Easy DIY Fully Addressable RGB LED Strip with ESPHome or WLED

FacebooktwitterredditpinterestlinkedinmailFacebooktwitterredditpinterestlinkedinmail

In my last post about flashing a cheap LED controller, I mentioned that method is only really worth it if you already had the strip or the controller already laying around. However, if you wanted an LED strip project from scratch, I would highly recommend that you just create an addressable LED strip. It will cost almost the same, it is actually easier to do, and it will give you a lot more control over the strip. And I don't know if it is the strips that I got, but the color from the addressable strip seems be a lot nicer than the dumb strips from my last post. That could just be because the LEDs are closer together.

Using the WyzeCam as a Webcam for Your Computer or OctoPrint

So if you are looking for a webcam right now (I am writing this article during the COVID-19 pandemic), then you might discover that you are literally going to spend about 3 times the normal price. The Logitech C920 costs $200 right now, and the popular budget C270 will cost you $100.

You can currently get popular WiFi WyzeCam for around $25. And even the pan/tilt version for $35. However, those cams are WiFi only, and won't work out the box with your computer as a webcam for video conferencing(or for OctoPrint, which is what I plan on using it for). However, Wyze recently released a special firmware that allows that function.

Summoning Actual Fire, or Other Automations, When the Bomb Goes Off in CS:GO via Home Assistant

A few years back, I wrote about integrating my dumb gas fireplace into Home Assistant using a Wemos D1 Mini. A few weeks ago Github user locii created an integration for Home Assistant that lets you integrate the popular PC game, Counter Strike: Global Offensive. So I figured I need to combine these things, and summon fire when the bomb goes off in the game. This article walks you through setting up something like this.

Here's a link to a video of it in action.

Updated FilaWeigher Filament Scale – Now with Temperature, Humidity, Pressure, and MQTT

As I talked about in my last post about the FilaWeigher, I wanted to add MQTT and temperature/humidity(Using the BME280) to that project. Well, I've done that. Refer to the previous post for more details. But now for this one, I'm just going to focus on the updated code and schematics, and the Home Assistant integration via MQTT. I'm going to leave the old post up for the people that don't want MQTT or the BME280 sensor. This version also has JSON output of all the sensors which allows for OctoPrint integration(I actually just finished up that plugin and I'm going to be posting that up soon).

The FilaWeigher – A Standalone WiFi Web Based Weight Sensor for 3D Printer Filament For Less Than $7

I created this project so I can know exactly how much filament is left on a spool for my 3D printer, an Ender 5 I wrote about previously. However, it can very well be used to weigh anything else. I put a few settings that are specific to the filament, but they don't have to be used.

Using a Kindle Fire as a Touch Screen Home Control Panel

Recently, Amazon was selling the refurbished Fire 7 tablet for less than $40. The new one runs for juts $10 more. So I figured I would order it and see if it would be an option. After spending an hour with it, I felt confident that I can make it work. I’ve been running it for a couple weeks at the time of writing, and it’s been awesome.

Using the Xiaomi Aqara buttons with Home Assistant via Zigbee2MQTT

FacebooktwitterredditpinterestlinkedinmailFacebooktwitterredditpinterestlinkedinmail

I had recently put Sengled Zigbee bulbs in my nightstand lamps to pair with Zigbee2MQTT on Home Assistant. I was using them to automatically turn the lights off/on when playing/pausing a movie on the TV. However, we found ourselves cutting power to the night stand to turn them off since pulling out our phone to turn them off was too much of a hassle. So when they had no power, the automation for those bulbs wouldn't work unless I manually turned them back on. Not an ideal situation.
