Sony cameras - dusts leak to sensor

Dusts can creep into the E-mount interface and they are then be sucked to the sensor:

And these dusts are micro, cannot be blown off with a blower. You must use alcohol to clean them up.

I found this O ring from a local hardware store for about $1:

It is about 45mm x 2mm, perfect to seal the E-mount slot:

Works for a6000, a5100, a5000 and all E-mount cameras including A7 series. No problem for lens swap. May keep water out too, to some extent.

If you cannot find such an O ring, you may use a proper rub band, but might not be so friendly to lens swapping:

Don't fix it if it is not broken

As a tweaker (other than a trouble maker), I know that rule, very well; so I never update any software. Somehow I installed a new version of the TouchMousePointer on my Miix, thought I had a copy of the old version to go back. Well, as always, the new version is erratic and double-tap no longer work (unless I do it extremely quickly). To make it a though tragedy, I can no longer find the old copy in my storage!

After lots of searching, the oldest version I could find is and, fortunately, it works fine on my Miix. To save your trouble finding it, here I uploaded it to my server:

There are even older versions around, 1.0.32 and 1.0.33. They work more solid than the, but they lack of an essential feature: click through the touchpad. For example, if there is an image file underneath the translucent mouse pad, you can still double tap on the mousepad to open it, as showing below. With this fantastic feature, the mousepad takes virtually no space/room on your touchscreen, as you can still see and access whatever underneath, and you can move the mousepad to anywhere you like without blocking anything on your screen.
