    I have been clearing out my loft, and in a suitcase found some old electronics.

    Most are circuit boards and wires, but I did wonder if the following 3 items are of any use.

    I will be perfectly honest and say I have no clue as to what they are, or what they are for.

    I just wondered if they had any value on the secondary market, or I should just pop them into the recycling bin lol?

    The items seem to be:
    a gemini 831 dc/dc converter
    a coaxial relay (2 photos)
    and a weird grey metal box that seems home made.

    I am in the UK.

    I have a basement full of similar 'valuable' items.
    Unless you are into DIY electronics and keep them 'just in case' and you can use them for parts, you will be hard pressed to find a buyer!
    Even the IC's are probably passe now.

    Looks like thingy dingy 2 might hold the greatest hope for its component stripping for anyone that is still using discrete components.
    With that DC DC converter label looking as if it might have fed many meals to a silverfish insect.
    The 3 others might only interest an RF experimenter or a ham radio enthusiast with RF switching needs.
