Can you have voice activated like Alexa
there is a PC version of alexa app available on the amazon website.
https://www.amazon.com/b?ie=UTF8&node=17549366011 i'm not sure how integrated you can get with it or how you'd configure things, as I'm a Google household. But i'm sure you could set it up to do what you would like. I don't think it's too far out of their apps wheelhouse as far as controls. it should then integrate with any other devices/speakers etc you have already. if i would garner a guess you'd just configure in the app your juke computer as "jukebox" then you'd could probably just say "Alexa play my jukebox" and it would. you'll have to see what you can do. I don't know if they have restrictions on the kinds of apps that can be run by Alexa or anything like that.
And will a hifi amp be ok to power the speakers?
absolutely. anything really. you could install a bluetooth dongle and stream to wireless bluetooth speakers... wire up a power amp to the computer's audio output for big speakers or tie it into your home theater.... the sky's the limit really.
Will have a bit play about with pc first then build the unit
Thanks again
no worries. this is the best way to go. just play around... make lots of notes. make lots of mistakes. keep backups of installs on a usb stick if something goes south on you so you can start over easily. (basically keep a running instruction sheet .... install this this this and configure this like that and connect here and done.) once you have it working how you like, you can decide what/where/how you are going to use it.
keep in mind once you start this project you might have to make sacrifices in some areas for functionality... it may even completely change the scope of the project once you get into it... don't try and shoehorn an idea into something it might not be able to be. allow it to evolve naturally. you will be more satisfied with your end product.
