DIY Radio Control

Monday, May 14th, 2012

Going to buy a new Wireless Controller for your next Robotics project. Why buy a new one when you can Do-It-Yourself? All you need is an Arduino, an old Joystick with a Gameport (15-pin connector) and a pair of Series 1 xBee Modules.

The explanation of the xBee Configuration and the xBee Packet Description is very well done at the blog.

Transmitter: Joystick + xBee [No additional hardware needed]
Receiver: xBee + Arduino + [your amazing Robot, Car or a Plane!]

The age of the invisible steering wheel

Sunday, May 13th, 2012

A Nintendo Wii-remote along with bluetooth communication and an arduino gives us this magical cart with a wireless steering wheel.

These cool people are staunch DIY-ers and would love to see the community build more such vehicles.

The cart has two motors which use a chain to drive each of the rear wheels. A pair of H-bridge controllers let the Arduino interface with them. It’s also has a Bluetooth module that makes it a snap to pull accelerometer data from the Wii remote. The front end looks like it uses rack and pinion steering, but you won’t find a pinion or a steering column. Instead, a linear actuator is mounted parallel to the rack, moving it back and forth at the command of the Arduino.

The only downside I spot is the Battery life. I am sure that would be worked out too! Till then – Kudos to the inventors! I smell futuristic looking vehicle controls here. :)

Bluetooth communications between Arduino and Android: an introduction

Monday, May 7th, 2012

John Boxall of Tronixstuff has written a very interesting tutorial article on his blog about how to connect any Android-based smartphone with an Arduino board, by means of Seeedstudio’s Bluetooth Bee and a promising, yet simple – open-source Android application, named BlueTerm, which provides RFCOMM/SPP serial communication capabilities.

In this introductory video, John shows how to wirelessly turn on and off Arduino’s digital pin with his setup.

Browser book-marks brought alive using RFID

Saturday, May 5th, 2012

A device that opens the websites using physical world interaction? This is a step closer to the internet of things. Using our beloved Arduino and RFID tags, we can think of a lot many applications of this device!

Too lazy to create your own Arduino + RFID reader? No fear! Arduino internet Gizmo is here.

A detailed Step-by-step making instruction is given here.

What websites are you going to keep as your shortcuts today? :)

The famed @MBTweetFleet tweets using Arduino

Thursday, April 5th, 2012

In case you have been following MBTweetFleet and availing awesome parking spaces, you would be happy to know that the service was made using an Arduino and GPS/GPRS shield.

The cars automatically generated a tweet with GPS data out of every empty parking space they passed. Via Arduino the onboard electronics were connected to a GPS/GPRS-Shield. Tweets were generated with a PHP Relay which sent the GPS-Data. This is how people could find empty parking spaces near them on twitter and even be navigated there by a linked Google map

Easy cross platform configurator for XBee modules

Italian company “moltosenso” has released a free, cross-platform software that allows you to configure all the parameters of your XBee modules. (more…)

Social Fuel For Your Car: Travel With A Little Help From Your Friends

Thursday, February 23rd, 2012

Impressing automotive hacking lets this FIAT car moving by the number of “like” from the Guarana Antarctica Facebook Fan Page. The advertising idea is simple: let the social audience support this Sau Paulo to Salvador trip to reach the Carnivalby commenting / “liking” the page. The onboard Arduino ADK (connected to a tablet and the internet) allows the car going on by a certain amount of meters (apparently one “like” is 10 meters, while each comment lets the car go ahead for 20 meters).

Ball of Dub Keeps Audio in Your Hands

Tuesday, November 1st, 2011

Ball of Dub from LUSTlab on Vimeo.

Accelerometer to Renoise via OSC  to control trippy and dubby sounds.

[Lizzie] from LustLab sent in her Ball of Dub that turns a few accelerometer and a digital audio workstation and turns everything into an aural experience of wubs and dubs. The Ball of Dub can turn just about anything into dubstep, and does so with a fairly interesting user interface.

There isn’t a build log for the Ball of Dub, but  the folks at LustLab did send in a basic overview of her project. Inside the ball, there’s a Razor IMU from Sparkfun that is attached to the ever-popular XBee wireless transceiver. A tiny program on an Arduino calibrates the gyroscope and accelerometer and sends that data to the DAW at 50Hz.

The host computer is running Renoise, a very popular tracker that can accept MIDI and OSC input. A Processing app parses the ball spin, free fall and impact, averages them over a period of time, and pipes that into the OSC input of Renoise. In [Lizzie]‘s video, the ball spin is sent to a low-pass filter on the baseline track, and the average impact is applied to the vocal track.

Arduino, iPod and RFID make beautiful, handicapped-accessible music together

Wednesday, October 5th, 2011

Terrence O’Bien posts a clean music interface (no menus / no buttons)  based on RFID, as previously seen some time ago.

There isn’t actually much new about this awesome DIY project, but it’s the way it brings the various parts together that has us impressed. Designed by Instructables user XenonJohn, with help from software developer David Findlay, the Magic Music Table RFID was designed to let a disable child (or other such handicapped user) select albums to play back from an iPod touch playlist. The iPod is connected to anArduino, which tells the device to start playing a particular track based on a selection made with RFIDcards. The whole setup is built into a coffee table and the RFID tags are sandwiched inside clear plastic blocks with the album art. You can see it in action in the video after the break and, if you’ve got the patience and skill, you can build your own using the directions at the source link.

Retro Pinball Clock Hack

Wednesday, October 5th, 2011

[Alan Amon] posted a cool vintage hack on Instructables, adding GPS-based clock funcionalities to a Bally Wizard pinball.

Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day.  At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.

If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.

Have a look at the “cool features” and “coolest features” in the instructables article
