“We wish therefore and prescribe, that all observe the law of the Church, and that at home or in the church they shall always wear the cassock, which is proper to the clergy. When they go out for duty or relaxation or on a journey, they may use a shorter [coat] which is to be black in color, and which reaches to the knees, so as to distinguish it from the dress of the laity. They should reject the more elegant and worldly styles of garments, which are found today. We enjoin upon our priests as a matter of strict precept that, both at home and abroad, and whether they are residing in their own diocese or outside of it, they shall wear the Roman collar.”
— Third Plenary Council of Baltimore (1884)

Angelus Bells and the Raspberry Pi
published 23 January 2016 by Veronica Brandt

Raspberry Pi with Speaker RASPBERRY PI is a small, cheap, British computer. Consisting of a credit card sized motherboard with usb ports, hdmi output, headphone jack and micro usb powered, it is a hobbyist’s delight with many, many possibilities. I’ll put the link to more about this fantastic gadget at the end of this article – don’t jump there yet though! I want to show you what I put together first.

I use mine as a little webserver that can be left on all the time as it is silent and doesn’t use much electricity. That’s why you can see the Wi-Pi dongle in the photo, but it’s not integral to this project.

Today I decided to use it to ring a bell for the Angelus three times a day. We are in the habit of saying the Angelus at noon, but 6am and 6pm are harder to remember.

First thing was to settle on a good chime. Searching for Carillon recordings I did find this collection, but they were all too ornate for a simple Angelus bell.

Another handy gadget I have is a midi controller. Using some synthesizer software called Grand Orgue and a sampled Carillon I was able to generate these short recordings:

    * *   The beginning of the Gregorian antiphon Ave Maria

    * *   The beginning of Sub Tuum Praesidium

Then to get the computer to run these I used a feature of most Linux/Unix systems called cron and a program called mpg123 – a command line mp3 player. There is probably a way to do something similar on other computers or even mobile devices.

These might also make great ring tones!

In the meantime, you may like to read more about the Raspberry Pi.

UPDATE: More recordings from Cologne and France
