Re: Questions about A rack for a Raspberry Pi Cluster

I got a unit from Amazon that can hold 5 pi 3's, actually with multiple kits you could add more. It has no side peices so ventelation is better. I will be adding a fan system this summer as they still generate heat. https://www.amazon.com/gp/product/B01D9130QC/ref=oh_aui_detailpage_o06_s00?ie=UTF8&p...

The sense hat is way different then the others and which I do understand why. My solution, probably not the ...

Re: Whats a good bash/terminal tutorial?

Hi, there are also some decent tutorials at www.adafruit.com

They are listed in the Learn section then Raspberrypi. Different ones to command line and some simple automation of daily tasks, I highly recommend them.

Re: VNC no longer working properly...please help!

Not sure about this but I think you have to boot into GUI for VNC to work. Also make sure you have the right user name and password in the viewer software. Got caught on this myself.

This could all be wrong and I am sure someone will correct me!

Re: Can'r Enable VNC

I had no issues with running the Pixel version of Real vnc. Make sure you set up your network ssid and pass phrase. After that from command line type sudo vncserver :1

Works fine on Pixel and tightvnc on Jessie for me.

Re: Raspberry pi 3 booting issue

Probably a corrupted SD card or bad power supply ( not enough current). I just set up a brand new Raspi 3 today that had an unsoldered SD socket. Might want to take a close look at yours but I think my situation here is very rare.
