Further Adventures with Music on Raspberry Pi

Posted on 11 June 2023 by matthannan

I have a Raspberry Pi 3B (not the Plus version) with a HiFiBerry Digi+ DAC HAT attached. This is connected to my old school Sony receiver via TOSLINK fiber. I also have a 10.1″ touchscreen attached. The goal of all of this was to build a digital jukebox to play my music collection through.… Read the rest

Posted on 5 November 2022 by matthannan

The original guide shows the build using the ESP8266 board. While there is nothing wrong with this build, the ESP8266 does not have built-in Bluetooth support, which is all the rage these days.

Posted on 31 August 2022 by matthannan

Forecast for the day is a heat advisory. If we haven’t already been under one, having one today was really bad news. I took advantage of not being able to work out in the yard to get caught up on the checking account and paying the couple of bills that were sitting on my desk.… Read the rest

Posted on 8 July 2022 by matthannan

I just bought a thing.

It has been a refresher lesson in Intel CPUs for me, as well as a revisitation of what my financial pain threshold is. Even this ($288) is a bit above what I wanted to comfortably pay, as I need to drop more RAM into it.… Read the rest

Like Frankenstein’s Monster, Just Zap It With Electricity

Posted on 19 January 2022 by matthannan

Electricians are arrived at the house at about 8:00AM. Told me it’d be about four hours to install the 240-volt from the circuit breaker panel to the outdoor heat-pump. They were done a touch past 10:00AM.

I turned the Nest thermostat, which drives the oil burner, down to 58F and ran around setting the head-units to 66F.… Read the rest

And the Next Day, Mini-Splits

Posted on 17 January 2022 by matthannan

Everything happens at once. Yesterday we took down a 75′ spruce tree, and today they started installing our ductless mini-splits.

Today, they installed the four head-units, the backer plates for the exterior channels, and the pad for the outdoor compressor. Tomorrow they install the line sets and hopefully the outdoor compressor.… Read the rest
