Once this is done however there may be a way to convert it into a really neat professionally drawn schematic. Second, the drawing would have to be scanned or photographed first anyway. Some draw inductors that look like resistors, and some draw caps differently. To get it into a really nice and neat form however brings in some problems.įirst, not everyone draws symbols the same. We get a drawing that is just as sloppy as the original. Of course these techniques are not ideal either. You take a snapshot, store in in some directory. The second is to use a high resolution camera. This creates a drawing that is exactly like the hand drawing. The first is to scan it with a fast scanner. There are two direct ways to do this that i know of, if you dont need it to be in a perfectly neat form like a drawing that originated in software such as in LT Spice. But then again, it has come up, and i have thought about it a little myself because i had many hand drawings of circuits from the past that would be nice to have converted into pure digital format, complete with neat and tidy symbols for all the components like resistors and capacitors and transistors. That seems infrequent, but i think that is because most people just assume that it cant be done so they dont even ask. I've seen this question come up about 3 or 4 times in the past 10 years.
