I just spent the last four days building the control box and I want to say that the build manual has been a joy to use. There is a lot of work to do but it is ordered in such a clear and rational manner that the process just flows along. If you are reading about the AR3 wondering if it is a good project to start, I can say it is a fantastic learning opportunity.
Thank you Chris for your meticulous efforts. I am having a great time!
