My first recourse would be to contact LEGO for a replacement part.

Hy to all !

I've a Ris 1.5 since 2000 and everything was going good. Until today.
I was assembling a lego pneumatic switch with a touch sensor to detect the
center position on the switch, but the sensor seems to have lost
sensibility. When i touch it the maximun value i get is more or less 78 (as
reading on the RCX with sensor_type_touch and sensor_mode_percent using
NQC).
With this low value it can't switch to "1" loosing it's functionality.

So, I opened it and i found that it works with a small piece of rubber which
once pressed against 2 small metallic plates it makes the contact. But
somewhere this rubber lost part of it's conductivity.

The question is, what can i do (before buying a new sensor) ?

Thanks to everyone.

This is good advice. I've had a motor and a couple of 8448 "hydraulics" that have failed and LEGO has cheerfully replaced them. --Russ -----Original Message----- From: Mark H. Near [mailto:markn@SCOCA-K12.ORG] Sent: Sunday, October 05, 2003 4:37 PM (...) (21 years ago, 6-Oct-03, to lugnet.robotics)
