Synchronized Multiroom Audio

I've been working the last few months on a homebrew version of Alexa for my home. I'm currently installing a Raspberry Pi 3 b+ with a respeaker in every room and intended to put in Pyle bluetooth speakers. Right now, a Pi runs hotword detection on all audio it receives from the respeaker and passes ...

Re: Jessie Q&A

So, another quick question. This is a VNC question but related to how it's implemented in Jessie. I'm trying to modify the default geometry of the realVNC server and, for the life of me, can't get it to work. I've tried creating a new config file in /etc/vnc as well as modifying the existing one. No...

RF communication while using a hat?

So, I'm currently working on a robot that uses stepper motors but I also require it to communicate via RF with an Arduino nano. As of right now, I am currently using the Adafruit motor hat to drive the two steppers. The issue I'm running into is that I have this hat sitting on my GPIO pins and I als...

The last release was 23/09/2016 and Raspbian Jessie has regular updates;

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade
That ended up being exactly what the problem was. Thank you!

Have you done a package update recently? This sounds a lot like an issue that was fixed just after the raspbian pixel release.
I installed Jessie yesterday, would the package update not be included in the recent build?

Re: Jessie Q&A

So, I updated from Wheezy to Jessie and I was really excited to see that it already had VNC baked in to the distro image. That said, I've been having a lot of issues with getting it to work properly. I've enabled VNC in RPI configuration but I find that it's not actually running on start and I'm not...

Re: Some advice on car automation

I'm going to be placing a 7 inch screen where the controls currently are as an inboard interface (I hope to later use the pi to control the car computer for quick select of presets for fuel efficiency) and so I'm going to recess the controls and attach position motors so that I don't need to deal w...

Re: Some advice on car automation

I think my first thing to check would be the voltage and amperage your glove box light draws. Couldn't even begin to tell you if it's enough or stable enough to power a PI but it's certainly an idea. Out of curiosity, why go to the trouble of controlling the heat controls with motors? I mean, it sou...

Re: Running the Alexa Voice Service on the raspberry pi?

Are you looking to actually run ASK on a pi? I've seen a number of people ( https://github.com/armzilla/amazon-echo-ha-bridge ) use a R Pi to emulate a Phillips Hue Bridge and communicate with their Echo. They were mostly doing things like home automation but I also saw a number of robotics applicat...

Thanks, I'd wondered about dongles. I had heard a couple complain about using them with the pi and was looking at adafruit's FONA but I'm all for cheap and easy.

Flying quadcopters over GSM

So, I've been working on a project to connect my quadcopter's ardupilot with a raspberry pi via MAVlink. The ardupilot is a great little controller with extensive autopilot features already programmed in but I'd like to use a raspberry pi to be able to gather sensor data as well as receive GPS waypo...

Re: Raspberry Pi/ArduPilot Quadcopter

There is actually pretty good documentation on how to do this. http://dev.ardupilot.com/wiki/raspberry-pi-via-mavlink/ I would like to know how this is going? I'm looking at doing something similar. I want the raspberry pi to receive GPS coordinates via GSM and pass them through MAVLINK to the ardup...
