HPR4126: Podcasting for Newbies
My name is Moss Bliss. I'm a podcaster. This is technically my 2nd
HPR podcast, but as the first one was unintentional AND back in 2019, I
can start fresh.
I don't know much of anything. I'm a Linux user, about the same way
most people are Windows users. I have gotten more technical over the
past few years largely due to being a regular on various Linux podcasts.
I don't have sufficient education to be hired in computers (although
I've tried several times), and I did spend a few years in radio back in
my youth.
So what do you have to know to become a podcaster? Almost nothing.
Just so long as you have a computer, an Internet connection, and a
microphone. (For some shows, you may need a webcam.)
I got into podcasting by asking questions. I tried for almost 2 years
to get Chris Fisher at Jupiter Broadcasting to co-feature me, with zero
experience, on a podcast about using Linux desktops. It never happened.
So when in 2018 Rob Hawkins asked for new hosts to take over mintCast, I
was one of the first 10 or so people to apply, and one of 6 who
eventually stuck with it. All I had was a computer, an Internet
connection, and a Blue Yeti microphone my little sister gave me. Within
a few months, I started another podcast, Distrohoppers' Digest with Tony
Hughes. And a couple years later, I was asked to take over Full Circle
Weekly News. Apparently some people like my voice. Since starting my
little mini-career in podcasting, I have probably more than doubled what
I know about Linux. I'm not all that scared of the Terminal
anymore...
Some microphones are pretty bad, and my Blue Yeti was the worst one
on the show when I joined mintCast. In about a year, I found a very
inexpensive CAD Audio U29 USB mic, currently $20 at Amazon, and that
worked pretty well. Some time after taking on Full Circle Weekly News,
the magazine bought me a Samson Q2U ($60), which I'm still using. I love
this mic, as it can be used either as a USB mic or plugged into a sound
box for even better audio.
When I started, I had a T430 laptop and the Blue Yeti microphone. My
listeners and co-hosts have made my life better with new and used
equipment I could never have afforded on my own, including laptops,
Raspberry Pis, modems, routers, headphones, and even a sound box. My
current setup includes a 2016 Lenovo ThinkCentre M600 Tiny, which cost
me under $200 on eBay, a Focusrite Solo sound box (a gift from a
friend), a WavLink ST336A external goodies box (also a gift), and an old
Dynex 26" TV I use as a monitor I paid $15 for locally. I have a boom
arm for my microphone, which is made by Neewer and costs $15 on Amazon.
My keyboard is a Fellowes Microban Natural, which I need as a trained
touch typist. And I put all this stuff on a little rolling computer
desk, which I bought used locally for $25.
The only software I use is Audacity, and I didn't need to know any
more than the basics. If you're part of a team, such as mintCast, you
aren't even required to do any audio editing, although if you know your
way around Audacity you will find your skills very welcome.
If you want to start podcasting, have the equipment, contact Ken
(Note: I misspoke in the audio and said Ronnie where I
meant Ken) and do something here at HPR, which is a fairly low
entry bar, or you might contact long-running shows such as mintCast.
Participation and commitment are usually all that is required.
OK, so maybe you want to do more than produce an HPR show or join
mintCast. You have your own idea and you want to get it out there, your
own personal podcast. This is where it gets a little more detailed. If
you already have the information you need, you can stop the podcast
here, but...
First, you'll need a website or blog (if you're really broke, there
are free WordPress sites available at wordpress.com, or you could use
the dreaded Google blogs (blogger and blogspot). Other than that, you'd
have to register a domain -
HPR4125: Installing Home Assistant Operating System (HAOS), on a x86-64 machine
Introduction
This is a follow up episode on Home Assistant (HA), see
hpr4099
:: An introduction to Home Assistant (HA) for an explanation of what
Home Assistant (HA) is, and why you might want to install it.
The Home
Assistant Installation page offers several different install
methods, listed along with the level of difficulty.
Easiest: Plug and play with Home Assistant Green
Easy: DIY with Raspberry Pi
Intermediate: Extend with Home Assistant Yellow
Hard: Install on other hardware
Expert: Advanced installation methods
Today we will be installing Home Assistant Operating System (HAOS),
on a x86-64 machine.
Home Assistant can be repurposed and installed on various hardware,
such as an Odroid or a generic x86-64 machine. The Home Assistant
Operating System allows you to install Home Assistant on these devices
even if you have little to no Linux experience.
We are going to my HP t610 Flexible Thin Client, which has a 16GB
SATA Flash Drive, and I upgraded it to 16G of Ram.
Note that this will install Home Assistant Operating
System (HAOS) as a computer appliance. That means that it will run a
bare OS with the various components in a customised docker setup. It
will take over the entire computer, and requires secure boot to be
disabled.
On the HP t610 Flexible Thin Client, that involves pressing "Esc" at
boot to get to the bootup menu. If that doesn't work try pressing "F10"
just after turning on the power.
Two methods to install
HAOS has no integrated installer like you would expect with
distro
hopping, but it requires that the image be burned directly onto the
disk of the computer itself.
It has two methods to do this and "Method 2: Installing HAOS directly
from a boot medium", is basically take the disk out of the target system
and attach it to your own computer. The use a burning tool like Balena
Etcher, or dd to write the image to disk. Much as you would
burn a sdcard for a raspberry pi. I don't have a way to do this so let's
go with method 1.
Method
1: Installing HAOS via Ubuntu booting from a USB flash drive
Here you download and burn live operating system as you would if you
were
distro
hopping, the document suggests to use Ubuntu. I tried it but my HP
t610 Flexible Thin Client didn't like it. It also didn't like Fedora
despite having worked earlier, so I just used
Debian
LXQT.
https://www.debian.org/download
https://cdimage.debian.org/debian-cd/current-live/amd64/iso-hybrid/debian-live-12.5.0-amd64-lxqt.iso
Now you have Debian running off a usb stick on your target
machine.

HPR4121: RODE wireless microphones
All right. Well, good evening, hackers. My name is Clinton. And this
is a very off the cuff episode for me just to announce that I've got a
new microphone. So I just wanted to run through a couple of details of
that. Make a show, say a little about the microphone while I got it.
What I hope to do with it. So this is a roadie wireless go to setup. It
comes with three little boxes. Roughly, roughly, you can fit each one of
the little boxes inside a matchbox. So there are three of these that
come with the set that I bought. Two of them are microphones that you
clip onto your lapel. The third is a transceiver. So at the moment, I've
got the transceiver on and I've got one of the microphones on. I bought
this because I'm going to be going to a conference soon. And one of the
things that I do try to do at conferences is to interviews with people.
And this is kind of nice in that I can switch these two microphones on.
Give one to myself. Give one to the person I'm interviewing. And I don't
have to use a single microphone and shove it underneath their faces. And
I don't have to swap the microphone between the two of us. The other
feature, like the particular reason I've got this model is that each of
the two microphone units actually has built in RAM. So it will actually
record, like if you've got it set up in the mode, which I do, you can
get each microphone to do a backup recording of your presentation. The
regular mode for this set of microphones is to actually treat the
transceiver as a source and plug it into computer or plug it into your
camera as a external microphone. But it has this lovely mode, which I'm
recording this particular episode to. We can just turn it on. It's not
the transceiver is not plugged into a computer. It's not plugged into
anything. And it'll record something like 40 hours of voice. And later
on, I can hook it up to my computer as a standard mass storage device
and just download the waveform I believe. So it does have some Windows
firmware or Mac firmware. I didn't have too much fun getting that to
work under Linux. I tried under a couple of different VM products and
wasn't having any luck. So try it under wine. I tried under open box.
Eventually I did end up installing like a full Windows 10 install onto a
qemu image. And that had enough stuff working such that I could install
the Rode firmware on it. That let me do an upgrade of the firmware on
the two microphones and the transceiver because the first thing you do
when you buy something these days is out of the box you have to upgrade
the firmware because why would they do that at the factory before they
send it out when they can just make the users do that. And there is a
phone app but it does not let you update the firmware on these
particular hardware models. If I remember the error message correctly it
does look like the Android app lets you update the firmware on other
Rode microphone devices but not this particular model. So I had to go
down the track of setting up a qemu. I did find a good blog post on how
to set up a Windows box on qemu. It had a few things that seem outdated
so maybe it's a job for future me to write an updated blog post on how
to do this. If for nothing else instructions on how to do this in future
when I need to rerun the firmware update. The other thing that I really
needed to use the software for though is to switch on the recording
option. So out of the box these things do not record to the memory
that's built into the microphones. So I had to get, I had to update the
firmware and then I had to run the software on both of the microphones
to switch on the recording option. But now that that switched on I can
just hook it up as a USB master device as I've mentioned before and
presumably I can just copy the files and delete the files and I won't
actually have to run that software. So yeah there's a number of options
going forward so I can write that blog post with the updated details.
There were a number of hoops that I fo
