Birdhouse Alarm Clock

This is part of a Chrsitmas present for my wife. The only use I think others will have for it is as a source for examples.

She had a Grace Digital Mondo that was a fantastic alarm clock for her. They quit supporting it and most of the features were shut down. She had a very detailed set of features she wants in an alarmclock. There was nothing in her list that I didn't think I couldn't code myself with a little effort.

Back in the last 1990's and early 2000's she made a lot of folder icons and desktop wallpaper. I thought it would be cool to repurpose these for this project.

While trying to think of how to build the case, I had the idea of a birdhouse, using her bird icons for the GUI.

Parts

Raspberry Pi 5 Raspberry Pi 5, absurd overkill, I wanted power for future expansion. I have ideas...

HiFiBerry Amp4 35W is plenty of power for this. I like the ability to have a single power supply for both the amp and the Pi.

Power Supply Recommended by PiShop.us for use with the Amp4

5 inch touch display My first DSI display. Seems good.

Dayton Audio PC105-8 4-inch full-range driver Selected because Microcenter had it in stock and the size was right. Sound quality is adequate but not great. Maybe it'll be better once the enclosure is finished.

I used a small microsd card, there is no need in my usecase for a big one. I bought a 128G Microcenter branded one with the Pi and speaker, but it was defective. I've not returned it yet because I'm lazy and it was only $10. I've never had a problem with Microcenter cards in the past, so I'm assuming this is a fluke. Why am I telling you this? I don't know. I don't know!

Need to add

RTC clock battery, obvious reasons.

Glitches & Hitches

Once, after disassembling to test fit, the touch on the display quit working. After a few dis/re-assembling and moving from DSI-1 to DSI-0 it started working again. I think it was just underpowered and needed a bit to warm up. Or, it needed the speaker connected, I don't know. I've not gone looking to recreate the issue.

Setup

use raspi-config to switch to Wayland / labwc

install go

Install the code go get github.com/cloudkucooland/AlarmClock/cmd/ac

edit /etc/xdg/labwc/autostart (should use $HOME/.config/labwc/autostart but I did what I did)

/usr/bin/lwrespawn /home/scot/go/bin/ac &
/usr/bin/kanshi &
/usr/bin/lxsession-xdg-autostart

set up for mono

pactl set-default-sink 37

Code notes

This is my first project using ebiten or using a game engine at all. It has been fun. I'm learning a lot and now have the urge to write and 8-bit-looking RPG...

GPIO Pins

HIFIBERRY AMP2, AMP4, AMP4 PRO

  • GPIO2-3 (pins 3 and 5) are used by our products for configuration. If you are experienced with I2C, you might add other slave devices. If you a a novice, we don’t recommend this at all.
  • GPIOs 18-21 (pins 12, 35, 38 and 40) are used for the sound interface. You can’t use these for any other purpose.
  • GPIO4 is used to control the MUTE function of the power stage. Pulling it to low will mute the output.

Adafruit NeoPixel

  • NeoPixels must be connected to GPIO10, GPIO12, GPIO18 or GPIO21 to work! GPIO18 is the standard pin.
  • Looks like GPIO10 (pin 19) are GPIO12 (pin 32) are my options
