This clock radio plays tunes from Minecraft and it’s decorated to look just like a creeper head. In the game mob heads are available as decoration and [Young_Maker] liked to spice up his virtual bedside table with a creeper head. But we think it looks just as good in its physical form.

The main part of the clock is an Arduino with a character LCD screen. A DS1307 real-time clock makes sure the device is accurate. We called this a clock radio in the title of the post, but it’s more of a clock MP3 player. The uMp3 board is used to play random music from the game. We would categorize the soundtrack as minimalism, which is a reasonable way to gently wake in the morning. But if time runs out the boom of an exploding creeper is played to make sure you’re not late for work.

We’ve embedded [Young_Maker's] demo video after the jump.

[IgorAraujo] has pubblihed another interesting project about robot and Arduino. This time it involves a camera and a bluetooth module.

Appointed to be able to develop a robot communication activity and locomotion guided control with several purposes: conference distance, safety inspection and access to local human presence will unaviable. The intention is to promote environmental inspection, receiving and sending information (image and voice) as well as allow for the visualization of environment and the sensor signals to control the movement of the robot using the Arduino.

As usually, you can find more on his [website] , full post with videos and pictures, thanks for submit again!

This a screenshot taken from [Pierre's] demonstration of an electric guitar effects pedal combined with DSP and Pure Data. He pulls this off by connecting the guitar directly to the computer, then feeds the computer’s audio output to the guitar amp.

The foot controls include a pedal and eight buttons, all monitored by an Arduino. Pure Data, a visual programming language, interprets the input coming from the Arduino over USB and alters the incoming audio using digital signal processing. [Pierre] manages the audio connection using the JACK Audio Connection Kit software package.

In the video after the break he’s using a laptop for most of the work, but he has also managed to pull this off with a Raspberry Pi. There’s no audio input on the RPi board, but he’s been using a USB sound card anyway. The other USB port connects the Arduino and he’s in business.

[Thanks Walter]

E’ stato appena pubblicato il trailer del documentario che Wired Italia ha realizzato su Arduino. Il video per intero verrà rilasciato la prossima settimana.

Hello LMR,

This is one of my robots that I have been working on for a while. I have'nt posted it yet because I wanted to make sure I have a lot done. I use the lynxmotion A4WD1 as the base.

Head to head video game action can’t even compare to this use of a coin-op Sega Rally game to race actual RC vehicles. Take a close look at those screens and you’ll see there are no computer graphics, just a feed for a camera on each of the toy cars.

The project was conceived for the Sapo Codebits VI conference in Portugal. The arcade cabinets had their controls connected to an Arduino, but getting video up and running wasn’t nearly as easy. After fruitless attempts to get the original CRTs to work the team ended up replacing them with functioning CRT units of the same size. The cars themselves have two camera, one on top of the vehicle’s cab and one mounted on a boom for a perspective that was above and behind the vehicle. The drivers can switch between either view. The cars were set loose in the room serving as the event’s retro gaming area and players were free to race each other wherever they pleased. Don’t miss the video clip after the break which shows off all of the fun.

This is my version of the "start here" robot. For me this was a programming exercise. I had written an obstacle avoiding sketch for my Rover 5. It worked but I was never really happy with it. Most code that I've seen online uses lots of delays in the code. Some time ago I swore to myself to never use the delay function in void loop ever again. There are various reasons for it, once you start writing more advanced code the delay function can cause lots of trouble. I also use a library (RF24network) in another project where I can not use the delay function.

[Rodrigo] has been working with Arduino for some time now, but always thought it lacked some features which advanced users would really find useful. He decided to devote some free time to fixing the problem and ended up coding an Arduino IDE for more advanced users. A screenshot of his work — called MariaMole — can be seen above. It is obviously different from the standard IDE, bot not so much as to scare off new users.

This is meant to complement the original IDE, so it actually uses those configuration settings as dependencies. Once running, the program allows you to have multiple projects open at once. These are managed with the tree in the left hand column and a series of tabs along the top of the code window. When it comes time to compile and load the sketch you can click one button like normal, or use the program to fine tune your compiler flags, libraries includes, and the like. It also allows for interaction through one or more serial terminal windows. We haven’t tried it ourselves, so please leave a comment with your thoughts after having given it a go.

Can anyone argue against this being the least-secure hotel room lock on the market? Regular readers will recognize it as an Onity key card lock. A few months back a glaring flaw in the security was exposed that allows these locks to be opened electronically in less than a second. So we are not surprised to hear that a series of hotel room robberies in Houston are suspected to have been performed using this technique.

The image above is from a demonstration video we saw back in October. That hack used an Arduino-compatible chip inside of a dry erase marker as an end-run around the lock’s electronics. It reinforced the warning sound by [Cody Brocious] when he presented the exploit at this year’s Blackhat conference. The barrel jack on the outside of the door lock doubles as a 1-wire communications port and that is how an attacker can gain access. Investigators can find no other means of entry for these thefts.

We applaud one of the victims in this story. At the end of the article she is asked if the information about the Onity flaw should have been kept secret. She said that if there’s a vulnerability that’s not being fixed people have a right to know about it. Bravo [Janet Wolf]!

[Thanks Andrew]

Here we have this submission from [IgorAraujo] about how to use an Arduino as PID.

A proportional integral derivative controller (PID controller) is a common method of controlling robots. PID theory will help you design a better control equation for your robot.

On his [website] there are more pictures, videos and a detailed description, but all in Portuguese.
