    have a look the photo,

    the pins are bent not much on some but pretty badly on others.
    Its still possible to put them on PCB with screwdriver but cant sell as regular item.

    They are old too, I tried to wash them but the black color is thin + comes off.

    Would sell some of these or the whole lot for a deep discount (the whole lot would cost about $6 to ship).

    2

    A lot of switches and pushbuttons, some with LEDs

    3

    A lot of sockets, some 3.5mm some smaller standard as well a few DC jack sockets
    The small kinds are gold plated look good, I have no idea what they are good for.

    4

    Vintage blue clear LEDs probably very early kinds (also as item 25pcs on sale).
    These are really old LEDs tone seems to be a bit different.


    Less than 100gr = $3.98 shipping

    So, are we to assume the free and we just pay shipping? ...or is there some standard price for obsolete displays that I am unaware of?

    the leds are for sale but you can have a free one

    they might be considerably old

    this is when cmos was designed 1970s to early 80s

    i have 80s resistors

    gone from the market for decades but you still use these old ics

    didnt sell yet and its not suitable for ebay I think.

    Price point is 30 cents or so + can drop in the damaged displays on the left side.

    Now, today I got more ewaste / NOS, its always a surprise, I got some TDK piezo buzzers in small white case with spring contacts internally, recycled small speakers, and guess:

    Much more LED displays. These kinds are a little better, most are 2-digit, some LED bargraphs too. Different sizes too.

    Price point is similar, 30 cents, wouldnt reject more for the good ones but some are also cheap new.

    I got other NOS LED displays from Germany too.

    And (but thats not a flea market items), two sheets LED bargraph displays in green and blue, with 5 bars each.
    These are pretty uncommon and hard to find. I put them on ebay soon.

    What I list here is a small percentage of parts I'm handling.

    Most smaller parts now find their way into Joule Thief kits, I try to sell a parts kit with good value, and useful for more than
    just a joule thief.

    By the way VINTAGE ELECTRIC PARTS are on sale since today,
    listed as 380 grams item (selling by weight).

    Some of the chinese resistors are particulary nice and these kinds are still made and sell as single pieces.
    Not all the parts are chinese, some are from Europe. I collected / ordered these for 1/2 year or so.

    What else is new today.... lets have a look

    TDK 33uH 2.1A inductor can sell 10 or 12 cents
    A 116pcs transistor kit incl TL431 and XL1225 Thyristors
    1 Mega Ohm potentiometers can sell 20 to 25 cents, took me a while to find these
