Here is my first project in wearable electronics.
A Lilypad-Enabled cap with leds and buzzer.

Enjoy!

I built a Pulsecounter & Datalogger using the new Arduino Ethernet and Arduino22 environment.
It includes SD card logging, webserving, NTP clock synchronization over the ethernet.

You can find a description along with the code (GPLed) at http://marco.guardigli.it/2011/11/tomware-arduino-ethernet-datalogger.html

I will have to evolve it including FFT capability of high frequency multi channel analog samples. Will keep it posted.

Enjoy,

I successfully implemented davekw7x's suggestions (THANK YOU!), with arduino 2009 boards and wiznet 5100 shields.

Here http://marco.guardigli.it/2010/11/arduino-wiznet-ethernet-shield-proper.html are some details and pictures.

After the mod, everything works fine.
