The aim of this project was to build an MP3/WAV player using just a FPGA, some RAM & a stereo DAC. The project consists of a custom 32-bit soft core processor running at just under 60MHz which decodes the MP3 algorithm in software with no hardware acceleration apart from a single cycle Xilinx multiplier unit.

Just a few rules:
- Add a comment on the thread http://community.openpicus.com/forum/projects-place/1194/contest-get-free-flyport-ethernet-easter describing the application you aim to create using Flyport Ethernet and Lighting nest.
- The winner agrees to share with the entire project with the Community (source code, description, maybe a video or pictures)
- The contest starts on 27th March 2012 and it ends on 5th of April 2012
- openPICUS Team reserves the freedom to choose the application that it considers most interesting
Good Luck!
Flyport Ethernet is a miniature web server module featuring a fully integrated 10/100 Base-T ethernet interface and several interfaces to the ‘real world’. Flyport Ethernet integrates a 16 bit processor which runs custom applications and an Ethernet interface controller with integrated MAC & PHY, hardware cryptographic security and a unique MAC address. An RJ45 connector can be mounted on the module, or routed at external addons boards.
Flyport is powered by openPicus, an open source framework and serial booloader. The free openPicus IDE allows to create applications, to import web pages and to compile and download code to the module.

The SMD Codebook is a comprehensive internet database of the two and three letter codes used to mark small surface mount parts. This is an indispensable resource for repairing and reverse engineering SMD circuits. [via]
SMD devices are, by their very nature, too small to carry conventional semiconductor type numbers. Instead, a somewhat arbitrary coding system has grown up, where the device package carries a simple two- or three-character ID code. Identifying the manufacturers’ type number of an SMD device from the package code can be a difficult task, involving combing through many different databooks. This HTML book is designed to provide an easy means of device identification. It lists over 3,500 device codes in alphabetical order, together with type numbers, device characteristics or equivalents and pinout information. Sometimes I’m asked to put IC information in the codebook. There is some information about ICs – but first and foremost the codebook is intended for discrete devices. Some ICs have been included, usually these are 3/4 pin devices or RF circuits I’m interested in.

3D models in Google SketchUp look great, but with a few extra plugins the results can look photo-realistic. In this tutorial we’ll cover our experience with the Maxwell for Google Sketchup rendering plugin.
The Maxwell Fire engine is easy to use. It’s integrated directly into SketchUp so you don’t need to open any other application to render photo-realistic images of your models.
The goal of this guide is to help you make awesome looking images of your projects for documentation and presentation.

Resin-based 3D Printer kit… [via]
I have been dreaming about having a 3D Printer at home for many years, but the ones with good quality are not affordable and the low costs just deliver poor quality. Sounds crazy but I decided to build a high resolution 3D Printer by myself at home (people actually said that I was crazy and this was impossible). The funny thing I never saw this type of machines in real life, and still haven’t seen one besides the one I built.
Now that I succeed building the first prototype, the target is to bring this low cost 3D Printer to every home, so we are developing the first affordable one with high resolution. I hope you enjoy our blog, follow us and you can have this printer in your home soon.
