  • So there are 3 power modes in “normal” USB; 500mA, 1A, and 2A, all three of these at 5V. The 6T can only deliver 500MA 5V.

    There is also provision in the USB spec over USBC for negotiation of power delivery that allows also changing the voltage to deliver more power. The 6T cannot do this, it lacks the usb PD circuitry.

    However, it can do org (change to “target mode” to become storage for, say, a computer to access its storage. The 6T can do this with android, but you’re right, I haven’t been able to get it to work with pmos.

    I do a lot of tinkering and development with GPS, and I use a few Blox GPS dongles. These need a bit of power to heat the ceramic antenna and atmo pressure sensor. These work with pmos.












  • These are different altogether.

    The digital code in a time signal isn’t meant for humans to hear, it’s meant to sync devices.

    The EAS is designed to be replayed on various radio systems with a simple and low-tech floor to get out there where it will be received. EAS that qualify (severe weather alerts) broadcast on NOAA’s various LF, VH, and VHF frequencies are transmitted on equipment that not only doesn’t carry digital side-channel, but isn’t even duplex.

  • So you are asking about something that seems simple, but is actually many different components working together. Apple and google have really made this integrated for a long time.

    What you want is:

    • caldav/cardav server (radicale is good)
    • integration into your email client (Thunderbird can do this)
    • share-able webDAV service
    • some auth in front of this

    I’ve left out all the plumbing needed to either support your access to this, or provide secure integration with a 3rd party email service.

    This is a hard problem to solve for self-hosting. I have a self-hosted radicale instance and I get around the inter-connectivity by simply exporting ICS files and sending them to folks. Updating meeting times, setting calendar sharing is all very difficult because of above.
