Budget Keeper Fridgemagnet, is this doable? Answered

Howdy folks, I have an idea for a budget "keeper" and I'd like to know if it is doable. Here's my idea: Make a small (5"x7" maximum) lightweight budget calculator that goes on your fridge. It will keep "budget limits" for a few categories: Grocery, Fast-food, Non-Food, Car and "other". expenses. The intent is that at the beginning of the month you'd enter your budget limits for each category. Then when you get home each time after spending some money you'd enter in what category you spent in and how much. Then it would tell you how much you have left! This would be so useful to me! Maybe others? I'm not a circuitry/soldering kinda guy, but I am a C#/VB programmer, so I could write the logic on that level. Is this something that is doable from an "instructables" point of view? Thanks!

. I'd think that just about any "scientific" calculator with enough "user registers" would work. Since most calculators don't use text labels for the registers, you will have to remember that R0=utils, R1=food, &c.
. A programmable calculator will probably work better, especially if you get one with a multi-line/graphical display.

Definitely doable. But I find the envelope method is infinitely easier. Once you budget, take out cash for groceries, gas, etc and place in separate marked envelopes. There's no numbers to keep track of, and you never spend more money than you have. We've tried something like 6 other budgeting methods, and this is the only one that was easy enough for me to keep up with.

:D So smart! That's actually what I'm doing now! :) Just looking for a techy solution I guess. ;)

Seems like you could do the same thing with a small dry erase board. At the beginning of each month you write the budget for each category. Every time you have a new receipt or entry you subtract it from the remaining budget and there you go. Just stick a calculator next to it for easy subtraction and you're done.

So, how do I poll to see if anyone *wants* to do this?

Using the proper PROM I am sure it is doable. I haven't yet gotten into much on the side of programming my own chips yet, so I am without details of method.
