Nokia LCDs have been a popular choice for hardware projects for quite a while. [Ramandeep] published a how-to on interfacing the 1100 series LCD with a PIC controller. The 1100 features easily soldered contacts and a backlight, making it an good choice for adding an LCD to your project.

Covert IPhone Moleskine Case
Crafting isn’t really our thing, but just last week we were planning on doing this project. Thanks to the how-to singularity: the longer we wait, the more likely someone else will do our dirty work. The instructions are this:
- Cut a hole in a book.
- Stick your phone in that book.
- Let her open the book.
Wired’s write up has about 600 more words if you need clarification. The ebook on the screen is Cory Doctorow’s Little Brother, so expect to see this on BoingBoing… and again when it’s fan translated into Polish. [bre] made a similar hidden compartment book last Fall for Make’s PDFcast.
In all seriousness, we do enjoy the idea of carrying an innocuous little book around that could be doing some covert WiFi scanning, acting as a mobile accesspoint, or live streaming our location to friends. Unfortunately, since it’s an iPhone, most of this isn’t possible yet; you can’t even voice dial from your headset, while leaving the notebook in your pocket. This case also blurs what is considered rude. Most people would be annoyed if you started txting mid conversation, but people taking notes in Moleskines don’t get the same treatment.
Wiping An IPhone (more Thoroughly)
You may be hoping to subsidize the purchase of an iPhone 3G with the sale of your old one, but since you should wipe all your personal data from the old one first, we brought you [Rich Mogull]’s method for wiping all your private data off of an iPhone. The method, which involves overwriting your data with music, is slightly flawed, mainly because of live files that can’t be deleted while the phone’s OS is working and because the OS reserves a portion of the hard drive as unwritable space, which will make it impossible to completely fill it with music.
For those looking to annihilate every scrap of personal information, check out [Jonathan Zdziarski]’s method. It involves restoring the phone as a new phone, then jailbreaking it. Once the user has shell access, umount is used to force the two mount points into read-only mode. Now the partitions can be overwritten with /dev/zero, which should wipe them clean. The phone should then be forced into recovery mode to perform another full system restore, and the process is complete. As [Zdziarski] notes, several iterations of the process with /dev/random should prevent even NAND recovery, but there is an even better way of ensuring full data destruction: “simply take a sledgehammer to the device.” If you are unfamiliar with the command line though, chances are [Rich Mogull]’s method will be easier for you to handle, but don’t blame us if you sell your phone and the Feds get wise to the evidence you left on it.

GSM Remote Control Project
It’s been a while since we’d seen any new SMS/GSM/serial remote interface projects. [Emanuele] sent in his version of a project to do just that. It uses a PIC16F84 and will send or receive commands. A pair of relays provide options for controlling whatever you want to hook it up to. You’ll need a login, but he’s released the full schematics and firmware. He developed this to find uses for old phones, but an alternative is to pick up a cheap calling card cell and dedicate it to a project like this. This seems like a great way to add an out of band alarm system to your house/car/robotic minion.
IControlpad, IPhone Gamepad
[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
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:
- BioWallet – Biometric authentication system that uses iris identification.
- Talkplay – Video and voice message system, see and talk to your friends while on the go.
- 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
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.
