the problem with that is where do you put the laptop
not saying it cant be done but will be difficult as usualy u have to find an extension for the panel wire
i dont know much about using a laptop for the pj. (other members on this forum can help with that)
however i have never seen one since i have been a
member , so that tells me it must be impracticable
you can sometimes pick up a 15" kit or even a 12" kit fairly cheap from the trading post
but do be advised , this will prob be the most expensive part of your pj .
it is the one part that is imo worth the money . especialy if this is your first pj
