We’re changing it up this week with a reverse engineering fail which [Itay] pointed out to us. A couple of years ago [Nate] over at Sparkfun agreed to help a friend with a project that required precise distance measurement. He knew that laser rangefinders are a good way to go and mentions their use in golfing and the building trades. He picked up this handheld version billed as a laser tape measure. He put up a valiant effort to reverse engineer the PCB in hopes of finding a hook for the measurement data.
Obviously his endeavor failed or we wouldn’t be talking about it in this column. But there’s a lot to learn about his methods, and a few of the comments associated with his original post help to shed light on a couple of extra things to try.
