![]() ![]() ![]() I am going to show you some of the things you need to know to reverse engineer.Īlthough through hole circuit boards and SMD circuit boards look quite different they work the same way and they are reverse engineered the same way. You can hand draw your schematics, build them in paint like I do, or build your schematics a circuit simulator like 123D Circuits where they are easy to read and you can test them making sure you made the schematic correctly. Other than the resin covered custom IC the rest of the circuit was easy to trace and make a schematic of taking me just four hours. Take the flash circuit in this Polaroid Camera, if you wanted to model a capacitor charger after the flash circuit in this camera, unless you worked for Polaroid your chances of getting a schematic are next to impossible. Many people working on electronic equipment search to no end for schematics for a device when if they knew how it in all probability it would take less time to make their own schematics and parts lists. Reverse engineering is a skill that is not taught in college or university electronics courses and yet it is a valuable tool in an engineer’s tool belt. ![]() Many of the members here at Instructables ask about datasheets or pin outs of a device or display in answers, unfortunately you cant always get a datasheet and schematics, in these cases you only have one choice reverse engineering.
