We do not have any projectors up yet. That is one thing we are looking into for future. We would like to use a cart with a desktop setup and the projector that can be moved class to class when needed as these classrooms are not secure.
I installed the computer room in January 2019 with 14 desktops, 1 RACHEL server and 1 file server. It ran till the end of school in May. The class has been in sporadic use this fall due to the unrest that has caused the schools to stay closed. However, we use the classroom for our kids club sometimes on Saturdays and 1 off days when possible until school resumes. So far we have not had any issues reported or that I saw when I was there in August.
I have about 12 spare microsd’s already flashed and waiting and 1 to 2 USB duplicator to re-flash any corrupted card in about 8 minutes. The class was re-worked this August to add an additional 6 desktops.
