How do I get past the windmill/morse code puzzle? I have got the light turned on, and fiddled with the lenses until they are focussed. My problem is that I can't seem to distinguish between DASH DASH DASH and DASH [start new word] DASH [start new word] DASH [start new word]
I don't know if you've been able to solve it for yourself yet, but you use the left lever to start and finish each letter and the right lever to determine whether it's a dot or dash.
Press the left lever up to start the letter, if you need a dash then the right lever should be down, if it's a dot, push it up and when you've done all dots and dashes pull the left lever back down to finish the letter.
I've only just played through again and thought I'd have a look at the forums, so sorry this reply wasn't sooner.
