Given your inexperience and the fact that you can continue working on the project on the side (make sure that is in any employment contract you sign, explicitly called out) I personally think you should take the job. Use it as a learning opportunity and keep moving forward on your side project.
One other note: why is your own project taking so long to develop? Is it possible that you need to reduce the scope so you can launch sooner? Just some thoughts.

It's a really big project involving hardware, not a web-only startup ;)
