This was just discussed on lugnet.robotics.rcx.
I have an rcx 2.0, and you can see what I did here:

I used a 7809 voltage regulator.
Note that this requires some basic electronics and soldering skills.
I would not use a wall wart, because the voltage is not very well regulated.
Btw, you cant hurt your rcx by using a 9v 1a power supply. You cant hurt
it by using a 9v 15a power supply. The amp rating is a maximum, the rcx
will only use what it needs.

| I'm sorry, I can't really make out that photo. Do I just connect the 7809 ic between the power supply and the rcx? Do I connect to the + or - or use 2 and connect to both? thanks -----Original Message----- From: news-gateway@lugnet.com (...) (23 years ago, 12-Feb-02, to lugnet.robotics)
