Installing Unifi In-Wall Access points

The Retired Moocher decided to make the move to all Ubiquity UniFi home networking equipment. The moocher’s home network is typical of that found in a residence or small business. We have a wired Ethernet network that serves all of the high bandwidth stuff plus a WiFi network that serves the Moocher’s iThings, guests, and Internet of Things. A Netgear Orbi had been carrying this traffic with the occasional mysterious fade. Desiring more visibility into the network’s behavior, the Moocher decided to retire the Orbis and install UniFi In-Wall HD and AC access points. The Moocher describes his deployment.

Moving to Unifi USG Router

For the longest time, Apple Airport Extreme secured the Dismal Manor networks. This began back in 2002 when, out of curiosity, the Head Moocher bought an Air Port Express to add WiFi in the early days. The Moocher had noticed that firmware updates kept showing up for the Airport products so concluded, rightly, that Apple was making an effort to keep these products up to date and secure. When Apple discontinued the Airport product line, it was time to move on. But to what?

Music Discovery in the 21st Century

Are streaming services evil? For some. For others, they are the gateway to new artists, concerts, and record purchases. Audiophiles that have made the leap are in this latter camp. There’s more to life than the next Beatles reissue. Read on to learn how Roon, Qobuz, and Tidal combine synergisticly to promote artists and music. Roon 1.6 Radio is the secret.

Allo Digione gets a Face

John Darko of Darko.Audio fame asked what you hide your Raspberry Pi based audio player behind. That got me thinking. Give it a face like a Bryston Audio BDP-Pi player. Could that be done?

John was a fan of the RoPieee Linux plus Roon Bridge distribution so I gave RoPieee a try. In reading the RoPieee installation notes, I noticed that it supported the Raspberry Pi 7 inch touchscreen display. Having one lying around, I decided to add it to the basic Signature One player.

As always with DIY, some assembly is required and it is not all in the fine manual. I was using my display with an Allo DigiOne Signature HAT assembly. This HAT blocks access to the GPIO power pins. Oops — what’s the work around. Keep reading after the break.

MacOS Software Defined Radio with GQRX and RTL-SDR

Radio, like most else, has gone digital. In the early days of digital signal processing, pioneers realized that many modulation and demodulation techniques could be performed by digital computation.

As computers became cheaper and faster and integrated circuits became cheaper and faster, it was inevitable that the guts of radio receivers and transmitters would be mostly digital and that computers would do much of what went on inside new radios.

This post will describe the initial exploration of GQRX and RTL-SDR here at Dismal Manor. Most of what is already written on the Internet neglects to mention a couple of details the Moocher learned the hard way. Find out what these are after the break.

Gumby is a good gumby

I’ll try to avoid the schiit puns as Gungnir Multibit (Gumby) arrived and is settled in my audio rack. Gumby is a good Gumby! Jason Stoddard and Mike Moffat founded Schiit about a decade ago to scratch their audio design itch. Schiit has an unusual philosophy and take on high fidelity audio equipment, that it exists to serve the love of music and not to be techno-sculpture in the lounges of the rich. Rather than making a big statement piece for the wealthy, they began by making affordable $100 devices for those wishing for more than headphones plugged into an iBook. And they set out to show that you could build here of mostly US made stuff and be profitable.

Home Networks for Streaming Audio

I’ve not written on audio and networking in a while but over the holiday I read Jason Stoddard’s Schiit Happens about his return to the high fidelity equipment industry as co-founder of Schiit, a maker of personal audio and value oriented high end audio. I found the book after I had ordered my Schiit Gungnir Multi-bit DAC. Over the break I had also watched a video in which Mike and Jason (the founders) talked about how Schiit came to be and this, that, and the other thing. They are toying with the notion of offering a new product which Mike kept calling Schiit Pi. This got me thinking I should write about my streaming environment again as I had improved it significantly in 2018.
