[Grissini] hasn’t had the best of luck when it comes to personal audio players. He estimates that he’s gone through about half a dozen iProducts/iKnockoffs over the years, which ultimately adds up to a lot of money poured right down the drain. Rather than lay down his cold hard cash for yet another music player that would succumb to a dead battery or cracked screen, [Grissini] decided that he would be better off if he built one himself.
His Orange mePod isn’t exactly the most attractive or sleekest music player out there, but [Grissini] says it works like a charm. An Arduino Uno powers the device, and he uses an Adafruit Wave Shield to handle the audio playback. Power is supplied via 4AA batteries which keep the tunes going for a reasonable amount of time, and afford him the ability to swap them out for recharging without much fuss.
The player was encased with some leftover cardboard and wrapped in bright orange duct tape, before being mounted on [Grissini’s] belt. He says he gets plenty of looks when he’s out and about, which you would expect from such a unique design.
Stick around to see a quick video of the audio player in action.

It’s less than 5 days away from Halloween and the projects to scare small children are pouring in. [Noel] sent in his robotic Halloween mask he’s been working on, and the only way his build could be any better is by placing it underneath a child’s bed.
[Noel] took the mask he used last year and stuffed a few styrofoam craft balls inside to ‘fill it up.’ Two LEDs and a PIR sensor were fitted into the eyes of the mask and a few more electronics added to the brain. A servo was fitted to the base of the project to turn the head left and right.
The build uses a Gizduino Arduino clone with an Adafruit Wave shield. After a little bit of wiring up the LEDs, PIR sensor and neck servo, [Noel] had a bit of coding ahead of him. He ran into a problem with the WaveHC and Servo libraries because they both used the same timer. After finding a another software-based servo libraries, he had a reasonably terrifying project to put in front of a bowl of candy.
Check out the video below for a demo of [Noel]’s work.

If you’re trying to lose some weight, [Grissini] has got the just the thing you need!
He recently tweaked his refrigerator to throw out insults each time its opened, though not for his own physical well-being. While we imagine that an abusive refrigerator would help curb your appetite for late night snacks, [Grissini] makes no bones about the fact that he simply wants to effortlessly and automatically troll his roommates.
The device is pretty simple, consisting of an Arduino and an Adafruit wave shield stuffed inside a styrofoam coffee cup. A photocell is used to detect when the refrigerator door has been opened, triggering the Arduino to play a sound bite from the on-board SD card. [Grissini] even spent a good chunk of time working with a text to speech engine in order to create a customized list of insults that point out his friends’ idiosyncrasies – what a guy!

A few weeks back we ran a piece about the convergence of making and baking in an attempt to create a cake festooned with working LEDs. The moral was that not every creative idea ends in victory, but we applauded the spirit it takes to post one’s goofs for the whole internet to see and to learn from.
[Craig]’s LED matrix proved unreliable…and the underlying cake didn’t fare much better, resembling that charred lump in the toaster oven in Time Bandits. The cakes-with-lights meme might have died right there if not for a fluke of association…

In our hands-on review of the Digilent chipKIT Uno32, we posed the question of what the lasting appeal might be for a 32-bit Arduino work-alike. We felt it needed some novel applications exploiting its special features…not just the same old Arduino sketches with MOAR BITS. After the fractal demo, we’ve hit upon something unique and fun…

Last Friday, Friday we caught wind of [gvillenave]’s running accessory inspired by Rebecca Black, and we we we so excited, we so excited to bring this to you on Saturday, which comes after Friday.
[gvillenave] came up with the idea of using a song on the annoyance level of “Friday” to encourage a runner into keeping up a good pace. The concept is simple: if the wearer is running fast, the song will speed up. If the wearer is slowing down, the song will slow down and extend the agony.
The build uses an Arduino and [ladyada]’s wave shield coupled to an accelerometer. [gvillenave] included the code, and also wired up some LEDs to a pair of sunglasses that blink more often as the runner’s speed increases. The wave shield has a 3.5mm jack for headphones, but [gvillenave] graciously wired a speaker in, “so that you can annoy people around you, and not just yourself.” All this is packaged in a very nice 3D printed enclosure making for a great looking project.
There’s no word on the effectiveness of the negative reinforcement aspect of [gvillenave]’s build, but we suspect it will help her get down to the bus stop a little faster every morning.
As many of you are probably aware, Portal 2 was released last week, and gamers have been going crazy over it. Over the years, people have constructed replicas of their favorite in-game items and “characters”, including portal guns, companion cubes, and turrets.
After playing Portal 2 for a bit, [Jonathan] wanted a turret of his own quite badly. Rather than construct it from hard plastics and resins however, he decided he wanted to construct a cuddly turret that talked.
With the assistance of his friend [Leigh Nunan], he is now the proud owner of a plushie turret. It’s a bit smaller than you might expect, but it is packed full of turret personality. The plushie plays audio from the game, can sense motion near its face, detect if it has been tipped over, and also knows when it has been picked up. [Jonathan] added all of these features by stuffing an Arduino inside the turret, along with a wave shield for playing sounds. Proximity and motion sensing are provided via a trio of different sensors, enabling the turret to behave in the same way its in-game brethren do (minus the machine guns).
It really is a neat little toy, one we would no doubt be glad to have around. Keep reading to see a short video of his plushie turret in action.
