I know this is an old thread but I just wanted to say a massive thank you!! My soon to be 5 year old wants to have a GB birthday party. So off I went in search of inspiration for his home made costume. I stumbled across this thread and I stopped looking!!
I wanted to show you my version of the proton pack and like l yours is made out of bits of old junk! Without this thread for inspiration I wouldn't have known where to start so, Thank you again for all the help this bought.
Here is a pic
Here is also a link to my How To of this whole costume.
