In this instructible, [wkter] takes us through the process of running a Nokia 3310 LCD display using an ATmega8. This instructible isn’t a beginners project as he assumes you already have a strong understanding of how to work with these components and their programming languages. He is very thorough with information though, providing datasheets, pinout diagrams, and source code. Once you get this down, you could go a little further and make Conway’s game of life.
[Jethomson] worked out a way to use a Nokia USB cable at a USB to Serial cable. He was able to pick up one of these cables for less than $3 delivered. A little probing worked out which conductors go with the appropriate signals and from there he developed a way to protect the 3.3v signal levels with a voltage divider.
It’s not surprising that this works, having seen [Will O’Brien’s] post covering serial communications on Nokia phones. In that post we learned that the Nokia phones are using TTL communications. Once you’ve completed [Jethomson’s] modifications to the cable you can follow his examples for using this in conjunction with an Arduino.
[Miguel A. Vallejo] wanted a portable spectrum analyzer for the 2.4GHz ISM band. No problem, there’s modules for that are easy to interface with a microcontroller and LCD screen. But carrying around a black project box doesn’t exactly scream ‘cool’ so he fit his spectrum analyzer inside of a cell phone. This made a lot of things easier for him; he already had a few old phones, he was able to use both the original battery and the original LCD screen, and a lot of the mounting work is already done for you. The only challenge was to fit his custom circuitry inside. By hacking off part of the CYWM6935 module and cutting some protoboard in the same shape as the original PCB he managed to get everything into this tiny portable package. Now he’s looking for a way to incorporate a charger, and an on/off switch.
If you don’t have an old cell phone sitting around you can try building a spectrum analyzer that uses a character display. But we’d suggest hitting up your friends for their old cellphones. The screens are used in all kinds of fun projects.
Just when you think you’ve heard all you can about the N900 PUSH competition, we have some more news for you.
The original PUSH competition was only for UK members, but now Nokia has introduced the ‘Mod in the USA‘ N900 PUSH competition. Similar to the original, anyone (within region) can submit a cool mod, hack, useful creation that would use the N900. Winners will be selected, and thats when the differences start.
There will be a $10,000 for 1st prize, and smaller prizes for 2nd and 3rd. Plus a trip to Vegas to showcase the 3 winning hacks at CTIA 2010 as well as funding, N900s and support to build the mods.
Don’t have an idea but still want to try? They have a discussion group to get the juices flowing, or you could always discuss in our comments.
[Update: The original PUSH competition was actually world wide. Thanks Matt and Ricardo]
Not too long ago we asked our readers what they would like to hear about from the PUSH N900 winners and their hacks. We got some silly questions, and some serious, we asked both and now the PUSH teams have answered.
The day has passed, the party is gone, and all that’s left is the final interview. The Light Hack Crew gave us a somewhat shorter response then what we were used to, but it turned out to be just as sweet.
Like all great things, they must come to an end. As such, at 10am PST, this morning – our N900 Push competition came to a close. We had some really awesome answers, some really round about, and of course the obligatory – really bad ones. For those that are just on the EDGE of your seat waiting for the final concluding answer to stop the arguing and fighting – to settle this whole dispute. The answer, and the winners are…After the break.

Solderin Skaters are really making progress. They’ve gotten their printed circuit boards and mounting equipment all set to go, and the code and algorithms are really shaping up. All that and more updates are seen in their latest video, and blog entry.
