Springloaded and very, very sharp tips...

Not a clue as to what they're really used for, but I figure that with an even one hundred of them, I'll find something they can be used for.

If I built a mini hexapod robot with these as the tip of the legs, though, it would probably be capable of climbing vertical walls...
(Would need a bunch of very small micro servos or other motors, though. Need to check eBay again... )

    They are used for testing PCBs. Look up "bed of nails" testing.

    Ah...

    Should have guessed.

    Edit:
    and now I found 1.5Gram linear servos...

    Those are just so cool that I got to get me some... Or more than some...
    3.7gram rotary servos are cheaper and not all that much bigger, but... DANG! 1.5 GRAMS!

    Thanks for posting this. It reminded me that I need to get some pogo pins for an upcoming project.

    It looks like they are actually 4 grams total. That is still pretty light. Let us know how they work out.
    I found this on EBay last night. I did some checking and seen what they are worth so I bought it. Now today the seller wants to cancel the transaction because "The Item is Out Of Stock" WHAT THE BLEEP??? How is a USED item out of stock. I refused to cancel the transaction. I am pretty sure what happened is that the Buy It Now price was suppose to be $99.99 and someone messed up so the seller thought he would just cancel the transaction. Had the item been new and then I was told it was out of stock I would have been OK with it. But how is a USED item that you took a picture of suddenly out of stock. Now he says he will find one on EBay, buy it and send it to me. I bet it is the same one that is in the pic!!!!!

    Oh. When I saw the thread title, I was expecting something a little more ... um ... probing:

    Is it safe?

    Actually, the bunch of them is more like 22grams.
    (Yes, I already have them... that's why I know they're so sharp... Ouch!)

    Ordered a couple of the 1.5gram servos. They're too cool not to have...

    May add a few 3.7grams, too.

    How many servos can a single Propeller handle?
    (Probably needs some driver or buffer circuits, too)
