  • Product TOL-10214 | about 2 years ago

    If D+ and D- are shorted, it signals that it’s a “dedicated charging port” with more than 0.5A available but no data connection.

    Seeing as the other end of this unit is 120V A/C, it doesn’t make much sense for it not to be a DCP port - other than that it has a 0.5A rating on the supply side anyway. Rebuilding it with the internals of the 1A unit and shorting D+/D- to create a DCP would be a great upgrade.

    Nominal current is 0.667 A at 3V. Not sure how this will work if underpowered but you probably want to take a pass on the 500 mA supplies.

  • Product TOL-10214 | about 3 years ago

    Off the top of my head, isn’t that meant to signal that there is more than 0.5 A available for charging? Even if it’s implemented here, there’s still only 0.5 A available.

  • Product COM-10541 | about 3 years ago

    One digital pin and a 555 timer.

  • Product BOB-10160 | about 3 years ago

    See the DS3234 datasheet. It likes Vcc = 3.3V but will also take 5V.

  • Product BOB-10160 | about 3 years ago

    Somehow, the ChronoDot has been out of stock every time I’ve checked. I’d have bought several and recommended more by now if this wasn’t the case.

  • Product DEV-10083 | about 3 years ago

    In general, you can solve that sort of problem with a boost converter. But the LilyPad has a minimum operating voltage of 2.7V. I would endeavor to stay away from the minimum, but there’s no reason that a 3.7V battery can’t do the job (to some reasonable level of discharge).

  • Product WRL-10393 | about 3 years ago

    I was just looking at the pins for this and the Arduino Pro Mini 328. If the illustrations are correct, it doesn’t look like the pins actually match up.
    This: GND, CTS-I, VCC, TX-0, RX-I, RTS-0
    Mini: GND, VCC, RXI, TXO
    It would be nice to be able to use the Mini instead of the LilyPad since the result should be a bit more compact.

  • Product COM-10805 | about 3 years ago

    Awesome, these can be great for usability. I look forward to trying them.

    The materials are likely to degrade before they wear out. They should be debounced, but they shouldn’t be excessively bouncy unless you’re using an under-strength magnet.

No public wish lists :(
