ZiPPMac the Zilog microcontroller-powered polymerase chain reaction (PCR) machine Reinald R. Cruz. 2007. vii, 54 col. ill. + 1 computer laser optical disc. Thesis (B.S. Computer Engineering)--University of the Philippines, Diliman. PCR or Polymerase Chain Reaction is a technique used in multiplying and amplifying DNA in a short period of time. Automation of the PCR process is done by PCR Machines or Thermocyclers. Currently, many PCR machines exist in the market varying in well-block capacities and having different features such as programmable cycles, program memory, and PC interface, but they cost 000 at the cheapest. The ZiPPMac Project developed a small-size, low-cost PCR machine. An alternative that is comparable to PCR machines existing in the market in terms of functionality and accuracy in thermal cycling and the PCR process. ZiPPMac made use of a Z8 Encore! Microcontroller and utilized thermoelectric modules (TEM's) as the primary heating and cooling element. The microcontroller was programmed using ZDS II. The temperature was controlled using pulse-width modulation and a digital PID controller embedded in the microcontroller's firmware. An LCD matrix was used to display the machine's status and operation. Keypad, switches, and push buttons were used for input variables. Being cheap and small sized, it will greatly benefit researchers and students in the field of biology, medicine, and forensic sciences. With the ZiPPMac project, students and researchers would be able to purchase a machine at a much lower cost, if not create their own PCR machines, so that they can have better learning and be more enabled to do their research works anytime, anywhere.
