We recently shipped the LittleArm Waldos out to many of our kickstarter backers. Since it is out there, we thought that it would behoove us to do a quick post about potential stumbling blocks to users of the waldo. Since most who ordered the waldo are skilled hobbyists, we will quickly detail tweaks and solutions to the Waldo should you need to troubleshoot it.
Those are the main things that might come up. Hope this helps. Enjoy your Waldo.
