Minimal RaspberryPI Base

Introduction: Minimal RaspberryPI Base

This is a plan for immobilising a Raspberry PI in a domestic environment, without children or pets, in order to run it without killing it with static.  I have no idea whether this level of precaution is required, but it's been about two weeks, and it hasn't died so far.

Step 1: Parts

I used a block of 4x2 construction timber, left over from a painting job, some 25mm x 8g screws, left over from a gate numbering job, some anti-static bags cadged from a computer shop, and a Raspberry PI B.  

Anti-static bags come in three sizes, in order from small to large: memory, disk and motherboard; I ended up using one of each.

Step 2:

Turn a disk-sized bag inside out, so that the writing that would identify the disk isn't exposed on the surface.

Step 3:

Make a fence of screws, through the anti-static bag, into the timber, around the Raspberry PI, with at least one on each edge, avoiding the places where you need to plug things in.

(Slightly unrelated, when you're plugging in the SD card, turn the board over, to check that it's all the way in, because the insertion force is quite high.)

Step 4:

If you need to transport the PI, you could protect it with a strip of memory-sized anti-static bag and hold it in place with a rubber band, then wrap it in a motherboard-sized anti-static bag.  I have tested this a lot less than I've tested the rest of this plan.

    Some notes from experience:

    - so far, my anti-static bag hasn't killed my PI; YMMV

    - I was bending up the memory cards, getting them in and out, so I had to move the PI on the block of wood, so that the memory cards overhung the edge
    -- getting it close enough to the edge, without breaking the block with the screw is a challenge at which I wasn't entirely successful
    -- next time, I may put the edge screw in first, and then arrange everything else around it

    - an EDI (hard-disk) cable will fit over the block of pins, with some extra holes left over on the EDI cable; to make this work, any screw near the block of pins has to be very far down on the board.

    be sure to check that your bag isn't conductive :0 (its the main part of why they can be anti static) anti static doesn't mean non-conductive ;)
