With disassembly nearly complete, we tear into the control wheel. It's a dead ringer for the one we found in the original Echo, complete with its geared encoder wheel.
That's just fine by us, since it means at least some replacements parts can likely be shared between the original Echo and the Dot.
It also means servicing instructions for one will likely be echoed by the other. All in all, it's a win for fans of repair and bad puns everywhere.
