Project notes

I2C distance is normally a few meters (2 a 3), 400pF wire. WII-remote goes beyond this or use a driver P82B96DR (at Farnell for €4,-) to reach 50meters, 3000pF wire. For this extensions you need 15V bus-voltage.

Going cheap wireless is possible with this lc module:

Atmega328P has opration voltage from 1.8-5.5V. Possibility to use 5V over the bus, I guess..

Personal introduction

Currently I'm working on my internship at the Control Systems department of Electrical Engineering at the Technical University Eindhoven. As a master student I'm interested in Control engineering, Robotics and Electronics. For several years I've been working at the innovation laboratoria of Fontys Eindhoven, where I designed embedded electronics. Also I gave lectures in mathematics and embedded programming.

Lateron you will see my blog been updated with more information.... See ya!
