[Hcgilje] threw together a tutorial on using serial communications in iPhone applications. It builds upon the DevDot tutorial which was posted back in 2007. A lot has changed since then; the firmware has come a long way and there are several development tools that now make things a bit easier for you. His examples use Interface Builder and openFrameworks to demonstrate GUI control of an LED and a servo motor. Now go out and design your own peripherals for this popular handset.
[Jeff] and his team completed this iPhone controlled rocket launcher as part of their final project at Georgia Tech. Two servos provide the rotation referenced by an onboard electronic compass, and elevation control for launch. These are interfaced with an eBox 2300 using a few Phidgets boards.
Check out the launch video below. It’s too bad that they went with a commercial solution for servo control rather than building it themselves (especially considering it is an embedded systems class). But it is a nice build none the less. Now they need to add some imaging equipment to the rockets and they’ll be in business.

[ZodTTD] has released a Nintendo 64 emulator for iPhone. It is available (for a price) at the Cydia store and can be installed on jailbroken iPhones. The video shows Wii Remote support as a control interface that uses both buttons and the accelerometer, an addition since we last looked at his work. There is no word about nunchuck functionality, a must if you’re going to try to 100% Mario64.
Using a Wii remote as the controller for iPhone games? Brilliant! We’ve been waiting to see some creative usage of this pairing since we covered it back in August. [ZodTTD] is the person who ported MAME over to the iPhone. Now he’s added support for the Wii remote in Mame4iPhone via the BTstack project. BTstack seeks to add Bluetooth stack functionality to devices that don’t have it or where it is limited (the iPhone).
We’ve embedded video after the break of the WiiMote used to play a MAME game. [ZodTTD] is also the author of nes4iPhone, we hope that’s the next project he will add BTstack support to!
Well no, but [Chris] needed something to remind him when to water the tree. Most folks would use their nifty iPhone to set up a calendar reminder, but why do that when you can purpose a 32 bit microcontroller to do it for you?
To detect a falling water level [Chris] attached a two-pin header to the end of a clothes pin clipped to the side of the tree stand. When the water level is covering the pins it completes a circuit, verified by a measurable current. When the water level drops the mbed microcontroller detects the loss of conductivity and through some creative code sends out an email and SMS reminder.
If you’re in love with your iPhone but not your living things, this will keep that tree kicking until after the new year.

This looks like a fun little project. [Chris] has built a tank that he is controlling using his iPhone. Constructed mainly of off the shelf parts, like an Arduino and an Xbee wireless unit, the tank is controlled via processing. You can see that it is fairly responsive as he changes the speed of the motors. You don’t need an iPhone for this, really to do exactly what he’s doing any multi-touch input would work. You can download the code for it from his site.
We’re a bit curious about the solar charging. How much power does this use? Doesn’t that panel look a bit small? How long does it take to charge?

Why take an iPhone, a slim device that already takes decent photographs and add several macro magnifying lenses? For [Mathijs], simply because he could, But now he can take some awesome macro pictures.
[Bhautik] (maker of the tilt-shift Plungercam) took the concept further. With some more trademark plumbing supplies and a lot of duct tape, secured an interchangeable SLR lense assembly to the back of his iPhone.
Check out some photos from both setups after the break. Continue reading “Double Dose Of IPhone Camera Hacks”
