Another way of using the Power Functions remote handset to control the NXT

Philo, author of many a NXT LDraw part and renowned expert of NXT electronics, has published an artcle on his web site on another possibility of using the Power Functions remote handset to control a NXT. In contrast to other already existing solutions to do this (e.g. Dave Parker's or Mike Brandl's), Philo's one allows for using all nine different combinations of the PF handset:

"The idea is simple: combine the outputs of the PF receiver with well chosen resistor values to obtain a different voltage for each combination of controls and measure this voltage with the NXT."

Yet, you need to do some soldering inside of the PF receiver for that.
