All things me.

With inspiration from the excellent The Stock Pot, and in particular the full tutorial for how to Make Your Own Universal Remote (ESPHome + Home Assistant), I’m slowly starting to wrap my head around Home Assistant and ESP8266/ESP32. I’ve managed to wire up a button to my ESP8266 and I can register single, double, or long presses on said button in Home Assistant.

There is a lot more work to be done in Home Assistant itself before I can get anything proper out of this, but I’m making progress and having fun.

I’ve recently gotten myself a Home Assistant Green. Up until now I haven’t used it for anything in particular. My smart home consists almost exclusively of IKEA stuff at the moment and as long as I keep it that way the Ikea’s own app works fine. I would like to be able to add stuff from other manufacturers though, so that is why I got the Home Assistant and will slowly migrate over to using it instead.

Right now I’m reading up on some ESP32/ESP8266. I would like to make my own simple home automation hardware and this seems like the way to go. I bought a cheap ESP8266 board the other day and I think I’ve managed to install ESPHome on it. It shows up in my network logs so it seems to be connecting to wifi. I’m considering this a successful first test and I’ll keep playing with this more in the future.

Some awesome things

This is just at quick post to share some awesome robotics stuff on YouTube.

Yesterday I took a long walk with Iris and while she slept I listened to a whole bunch of episodes of the silly podcast Robot or Not?. It’s really silly, and funny, and great, and if you have any interest in the Incomparable and/or Jason Snell or John Siracusa you should listen to it!

Anyway, all their talk about robots got me thinking about BB-8 and the fact that I kind of want to put a BB-8 toy on the wish list for my 30th birthday. Still, it’s a really expensive toy considering that the main thing I’d probably have it do is patrol back and forth through my house. So instead I started thinking about building robots, which led me to YouTube.

First, I found this great of how the BB-8 toy works wherein a guy who build robots for fun, and who has built and R2-D2, takes a BB-8 toy apart and shows how it works.

Then I found a video of a guy who’s building his own BB-8 from a globe, and RC car and some other stuff. Inspiring idea, and I love how he walks us through his work.

I then took a closer look at the guy behind said video and he seems to be simply awesome! He builds all kinds of cool geeky stuff. How about an actual ion propulsion for a TIE Fighter toy? Check this guy out!

And finally, as I made my way out of the BB-8 hole and towards the Arduino based robots I’ve seen before I found this guy, Kid Robot Maker and his video about how to make a cheap Arduino robot. This kid is my new hero!

The robot he builds is excellent in its simplicity and I love how this kid, who seems to be really young, just throws himself out there to the world and sort of says ”hi, let me show you something awesome”. How come I, who are probably at least twice his age, never seems to be able to work up the courage to do a video like this of some simple but cool project.

Kid Robot Maker, you’re the man!
