IControlpad, IPhone Gamepad

May 24, 2008 by 7 Comments

[CraigX] has been dabbling in iPhone accessories lately by adding a gamepad. Called the iControlpad it surrounds the iPhone making it look very PSP like. As anyone who has jailbroken and installed emulators probably knows, without feedback the touch screen based buttons are less than great.

The unit is currently a prototype however there are plans to produce and sell the units. They have received support from Zodttd, an organization that has created iPhone apps like snes4iphone and genesis4iphone. The developers also state they’ll provide source and SDK support. The sparse development blog announces their success using a hacked up SNES controller over the docks serial connector, but they provide absolutely no details.

Google Android Application Challenge Winners

May 23, 2008 by 5 Comments

The Google Android team recently launched a challenge to encourage development for their new cellphone based platform. Part of the first phase was to narrow down the 1,788 submissions to the best 50 application ideas. They’ve posted the complete list of winners on their website and put together a little slide show(PDF) as well. As part of the challenge some $10,000,000 is up for grabs from Google.

We browsed through the list and found a lot of social this and family that; nothing overly exciting honestly. There were a few interesting application ideas in there though:

  1. BioWallet – Biometric authentication system that uses iris identification.
  2. Talkplay – Video and voice message system, see and talk to your friends while on the go.
  3. Writing Pad – A unique way to enter text into your phone where common words are replaced by simple strokes.

The Android platform will probably cause the largest adoption of Linux based cellphones yet. We can’t wait to see what the homebrew community does with the platform and so much development for an unlaunched phone is amazing. Apple seems to go out of their way to lock us out, where this platform couldn’t be more open. With 3G support, WiFi, SQlite, Virtual Machines, GPS and much more what’s not to like.

Have any of you experimented with the Android SDK?

Twittering From The Command Line

May 22, 2008 by 9 Comments
Twitter users often have trouble explaining just exactly what the service is for. The site specifically asks “What are you doing right now?” A simple interface and multiple ways to update means people have started hooking it to different real world objects… objects that aren’t reporting what they had for lunch. After the break, we’ll cover a couple devices that have interfaced Twitter to the real world and how you can update from your command line.

Erase An IPhone Properly

May 20, 2008 by 14 Comments


A fundamental problem with flash memory has just gone mainstream. A detective successfully recovered data from a refurbished iPhone purchased from Apple. Flash memory controllers write to blocks randomly so using standard secure erase techniques are no guarantee that all of the storage space will be written.

[Rich Mogull] has posted a method that should wipe out almost all remnants of your personal data. You start by restoring the iPhone in iTunes and turning off all the syncing options. Next you create 3 playlists large enough to consume all of the phone’s storage space. Sync each playlist in turn and your residual personal data should be obliterated. All that’s left to do is sit back and wonder when the first article about the MacBook Air SSD being impossible to securely erase will be published…

Multitouch Project Roundup

May 20, 2008 by 14 Comments

It seems that ever since Microsoft unveiled the Surface table the concept of multitouch has really started to snow ball. We’ve been fans ever since seeing [Jeff Han]’s original research in this area. Earlier today we looked at a multitouch rear projection TV project but what else is out there? After the break, we’ve got several multitouch projects you might be interested in.

IPhone GPS Module

December 14, 2007 by 22 Comments


The boys over at engadget put this up while I was working it over, but I’m still gonna hit it. [Curt] sent in the iPhone GPS he put together. He’s using a micro-controller to send the ground toggle handshake we mentioned in the iPhone serial tutorial, along with a small NMEA serial GPS module. After the handshake is completed, the controller hands over the serial port to the GPS output. (Since the handshake only needs the ground toggle, I’d guess that the module is connected to the TX/RX lines all the time.) By the way, the GPS looks like this SiRF II board sold by spark fun electronics.
