Sorry to be so late in responding to your 2 new circuits. Please excuse me. I have been working on several non-Lectron (gasp!) projects and have not been here in almost a month.
For some reason, I am not getting notified of forum updates. I will have to look into this!
So glad to see the LDR featured in your two circuits! They were used creatively in a legacy Lectron System model – the Kybernetik 1 featuring a light driven ‘car’.
