Some LMR bots doing standup and improv comedy...

Just got back from SXSW, where Ava (http://letsmakerobots.com/node/45195) and Annabelle, a mobile version using Ana's brain ( http://letsmakerobots.com/node/37264) built by some fellow LMR people in Texas (Lukeyes, and others), were on a panel and did standup and improv bits.  Fun stuff for everybody.

Swimming Pool Dance Floor Enlightened With Leds

In a well documented blog entry, [Loren Bufanu] presents a project that lit up a glass dance floor covering a swimming pool with RGB strips. We mentioned a video of his project in a Hackaday links but didn’t have any background information. Now we do.

The project took around 450 meters of RGB strips controlled by two Rainbowduinos and driven by sixty-four power Mosfets, sixty-four bipolar transistors, and a few other components. Running just the white LEDs draws 8 amps of power.

The Rainbowduino is an ATmega328 Arduino compatible board with two MY9221 controllers. Each  controller handles 12 channels of Adaptive Pulse Density Modulation. In other words, it makes the LEDs flash nicely. [Loren] used the Rainbowduino instead of some alternatives because multiple R’duinos can coordinate their activities over I2C.

The software part of the project did not work as well as the hardware. The light patterns were supposed to follow the music being played. A PC software package intended to drive the R’duinos produced just a muddy mess. Some kludges, including screen captures (!), driven by a batch file tamed the unruliness.

It’s been awhile, but a similar disco dance floor, built by [Chris Williamson] but not over a pool, previously caught our attention. [Chris] is a principle in Terror Tech that recently got a mention on Sparkfun.

The video after the break fortunately does not make a big splash, but is still electrifying.

Control the 'GTA V' cellphone with an iPhone, Arduino and a hack

Grand Theft Auto V has a few mobile apps of its own, but one enterprising modder has taken the idea to its natural conclusion: an application that lets you control the in-game cellphone with an iPhone. With the application you can scroll through text messages on-screen, peep your current list of objectives and, among other things, even control the in-game phone's camera. The YouTube video's description (spotted by former Joystiq'r Dave Hinkle) does't offer much by way of details other than it's running on an Arduino Leonardo with an Ethernet shield connected to a PC, sadly.

Ben Heck fashions a pocket computer with an Xbox Chatpad and Arduino Uno

It's great to see Ben Heck focus his efforts of do-gooder projects like that foot-controlled wheelchair, but we'll always have a soft spot for the modfather's more nostalgic undertakings, like this BASIC pocket computer. Heck created the device for the latest episode of his web show, and if you're following along at home, you'll need the Chatpad from an Xbox 360 controller, an Arduino Uno and a LCD display -- a Hitachi HD 44780, in this case. The modder-turned-host is quick to point out that the project's purpose isn't solely nostalgic -- you can also use it to control real world objects, which in the Heck's case means a ghost on a pinball playfield. Check out a video of the invention in action after the break.

Interfacing yor robot to your PC using Gobetwenio (can work with any MCU)

I am currently working on a project where I need to teach my robot to "see" using an ultrasound sensor. In particular it must find and collect drink cans on a playfield and return them to a specific location.

To make the programming easier I wanted to take the sensor output from the robot and display it on the computer as a chart. As I am a terrible programmer I did a quick google search and came up with Gobetwenio.

Fancontroller

Right, back again with an update on my idea for a kick-ass fanctroller.

So far, I've been coding away and right now, I'm up to the point where the actual fan control is implemented (I've already written the LCD-commands, several input functions, a setup and a menu.) But I'm having some problems.
