Some of the items that are thrown away every day make the most interesting hacks. Sprites mods has come up with a controller that will operate a inkjet cartridge, check out the picture of it printing on water!

“The characters are generated based on a small sentence in the flash ROM. These are then sent to the nozzles. The sectors are made active one by one and when a sector is active only one nozzle is activated. The reason that this is done for each individual nozzle is that the print head would otherwise create a local vacuum for itself. This would result in (temporarily) no ink from the print head. By changing the nozzles, the nozzles that are not driven are given time to fill with ink again.”
