• Screen inversion

  Rich Maynard • 01/27/2020 at 15:57 • 0 comments

  Turns out that the Pi display has a better viewing angle from one direction than the other. The Pi Foundation flipped the display to account for this, assuming that the user would be looking down on the display from above.

  In my case I think the user will be looking from 'below', so turning the display over makes sense. Which means I don't have to lengthen the jumper wires, but I do need to make some modifications to the mounting hole positions and screen cutout.

• Improvements

  There are a few changes that need making to the arrangement of parts:

  • Jumper wires need to be longer to provide power to the Pi from the screen
  • Jumper wires need to be longer so touchscreen can work over SPI
  • Battery needs to move to right so power supply cable actually fits in around screen (component box could then be a bit bigger)
  • Component box doesn't line up properly with its lid
  • Would be nice if it were a little easier to remove component box
  • Paint it, or maybe use some veneered MDF instead

• First draft of the assembled PiBox

  Opening the case to find a removable Bluetooth keyboard

  Removing the keyboard gives access to the 7" touchscreen

  Removable lids cover the Pi, breadboard and a little compartment to store components

  USB hub to allow better access to Pi USB ports

  Cutout allows access to the button on the battery to display charge level (red LEDs)

  Component box is removable to allow access to Pi HDMI and power ports

• Starting to work put where everything goes

  First view of the bits to include

• Power source

  I chose this power source as it can provide 5v via the USB connector, but also has onboard solder pads to provide 5v, 9v and 12v which might be useful for projects

  I used a couple of 18650s reclaimed from an old laptop battery pack
  

• Introduction

  Rich Maynard • 01/24/2020 at 10:49 • 0 comments

  I had an unused drill bit case and a Raspberry Pi, so put them together with some other components to make a laptop aimed at makers.

  I looked around for a supplier of the drill bit case without the drills, but can't find one. You can get the case and 99 drill for less than a tenner on eBay anyway.
