In Turkish the word gadget is "köj" but it is no longer used at all. The last time I heard someone use it was by a very old nomad Türk (they are called yörük) to name those locks with a key shaped like a horse shoe. I asked what köc meant and he pointed at my eyebrows (which is Kaş in Turkish and sounds very similar to Köj and said "Köj means something which is useless alone but extremely useful when it's with something. Your eyebrows are useless alone but give character to your looks and express your emotions more than your words and actions.". Then I realised that eyebrows were human gadgets. 
Today the word is used for the little part you use on a bow or gun to aim:

This is called GEZ.
We also have it as a reiterative in the form of "araç gereç" meaning "tools and gadgets"
