PARTS

- 4x spring loaded micro sd pcb components
- Keyring attachment
- Duct tape

TOOLS

- Coarse sandpaper
- Super glue
- Soldering iron
- Clippers

HOW-TO GUIDE

Step 1. First we need to make sure the micro sd sockets are smooth and flat. Clip and sand off any protruding parts.

Step 2. Disassemble the micro sd sockets. Remove the metal shielding, then take out the spring mechanism.

Step 3. We need to increase the friction so that the memory cards stay firmly in place when inserted. Take four small strips of duct tape and layer them on top of each other.

Step 4. Glue the shielding back onto the plastic section. Repeat this for all four.

Step 5. Add the keyring attachment to one of the corners.

Step 6. Glue all four of the sockets together so they are back to back and top to tail.

Step 7. For extra toughness, weld the shielding together with the soldering iron.

Step 8. Clean up the solder joints with the sand paper and you're finished. You now have a tiny microSD card holder that can hold up to 4 cards. Couple it with a tiny USB reader and you have a tonne of storage available in your pocket.
