I am mystified by all the reports of failed SD cards and wonder where these are coming from because I have many RPis as old as the first originals up to the 3b+ without failure, two Pi run 24/7 for ye

The WittyPI III from UUGEAR will take input to 15V to power the Pi, the WittyPi also contains an accurate RTC and lots of automatic power up and power down programming options. I use 4 of these to con

You DO want high resolution and might have to juggle the display parameters in boot. I found the 10" Winmaxit flat LCD HDMI on ebay is pretty dang good, plug n go, its bright, adjustable, This is my s
