Maker Camp: Invisible Ink Printer – hack an ordinary inkjet cartidge to print in invisible ink!

2:00 pm - 3:00 pm, 07/22/2013 3E06N

Lemon juice has been used as invisible ink for centuries. Messages written in lemon juice are invisible to the naked eye. However, when heated or brushed with a mix of iodine and water, they become quite visible. We will make it possible to print any text or image in invisible ink by hacking an inkjet cartridge, and replacing the yellow ink with a special crystallized  lemon juice solution. Bring files to print out on the secret ink copier at Ithaca Generator or bring your own cartridge to be modified!
