DIY Laser levelling using webcam and laser level

Hi John,

Yes all good here thanks just very busy on other projects and work.

On getting the error signal out of the java app and into your hardware there are two choices,
1. Integrate a serial library,
2. Make a small change to the app to print the error to standard out and then pipe this directly into a serial comm port.

I don't really have time to do this or test it right now but someone else could have a go, (2) is much easier if you don't want to mess about with the code too much, there is a tutorial on windows comm port piping here:

Cheers, Joe

Thanks devmonkey, I hadn't thought of the standard out, I will give it a go.

btw, if you have the code you compiled to run on linux / raspberry pi that might help for the next chapter.

regards

Lee
