The last few weeks have been very busy, with all the conferences, sickness, day job, etc. so I fell a little behind with my plan to have regular experiments published here. Hopefully that will improve.

In the mean time, I ran out of boards for Tote (there are some people wanting to build it, after all), so I ordered another batch from Dirty PCBs. It's still version 4 of the boards, but there are some small improvements:

• the PCB is thinner, so it's lighter and leaves more room between the servo horns and the screws,
• there are more holes in it, which makes it even lighter, and hopefully makes it easier to attach stuff,
• the mounting holes are not metalized anymore, so harder to make a short circuit,
• the holes for the servo horns are slightly bigger, so the horns fit easier.
