You just saved me a big self-kick in the butt experience - for all of my ...7 or 8 Rpis I've never once tried to play a sound and completely forgot that the zero doesn't have a built-in audio output. Pi3 it is. I have considered buying one off the shelf...and still may. There's just some custom features I'd like to program in. I suppose I can always see how it goes rolling my own - Plenty of places to put that extra PI3 if I change my mind. Thanks for tips!steelo wrote: ↑Mon Nov 12, 2018 8:46 pmThe problem you're going to run into with a Pi 0 is the fact it lacks audio output and only has 2 micro USB ports (one of which is solely used to power the rpi) You may be able to use a bluetooth speaker, but I've always found it flaky wanting to connect. I'm sure after you figure these problems out, you'll notice a much longer delay with inquiries than a rpi 3. I know you're looking to use the smallest pi possible, but I would STRONGLY recommend using a pi 3 over a zero for this project. You'll still have a little sanity left after you finish
Please also note that in the end you'll probably spend more money on accessories (rpi, microphone, SD card, power supply, case, speaker) than you'd pay for an actual Alexa. I made an alexapi a few years ago with a pi 3 and although it didn't work nearly as well as a 'real' Alexa (I believe because it had a really crappy mic), it was still an educational and fun experience
AWESOME... SOLD!HermannSW wrote: ↑Thu Nov 15, 2018 11:58 am> I am more concerned with size than I am with cost
Today Pi 3A+ was released. While it has reduced RAM (512MB instead of 1GB of the 3B+), it has "all" the connectors the 3B+ has (only 1 USB instead of 4 of 3B+, no ethernet, but Wifi) and has same computational power. It is just smaller form factor and has audio connector, and sounds that it could be where you want to go.
In CPU tests, none whatsoever. In the real world, depends what software you are using. Browsing will be horrible as that's a massive memory hog. Most other apps, probably fine.
