The developer of personal dosimeters presented me with an interesting gift at one of Skolovo conferences in early 2011. It was a funny DO-RA gadget made in the form of an Easter egg and packed in a large cardboard box like a smartphone. Apparently, its designers new that their boss Viktor Vekselberg, chairman of the Skolkovo Foundation, was fond of Faberge eggs. They made a plastic copy of the famous Easter gift of the Russian Imperial Court.
I found a dusty box with the DO-RA gadget just before a business trip to the United Arab Emirates. The device had no battery and was connected to Apple smartphones via a standard audio jack. It is worth noting that, starting with the 7th iPhone model, the Apple Inc. no longer releases smartphones with an audio jack considering it an anachronism. However, the abandonment of the quite utilitarian interface such as audio jack coincided with the release of expensive Airpod earphones. Well, it's their business to earn money on all sorts of restrictions.
