Re: playing an audio clip remotely

This is really simple to code in Java. Does that work for you? I've written a Java interface to pigpio that will make it all doable in pure Java. You can take a look at my website http://knutejohnson.com/pi. If Java is fine for you, make sure you have openjdk11 installed. $ dpkg -l | grep openjdk-1...

Re: playing an audio clip remotely

If it works in one direction we should be able to make it work in the other too. Is the mp3 file of a long duration or is it just some short (less than a few seconds) message? Do we need to actually send the sound file or can it be stored on the Pi? I don't know much about adhoc networks but I'm as...

Re: playing an audio clip remotely

just the one button. and one sound clip in mp3 format. Will it change anything code wise if I wanted this process to work either way? like both pi's have a button and can trigger the sound on the other pi.

playing an audio clip remotely

Are there any experienced Pi-grammers that can help with a simple project? I want to press a button on one pi and have a sound clip play from another pi.

Re: can a direct (private) network be setup between 2 raspberry pi's over wifi?

Im not all that worried about performance as it will only need to transmit the necessary data to command the remote pi to play an mp3. Now that I know this is doable now i just need to figure out the code needed to press a button on one pi and have it send the command to the other pi to start an mp3...

Re: Raspberry pi 3 for emulator

Absolutely not. The pi3 is capable of running up to PS1 and N64, both of which have several games that run at a low frame rate. As a general rule you need a computer with about 4x the specs of the system your trying to emulate. The ps3 specs are 3.2ghz single core processor, with 256gb ram. So you w...

Re: Another RetroPie user in need of help.

What install tutorial are you using? I see several commands typed in that I don't remember ever having to type. And in my experience updating packages is completely automated. You shouldn't have to type anything.
