Part of my plan to make a low-power wifi-enabled magnetometer for AuroraWatch UK. This shield is designed for Calunium, but will work with full functionality on the Arduino Mega2560. It will also operate on a standard Arduino but flow control and some of the GPIO features of the RN-XV are not available.
The shield uses logic level translators on both the inputs and the output from the SD card. This means it can be safely used in situations where there are 5V devices on the SPI bus (eg MicroMag3), see blog.stevemarple.co.uk/2011/10/interfacing-33v-devices-to... for a discussion of the problem.
Eagle design files are available under CC BY-SA 3.0 licence at github.com/stevemarple/RNXV_SD_shield.
This is something I had been meaning to complete for quite a while. I needed something that was portable, clean and easy to store random things in to prototype stuff on the fly.
The Proto Desk allows me to sit on the couch with my laptop and arduino and mess around.
$9 ARDUINO lesson 2. I copied the code from the web site but had to add the int definitions. push the button and light the LED!

Bearing, Distance and ETA to a Way-point
The bearing can be shown either as cardinal directions or in degrees, and can be shown as relative or absolute in respect to true north.
The ETA can be based on either the current or the average speed of travel.

Built after this schematic: www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1206874649/8 - I only added two capacitors to buffer off voltage spikes when inserting the card as described here: elm-chan.org/docs/mmc/mmc_e.html

My Arduino Synthesizer. Inspired by an article on Make (hooray for make!). It has an interface built in Processing to control the frequency and waveform.
check out my blog post for more information, the source code, and some videos.
