Here’s an interesting method for making a home made copper based conductive ink for forming circuits on paper, plastic substrates that is pretty easy and inexpensive and has fairly good characteristics – well when it comes to home made inks it does! – that you can try. Sorry about that it’s a poor microphone – it’s integral to the camera and not very good! Anyway, you need ascorbic acid (vitamin C) – 5g, Copper Sulphate – 1g and water at 70C – approx 200mL to make the solutions and a few drops of gum arabic to make the paint (this is sold as watercolour medium by art shops)
