Ohminous is a project mainly written in Objective-C, it's free.
Semester One 2011 iPhone App for BCT
OHMINOUS is a simple 4 band resistor calculator - so you always know how much resistance you require for your pet projects and DIY goodness.
TODO:
---- Memory leak to be cleaned up ---- Add 5 band resistor calculator on rotate ---- Better functions and callbacks (very basic at the moment) for calculating resistance ---- Remove hackiness
WHAT TOOK AGES:
---- calculating with obj-c. pow(x, y) is completely different to powf(x,y) ---- UIPickerView was has a few 'fun' bits "data delegates and view options" which took a bit of getting used to
