SmartLCD makes video for microcontrollers easy

[Rossum] developed a host board that makes it easy to drive a TFT screen using an inexpensive microcontroller. He’s looked around at a bunch of LCD’s that are easy to get your hands on and decided that the iPod Nano 2G screens are the right balance of performance (176×132 TFT) and low cost ($1-$5). They’re not particularly difficult to talk to, but with 22 pins they’re a bit hardware hungry.

He takes us through the signal sniffing he used to figure out the communications process. From there he harness the power of an ARM Cortex M0 processor, which he’s worked with in the past, to drive the screen. His implementation results in a driver board called the SmartLCD that takes care of the screen’s parallel protocol, power, and backlight. From there it’s just four connections and you can use a small microcontroller like the Arduino seen above with ease. See what it can do after the break.

Android on iPhone: New treats

It seems that the iPhone 2g and 3g are the newest phones to get Android 2.2, codenamed Froyo. The process for installing Froyo if you have a jailbroken device seems to get even easier every time, with this revision being as simple as adding a repository, downloading Froyo, and pressing go. Follow the link for a wonderful step by step guide, complete with screenshots to take out all of the guess work. Android on iPhone sure has come a long way since the first time we covered it.

Android on the iPhone

Android, on the iPhone? We’ve covered iPhone Linux before… and if you look back, we mentioned the possibility of porting Android to the iPhone (even way back in 2008!). Well we are proud to announce that The Future is Now! The details are a little slim so far, but the iPhone is seen running a stock Android 1.6 install (Donut), and has support for Wifi, GSM networks, and even uses openiBoot to dual boot to the regular iPhone OS if you aren’t particularly committed. Right now the developers are considering it an Alpha version, and have provided all you need to perform this particular brand of Cult of Apple heresy. One catch though, the developers say that they only have it working on the 2G models, so sorry all you 3G(S) folks (for now). Dont get too down, and keep an eye open, something like this is bound to attract new talent to push the movement.

Anyone out there with a 2G and some free time? We would love to see some users showing off Hackaday on their hacked up iPhone!

iPod Touch 2G jailbreak released

ipod

The iPod Touch 2G jailbreak was first shown in January. It had to be applied every time the iPod was booted. The iphone-dev team just released the 24kpwn LLB patch to allow for a persistent jailbreak. The team had been hanging on to this patch because there was the possibility the exploit could be used on future iPhone versions. Unfortunately, a group started selling the code, so the team was forced to release it for free. iPod owners are certainly happy though. There is a tutorial available for updating a factory reset iPod (backup link). The team will include the patch in future official tools.

UPDATE: [cptfalcon] pointed out a post that covers the technical details of the exploit.
