I bought 30 BrickPi+ kits, and so far 5 of them do not work. For all the brains, I connect the brain to ethernet via my laptop’s ethernet port. Then, I power the brain by connecting it to my laptop’s USB port. I open Google Chrome and type dex.local into the URL bar. The following happens for these brains:
— Brain #9) It will not load the VNC page/ dex.local. Only if we connect the brain to a TV with HDMI can we open Scratch and code.
— Brain # 12) It will not load the VNC page/ dex.local. I have not tried connecting it to a TV to see if it works through HDMI.
— Brain #13) The ethernet port lights do not light up, so it will not load dex.local or send and receive any data.
— Brain # 25) It will load dex.local and log me into the main page, but Scratch does not open. The Scratch’s command window will immediately close as soon as I click on the Scratch icon. I tried opening Scratch through the various other icons and programs in the desktop folder, but nothing has worked.
— Brain # 27) After about 10 minutes of refreshing, I could load dex.local with this brain, but as soon as I clicked on the VNC page, the brain would disconnect. This happened several times. Finally, it loaded the password page but disconnected again. After more refreshing, the brain finally loaded the password page and then the desktop.
