Changes

The logging rate can be increased (Turtle Blocks104) by patching one of the Turtle Art files, <i>talogo.py</i> in directory <i>home/olpc/Activities/TurtleArt.activity/TurtleArt</i> changing <i>self.max_samples</i> from 1500 to 150, This reduces the repeat loop from 15mS to 4mS but there is around 50mS jitter. Datalogging can be done without patching the file, using wide switches and shallow ramps keeping the events within the capability of the XO laptop.
