I have an HDHomeRun HDHR5-4US which i reviewed, and I generally love it. However, about a year ago I moved to a “new” house and the previous owner left all the TV’s that were wall mounted. All were fairly old TV’s and none of them smart. I hooked Roku’s to all of them.
That is when the trouble began. I installed an attic antenna and got good signal strength, and symbol quality on the channels that were important to me. I could watch those channels WITH NO ISSUES on my phone or on my laptop. The old Roku connected TV’s were another issue altogether. The channels would pixelate horribly and the stream would fail frequently. I have super fast internet and the TV’s are all close to the wifi router as well with great signal.
I really believe it is a transcoding issue with Roku. Or rather the fact that Roku does not transcode. Again, it works on my computer, phone, and Firestick devices work fine.
So, to mitigate the problem I bought a new TV for the Bedroom. An LG 43UQ7590PUB from BestBuy. Before I bought it I confirmed the LG WebOS had an HDHomeRun app. However, when I got home there was no app in the LG store. Previous WebOS versions had it available. I contacted LG Support and they told me to hook up a Roku!
xTool Infrared Laser Focusing
xTool IR Module
I purchased one of the xTool Infrared Laser modules and while it is super cool there does seem to be some internet chatter that the manual focusing mechanism is not 100% accurate.
There is a flip down bar that positions the laser 20mm from the work surface however the optimum focal range is 1mm or less. That means even a tiny positioning error can greatly reduce the effectiveness of the engraving operation.
There are a few strategies for manual focusing the module however the best of the bunch in my opinion is to use a USB microscope to visually dial the beam down to the finest possible size.
I purchased a USB microscope from Amazon a long time ago for my first laser I owned and had to knock the dust off of it. Set up is easy however software doesn’t really exist but the microscope works fine on a Mac with QuickTime Player. It used to work with Photo Booth but doesn’t really seem to anymore. It takes one still shot and then disconnects on my M1 Macs.
Aim and Observe
I wish I could give some kind of detailed, highly technical steps but the reality is that you just aim it at the laser dot, hit fire, and move the xTool Infrared Laser Module until the beam is the smallest you can get it. You have now achieved optimum focus. Here is a video for clarity.
Th, Th, The…..That’s All Folks!
Looks like either today or tomorrow John’s Tech blog will flip the counter over past 1,000,000 hits.
I started this web site to document my projects. In the computing world and especially the Linux world people who have years of experience often forget they are trying to communicate to newbies sometimes.
My approach was just to simplify things and to document the process FOR MYSELF so I could redo it in 6 months or a year later when it broke.
I BASICALLY MADE THIS WEB SITE FOR ME AND IT WAS ALMOST A JOKE TO CALL IT JOHN’S TECH BLOG.
And here I am almost a million hits later.
This isn’t Technical per say, but auto service centers are technical workplaces. Mostly I’m documenting this in one place so I can point Toyota Customer Service folks to the story so I don’t have to write it multiple times or tell it on the phone. I’ll try to keep it factual.
We all know what 3 way switches are even if we don’t know what they are called. It is a light that has 2 switches, like at the top and bottom of the stairs. What I did here was to wire up two smart switches that are not 3 way switches in a 3 way configuration.
FIRST OF ALL LET ME SAY THIS ISN’T MY DOING. I HAD TO HAVE MY HAND HELD DURING THE ENTIRE CONFIGURATION OF THE SWITCHES BY THE COMMUNITY AT DIGIBLUR’S DISCORD CHAT ROOM. THEY ARE THE GENIUSES. I’M MERELY DOCUMENTING THIS PROCESS FOR POSTERITY.
If you have any interest in Home Automation be sure and check out the YouTube Channel of Digiblur and his Discord chat room. Great resource. Let’s get to the switches!
I’m a big proponent of fixing stuff rather than replacing it. The “new” home I moved to has a built in audio system in a lot of rooms and on the front and back porches and even a speaker way out in the woods on a deck.
The speakers on the back porch are all fouled up and only produce sound from the tweeter. The outdoor speakers are all Polk Audio Atrium55’s which are discontinued.
Polk Audio Atrium 55
So, as luck would have it, so are the replacement speakers ( Part Number RD0756-1). Can’t find them anywhere.
The successor to these speakers seems to be the Atrium 5’s which cost $250 at Amazon, Best Buy, eBay……….everywhere.
So let’s see how I deal with this………
I have a real cool LED strip that I installed a while back. Details of that build are here.
My Living Room Arch LED Strip Installation
I just built a work/hobby room up and decided to put some effect lighting in there as well. I did a little research and of all the LED lights that you can buy in Lowes, Target, Walmart, HomeDepot only the Monster Smart Illuminessence lights line at Walmart seemed to be available quickly and they seemed to possess the ability to be flashed by an Open Source Firmware called Tasmota.
Yep. My blog. I can say whatever I want. The Ring Doorbell platform is a piece of fucking shit.
I had a Ring Doorbell for a couple of years and it would intermittently die, would not connect to a live stream if I got a notification and would die for days only to come back to life mysteriously.
So brilliant guy I am I bought another one to replace it. A Ring Doorbell Pro. It is two wires and an app connection yet somehow it took me two hours to install and I’m a geek.
It’s a piece of fucking shit. When it did finally install after I found an obscure reference in their forum that said to turn off cellular data on the phone while installing it was hit or miss on live view.
I got a hair emotional when I wrote this😃. I’ve edited to add a fact or two but my review stands mostly as is.
Yes Uniden makes a GPS kit for their scanners. It’s $80. You can DIY one up for less than half the cost. And it’s fun to make your own stuff and you’ll learn a thing or two as well.
Here’s what you need.
