Hexapod Controlled By Android And IPhone

This video is a blatant example of having too many high-end toys but we love it anyway. [Robert Stephenson] is controlling a rather awesome-looking hexapod via a Bluetooth connection to his HTC Hero. The app allows on-screen selections to decide which portion of the robot will move as a result of accelerometer data from the handheld. The only thing we saw that was missing is a camera feed to the phone.

But this hack doesn’t stop there. The Hero can be used to host a WiFi network while still connected to the hexapod. The second half of the video shows an iPod Touch connecting via WiFi and controlling the bot. Now head on over to the laser cutter to start that hexapod build, and finish up by getting elbow-deep into some Android development.

Androidome: Monome For Android

August 16, 2010 by 10 Comments

[Ewan Hemingway] tipped us off about his new Android app, Androidome. This is the first one he’s turned out after going through our Android development tutorials. It combines an app running on his Android 2.1 device with a computer running Max/MSP 5. The two don’t needed to be tethered, they just need to be on the same wireless network. This won’t be the best solution if you’re doing live performances, as the buttons on the screen end up being quite small. But as you can see after the break, it’s a great way to get into working with the Monome interface and decide if you want to build a dedicated physical version of the tool.

New Nook Says: No Root For You!

August 15, 2010 by 47 Comments

That is a blurry image of a Barnes & Noble Nook eReader stuck in an infinite reboot loop. This is the result of trying to downgrade the firmware to 1.0 in preparation to soft-root the device. So after a few failures the device will recover itself, right? It doesn’t look that way. No problem, don’t you just pop it open and re-write the OS to the SD card inside to do a hardware root? Nope, it looks like the newest hardware revision has replaced that convenient SD card with a memory chip.

For now it’s a brick, but we’re sure there will soon be a way to fix this. A bit of solder, some wires, and a reflash should work much in the same way an EEPROM recovery does. That is, if you have an original image to work with.

So for now, be careful not to attempt to root your nook if the serial number starts with 1003.

DroidX Gets A Custom Recovery Image

August 11, 2010 by 18 Comments

[Birdman] has managed to push a custom recovery image to the DroidX. This previously impossible action opens the doors to all kinds of fun hacking. While you can’t just drop a custom Rom on the phone right now, this is the first step in making that happen. You can find the directions in the post, but they’ve got a while to go before they become as easy as something like a jailbreak.

Android Development 101 – Part 6:Getting Ready For Market!

August 10, 2010 by 25 Comments
In this tutorial we are going to cover packaging one of our applications into an .apk file and getting it ready for the Android Market.  After we have completed this tutorial you should be able to use the tools provided in the AndroidSDK to sign your application, put the application on your phone and install it or send it to the Android Market.  These will be great assets to have if you decide to develop applications that you may want to charge for.  This tutorial will also be a change from the normal ones because it will include little, if any, code.

Android Development 101 – Part 5:DroidDraw & Information Tracker Completed

August 5, 2010 by 5 Comments



In this tutorial we are going to cover completing the Information Tracker using DroidDraw to design the layout of this project. This will give you insight into an alternative to the stock layout manager in the eclipse environment and how DroidDraw functions. DroidDraw can be your best friend when designing Android applications or your worse enemy if you don’t know the layout of the application and how it works. This will show you the basics to this program and how to incorporate it into your development process.  This is significantly easier than the previous post but will teach skills on other programs to help development such as DroidDraw.

Driving With Android

[Elrik] converted an RC car so that it can be controlled with an Android phone. He wisely uses the accelerometer for steering with a button for forward and another for reverse. There’s even control for the headlights. The car itself has had a servo retrofit for steering but it’s the Bluetooth module that catches our eye. It’s a GP-GC021 which you can get your hands on for under $20. It has a serial UART for easy interface with a microcontroller at up to 9600 baud.

Now you can convert over that larger vehicle to use Bluetooth instead of WiFi, just don’t hurt yourself. And if you’re just starting out with writing Android apps, don’t miss our series: Android Development 101.
