Did you know? Google and other providers have large databases of geolocation-SSID pairs! By sniffing SSIDs in your area, you can get surprisingly accurate location without surprising power use. Using nRF Cloud, you can even define your own SSIDs with location--a very powerful feature for situations in which you cannot
zperf is a Zephyr shell utility modeled after and used in conjunction with the Linux iperf command line tool. If you haven't used the shell module in Zephyr before, be sure to check out Golioth's guide on using and customizing it: How to add custom shell commands in Zephyr -
Electronics design is supposed to be hard, isn't it? No longer. Let's create a 40% PCB as fast as we can with nothing more than KiCAD, Keyboard Layout Editor, and a few scripts. Let's create a fun KLE... Download it to a safe place. You'll need it. Start by cloning
Now that we've integrated somebody else's microcontroller board into a keyboard PCB, we should take a moment to learn about integrating microcontrollers directly into our keyboard PCBs. Let's walk through the important steps of schematic capture before doing board layout! The microcontroller I use for most of my PCBs is
Decoupling capacitors are a critical component for circuits that switch at a high speed. Electricity has a limited speed of propagation and, when a large transient current draw is placed on a power supply (as in a bunch of transistors changing state when you print "Hello, world!"), voltage within a
