Happy Anniversary!

Hopefully it is a happy one... if not, you may be in trouble if you are getting a radio and she's getting something from PSA.

PSA: Don't Buy an Amazon Echo Dot

Don't buy an Amazon Echo Dot. It is a gateway drug. Now I want to buy Alexa-enabled outlets and switches. And maybe I need this battery pack, so I can move the Dot from room to room with me.

It'll cost me a few bucks up front and it will be great when it works. It also means, invariably at some point, I'll have to troubleshoot something that never fails like an outlet or light switch.

Xiaomi MiJia HT

The pictures and specs got me interested.
  • VHF frequency 136-174 MHz.
  • UHF Frequency range 403-470MHz.
  • 8 Days standby time.
  • Up to 17 hours of talk time.
  • Cost price around $35
Then I watched the video and realized it was a lot bigger than I thought. And then there was a question about the availability of English menus. Meh - wait and see.

Wireless Hacking

"His plan involved setting up a transmitter not far from the lecture (supposedly in the theater that his father, a famous stage magician, owned) that would overwhelm the signals from Cornwall. His transmitter, he claimed, was not run at full power: while it was capable of outputting 8 or 9 Amps, he turned it down to 2.5 Amps. He didn’t simply block the signal, but instead transmitted his own morse signal for a short time, claiming that he “studiously refrained from all unnecessary interference”.  
His plan worked. Towards the end of the lecture, Maskelyne’s signals were picked up by the receiver, decoded and noted by Fleming, who wrote to the Times complaining of “Scientific Hooliganism”."

I don't even know what label to apply to this. A Knoxville homeless man wants to complete a 2,000 mile trip to California with his huskies, a folding chair, and a skateboard.
