Right now I'm building the first pneumatic muscle. I had to find additional connectors for the solenoid valve unfortunately, but that was only a minor setback. In case you haven't noticed, I'm basically uploading a lot of project logs at once, because I procrastinate. A LOT. I have a video of the first pneumatic muscle working, and just so you know, the socket wrench in one end is NOT how the finished muscle will look. I'm posting this on what will hopefully become my project channel.
