We are faced with the fact that the Raspberry Pi 2 can be spontaneously ejected micro SD memory card. It happens suddenly and at the most inopportune moments. An internet search showed that we are not alone. The problem arises in many, and it is connected with the choice of a supplier of micro SD card slot. It is clear that you need to save on everything, if the computer costs $ 35.

But what can we do? It seems that the release is associated with weakness of the latch that holds the card, too powerful a spring and thermal extensions, when our device works, that leads to the release of the map at any time. This is no good. The weakest link was the only movable mechanical unit.

First, we wanted to change our Raspberry Pi on the other, and the supplier said "sure, we will change". But then we thought there is no guarantee that after replacement we will not get the same instance with a defective slot. And it again will throw the card. Maybe not right away, but the risk will remain, especially since the host will wear out. After some reflection and analysis of the design of slot, we found a beautiful solution.

Important: do everything very carefully and in a sober state. If your work fail - we are not liable. But we did it.

The blade of a knife (in our case the scalpel a Swiss army knife) raise the flat spring, which is part of the housing and preload mechanism on top. It is enough to bend up to 15-20 degrees.

Through the resulting gap carefully, but firmly push on the spring by the paperclip (we used a special tool), pushing it into the space reserved for the memory card. As a result, the mechanism falls apart into two parts, and take off the latch and spring.

The latch is easily tapped out from the slot.

The spring had to be removed by hooking her with the same knife.

The knife blade is lowered back to a flat spring, so that nothing was sticking.

Insert the card, and now we have no mechanical parts, only the electric contacts. Yes, the card will have to take out is not pushing on the end, and hooking it with a fingernail, but does it matter? Because the reliability of the system has increased.
