The pyDeco system is an opensource descompression system wrote on Python programming language there will be 4 phases [phase 1] Generate a simple Nitrox calculator for reacrational divers that will calculate Maximun Depth when user inputs percent of O2 on the mix following rule: ((maxO2PressureOnTheDive/mixO2Pressure)-diveAbsolutePressure)DephtEquivalantto1Atm Calculate the Air Equivalent Depth when using Nitrox AED = 1-PPO20,79 [phase 2] Generate a deco system using the algorithm found here http://www.lizardland.co.uk/DIYDeco.html [phase 3] Preapre a webservice using the software on the phase 2 [phase 4] Integrate more descompression algorithms
