Re: Battery-powered calendar-type display board

The pi can get the time from the internet so no clock chip needed.
The pi can talk to the laptop via WiFi, so you can copy files to the pi.
The display could be a small HDMI screen, so can show dates, times etc.
The tricky part is having it all battery powered.

Yes they claim it fits any pi, so if it does bend any pins you could get your money back.

Re: How to control second computer with rasberry pi

Maybe use the WiFi/lan to receive on the Windows pc commands from the pi. E.g. using python/mqtt. The pi can read the encoders and send data to the pc.

Re: GPIO Pins controlling software

Yes once you have the script responding to switch/button presses, instead of turning on an LED etc., you can run a script (or executable) that starts your desired program, or execute a system call to do things etc.
Or have a look at xdotool for keyboard/ mouse simulation to control other programs.

Re: USB device (1090MHz) disconnecting - with error -71

Might it have been an overheating issue ? My NESDR smart v4 dongle (aluminium enclosure) runs too hot to touch. It is plugged into a pi2 USB port - I might add a short USB extension cable.
