Cellphone hacking is nothing new but this hack for medical purposes is simply imposing. Scientists at the UCLA have transformed a Sony Ericsson phone into a blood testing unit, which can detect HIV, malaria and several other illnesses. This portable blood tester was created by just using an LED, a plastic light filter and some wires. The hacked device analyzes the blood cells that are placed on an integrated off-the-shelf camera sensor and lit up with a filtered light source. Pictured above is an off-the-shelf Sony Ericsson cellphone that has been modded into a LUCAS imager. LUCAS stands for Lensfree Ultrawide-ﬁeld Cell-monitoring Array platform based on Shadow imaging. More images for the hacked phone after the jump.
