Microwave Tweaker


This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.

This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.

Please do not email me about this project without reading the disclaimer above.

This is a very easy beginner project.


Microwave ovens come in various ratings from 600 to 1500 watts. The timings in recipes assume you have a particular size oven. If, for example, the recipe presumes you have a 600 watt oven and you actually have a 1200 watt oven, you must reduce the timings by multiplying them by 600/1200.

You write a little app that lets you configure the size of your oven. To use it, you enter the assumed oven size in the recipe and the recipe time, and it displays the tweaked time.

When you get this working on a desktop computer, port it to run on an Android cell phone.

You could extend the project by allowing you to add commonly used items, e.g. cheese sandwich, and have it remember the time. Often the times on packages are in microscopic type.
