Lego PF Remote NXT Sensor

This is my version of the PF Remote sensor made by Dave of NXTPrograms.com

I made this version with a differential input giving one four speed directional output to which I attached a rotation sensor, the rest is programming.

I do not have the RCX style rotation sensors so I used my own optical sensor
It is a simple coloured drum and a light sensor, theres some clever tricks to determine direction but because the sensor relies on full rotations it is a little slow to respond hence the 1 second update (& heartbeat tone)

this is just a test to get the NXT to 'see' the IR remote, it is basically a home made PF receiver Sensor but as it relies on having the IR Receiver battery box and two motors and another NXT sensor it is not practical, The best remote for the NXT is still another NXT! (via BlueTooth)

I got the remote from the Technic bulldozer, I believe Lego sell it on its own on their shop@home website.

Nicely done, i was reading the article from Dave Clark on the NXT step and saw your links, thanks for sharing. Yes a NXT for dummy remote is needed as much as it was useful on the RCX when working on prototype and testing ideas.
