Thanks so much for taking us all along on your adventure.

Oh yeah, I've had my share of that even on not-so epic rowing events! Part of is you said is that on a boat you are using your hands to manipulate and feather the oars, and there is a lot of relative motion as you grip and twist that causes calluses and blisters. I'm hopeful that on the rowing bike it will be possible to have a grip and hand position that is easier on the skin since it's just a straight pulling motion all the time. I'm sure some of the regular rowbike rowers/riders can chime in? I know there is at least 2 or 3 on this message board!

Justin, you really made impressive work in such a short time.
When I saw the beginning of this post and the short time to departure, I thought: no chance.
but you have done a mass of work.

Are there any addition tweaks to the current 3.1 firmware coming out in the near future or can I proceed with the existing version of the 3.1 firmware on my eRowbike project?
Warren said:On your cord drive; I used 1/8" braided kevlar, but you may have similar issues. Over time; water, oil and grit worked into the cord at the pulleys. They looked fine but eventually ground through the internal fibers and pulled apart. Take lots of spare line. It is much lighter than chain, and might come in handy for other stuff too.

justin_le said:Did the grit and oil also ended up causing wear of the pulley grooves as well? I machined these current pulleys from a piece of round PVC plastic stock I had lying around, but it sounds like I may want to remake them from a material that's tougher against abrasion.
Warren said:Nope. Never had any problem with pulley wear. The turn around pulley, at the end of the boom, was the aluminum one from Thys. The block pulley was nylon, from McMaster-Carr, with a sealed ball bearing replacing the original bushing.
justin_le said:OK great to know. We ordered some of these Macmaster Carr pulleys but they didn't show up before the weekend so we'll see if I have time to make them into spares.
