Cellphone Operated Robot

cell_bot

If you can get through the cell phone text speak, you’ll probably enjoy this cool tutorial on how to build a cell phone controlled robot. This bot decodes the key tones, similar to the automated phone systems we’ve all experienced. It uses a chip called a MT8870 DTMF decoder to translate the signal for the Atmega 16 controller. The circuit diagram is pretty hard to read, maybe we missed a downloadable one somewhere. The source code is available.

It would be nice to get some feedback from the robot, so you aren’t driving it completely blind. This is similar to the Lego cell phone rover that we showed you before.  Next, he should make it recognize voice commands.

IPhone Controlled Dog Treat Dispenser

[Stephen Myers] has been toying around with some beta ioBridge hardware. He decided to build a remote control dog treat dispenser. ioBridge‘s hardware is built specifically to make web enabling projects easy. The main controller board has four I/O channels that speak to addon modules. It has an ethernet port on the main board and an easy to configure website.

[Stephen] used a servo addon board for his project. The dispenser is built from a scrap CD spindle attached to a servo. He can issue commands from his iPhone, which shows live video of the kennel. He’ll be building several other automation projects based on this system.

Inside Nokia’s Hardware Damage Labs

Like everybody, we sometimes get a little frustrated with our cellphones. Probably one of the most annoying things is when we drop our phones once and they stop working. At Nokia’s hardware damage labs in San Diego, they physically test their phones for extreme uses. They test things like flip tension, water resistance, and even UV resistance. Recently, the folks over at MobileCrunch were given a tour of these labs and were nice enough to post an in-depth article about what they saw. In addition to the impact testing video above, there are many more videos posted that demonstrate the tests they perform.

IPhone Linux

Embedded above is a demo video of an iPhone running a Linux 2.6 kernel. The iphone-dev team has created a new bootloader called OpeniBoot. The bootloader lets you boot into a Linux console, which you can talk to over a USB serial device. They’ve got busybox working, but there is no touchscreen support yet. The instructions are not that difficult and include how to back up your settings. It works on first and second gen iPhones and first gen iPod Touch. This is a very early port, but the future is wide open… Android iPhone?

DIY Cardboard IPhone Dock

While the iPhone 3G included several new features that its predecessor lacked, one thing it did not include was a dock. Instead of shelling out $30 to buy Apple’s iPhone 3G dock, [Roland] and the folks at Geeky-Gadgets.com decided to design their own cardboard iPhone dock. While this doesn’t include any fancy features like dock connectors or audio line-outs, it looks like a quick and budget friendly way to give your iPhone 3G a place to charge and sync.

BlackBerry Storm Click Screen Teardown

RIM has decided to venture into the touchscreen phone market with the new BlackBerry Storm. Unlike other companies’ offerings, the Storm has a touchscreen that clicks when you press it. phoneWreck disassembled the Storm to see what magic was involved in the device. There’s not much too it, it’s just a big button. pW notes that the entire phone board is very compact mostly due to RIM using Qualcomm’s latest MSM7600 chip. Items like bluetooth, GPS, and USB are all included in the processor instead of appearing on the board as discrete components.

phoneWreck recently launched and promises many future teardowns. They’ll be adding to their archive which already includes the Motorola Krave and the venerable Nokia N95. We’ll definitely be watching for their future releases.

IPhone Jailbreaks Updated For 2.2 Release

Working as quick as ever, the iphone-dev team have updated the PwnageTool and QuickPwn to work with the new iPhone 2.2 firmware update. The trouble with the new firmware is that it updates the baseband of the phone, which could potentially undo any progress made towards an iPhone 3G unlock in the future. If you don’t care about that, you can use QuickPwn to jailbreak your phone after the upgrade, so you can run any app you want. If a future unlock is important to you, use the PwnageTool to strip the baseband update out of the firmware update.
