Mates,
I invested few more hours into my Fyoog today!
You need to have a close look from the front to see the change:
But on the back there is a lever:
Which can be moved from left to right - surprise surprise:
And when we switch of the sun....
I was my first time using LEDs and a soldering gun. Lessons learned: Touching the front of the gun hurts and does not make much sense...
Cheers
