Do you work in the field of engineering or any other types of consumer electronics? Or perhaps you want to work in one?
Look no further as you can “enhance” your status with this dot-matrix LED business card. Of course, it’s going to cost you a bunch of money to make couple of these but you might just get that “job” for standing out of the crowd.
how about one with a full graphical display on it that can be customised for a number of scrolling messages? This one could be made in quantity for about a $5 parts cost, and it is only a little bit more expensive if you are making just a few. I won’t kid you that this is an easy design to make – don’t try it unless you have very good soldering skills and some experience in electronics. Some of the components here are smaller than grains of rice, so it would be useful to have good eyesight as well!
