Brilliant !!! Well done man !! I'm working on a patent now for years (food catogary),but my problem with this is that I don't have the resources at home to make a sample or demo of this particular patent,this was always a question for me,did you make your first demo at home,did you just take the idee to someone else to fabricate a few samples,or how do you do it.I will appreciate it if you can give me some advice here.I have a passion for new inventions and this is defnitaly a winner,good luck !
