I started Rezistr in my final year of college as my senior project to demonstrate the image processing capabilities of a phone's mobile processor and camera. By the time I graduated I put out a limited working demonstration, but it still had potential to grow. I've since picked up the project and re-coded it from the ground up to become a publicly available app for iPhone users to use.

Rezistr isn't perfect, but if I can help even a handful of engineers or electricians to be more productive then I consider it a success.


Do it faster

Stop looking up resistor color charts and move on to what's important. Leave the calculating to Rezistr.
