June, is a beautiful period in Stockholm. Many students have left their schools for travel or and fun, or for intership and work. However, our Isaac team, are still continuing to work on this project. The Critical Design Review (CDR) is coming up, we have a lot of work to do. Although we have submitted the SED v2.0, we still need to do some modification and iteration on the mechanical and electrical design. We need to prepare the powerpoints for the CDR presentation. CDR requires most of key design, which covers a lot of technical knowledge and problems. So we have to prepare for the questions and comments from experts on these techniques. OK, let’s go on.
