself necessarily with gadgetry, but instead choose wisely and concentrate on that one product that will motivate you, and keep you on track to achieve your goals. backpack nepal pantipHere are some of the best running gadgets around, that you might like to buy.best diaper bags lucie's list

Echewing GPS watches and activity tracker armbands for a free app such as RunKeeper, Endomondo Sports Tracker or MapMyRun is fine, but where will you put your phone? A downright awkward gadget to carry while on a trail, Griffin has come up with a simple armband that keeps a smartphone dry and out of the way.An ultra-lightweight nylon band that easily adjusts in diameter, its moisture wicking claims are less impressive than its ability to stay in place. Some won't like the restrictive feeling on their upper arm, but there's no doubting its usefulness. therapy nala backpackAs well as easily trailing headphones through a t-shirt sleeve, there's a port for connecting the Adidas miCoach Connect heart rate monitor - hence the otherwise irrelevant branding tie-up.But our favourite feature? A tiny key holder that snaffles away that essential - though irritating - running companion.Though boasting a rather odd design, it's good to see a running-specific pair of earphones.

The sweat and water-resistant - and even washable - Sennheiser Adidas PMX 685i Sports neckband headset is worn across the back of the head, thereby avoiding the back-and-forth of a headband, something that automatically makes then suited only to running.It's not just about fit. The actual tips of the earphones take a slight step back to avoid blocking out all noise - crucial if you're running along roads - though still manage to deliver full, bassy sonics.Crucially, there's a cable clip for clothes, and an in-line remote control on the audio cable that operates volume and navigation and enables you to answer phone calls on the move.Probably the most versatile - as well as the tiniest - backpack we've ever used, the Berghaus Limpet 10+ is ideal for trail running. It's made from a reflective waterproof fabric and sits snugly on a back, thanks not only to the shoulder straps, a chest fastener and waist straps (rare at this small size), but also to mottled foam pads that create some airflow in the centre, thereby reducing sweaty back syndrome.
