Just for the heck of it, I'd like to build a slow calculator. Say, you press 2+2 and it takes like 10 seconds to compute. Is this posssible? I'd be a cool and funny project. Thanks!
Actually, this is probably really hard to do. Last time I saw inside an ordinary, non-scientific calculator, it was just a board with a little resin blob on it, everything was in there.
You may find it works much slower is you lower the supply voltage. Some seem to, some dont. So, it may be as simple as placing a resistor after the battery.
It certainly would be funny, if it worked :lol: , give it to someone to borrow, then see how long it is before they give it back; and try and find another one.
An clock in an thingy that makes an high freq. scuvare wave signal that is used to set the speed of the caculators procesor (well its an wery primitive type of an procesor)
If this square wave was 1-10 Hz you cod somtimes caculate it faster the it does (what is you wod set your PCs clock to 10 Hz LOL)
But this is a problem by caculators since they have evriting on the IC (that strange blob) but there is almost always an crystal on the circuit.
Baysicly ass you lock at the circuit there is noting on the cicuit but the IC,some caps,a crictal,button matrix and an batery
Yes BUT the oscilator circuit is on the IC only the crystal is outside the it!
I riped a cuple of caculators a part (ones i got for free) and all i seen i it was the black blob(the IC),1-3 Caps,1-3 resistors,a crystal,batery and a key matrix
