Re: fruitbox MP3 jukebox

Hi Karrika, looks like you already got further than i could, mine does compile but only with the original MakeFile. Could you share your version of the makefile? Sure. CPP = g++ CFLAGS = -O2 -std=c++14 -D_RPI INC = -I/opt/vc/include DEPS = fruitbox.hpp fruitbox_types.hpp pages.hpp status.hpp playqu...

Re: fruitbox MP3 jukebox

I just updated the sw on my Pi4 and compiled rpi-fruitbox. I did not use static libs or the mpg123 and allegro tar files mentioned in the build directory. The only complaint was that library pthread was not explicitely mentioned so I added it at the end of the linker list. The gpio.cpp could not fin...

Re: fruitbox MP3 jukebox

The Pi4 does not create the display. But this is due to some x+++ library conflict that works with an older version but not the new version that is used in Buster. As it compiles on my laptop running Bionic Ubuntu I thought that this should not be hard to fix. Due to too little time I created my juk...

Re: fruitbox MP3 jukebox

Just a small note. For fun I compiled fruitbox on my desktop Ubuntu 18.04.3 LTS (Bionic Beaver). As it has fairly a fairly modern set of libraries I compiled it againsta dynamic libraries. I also found out that compiling for Pi4 using Buster had some library conflicts. Perhaps this Makefile could he...

Great project! I also vote for detecting snoring and breathing anomaly. Would a sensitive microphone and some clever AI filtering be the way to go?

Hi Mike, Going to make a big post but here's the mods I did to the Wurly skin for video to play between the song lists. Like you said, it's probably just a built in delay somewhere in the cfg.

Re: HDMI to VGA

HAMA HDMI-VGA cable has been working nicely with several old VGA monitors I have at work and at home. It does not have external power. But it has a 3.5mm audio output so you get both sound and video.

Re: Raspberry Pi 4 Heatsink vs Fan vs Flirc Case

I have used FLIRC cases for all my pi's. The new Pi4 FLIRC case has the same flaw as the older ones. You cannot easily use a 40-pin ribbon cable because the two screw poles are too thick for the connector. So I routinely mill away the metal all the way to the screw to fit in Black Hat3r cable. So my...

Re: Simulated novel

I assume that "Visual novel" is closer to what you are looking for.

Two years ago I found a version of Google Blocks with a Visual novel addition for some retro platforms. But I am not aware if any exist for Raspberry Pi.

As the source is available I believe the best thing would be to play video clips full screen using omxplayer and then return to the application if the video is interrupted or it ends. The MikeTV video does not work full speed on a PiZero but omxplayer does. So just start coding and make a pull reque...
