[Jeremy] picked up a Vexplorer pretty cheap, and wanted to make it better. He decided that Arduino controls would probably be a nice upgrade. He patched into the controller and installed a nice looking plug to interface with the Arduino. He says the software was custom made as he couldn’t find suitable examples on the net. His software is available for download. We covered a picaxe controlled one in January, but it looks like that site is currently down.
Reader [Joshua] sent in his latest project. using a sonar rangefinder, an Arduino, and some clever programming, he’s made is computer react to his distance from it. As you can see in the video after the jump, he has programmed it to change text size and background color depending on his distance from the screen. While he admits that his implementation doesn’t seem immediately useful, there’s lots of potential there. We can actually think of several uses. What would you use it for?
The Arduino MEGA is official and even more expansive than we originally thought. It has 54 digital i/o pins. 14 of those can be PWM outputs. Along with 16 analog inputs and 4 UARTs. It is even compatable with most shields for the Arduino Duemilanove or Diecimila.

[derektroywest] has posted a detailed step by step breakdown of making a Daft Punk costume. They’ve done a great job, the overall look is very convincing. They include links to where to get each part as well as information on how they pulled it off. The helmets were inspired by the timelapse Daft Punk helmet build. As you can see in the video, they don’t have the entire visor made into a display, but the effect is quite nice, especially because it is multi color.

[kero905] sent in this project he’s working on. It is an open source hardware converter to connect Wii controllers via USB. It uses an Arduino for its brains. It is still in development, the only controllers that work are the nunchuck and the classic. He notes that there are enough extra pins left to adapt to an arcade controller fairly easily. The code is available on the site, as well as a rough parts list.
Evil Mad Scientist Laboratories spotted one of the first images of the Arduino MEGA. The board is based on the ATmega1280 microcontroller, which has 128KB of flash,4KB of RAM, and 4KB of EEPROM. We haven’t seen any official specs yet, but the silkscreen shows 12 PWM connections, 36 Digital I/O, and 16 analog inputs. The post mentions 4 hardware UARTs and an I2C bus as well. No release date yet, but we can assume it’s soon since the hardware was already demoed at ETech.
Related: We added an Arduino category.
While playing with an ATmega168, [Jeff] programmed the RSTDISBL fuse bit. This pretty much makes the chip useless in most cases. [Jeff] didn’t want to give up on it though, so he built a system to program it using the rarely used high voltage parallel programming mode. He used an Arduino, a few lines of code and a few spare parts to make it. After sharing the idea with some fellow programmers, he decided to make an Arduino shield specifically for this purpose. You can use this to reset almost any fuse to rescue a chip. If you are a die hard AVR person and never started using Arduino instead, the STK500 actually has this built in.
