Hello dave, (...) A made an experiment this night using a RCX 2.0, the clock was fast by about 10s per hour. I suppose that this problem comes from bad capacitor loading of the crystal used on RCX. Crystals need to see some capacitance to oscillate (...) (20 years ago, 8-Dec-04, to lugnet.technic, lugnet.robotics)

Hi Rob, (...) I tried a similar mechanism (a large inclined plane with a width reduction in the end), the problem is that LEGO balls are somewhat rough, and they tend to form a locked arch above width shrinking. I even tried to add a stirring (...) (20 years ago, 8-Dec-04, to lugnet.technic, lugnet.robotics)

(...) So, what exactly is a gravity tube? Maybe you mean something like: Empty Full Half-full | | |o| | | | | |o| | | | | |o| |o| | |___ |o|___ |o|___ |_____ |o____ |o____ Hence, when a ball comes in (from bottom right of the tube), it pushes a ball (...)

It was interesting to read this bit off your website-- " The problem should have been very simple: each minute, start the elevator until a ball is detected by one sensor.
