Notes on the LittleArm Waldo

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.

1. You must install the arduino software to operate the Waldo.  Download it here.
2. The Waldo may require calibration to align with the motion of your arm. To do this just remove the pieces from the spindles and align with the position of your LittleArm and reattach them.
3. The Waldo is susceptible to electromagnetic interference (florescent, lights, other electronics). Though it is shielded, if it seems to jitter, this might be the cause. Take it to an  area away from potential interference and try again.
4. If the Waldo and arm go out of sync, simply reset or restart the LittleArm.
5. The Waldo utilizes 10k potentiamters as the sensors, should you wish to replicate or modify it. Here is a wiring diagram.​

Those are the main things that might come up. Hope this helps. Enjoy your Waldo.
