KW88 Watch

Asian watch company = no android source code

So, we're kinda on our own here.

Basics

The device comes with a bunch of wonky software on it. The important software to get is Google Play and WatchClockSkin.

Neo4j notes

Neo4j is a true graph database. Really, a property graph, but it's better than hacking graph data into other databases.

Start an instance of neo4j in docker

Note: This places the data in ~/someProject/data. If you want it somewhere else, you'll have to change this command.

docker run \

Prologue

The point of this document is to attempt to get people to stop shooting themselves in the foot by thinking a bit differently.

In any case, one of the "beautiful things" about the whole React+Redux community is they're totally okay with letting people shoot themselves in the foot. So, have at it, I guess, if you like that sort of thing...

Past Tense

There is contention on the point of treating React Action Types as things that have happened in the past.

Black Magic Probe - Firmware Flashing

The BPM is basically the best flashing tool for STM32/ARM chips. Get the hex file for whatever you're flashing (build it, download it, whatever), then follow these directions.

Install compiler

First install the arm compiler:

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa

Some useful YARD Stick One notes

This thing is a bit of a beast. People don't give it NEARLY the credit, or the documentation it deserves.

Two ways of using this thing: rfcat directly, or write a python script for it.

Basically, writing a python script is easier. Using rfcat directly is great but often, there are just too many silly settings to configure

Radio hardware input and output limits

This is a collection of maximum input and output power ratings for a random selection of devices. It's worth double checking them again to be sure...
