For so many things in your plate, I'd suggest you split it by days, rather than doing a bit of everything every day. I'll asume you work Monday thru Friday, so that's a big constant. You could either do Work + Learning on the weekdays, and work on your side project on the weekends, or the reverse. Since the subjects you're learning are quite dense, you might benefit from studying an hour or two every day. Or it might be best to leave those for the weekend if you're bent on finishing your prototype in a short timeframe. I suppose the real answer here is trial and error. Everyone is different, but you could try two or three different combinations and figure out which is best for you.
