1. DIY Multi-Room Wireless Music Remote

   
   With the help of some external hardware and a handheld wireless device such as an iPhone or iPod touch, you can build your own wireless music remote. It’s a bit spendy if you don’t already have an Iphone/iTouch and a router, but there’s a step by step tutorial to guide you through the setup build.

2. DIY iPhone Controlled Car (Complete Control)

   These guys took an iPhone and using a special app, the onboard GPS and Wifi along with some serious modding they managed to make a life size R/C car. I bet it was difficult to drive using the six-axis in the iPhone but it’s still a great mod. Learn how it was done in an upcoming post. Subscribe so you don’t miss it.

3. iPhone Controlled Mazda (without gas and break)

   By tapping into his car’s onboard wifi and diagnostic systems, this hacker can control his car from anywhere in the world.  He’s able to start the engine, pop the trunk, lock/unlock, and view all vehicle diagnostics from his iPhone. As seen in the video, electronic controls are housed in the trunk along with an Arduino to help process commands.

4. How to View your Webcam on your iTouch or iPhone

5. Build a Solar-powered iPhone Charger

   

   How many times has your cell phone died in the middle of the day because of its lousy battery life? You have several options: you could recharge via wall socket, via USB, through an external battery or the green way, with a DIY solar iPhone charger. Don’t forget to pick up any needed supplies for this build (including solar panels) at our store!

6. Make a Laser Matrix Projector for the iPhone

   
   The idea is to add some kind of projector capability to mobile phone (e.g. iPhone) that isn’t too complex or expensive. Instead of using an expensive mini projector, I decided to use lasers instead to any bitmap font using a matrix of laser points, which is controlled by iPhone.

7. How to: iPhone as a Wireless Router for your Laptop

   Transform your iPhone into a wireless router, allowing you to connect your wifi deprived laptop to the internet anywhere phone service is available. It’s also perfect when you’re browsing the web but the small screen is too cramped. Now you can easily switch over to your laptop for a larger viewing window.

8. RC Car Controlled Via the Web

   

   Strap on a standard Linksys router to an RC car and you can wirelessly control it through the web from up to 1640 feet away. It’s also equipt with a webcam and operates through a brain comprised of PIC microcontrollers or the Arduino’s ATmega168. The in depth tutorial will guide you through the build.

9. Home Automation Using the iPhone and X10

   Like most people, we’re huge fans of home automation. We’ve even covered quite a few ways people have used Twitter to automate your home. This time, however, we’ll be automating our homes by managing SmartHome’s X10 home automation modules using the iPhone.

10. The Rockband Robot iPhone.

    This guy obviously wanted to break a world record in Rockband because he built a robot to attach to his iPhone that plays it perfectly for him. It works by light sensors telling the prosthetic fingers when a note is coming up and driving a motor to press the screen and thus play the note.

You can actually control this robotic lawn mower by using the Wiimote’s accelerometer. Its creator says the concept could also be implemented on a range of different devices – you could actually take your grandmother for a walk by simply tilting the Wiimote, although she might not be very happy about it (brilliant concept though).

It can also be used on ‘automatic’ mode – walk the device to set a perimeter then let the GPS attached mow the lawn automatically without any effort on your part.� Good thing too since it moves so slow.

Here are some other cool projects that use the Wiimote:

• Fantastic Real Time Pan and Tilt Camera
• Foldable Display Tracking Using Wiimote
• Auto-aiming USB Missle Launcher
