trying to hide a programmable calculator inside a regular school calculator to use in tests? Answered

hi all
I am not allowed to use a programmable calculator in exams, however we are allowed a scientific calculator.
is there any way to convert one or mod a programmable calculator to look like a regular school calculator?



Sorry, but I find the idea of cheating like this reprehensible.

The op managed to misspell 'cheet' in the keywords. This person needs to aim at their scholastic needs first methinks.

I sometimes wish I had the means to really identify people. I'd love to alert his school. I've seen far too many people in the professional world who are under-qualified and promoted through networking to positions in which they make huge mistakes and leave other coworkers handling the fallout.

I think your best bet is to take the electronic guts of a programing calculator and wedge it into the case of an approved calculator. The problem you're going to run into is that the programing one will probably have a lot more buttons and a larger dot matrix display instead of a simple single line numeric one.

It would be possible to make one of the keys into a 'shift' key that would allow you to utilize all the functions. This will be a very difficult tack and will definitely require a microcontroler to read the keyswitch matrix and send the correct keycodes to the calculator. The other option would be to not wire up the keys that correspond to functions you will be using on this test. This would save a lot of effort, however you will probably need to completely rewire the keyboard switch matrix to get the functions you need. This will not be easy.

Even if you pull off the above, I don't know what you are going to do about the display. If it's a multi line dot matrix, you are never going to make that look like the original one. The only chance would be if the display could be hidden under a panel that could be removed. Unless you have a lot of time to work on the case, this isn't really practical.

All things considered, I think you would be wise to simply study for the test by practicing the calculations you now do with your programing calculator with a scientific one.

That said, if you did mange to pull this off and I was your teacher (YMMV), you would get an automatic A, and be turned over to the nearest electrical engineering teacher for more in-depth instruction. I don't encourage you cheat, but I would seriously encourage you to try the mod just to see if you can do it.

Yes, it can be done.

No, we don't have the time, inclination, or willingness to help you cheat.

The time required to make a modification that wouldn't be obvious would exceed the time required to actually learn the given math required for a question.

Unsure, +1, and +10.

Seriously, kid, you REALLY want to learn the math. Cheating now will just put you in even worse trouble next time.

It would be easier to memorize all the answers. But, on the other hand, If you're not cheatin', your not tryin'.
