DiveDuino – DIY dive computer
“ What is DiveDuino?
Right now Diveduino will not replace your dive computer, but it can log your depth and temperature during your dive, saving it to a MicroSd Card in a TEXT file format so you can import it to excel and do your fancy dive profile graphics, no need of special $100 USD cables that all the diving equipment manufacturing companies sell. Plus it has a display for that information with a actual graph of your dive profile.How it came to my mind?
DiveDuino came to my mind since I am an active diver and I enjoy the sport. I am an electrical engineer and at work I came across with the Arduino platform. Dive computers are expensive, if you want all the fancy features, you can find some computers for about $150 USD and others for about $1500 USD. Every basic dive computer has this indicators: No Decompression Limit(NDL), depth, temperature and elapsed time. So why not create something with the help of the Arduino open source platform, I found a sensor that could interact with Arduino and the rest is the prototype that I am building.“

Make a slim watch with ARM Cortex-M3 EFM32
„Hack-a-Gecko project by Anders and Adam
How to make a very slim watch and keep battery life long? In this Hack-a-Gecko project, they tried to catch two birds with one stone.
The Idea
We thought it would be cool to utilize the extremely low power EFM32 in combination with an extremely low power display to create a wrist watch demo application. And usually, the smaller and thinner something is, the cooler it is. (Admittedly, wrist watches do not necessarily follow this trend… big watches.)
Anyway, we wanted it slim. The starting point was the memory LCD display from Sharp (link). It is truly a Nano ampere display technology. And it is also thin, only 0.75 mm. A watch also needs a battery, cool new technologies exist such as the Thinergy battery, but the voltage of 4.1 V is a bit awkward. We decided to use a standard 3.0V CR1616 cell as it can power the EFM32 and display directly. Thickness of battery + display is 2.35 mm, is it possible to design the electronics as well within this thickness limit…? Challenge accepted!“

Raspberry Pi: MPEG-2- und VC-1-License in shop
Now you can use the Raspberry as a Mediaplayer and further software updates will allow encoding to.
Pocket Mini Computer
“ The Pocket Mini Computer was designed by Jeff Ledger.
The Pocket Mini Computer is pre-installed with a COLOR BASIC. COLOR BASIC is similar to the BASIC found on common microcomputers of the 80’s and early 90’s.
Explore micro computing with a machine which:
Can be successfully assembled in an evening.
Can be programmed in BASIC. (and other languages)
Can play games and run programs.
Most importantly: Can be understood.
The Pocket Mini Computer Kit arrives as a project which requires a small amount of soldering, all components are „thru-hole“ making it an easy project for anyone with modest soldering skills.
The Pocket Mini Computer hardware supports:
VGA Output
Right/Left Audio Output
PS2 Keyboard
Wii Classic/Nunchuck controller connection
Optional SRAM (32k extended RAM using 23K256)
Optional IR receiver connection
Optional I/O experimenters‘ port“

What is ANT+ and what can you do with it and a MSP430 + Android ?
ANT+ Between MSP430 and Android
„Smartphones are equipped with dizzying array of wireless communication capabilities. Some of these features just go totally unnoticed. One such wireless communication protocol is called ANT+. A friend of mine wanted to make a working prototype of an idea he had using ANT+ technology. While there are other mcu’s (read atmega/arduino) already had some libraries and code written for communicating against ANT+, it wasn’t enough for me.
- Most of the existing code only worked as a slave, where it just tried to receive data sent by Garmin Heart Strap.
- This slave implementation was only on either arduino or PC (python and C)
What I was more interested in was to leverage the ANT+ radio to not just receive data, but also send data. I wanted the mcu to interact with the world and use ANT+ to transmit data to my cellphone, for example.“

iPhone RFID with ID-12
That’s cool, on http://blog.section9.co.uk/2010/03/iphone-rfid-reader.html you can see the work process in pictures. The RFID chip is from http://www.id-innovations.com/new%20launch.htm.
„The idea behind this project is to see what the iPhone’s serial is capable of and to try and have a little fun with RFID along the way. This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well.“
