    Z Nope

    I was excited to start setting up the Z-Wave bridge. That excitement has dimmed. I’m got the device in the mail, whipped out the installation instructions, plugged it into my Pi and… The first step was to run a curl command to a http site and pipe it to sudo bash. Eeek. I mean I know people joke that the “S” in IoT is for “Security” but this wasn’t funny. I’d never ever do such a thing on a device and trust that device again. I proceeded against my better judgement to see how far the rabbit hole went. (I’ve since disconnected the Pi from the Ethernet and will reflash…

    A Photogenic Z-Wave Bridge

    We’re moving away from Z-Wave tech and investing more deeply in Apple HomeKit. Part of that will include using a Raspberry Pi to act as a Z-Wave bridge until we (eventually) replace the Z-Wave devices with devices supported by HomeKit natively. And because it would be boring just to plugin in a headless Raspberry Pi, I decided to have it do double duty as a digital picture frame using a neat little touchscreen by EVICIV. This article covered most of the setup needed to use feh and xscreensaver, although I did need to do one tweak, probably because I am running a relatively new version of Raspbian (Raspbian GNU/Linux 10…

    .NET 5 + Blink an LED

    Microsoft announced the release of .NET 5 today… and included an example with the quintessential “blink an LED” that is the Hello World of the embedded IoT space. Can’t wait to try it on one of my development boards. https://devblogs.microsoft.com/dotnet/announcing-net-5-0/ https://github.com/dotnet/iot/blob/master/samples/led-blink/Program.cs

    Projects… In Progress

    I’ve added a link to my most recent project… which is still in progress – it is an IoT weather station I started developing as part of my MSEE at UW. So happy to be working with embedded devices again. Check out the Projects link in the menu above to learn more. I’ll be adding more media and details to the repository Wikis soon.

    Azure Sphere

    Microsoft is making in-roads into embedded devices in an interesting way – this walkthough was released just last week. Time to order some more hardware 🙂
