    New Product Friday: Sparkfun PTH Chick Magnet Kit.

  • Product COM-11272 | about 7 months ago

    I can’t explain how excited I am that these have been replaced with new ones at half the price, twice the LEDs.

  • Product COM-12025 | about 7 months ago

    Would it be possible to make these slightly longer than a meter? Because 64 LEDs would be such a nice number.

  • Product COM-12025 | about 7 months ago

    NO WAY.

    Twice the LEDs. For like HALF the price of the old ones you had. (at least the non-sealed ones)

    holy crap, I need to find some way of incorporating this into my halloween costume.

    You can see in the video that there’s a time display in the computer software he’s running.

    The first one I happened to notice said around 1300ms.

    So probably 1.5seconds max. Which I wouldn’t call slow, but it’s not instant.

    How else are you supposed to solder those 01005 resistors?

  • Product COM-00097 | about a year ago

    Okay, I don’t believe these are really B3F switches.

    As I said, a genuine B3F-1000 switch that I have is marked “OMRON” and “B3F”. It is the 4.3mm variety (I needed a bunch of the 5mm tall ones), with an ivory plunger, which signifies it’s the 0.98N force switch. Confirmed from here: http://www.omron.com/ecb/products/pdf/en-b3f.pdf

    According to that same datasheet, the ONLY B3F switches that have a black plunger like the switches on this page are also 0.98N activation force.

    The switches sold here take very considerably more force to press, even more than some other generic 5mm tall black-plunger tact switches that I have. These switches, although they appear to at least be made of higher quality than the ones pictured, also still don’t have the “OMRON” and “B3F” labels.

    It’s really disappointing, I bought these for the low activation force, which these switches here definitely don’t have. (and also for the 1million cycle rating, which who knows what these switches are rated for)

    Hmm, I didn’t know there was a contest!

    I should have entered my functional slot machine mask! :)

  • Product COM-00098 | about a year ago

    I popped one open, and it is surprising, there are (at least in a slightly bigger equivalent, though I would assume the smaller ones use basically the same mechanism) 4 separate moving parts and 2 stationary metal contact strips in complex shapes.

  • Product COM-00097 | about a year ago

    Also, a random B3F omron switch that I found in a drawer of random electronics things has on the bottom a label “OMRON” and “B3F” The button pictured here doesn’t have these, and also appears to be made of a cheaper plastic then the one I have (a little fuzzy around the corners)

    Are these actually the b3f-1020 switches?

No public wish lists :(
