 | | RCX has a fast clock, was Re: Rolling ball clock revisited
|
| 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)
