I'm not against the raspberry i have one , but i don't see why its so slow at times wouldn't you just be better off using a mobile phone etc to control it all i played with one for hours and really saw no reason why the big deal a raspberry over a PC or phone,  when  a good ole windows or Linux PC or  phone can do better . i even asked the dev they told kind of told me  they are some what out dated . ( raspberry that is ) . + side its a very nice learning tool.
