  • Product COM-12710 | about a month ago

    The datasheet notes that the letter designating the intensity is on the “hack side of the package”. Leading to the obvious question: What are the other sides?

    <hint>I can not find the sign: neither by looking under swag nor by searching (tried “bag”, “dog”, “poop”, and “sign”).</hint>

    (edited grammar for!)

  • Product DEV-12654 | about 4 months ago

    “NoIR” meaning “black”, not “NoIR” meaning “No InfraRed”. For any other confused shoppers out there who have missed either their morning cup of tea or their lesson on the names of colours in French. (Took me a couple of readings to figure it out this morning.)

  • Product COM-09456 | about 4 months ago

    How bad of an idea is it to use this with a pair of zener’s and a high side current sense resistor? I’m guessing if the zeners match right (is that hard to get?), then they could keep the high end of the differential voltage under the Vcc-1.5V ceiling of this op-amp and allow current control with an uninterrupted ground line.

    (Comment “deleted” since it was posted on wrong product.. it was meant for the op-amp tat this product uses.)

  • Product PRT-11476 | about 4 months ago

    How many amps can this handle? I would like one that has some headroom on the specs, and my current projects call for 3A at 14V and 1.5A at 22V. I’m blinking LEDs bright enough to embroider by.

    (And why is the only documentation link a video? This fine morning there’s no datasheet link, and I’m at a computer without flash so I can’t watch the video. )

  • Product PRT-00119 | about 4 months ago

    New design? As of the end of 2013, you want product 10811 instead.

    By the datasheets product 10811 withstands higher voltages and currents, and by the product description it has the additional capability to be used on a breadboard prototype before you solder it all down. As annoying as it may be to post a product discouragement here, this here is a distracting product: it does less of the same thing as 10811 at a higher cost. The newer product (this one is 119 - from much earlier in Sparkfun’s history) appears significantly better.

    I’m pretty happy that Sparkfun chose to add the better one when they found it. Thanks! Now, retire this one, so we don’t have the Mouser/Digikey/Farnell/etc “How many datasheets do I have to read to pick a jack/resistor/LED/bananaphone/transistor/wire?” problem. That’s a yak I don’t want to shave.

    But! - If you already have a pcb, and it need this footprint, then this would still be the right one.

    If I missed any other reasons why you’d prefer this over the other one, please correct me! People buying the wrong product for what they need is sad. : (

    The original Cerberus is listed on the Sparkfun originals page, but not the newer one with the inbuilt hub. So only the old one is discounted.

    The distinction does seem a bit odd.

    When the engineers are cold, if they can’t find the thermostat they find a work-around. If they can find the thermostat, they find a work-around anyway.

  • Product PRT-12590 | about 6 months ago

    Finally! The correct header style for wearables with FTDI-compatible programming: both low profile and no snagging.

No public wish lists :(
