Nokia recently announced its plans to purchase Symbian and formed the Symbian Foundation with the intention opening the software platform over the next two years. Symbian is already present on 60% of all cellphones in the world. With such a massive install base, open source Symbian has a much better chance of taking off than platforms like Android, which are starting on the ground floor.

Nokia Color LCD Flickr Frame
Tinkerlog got their hands on a color LCD from SparkFun and set it up to receive images from Flickr. These color LCDs are 128×128 pixel and the include a breakout board with a separate power supply for the backlight. Communication is via a three wire SPI bus plus a reset line. [Alex] used an ATmega48 for control, which is connected to the computer using an RS232 to USB converter. The wiring schematic is here.
For the software side of things, he adapted Sparkfun’s example ATmega8 code for the microcontroller (he couldn’t get the Arduino code to work). Beej’s Python Flickr API was used to grab the images. The Python Imaging Library converted them, and finally, they were sent to the display using pySerial. SparkFun has been offering these displays for quite some time; it’s good to see a quality writeup of one in use.

Ultraportable Laser Graffiti?
[Sittiphol Phanvilai]’s multitouch screen project was posted a couple different places today. It uses the Nokia N95 to track light pens and draws the resulting paths on the video output. We immediately saw the applications for this in laser tagging. Right now if you want to do laser tagging you need to haul a laptop with you in addition to the projector. With some modification to the NeuScreen software you could replace the laptop with just cellphone plugged directly into the projector.
Nokia 1100 LCD PIC Controller Interface
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.
This Week In (our) History
Time to look way back into the Hackaday archives, well back to 2005 at least. This is a new feature to follow up and revisit some of our favorite projects of the past. Our first installment includes the week of May 24-31 2005.
Pictured above we see one of the amazing cable braiding machines from UK based Cobra Machinery. This link was found on a post about creating your own high end speaker wires from cat5 cable. At the time we hoped to find a DIY braiding machine. No such luck today but we did come across and interesting site in the process. diyAudoProjects has a ton of great how to guides for all things audio. They even have a few walkthroughs for creating your own speaker wires.
We looked at the robotic dexterous hand from The Shadow Robot Company. Browsing through their high rez image gallery its pretty clear to see the product has been progressing nicely: 24 degrees of freedom complete with force feedback and a GPL based software package.
Three years ago we covered the Nokia 770 internet appliance and it’s upcoming SDK. The device has now been replaced by the Nokia N810 (pictured on the right). However, open source support from Nokia has continued to develop. We found a blog from software developer Ari Jaaksi where he talks about Nokia’s involvement in the community. Recently he discussed the latest news from MAEMO, the platform used for open source development of Nokia internet tablets and other Linux-based devices.
