Great project, thanks for posting it!
> What kind of details do you want to know?
What is the limiting factor on the precision - is it just the specs of the TDC-GP21 or something else?
How did you calculate the appropriate laser lens and standoff?
Is the CS mount lens's focal length important, or is there no need for a sharp image at all distances?
Why use one CS-mount lens and one M12 lens, rather than two M12 lenses?
Do you need any sort of dynamic gain or optical filtering on the received signal? Is it vulnerable to getting washed out by bright sunlight?
Did you need much fancy $$$$ test equipment to get the design working, or did you achieve it with tools mere mortals can afford?
