Easiest Mic/Speaker option for Raspberry Pi 3?


#21

We have noticed an issue with the raspberry pi analog audio. Even using aplay repeatedly can cause a hang.


#22

Yes I was using an analog audio speaker and it hangs … will try changing to hdmi with rasp-config


#23

I got a PS3 eye camera for less than $6. Works almost too well… it catches speech from the TV across the room.


#24

It is HIGHLY directional.

Hi Karl!

I have a question, does mycroft (the software) work together with https://creator.matrix.one/#!/index ?
Any place I found a similar question, as here above me or on the creator.matrix forums, the question stays unanswered. Is it in someway a “stupid” or “immodest” question?


#26

Hey!

As of now, I’m not sure. I don’t know of anyone having done so yet. I also don’t see any reason why it wouldn’t work. I think it has been done, but can’t find any info on it.

I do really like it. I’m also thinking about pre-ordering the Matrix-Voice as that would definitely put the hardware on-par with an Alexa or Google Home.

Update: I totally pre-ordered the Matrix Voice. I’ll probably post something cool whenever I get it. (May?)


#27

Matrix Voice looks very interesting project … a cut down Matrix-Creator board losing temp pressure etc to lower the price.
This pimori speaker Hat board would be great a Mycroft speaker … and the led display could indicate Mycroft status. out of stock however.


#28

I bought the SpeakerpHat and haven’t gotten it to work yet out-of-the-box. Granted, I’m not a schooled coder, but the “picroft” doesn’t recognize it. Getting this error after running Pimoroni’s install script:

ALSA lib pcm.c:2239: (snd_pcm_open_noupdate) Unknown PCM cards.pcm.modem

Thoughts?


#29

Hey did have you had any success with the Speaker pHat and picroft? I’m having the same issue and can’t seem to find any way to fix it.


#30

Not yet. I figure I have to start over with Rasperian and install Mycroft on that. Picroft seems not to work with SpeakerpHat for reasons I am not nerdy enough to debug.


#31

Anyone with info on Bluetooth setup it, pointers/external references would be appreciated! We’re lacking it in the wiki.

People on slack have found that the matrix.one is currently INCOMPATIBLE with picroft.


#32

I’m using a cheap Adafruit adaptor with a cheap electret microphone capsule.

Mycroft certainly responds to questions if I stand 3m away, although as my man-cave is quite small, this means I’m standing outside the room in the hallway. Not bad!

I’m not using the audio out from the Adafruit (I have a seperate amp/speaker on my rig) but I’m pretty sure this could also be made to work.


#33

From where should I give audio input. Is it from my phone through which I connect to wifi MYCROFT.


#35

Did anyone try this speakerphone/mic combo from Hamlet? It’s quite cheap (around 10 euro) and it should be supported under linux (from the windows drivers I see it uses a CMedia CM106/108 chip).

I use the Google AIY voicehat. It also includes a button.


I made a diskimage for it that works out of the box, and that updates with the regular picroft updates,

Just finished designing a custom enclosure that will be printed next week.

#37

What 3D tool is your customer enclosure designed with. Where can I get the native CAD and STL files, if available?

This is for the v1 voice kit, as pictured in your post, right?


#38

Hi there @urbite - the Mark 1 printing files are at;

Is this what you were looking for?


#39

Actually, I was looking for tjoen’s custom enclosure for the Google AIY kit. This was referenced in the post prior to mine. But thanks for the Mark I links, they will be a good starting point for other designs.
