[:D] If anyone has a solution for the following could they post it? 3 Led's. 2 Sequences. The first sequence is led 1on, led1 off, led2 on, led 2 off, led3 on, led 3 off. Then change to sequence 2, which is led 1on, led1 off, led2 on, led 2 off, led3 on, led 3 off and return back to sequence 1. Sequence one is on for 1/3 second and off for 1/3 second. Sequence 2 is on for 1 second and off for one second. For those old enough it is just the SOS ( dot, dot, dot, dash, dash, dash, dot, dot, dot, dash, dash, dash.....) pattern. A simple on off switch and a nine volt battery completes it. I have tried to get away with 2 transistors but I loose the timing. The timing is not critical and can decay with power loss from the battery, but it needs to a 1:3 ratio between sequence 1 and 2. If anyone has a circuit diagram or can whip one up then great electronic Karma will come your way if you can post it.
